Refer to the complete mechanical drawings and notes when planning installation. Model and Inverter Output Complete model NTN-5K-148CAN Series NTN-5K Continuous output power 4000 W Nominal DC input voltage 48 VDC Default AC output voltage 110 VAC Overpower rating, 3 minutes 4600 W Peak output, 10 seconds 6000 W Surge output, 30 AC cycles 8000 W Selectable AC output voltages 100 / 110 / 115 / 120 VAC Factory frequency 60 ±0.1 Hz Selectable frequencies 50 / 60 Hz Output waveform True sine wave; THD <3% AC voltage regulation ±3% Typical inverter efficiency 91% The 148 code selects the 110 VAC output group and 48 VDC battery-input version. The CAN suffix selects CANBus communication. Efficiency, AC regulation and THD are specified at 75% linear load with 50 VDC input. Unless otherwise stated, measurements use 50 VDC input, 25°C ambient and factory settings. AC regulation is stated at rated input. Short-duration power is separate from the continuous rating; size the installation for the applicable input-voltage and temperature limits. Battery Input and Low-Load Operation Typical DC input range 38–66 VDC Typical DC input current 100 A Typical no-load current, non-saving mode 1.4 A Typical saving-mode consumption <25 W Off-mode input current ≤2 mA Compatible battery types are flooded, Gel and AGM lead-acid, or Li-ion. Select charge settings and protective thresholds to suit the battery manufacturer’s requirements. Saving mode is disabled at the factory. When enabled, the unit enters saving mode automatically at AC loads of 10 W or less. Saving mode is available only for an independently operating unit with its PRL switch ON; do not apply this mode to a parallel system. AC Charging and UPS Bypass Default boost charge voltage 57.6 V Default float charge voltage 55.2 V Charging voltage adjustment 40–60 V Maximum constant charging current 60 A Maximum charging power 3600 W Typical charging efficiency 91% Typical charging power factor >0.98 at 115 VAC, full load Typical AC charging input current 20 A at 110 VAC Typical AC charging inrush current 25 A at 110 VAC Peak AC leakage current 4.7 mA at 264 VAC AC utility frequency range 45–65 Hz Typical transfer time 10 ms, inverter ↔ AC bypass AC utility acceptance is ±16% of the selected 100 / 110 / 115 / 120 VAC setting; recovery is within ±13%. The default UPS mode supplies the load directly from available AC utility power while charging the battery. The alternative energy-saving operating mode is described in the manufacturer’s operating-logic instructions. Default three-stage charging starts at constant current, then holds the boost voltage while current decreases, and finally maintains the float voltage. The curve marks the CV-to-float transition at 10% of charging current. Charge-stage indication flashes orange in constant-current/constant-voltage operation and green in float. Adjust charging parameters through CANBus within the stated range. The supplied battery-temperature sensor supports charging-voltage compensation in three-stage lead-acid charging over 0–40°C. Connect the sensor to the battery using the supplied mating lead and a suitable customer extension: NTC pin 1 is RTH− and pin 2 is RTH+. The charger continues normal operation if the sensor is not used. Battery and Output Protection Low-battery alarm 44 ±1 V Low-battery shutdown 38 ±1 V Low-battery restart 50 ±1 V High-battery alarm 62 ±1 V High-battery shutdown 66 ±1 V High-battery restart 60 ±1 V AC circuit breaker 50 A For reversed DC polarity, the protection is specified as causing no damage; remove the fault and re-power the unit. Typical overload protection shuts down the output at 105–115% for 180 seconds or 115–150% for 10 seconds; re-power the unit after correcting the fault. Apply the model-specific peak-power ratings separately rather than treating these protection thresholds as continuous output ratings. AC output short-circuit protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after the temperature falls. Low-battery shutdown helps prevent excessive battery discharge. Temperature, Input Derating and Environment Operating temperature −30 to +70°C, with derating Operating humidity 20–90% RH, non-condensing Storage temperature and humidity −30 to +70°C; 10–95% RH, non-condensing The horizontal-mounting temperature curve permits 100% load from −30°C through 40°C, then 80% at 50°C, 50% at 60°C and 25% at 70°C. The temperature-controlled fan must have an unobstructed airflow path. The DC-input curve permits 50% load at 38 VDC, 75% at 41 VDC and 100% from 42 through 66 VDC. Apply DC-input and ambient-temperature derating together. Vibration test conditions are 10–500 Hz at 3 G, 10 minutes per cycle, for 60 minutes along each X, Y and Z axis. DIP Settings and Remote Control SW2 selects voltage, frequency and standby saving. S1/S2 OFF/OFF selects 100 VAC; OFF/ON selects 110 VAC; ON/OFF selects 115 VAC; ON/ON selects 120 VAC. S3 ON selects 50 Hz and OFF selects 60 Hz. S4 ON enables saving mode and OFF selects non-saving mode. AC-output remote control uses the PAR1 or PAR2 dry-contact connection between pin 1 (+5V_AUX2) and pin 3 (REMOTE ON/OFF): short for AC output ON, open for AC output OFF. The separate four-pin Power ON/OFF connector controls the whole unit: short pins 1–2 and pins 