Model and AC Output Configuration
Series: NTS-3200; Complete ordering model: NTS-3200-212AU; Product type: Off-grid true sine wave DC/AC inverter.
AC output interface: Australian receptacle; Model-code interpretation: 2 selects the 200/220/230/240 VAC output range; 12 identifies the nominal DC input; AU identifies the AC output interface.
This SKU is the Australian receptacle configuration, listed as a by-request option in the catalogue.
Select a lead-acid or lithium-ion battery system compatible with the DC input range and protection thresholds. This inverter supplies isolated off-grid AC loads; a battery charger, battery management system and any grid-transfer equipment are separate system components.

DC Input and Consumption
Nominal DC input voltage
12 VDC
Typical DC input range
10–16.5 VDC

Saving mode is disabled by default. When enabled, the inverter automatically detects an AC output load of 10 W or less and enters saving mode. The DC input-current value describes battery-side input consumption, not an AC output-current rating.

Reverse battery polarity
Internal fuse opens; reverse polarity can damage the unit
Observe the marked DC polarity before connection. Low-voltage shutdown helps limit battery over-discharge; coordinate it with the selected battery system.
DIP Settings and Remote Control
SW1 / SW2: OFF / OFF: 200 VAC; SW1 / SW2: OFF / ON: 220 VAC; SW1 / SW2: ON / OFF: 230 VAC.
SW1 / SW2: ON / ON: 240 VAC; SW3: ON: 50 Hz; OFF: 60 Hz; SW4: ON: saving mode; OFF: non-saving mode.
R.C pins 1 and 2: Open: inverter ON; short: inverter OFF; dry-contact / relay control; Remote port: RJ11, RS-232 communication; RJ11-to-DB9 signal mapping: Rx: RJ11 pin 2 ↔ DB9 pin 3; GND: RJ11 pin 3 ↔ DB9 pin 5; Tx: RJ11 pin 4 ↔ DB9 pin 2.
The RS-232 connection permits a computer or compatible remote controller to read internal data from a single inverter. Use the separately ordered RJ11-RS232 communication cable.
Front-Panel Indication
Status LED: flashing green indicates system check; steady green indicates normal inverter operation; steady orange indicates remote OFF; flashing orange indicates saving mode; red indicates an abnormal condition.
DC input LED for this 12 V model: green at 12.5–15.5 VDC; orange at 11–12.5 VDC; red at <11 or >15.5 VDC. Load LED: green below 40%, orange from 40% to 80%, red above 80% load.
Fault indication combinations: steady-red Status with DC-input LED off and flashing-red Load indicates overload or AC output short circuit; steady-red Status with flashing-red DC-input and Load off indicates abnormal DC voltage; steady-red Status with both DC-input and Load flashing red indicates overtemperature or fan lock; flashing-red Status with the other two LEDs off indicates inverter failure.
Cooling, Environment and Derating
Operating ambient temperature
−25 to +70°C; apply the derating curve
Cooling
Temperature-controlled cooling fans
Operating humidity
20–90% RH, non-condensing
Storage temperature / humidity
−30 to +70°C / 10–95% RH, non-condensing
Vibration
10–500 Hz, 3G; 10 min/cycle; 60 min along each X, Y and Z axis
Horizontal-mounting thermal-derating reference points: -25°C: 100%, 40°C: 100%, 60°C: 50%, 70°C: 25% of continuous rated load. Follow the full curve between the marked points.
DC-input derating: 80% load at 10 VDC, rising to 100% at 11 VDC; the graph retains 100% to 16.5 VDC. Apply this limit together with temperature derating.
Keep the ventilation openings clear. The mechanical drawing shows cooling airflow exiting at the DC-input end.
Mechanical Installation and Weight
Dimensions (L × W × H)
420 × 270 × 98 mm
Enclosure drawing
Case No. 289A; drawing tolerance ±1 mm
Catalogue packing reference per unit
8600 g
This catalogue packing reference per unit is not a measured net weight or a shipping-parcel weight.
The drawing shows a 259 mm body width within the 270 mm overall mounting width. Longitudinal mounting references include 286, 266, 246 mm; follow the mechanical drawing for their exact datums and slot locations.
Connect DC cables to the marked − and + terminals and use the chassis bonding lug as required by the installation instructions. Keep mounting and wiring clear of the fan outlets.
The AU receptacle withstand-current limit is 10 A. When the load current exceeds that limit, the catalogue requires the output terminal connection inside the AC output panel. Do not route the full inverter capability through a receptacle whose current rating is lower. The terminal diagram identifies L, N and FG.
Remote Connections and Accessories
R.C connector reference
JST B-XH or equivalent; printed connector-family reference
R.C mating housing
JST XHP or equivalent; select the matching two-circuit housing
R.C contact reference
JST SXH-001T or equivalent; confirm the complete contact ordering suffix for the wire assembly
Remote controller options
IRC1, IRC2, IRC3; separately ordered monitoring/control units
Communication cable
RJ11-RS232; optional, separately ordered; catalogue quantity: 1
Carry-handle option
Carry Handle; optional, separately ordered
IRC1, IRC2 and IRC3 decode inverter RS-232 data for monitoring and control. Available control functions depend on the connected inverter model; solar, charge and bypass symbols on a controller do not add those power-conversion functions to the inverter.
The Carry Handle accessory list contains one 180 × 27 × 10 mm handle, four foot pads and two mounting screws. Follow its installation drawing; the M4*2 callout accompanies the two screws and does not specify a 2 mm screw length.
Standard DC-terminal protectors are supplied: one red cover, one black cover and four screws. Cover dimensions are marked 52 × 40.8 × 39.8 mm. The assembly drawing marks M3*4 beside the four screws; no separate protector ordering code is given.
Safety, EMC and Reliability
CB IEC 62368-1, DEKRA EN 62368-1, E13, EAC TP TC 004, CE and UKCA are shown for this output configuration. RCM / AS/NZS 62368.1 is additionally shown for the Australian-socket version.
Dielectric withstand: DC input to AC output 3.0 kVAC; AC output to FG 1.5 kVAC.
Radiated emissions: BS EN/EN 55032 (CISPR 32) Class A for this 200–240 VAC output model.
The specification lists BS EN/EN 55024 and EN 55035 immunity, with EN 61000-4-2 ESD at 8 kV air (Level 3) / 4 kV contact (Level 2), EN 61000-4-3 radiated immunity at 3 V/m (Level 2), and EN 61000-4-8 magnetic-field immunity at 1 A/m (Level 1). Final equipment must be checked for system EMC compliance.
MTBF: 336.9k hours minimum, Telcordia TR/SR-332; 30.5k hours minimum, MIL-HDBK-217F at 25°C. Features include MCU digital control, conformal coating and a three-year manufacturer catalogue warranty.
Test Conditions and Typical Applications
Efficiency, AC regulation and THD are measured with a 2400 W linear load at 12.5 / 25 / 50 VDC input for the 12 / 24 / 48 V models respectively. Other unspecified parameters are measured at rated load, 25°C ambient and factory settings.
Typical applications include home and office appliances, power tools, portable equipment, vehicles, yachts, telecommunications and off-grid solar systems with a suitable battery bank. The application drawings use a separate PB, NPB or NPP AC/DC charger where utility or shore charging is required; the inverter itself is not the charger or an automatic bypass unit.