3–4 for power ON; leave pins 1–4 open for power OFF. Use the supplied switch/connector leads and the manufacturer connection drawing. Parallel and Multi-Phase Systems Built-in active current sharing supports up to six compatible units in parallel. Use short, large-diameter output wiring before the common load connection. For fewer than six units, maximum total output current is rated current per unit × number of units × 95%. Use the manufacturer’s six-unit system instructions for that configuration. Use PAR1/PAR2 to connect the parallel-control bus. For one standalone unit, the parallel connection is unused and PRL is ON. For two units, both PRL switches are ON. For three to six units, the first and last PRL switches are ON and all intermediate PRL switches are OFF. Twist long parallel-control conductors in pairs to reduce noise. For a three-phase, four-wire Y system, use SW1 S1/S2 OFF/OFF for L1 at 0°, OFF/ON for L2 at −120°, and ON/OFF for L3 at +120°. Each line-to-neutral voltage is the selected output voltage, and line-to-line voltage is √3 times that voltage. Follow the manufacturer’s three-phase wiring instructions. This 124/148 version also supports a two-unit single-phase, three-wire split-phase system: SW1 OFF/OFF sets L1 at 0° and ON/ON sets L2 at +180°. Each line-to-neutral voltage is the selected output voltage; line-to-line voltage is twice it. This unit is rated 4000 W continuously. Size a parallel bank from that per-unit rating and the applicable current-sharing and installation limits. Communication and Signal Connections COMM is an isolated CANBus interface referenced to GND-AUX: pin 1 GND-AUX; pin 2 CANH; pin 3 CANL; pin 4 +5V_AUX, 4.5–5.5 V relative to pin 1. Use AD1 and AD2 for the communication address according to the user manual. The CRL connector enables 120 Ω communication-bus termination when pins 1 and 3 are shorted. When communication is not required, the catalogue calls for a jumper on pins 2 and 4. PAR1 and PAR2 each use pin 1 +5V_AUX2 (4.5–5.5 V, only for remote ON/OFF), pin 2 GND_AUX2, pin 3 REMOTE ON/OFF, pin 4 SOLAR_ON_OFF for external MPPT-charger control, pin 5 DA, pin 6 SYNC_BUS, pin 7 DB and pin 8 SYNC_BUS2. These isolated signals reference GND_AUX2; the COMM ground reference is separately identified as GND-AUX. The four-pin Power ON/OFF header is HRS DF11-04DP-2DS or equivalent, with HRS DF11-04DS mating housing. PAR1/PAR2 headers are HRS DF11-08DP-2DS or equivalent, with HRS DF11-08DS mating housings. The connector table specifies HRS DF11-**SC or equivalent contacts; select the exact contact variant for the wire and housing being assembled. CMU2E and CMU2E-R are optional monitoring/control units listed for checking inverter status and adjusting output settings. Select the controller and communication arrangement appropriate to this model; they are separate from the standard accessories listed below. Indicators Status LED: steady green means inverter OK; flashing green means system check; steady orange means remote OFF; flashing orange means saving mode; red indicates an abnormal condition. DC Input LED: steady green is 50–62 VDC; steady orange is 44–50 VDC; steady red is below 44 VDC or above 62 VDC. Flashing green indicates maintenance/float charging and flashing orange indicates charging. Load LED is green below 40%, orange at 40–80% and red above 80% load. These colors are steady in inverter mode and flashing in bypass mode. AC Input LED is steady green for utility OK, flashing green for utility error and off when utility is disconnected. Fault patterns: overload or AC short circuit gives steady red Status, DC Input off and flashing red Load. Abnormal DC voltage gives steady red Status, flashing red DC Input and Load off. Overtemperature or fan lock gives steady red Status with both DC Input and Load flashing red. Inverter failure gives flashing red Status with DC Input and Load off.

The supplied battery-temperature sensor supports charging-voltage compensation in three-stage lead-acid charging over 0–40°C. Connect the sensor to the battery using the supplied mating lead and a suitable customer extension: NTC pin 1 is RTH− and pin 2 is RTH+. The charger continues normal operation if the sensor is not used. Battery and Output Protection Low-battery alarm 44 ±1 V Low-battery shutdown 38 ±1 V Low-battery restart 50 ±1 V High-battery alarm 62 ±1 V High-battery shutdown 66 ±1 V High-battery restart 60 ±1 V AC circuit breaker 50 A For reversed DC polarity, the protection is specified as causing no damage; remove the fault and re-power the unit. Typical overload protection shuts down the output at 105–115% for 180 seconds or 115–150% for 10 seconds; re-power the unit after correcting the fault. Apply the model-specific peak-power ratings separately rather than treating these protection thresholds as continuous output ratings. AC output short-circuit protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after the temperature falls. Low-battery shutdown helps prevent excessive battery discharge. Temperature, Input Derating and Environment Operating temperature −30 to +70°C, with derating Operating humidity 20–90% RH, non-condensing Storage temperature and humidity −30 to +70°C; 10–95% RH, non-condensing The horizontal-mounting temperature curve permits 100% load from −30°C through 40°C, then 80% at 50°C, 50% at 60°C and 25% at 70°C. The temperature-controlled fan must have an unobstructed airflow path. The DC-input curve permits 50% load at 38 VDC, 75% at 41 VDC and 100% from 42 through 66 VDC. Apply DC-input and ambient-temperature derating together. Vibration test conditions are 10–500 Hz at 3 G, 10 minutes per cycle, for 60 minutes along each X, Y and Z axis. DIP Settings and Remote Control SW2 selects voltage, frequency and standby saving. S1/S2 OFF/OFF selects 100 VAC; OFF/ON selects 110 VAC; ON/OFF selects 115 VAC; ON/ON selects 120 VAC. S3 ON selects 50 Hz and OFF selects 60 Hz. S4 ON enables saving mode and OFF selects non-saving mode. AC-output remote control uses the PAR1 or PAR2 dry-contact connection between pin 1 (+5V_AUX2) and pin 3 (REMOTE ON/OFF): short for AC output ON, open for AC output OFF. The separate four-pin Power ON/OFF connector controls the whole unit: short pins 1–2 and pins 3–4 for power ON; leave pins 1–4 open for power OFF. Use the supplied switch/connector leads and the manufacturer connection drawing. Parallel and Multi-Phase Systems Built-in active current sharing supports up to six compatible units in parallel. Use short, large-diameter output wiring before the common load connection. For fewer than six units, maximum total output current is rated current per unit × number of units × 95%. Use the manufacturer’s six-unit system instructions for that configuration. Use PAR1/PAR2 to connect the parallel-control bus. For one standalone unit, the parallel connection is unused and PRL is ON. For two units, both PRL switches are ON. For three to six units, the first and last PRL switches are ON and all intermediate PRL switches are OFF. Twist long parallel-control conductors in pairs to reduce noise. For a three-phase, four-wire Y system, use SW1 S1/S2 OFF/OFF for L1 at 0°, OFF/ON for L2 at −120°, and ON/OFF for L3 at +120°. Each line-to-neutral voltage is the selected output voltage, and line-to-line voltage is √3 times that voltage. Follow the manufacturer’s three-phase wiring instructions. This 124/148 version also supports a two-unit single-phase, three-wire split-phase system: SW1 OFF/OFF sets L1 at 0° and ON/ON sets L2 at +180°. Each line-to-neutral voltage is the selected output voltage; line-to-line voltage is twice it. This unit is rated 4000 W continuously. Size a parallel bank from that per-unit rating and the applicable current-sharing and installation limits. Communication and Signal Connections COMM is an isolated MODBus-RTU (RS-485) interface referenced to GND-AUX: pin 1 GND-AUX; pin 2 D+; pin 3 D−; pin 4 +5V_AUX, 4.5–5.5 V relative to pin 1. Use AD1 and AD2 for the communication address according to the user manual. The CRL connector enables 120 Ω communication-bus termination when pins 1 and 3 are shorted. When communication is not required, the catalogue calls for a jumper on pins 2 and 4. PAR1 and PAR2 each use pin 1 +5V_AUX2 (4.5–5.5 V, only for remote ON/OFF), pin 2 GND_AUX2, pin 3 REMOTE ON/OFF, pin 4 SOLAR_ON_OFF for external MPPT-charger control, pin 5 DA, pin 6 SYNC_BUS, pin 7 DB and pin 8 SYNC_BUS2. These isolated signals reference GND_AUX2; the COMM ground reference is separately identified as GND-AUX. The four-pin Power ON/OFF header is HRS DF11-04DP-2DS or equivalent, with HRS DF11-04DS mating housing. PAR1/PAR2 headers are HRS DF11-08DP-2DS or equivalent, with HRS DF11-08DS mating housings. The connector table specifies HRS DF11-**SC or equivalent contacts; select the exact contact variant for the wire and housing being assembled. CMU2E and CMU2E-R are optional monitoring/control units listed for checking inverter status and adjusting output settings. Select the controller and communication arrangement appropriate to this model; they are separate from the standard accessories listed below. Indicators Status LED: steady green means inverter OK; flashing green means system check; steady orange means remote OFF; flashing orange means saving mode; red indicates an abnormal condition. DC Input LED: steady green is 50–62 VDC; steady orange is 44–50 VDC; steady red is below 44 VDC or above 62 VDC. Flashing green indicates maintenance/float charging and flashing orange indicates charging. Load LED is green below 40%, orange at 40–80% and red above 80% load. These colors are steady in inverter mode and flashing in bypass mode. AC Input LED is steady green for utility OK, flashing green for utility error and off when utility is disconnected. Fault patterns: overload or AC short circuit gives steady red Status, DC Input off and flashing red Load. Abnormal DC voltage gives steady red Status, flashing red DC Input and Load off. Overtemperature or fan lock gives steady red Status with both DC Input and Load flashing red. Inverter failure gives flashing red Status with DC Input and Load off.

A blank communication suffix selects MODBus-RTU over RS-485. Efficiency, AC regulation and THD are specified at 75% linear load with 25 VDC input. Unless otherwise stated, measurements use 25 VDC input, 25°C ambient and factory settings. AC regulation is stated at rated input. Short-duration power is separate from the continuous rating; size the installation for the applicable input-voltage and temperature limits.

For one standalone unit, the parallel connection is unused and PRL is ON. For two units, both PRL switches are ON. For three to six units, the first and last PRL switches are ON and all intermediate PRL switches are OFF. Twist long parallel-control conductors in pairs to reduce noise. For a three-phase, four-wire Y system, use SW1 S1/S2 OFF/OFF for L1 at 0°, OFF/ON for L2 at −120°, and ON/OFF for L3 at +120°. Each line-to-neutral voltage is the selected output voltage, and line-to-line voltage is √3 times that voltage. Follow the manufacturer’s three-phase wiring instructions. Split-phase operation is specified only for the 124 and 148 output versions; it is not a function of this 230 VAC output model. The series headline of up to 30 kW refers to a suitable 5000 W, 5+1-unit configuration. Apply the actual per-unit rating and all parallel/installation limits. Communication and Signal Connections COMM is an isolated CANBus interface referenced to GND-AUX: pin 1 GND-AUX; pin 2 CANH; pin 3 CANL; pin 4 +5V_AUX, 4.5–5.5 V relative to pin 1. Use AD1 and AD2 for the communication address according to the user manual. The CRL connector enables 120 Ω communication-bus termination when pins 1 and 3 are shorted. When communication is not required, the catalogue calls for a jumper on pins 2 and 4. PAR1 and PAR2 each use pin 1 +5V_AUX2 (4.5–5.5 V, only for remote ON/OFF), pin 2 GND_AUX2, pin 3 REMOTE ON/OFF, pin 4 SOLAR_ON_OFF for external MPPT-charger control, pin 5 DA, pin 6 SYNC_BUS, pin 7 DB and pin 8 SYNC_BUS2. These isolated signals reference GND_AUX2; the COMM ground reference is separately identified as GND-AUX. The four-pin Power ON/OFF header is HRS DF11-04DP-2DS or equivalent, with HRS DF11-04DS mating housing. PAR1/PAR2 headers are HRS DF11-08DP-2DS or equivalent, with HRS DF11-08DS mating housings. The connector table specifies HRS DF11-**SC or equivalent contacts; select the exact contact variant for the wire and housing being assembled. CMU2E and CMU2E-R are optional monitoring/control units listed for checking inverter status and adjusting output settings. Select the controller and communication arrangement appropriate to this model; they are separate from the standard accessories listed below. Indicators Status LED: steady green means inverter OK; flashing green means system check; steady orange means remote OFF; flashing orange means saving mode; red indicates an abnormal condition. DC Input LED: steady green is 335–420 VDC; steady orange is 300–335 VDC; steady red is below 300 VDC or above 420 VDC. Flashing green indicates maintenance/float charging and flashing orange indicates charging. Load LED is green below 40%, orange at 40–80% and red above 80% load. These colors are steady in inverter mode and flashing in bypass mode. AC Input LED is steady green for utility OK, flashing green for utility error and off when utility is disconnected. Fault patterns: overload or AC short circuit gives steady red Status, DC Input off and flashing red Load. Abnormal DC voltage gives steady red Status, flashing red DC Input and Load off. Overtemperature or fan lock gives steady red Status with both DC Input and Load flashing red. Inverter failure gives flashing red Status with DC Input and Load off.

MEAN WELL NTN-5K-248CAN combines a 5000 W continuous true sine wave inverter, an AC battery charger and UPS bypass in one unit. It uses a 48 VDC nominal battery system and is factory set to 230 VAC / 50 Hz. This complete model has CANBus communication. Solar charging uses an external MPPT charger connected to the battery system. Product Datasheet Download MEAN WELL NTN-5K Datasheet (PDF) The NTN-5K section is on PDF pages 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13. Refer to the complete mechanical drawings and notes when planning installation. Model and Inverter Output Complete model NTN-5K-248CAN Series NTN-5K Continuous output power 5000 W Nominal DC input voltage 48 VDC Default AC output voltage 230 VAC Overpower rating, 3 minutes 5750 W Peak output, 10 seconds 7500 W Surge output, 30 AC cycles 10000 W Selectable AC output voltages 200 / 220 / 230 / 240 VAC Factory frequency 50 ±0.1 Hz Selectable frequencies 50 / 60 Hz Output waveform True sine wave; THD <3% AC voltage regulation ±3% Typical inverter efficiency 93% The 248 code selects the 230 VAC output group and 48 VDC battery-input version. The CAN suffix selects CANBus communication. Efficiency, AC regulation and THD are specified at 75% linear load with 50 VDC input. Unless otherwise stated, measurements use 50 VDC input, 25°C ambient and factory settings. AC regulation is stated at rated input. Short-duration power is separate from the continuous rating; size the installation for the applicable input-voltage and temperature limits. Battery Input and Low-Load Operation Typical DC input range 38–66 VDC Typical DC input current 120 A Typical no-load current, non-saving mode 1.4 A Typical saving-mode consumption <25 W Off-mode input current ≤2 mA Compatible battery types are flooded, Gel and AGM lead-acid, or Li-ion. Select charge settings and protective thresholds to suit the battery manufacturer’s requirements. Saving mode is disabled at the factory. When enabled, the unit enters saving mode automatically at AC loads of 10 W or less. Saving mode is available only for an independently operating unit with its PRL switch ON; do not apply this mode to a parallel system. AC Charging and UPS Bypass Default boost charge voltage 57.6 V Default float charge voltage 55.2 V Charging voltage adjustment 40–60 V Maximum constant charging current 70 A Maximum charging power 4200 W Typical charging efficiency 93% Typical charging power factor >0.98 at 230 VAC, full load Typical AC charging input current 25 A at 230 VAC Typical AC charging inrush current 50 A at 230 VAC Peak AC leakage current 4.7 mA at 264 VAC AC utility frequency range 45–65 Hz Typical transfer time 10 ms, inverter ↔ AC bypass AC utility acceptance is ±16% of the selected 200 / 220 / 230 / 240 VAC setting; recovery is within ±13%. The default UPS mode supplies the load directly from available AC utility power while charging the battery. The alternative energy-saving operating mode is described in the manufacturer’s operating-logic instructions. Default three-stage charging starts at constant current, then holds the boost voltage while current decreases, and finally maintains the float voltage. The curve marks the CV-to-float transition at 10% of charging current. Charge-stage indication flashes orange in constant-current/constant-voltage operation and green in float. Adjust charging parameters through CANBus within the stated range. The supplied battery-temperature sensor supports charging-voltage compensation in three-stage lead-acid charging over 0–40°C. Connect the sensor to the battery using the supplied mating lead and a suitable customer extension: NTC pin 1 is RTH− and pin 2 is RTH+. The charger continues normal operation if the sensor is not used. Battery and Output Protection Low-battery alarm 44 ±1 V Low-battery shutdown 38 ±1 V Low-battery restart 50 ±1 V High-battery alarm 62 ±1 V High-battery shutdown 66 ±1 V High-battery restart 60 ±1 V AC circuit breaker 35 A For reversed DC polarity, the protection is specified as causing no damage; remove the fault and re-power the unit. Typical overload protection shuts down the output at 105–115% for 180 seconds or 115–150% for 10 seconds; re-power the unit after correcting the fault. Apply the model-specific peak-power ratings separately rather than treating these protection thresholds as continuous output ratings. AC output short-circuit protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after the temperature falls. Low-battery shutdown helps prevent excessive battery discharge. Temperature, Input Derating and Environment Operating temperature −30 to +70°C, with derating Operating humidity 20–90% RH, non-condensing Storage temperature and humidity −30 to +70°C; 10–95% RH, non-condensing The horizontal-mounting temperature curve permits 100% load from −30°C through 40°C, then 80% at 50°C, 50% at 60°C and 25% at 70°C. The temperature-controlled fan must have an unobstructed airflow path. The DC-input curve permits 50% load at 38 VDC, 75% at 41 VDC and 100% from 42 through 66 VDC. Apply DC-input and ambient-temperature derating together. Vibration test conditions are 10–500 Hz at 3 G, 10 minutes per cycle, for 60 minutes along each X, Y and Z axis. DIP Settings and Remote Control SW2 selects voltage, frequency and standby saving. S1/S2 OFF/OFF selects 200 VAC; OFF/ON selects 220 VAC; ON/OFF selects 230 VAC; ON/ON selects 240 VAC. S3 ON selects 50 Hz and OFF selects 60 Hz. S4 ON enables saving mode and OFF selects non-saving mode. AC-output remote control uses the PAR1 or PAR2 dry-contact connection between pin 1 (+5V_AUX2) and pin 3 (REMOTE ON/OFF): short for AC output ON, open for AC output OFF. The separate four-pin Power ON/OFF connector controls the whole unit: short pins 1–2 and pins 3–4 for power ON; leave pins 1–4 open for power OFF. Use the supplied switch/connector leads and the manufacturer connection drawing. Parallel and Multi-Phase Systems Built-in active current sharing supports up to six compatible units in parallel. Use short, large-diameter output wiring before the common load connection. For fewer than six units, maximum total output current is rated current per unit × number of units × 95%. Use the manufacturer’s six-unit system instructions for that configuration. Use PAR1/PAR2 to connect the parallel-control bus.

MEAN WELL NTN-5K-2380 combines a 5000 W continuous true sine wave inverter, an AC battery charger and UPS bypass in one unit. It uses a 380 VDC nominal battery system and is factory set to 230 VAC / 50 Hz. This complete model has MODBus-RTU (RS-485) communication. Solar charging uses an external MPPT charger connected to the battery system. Product Datasheet Download MEAN WELL NTN-5K Datasheet (PDF) The NTN-5K section is on PDF pages 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13. Refer to the complete mechanical drawings and notes when planning installation. Model and Inverter Output Complete model NTN-5K-2380 Series NTN-5K Continuous output power 5000 W Nominal DC input voltage 380 VDC Default AC output voltage 230 VAC Overpower rating, 3 minutes 5750 W Peak output, 10 seconds 7500 W Surge output, 30 AC cycles 10000 W Selectable AC output voltages 200 / 220 / 230 / 240 VAC Factory frequency 50 ±0.1 Hz Selectable frequencies 50 / 60 Hz Output waveform True sine wave; THD <3% AC voltage regulation ±3% Typical inverter efficiency 94.5% The 2380 code selects the 230 VAC output group and 380 VDC battery-input version. A blank communication suffix selects MODBus-RTU over RS-485. Efficiency, AC regulation and THD are specified at 75% linear load with 400 VDC input. Unless otherwise stated, measurements use 400 VDC input, 25°C ambient and factory settings. AC regulation is stated at rated input. Short-duration power is separate from the continuous rating; size the installation for the applicable input-voltage and temperature limits. Battery Input and Low-Load Operation Typical DC input range 280–430 VDC Typical DC input current 16 A Typical no-load current, non-saving mode 0.2 A Typical saving-mode consumption <25 W Off-mode input current ≤2 mA Compatible battery types are flooded, Gel and AGM lead-acid, or Li-ion. Select charge settings and protective thresholds to suit the battery manufacturer’s requirements. Saving mode is disabled at the factory. When enabled, the unit enters saving mode automatically at AC loads of 10 W or less. Saving mode is available only for an independently operating unit with its PRL switch ON; do not apply this mode to a parallel system. AC Charging and UPS Bypass Default boost charge voltage 400 V Default float charge voltage 385 V Charging voltage adjustment 290–400 V Maximum constant charging current 11.3 A Maximum charging power 4520 W Typical charging efficiency 94% Typical charging power factor >0.98 at 230 VAC, full load Typical AC charging input current 25 A at 230 VAC Typical AC charging inrush current 50 A at 230 VAC Peak AC leakage current 4.7 mA at 264 VAC AC utility frequency range 45–65 Hz Typical transfer time 10 ms, inverter ↔ AC bypass AC utility acceptance is ±16% of the selected 200 / 220 / 230 / 240 VAC setting; recovery is within ±13%. The default UPS mode supplies the load directly from available AC utility power while charging the battery. The alternative energy-saving operating mode is described in the manufacturer’s operating-logic instructions. Default three-stage charging starts at constant current, then holds the boost voltage while current decreases, and finally maintains the float voltage. The curve marks the CV-to-float transition at 10% of charging current. Charge-stage indication flashes orange in constant-current/constant-voltage operation and green in float. Adjust charging parameters through MODBus-RTU (RS-485) within the stated range. The supplied battery-temperature sensor supports charging-voltage compensation in three-stage lead-acid charging over 0–40°C. Connect the sensor to the battery using the supplied mating lead and a suitable customer extension: NTC pin 1 is RTH− and pin 2 is RTH+. The charger continues normal operation if the sensor is not used. Battery and Output Protection Low-battery alarm 300 ±5 V Low-battery shutdown 280 ±5 V Low-battery restart 335 ±5 V High-battery alarm 420 ±5 V High-battery shutdown 430 ±5 V High-battery restart 400 ±5 V AC circuit breaker 35 A Reverse-polarity protection opens the internal fuse on this 380 VDC model. Typical overload protection shuts down the output at 105–115% for 180 seconds or 115–150% for 10 seconds; re-power the unit after correcting the fault. Apply the model-specific peak-power ratings separately rather than treating these protection thresholds as continuous output ratings. AC output short-circuit protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after the temperature falls. Low-battery shutdown helps prevent excessive battery discharge. Temperature, Input Derating and Environment Operating temperature −30 to +70°C, with derating Operating humidity 20–90% RH, non-condensing Storage temperature and humidity −30 to +70°C; 10–95% RH, non-condensing The horizontal-mounting temperature curve permits 100% load from −30°C through 40°C, then 80% at 50°C, 50% at 60°C and 25% at 70°C. The temperature-controlled fan must have an unobstructed airflow path. The DC-input curve permits 50% load at 280 VDC, 75% at 300 VDC and 100% from 335 through 430 VDC. Apply DC-input and ambient-temperature derating together. Vibration test conditions are 10–500 Hz at 3 G, 10 minutes per cycle, for 60 minutes along each X, Y and Z axis. DIP Settings and Remote Control SW2 selects voltage, frequency and standby saving. S1/S2 OFF/OFF selects 200 VAC; OFF/ON selects 220 VAC; ON/OFF selects 230 VAC; ON/ON selects 240 VAC. S3 ON selects 50 Hz and OFF selects 60 Hz. S4 ON enables saving mode and OFF selects non-saving mode. AC-output remote control uses the PAR1 or PAR2 dry-contact connection between pin 1 (+5V_AUX2) and pin 3 (REMOTE ON/OFF): short for AC output ON, open for AC output OFF. The separate four-pin Power ON/OFF connector controls the whole unit: short pins 1–2 and pins 3–4 for power ON; leave pins 1–4 open for power OFF. Use the supplied switch/connector leads and the manufacturer connection drawing. Parallel and Multi-Phase Systems Built-in active current sharing supports up to six compatible units in parallel. Use short, large-diameter output wiring before the common load connection. For fewer than six units, maximum total output current is rated current per unit × number of units × 95%. Use the manufacturer’s six-unit system instructions for that configuration. Use PAR1/PAR2 to connect the parallel-control bus. For one standalone unit, the parallel connection is unused and PRL is ON. For two units, both PRL switches are ON. For three to six units, the first and last PRL switches are ON and all intermediate PRL switches are OFF. Twist long parallel-control conductors in pairs to reduce noise. For a three-phase, four-wire Y system, use SW1 S1/S2 OFF/OFF for L1 at 0°, OFF/ON for L2 at −120°, and ON/OFF for L3 at +120°. Each line-to-neutral voltage is the selected output voltage, and line-to-line voltage is √3 times that voltage. Follow the manufacturer’s three-phase wiring instructions. Split-phase operation is specified only for the 124 and 148 output versions; it is not a function of this 230 VAC output model. The series headline of up to 30 kW refers to a suitable 5000 W, 5+1-unit configuration. Apply the actual per-unit rating and all parallel/installation limits. Communication and Signal Connections COMM is an isolated MODBus-RTU (RS-485) interface referenced to GND-AUX: pin 1 GND-AUX; pin 2 D+; pin 3 D−; pin 4 +5V_AUX, 4.5–5.5 V relative to pin 1. Use AD1 and AD2 for the communication address according to the user manual. The CRL connector enables 120 Ω communication-bus termination when pins 1 and 3 are shorted. When communication is not required, the catalogue calls for a jumper on pins 2 and 4. PAR1 and PAR2 each use pin 1 +5V_AUX2 (4.5–5.5 V, only for remote ON/OFF), pin 2 GND_AUX2, pin 3 REMOTE ON/OFF, pin 4 SOLAR_ON_OFF for external MPPT-charger control, pin 5 DA, pin 6 SYNC_BUS, pin 7 DB and pin 8 SYNC_BUS2. These isolated signals reference GND_AUX2; the COMM ground reference is separately identified as GND-AUX.

DC Input LED: steady green is 335–420 VDC; steady orange is 300–335 VDC; steady red is below 300 VDC or above 420 VDC. Flashing green indicates maintenance/float charging and flashing orange indicates charging. Load LED is green below 40%, orange at 40–80% and red above 80% load. These colors are steady in inverter mode and flashing in bypass mode. AC Input LED is steady green for utility OK, flashing green for utility error and off when utility is disconnected. Fault patterns: overload or AC short circuit gives steady red Status, DC Input off and flashing red Load. Abnormal DC voltage gives steady red Status, flashing red DC Input and Load off. Overtemperature or fan lock gives steady red Status with both DC Input and Load flashing red. Inverter failure gives flashing red Status with DC Input and Load off.

MEAN WELL NTN-5K-224 combines a 5000 W continuous true sine wave inverter, an AC battery charger and UPS bypass in one unit. It uses a 24 VDC nominal battery system and is factory set to 230 VAC / 50 Hz. This complete model has MODBus-RTU (RS-485) communication. Solar charging uses an external MPPT charger connected to the battery system. Product Datasheet Download MEAN WELL NTN-5K Datasheet (PDF) The NTN-5K section is on PDF pages 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13. Refer to the complete mechanical drawings and notes when planning installation. Model and Inverter Output Complete model NTN-5K-224 Series NTN-5K Continuous output power 5000 W Nominal DC input voltage 24 VDC Default AC output voltage 230 VAC Overpower rating, 3 minutes 5750 W Peak output, 10 seconds 7000 W Surge output, 30 AC cycles 8000 W Selectable AC output voltages 200 / 220 / 230 / 240 VAC Factory frequency 50 ±0.1 Hz Selectable frequencies 50 / 60 Hz Output waveform True sine wave; THD <3% AC voltage regulation ±3% Typical inverter efficiency 91% The 224 code selects the 230 VAC output group and 24 VDC battery-input version. A blank communication suffix selects MODBus-RTU over RS-485. Efficiency, AC regulation and THD are specified at 75% linear load with 25 VDC input. Unless otherwise stated, measurements use 25 VDC input, 25°C ambient and factory settings. AC regulation is stated at rated input. Short-duration power is separate from the continuous rating; size the installation for the applicable input-voltage and temperature limits. Battery Input and Low-Load Operation Typical DC input range 19–33 VDC Typical DC input current 240 A Typical no-load current, non-saving mode 2.5 A Typical saving-mode consumption <25 W Off-mode input current ≤2 mA Compatible battery types are flooded, Gel and AGM lead-acid, or Li-ion. Select charge settings and protective thresholds to suit the battery manufacturer’s requirements. Saving mode is disabled at the factory. When enabled, the unit enters saving mode automatically at AC loads of 10 W or less. Saving mode is available only for an independently operating unit with its PRL switch ON; do not apply this mode to a parallel system. AC Charging and UPS Bypass Default boost charge voltage 28.8 V Default float charge voltage 27.6 V Charging voltage adjustment 20–30 V Maximum constant charging current 135 A Maximum charging power 4050 W Typical charging efficiency 91% Typical charging power factor >0.98 at 230 VAC, full load Typical AC charging input current 25 A at 230 VAC Typical AC charging inrush current 50 A at 230 VAC Peak AC leakage current 4.7 mA at 264 VAC AC utility frequency range 45–65 Hz Typical transfer time 10 ms, inverter ↔ AC bypass AC utility acceptance is ±16% of the selected 200 / 220 / 230 / 240 VAC setting; recovery is within ±13%. The default UPS mode supplies the load directly from available AC utility power while charging the battery. The alternative energy-saving operating mode is described in the manufacturer’s operating-logic instructions. Default three-stage charging starts at constant current, then holds the boost voltage while current decreases, and finally maintains the float voltage. The curve marks the CV-to-float transition at 10% of charging current. Charge-stage indication flashes orange in constant-current/constant-voltage operation and green in float. Adjust charging parameters through MODBus-RTU (RS-485) within the stated range. The supplied battery-temperature sensor supports charging-voltage compensation in three-stage lead-acid charging over 0–40°C. Connect the sensor to the battery using the supplied mating lead and a suitable customer extension: NTC pin 1 is RTH− and pin 2 is RTH+. The charger continues normal operation if the sensor is not used. Battery and Output Protection Low-battery alarm 22 ±0.5 V Low-battery shutdown 19 ±0.5 V Low-battery restart 25 ±0.5 V High-battery alarm 31 ±0.5 V High-battery shutdown 33 ±0.5 V High-battery restart 30 ±0.5 V AC circuit breaker 35 A For reversed DC polarity, the protection is specified as causing no damage; remove the fault and re-power the unit. Typical overload protection shuts down the output at 105–115% for 180 seconds or 115–140% for 10 seconds; re-power the unit after correcting the fault. Apply the model-specific peak-power ratings separately rather than treating these protection thresholds as continuous output ratings. AC output short-circuit protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after the temperature falls. Low-battery shutdown helps prevent excessive battery discharge. Temperature, Input Derating and Environment Operating temperature −30 to +70°C, with derating Operating humidity 20–90% RH, non-condensing Storage temperature and humidity −30 to +70°C; 10–95% RH, non-condensing The horizontal-mounting temperature curve permits 100% load from −30°C through 40°C, then 80% at 50°C, 50% at 60°C and 25% at 70°C. The temperature-controlled fan must have an unobstructed airflow path. The DC-input curve permits 50% load at 19 VDC, 75% at 22 VDC and 100% from 23 through 33 VDC. Apply DC-input and ambient-temperature derating together. Vibration test conditions are 10–500 Hz at 3 G, 10 minutes per cycle, for 60 minutes along each X, Y and Z axis. DIP Settings and Remote Control SW2 selects voltage, frequency and standby saving. S1/S2 OFF/OFF selects 200 VAC; OFF/ON selects 220 VAC; ON/OFF selects 230 VAC; ON/ON selects 240 VAC. S3 ON selects 50 Hz and OFF selects 60 Hz. S4 ON enables saving mode and OFF selects non-saving mode. AC-output remote control uses the PAR1 or PAR2 dry-contact connection between pin 1 (+5V_AUX2) and pin 3 (REMOTE ON/OFF): short for AC output ON, open for AC output OFF. The separate four-pin Power ON/OFF connector controls the whole unit: short pins 1–2 and pins 3–4 for power ON; leave pins 1–4 open for power OFF. Use the supplied switch/connector leads and the manufacturer connection drawing. Parallel and Multi-Phase Systems Built-in active current sharing supports up to six compatible units in parallel. Use short, large-diameter output wiring before the common load connection. For fewer than six units, maximum total output current is rated current per unit × number of units × 95%. Use the manufacturer’s six-unit system instructions for that configuration. Use PAR1/PAR2 to connect the parallel-control bus. For one standalone unit, the parallel connection is unused and PRL is ON. For two units, both PRL switches are ON. For three to six units, the first and last PRL switches are ON and all intermediate PRL switches are OFF. Twist long parallel-control conductors in pairs to reduce noise. For a three-phase, four-wire Y system, use SW1 S1/S2 OFF/OFF for L1 at 0°, OFF/ON for L2 at −120°, and ON/OFF for L3 at +120°. Each line-to-neutral voltage is the selected output voltage, and line-to-line voltage is √3 times that voltage. Follow the manufacturer’s three-phase wiring instructions. Split-phase operation is specified only for the 124 and 148 output versions; it is not a function of this 230 VAC output model. The series headline of up to 30 kW refers to a suitable 5000 W, 5+1-unit configuration. Apply the actual per-unit rating and all parallel/installation limits. Communication and Signal Connections COMM is an isolated MODBus-RTU (RS-485) interface referenced to GND-AUX: pin 1 GND-AUX; pin 2 D+; pin 3 D−; pin 4 +5V_AUX, 4.5–5.5 V relative to pin 1. Use AD1 and AD2 for the communication address according to the user manual. The CRL connector enables 120 Ω communication-bus termination when pins 1 and 3 are shorted. When communication is not required, the catalogue calls for a jumper on pins 2 and 4. PAR1 and PAR2 each use pin 1 +5V_AUX2 (4.5–5.5 V, only for remote ON/OFF), pin 2 GND_AUX2, pin 3 REMOTE ON/OFF, pin 4 SOLAR_ON_OFF for external MPPT-charger control, pin 5 DA, pin 6 SYNC_BUS, pin 7 DB and pin 8 SYNC_BUS2. These isolated signals reference GND_AUX2; the COMM ground reference is separately identified as GND-AUX. The four-pin Power ON/OFF header is HRS DF11-04DP-2DS or equivalent, with HRS DF11-04DS mating housing. PAR1/PAR2 headers are HRS DF11-08DP-2DS or equivalent, with HRS DF11-08DS mating housings. The connector table specifies HRS DF11-**SC or equivalent contacts; select the exact contact variant for the wire and housing being assembled. CMU2E and CMU2E-R are optional monitoring/control units listed for checking inverter status and adjusting output settings. Select the controller and communication arrangement appropriate to this model; they are separate from the standard accessories listed below. Indicators Status LED: steady green means inverter OK; flashing green means system check; steady orange means remote OFF; flashing orange means saving mode; red indicates an abnormal condition. DC Input LED: steady green is 25–31 VDC; steady orange is 22–25 VDC; steady red is below 22 VDC or above 31 VDC. Flashing green indicates maintenance/float charging and flashing orange indicates charging. Load LED is green below 40%, orange at 40–80% and red above 80% load. These colors are steady in inverter mode and flashing in bypass mode. AC Input LED is steady green for utility OK, flashing green for utility error and off when utility is disconnected. Fault patterns: overload or AC short circuit gives steady red Status, DC Input off and flashing red Load. Abnormal DC voltage gives steady red Status, flashing red DC Input and Load off. Overtemperature or fan lock gives steady red Status with both DC Input and Load flashing red. Inverter failure gives flashing red Status with DC Input and Load off.
