MPPT tracking efficiency	>99.5% in the specification table; the series feature summary states tracking efficiency up to 99.9%.
CEC weighted efficiency	CEC weighted average efficiency up to 96.5%, as stated in the series features.
Night power consumption	110 mW.
Working temperature	−40 to +65°C.
Working humidity	0–100%, as listed in the working-humidity specification.
Enclosure protection	The series feature summary states IP67; this model's specification-table entry is NEMA 6. Use the model-specific enclosure designation for selection.
Protection and warning features	Ground-fault detection and interruption (GFDI) and surge protection are listed. Automatic high-temperature and fault warnings support operation monitoring.
Manufacturer warranty	25 years for this B-type model.

Communication and status indication

Communication	PLC.
App and web monitoring	Green Energy APP and web monitoring provide real-time generation data and equipment status, with fault alarm and localization functions. The model-specific communication method and applicable network or gateway are required.
Monitoring interface functions	Power-station selection, current station power, generation totals, network condition, generation curves and statistics, energy/financial benefit displays and environmental-benefit displays, device list, power-plant management and device management. Benefit figures shown in the app are illustrative, not a guaranteed energy yield or financial return.
App access	The datasheet provides Green Energy APP download QR codes for iOS and Android.
LED-table applicability	The catalog indicator table describes WiFi-connected and WiFi-not-connected states. This model is specified for PLC; confirm the supplied indicator scheme before applying the catalog WiFi-state meanings. The table does not establish WiFi hardware as standard on this PLC model.
Green indicator reference	Flashing once per 1 second: WiFi connected and AC connected; once per 2 seconds: WiFi connected and inverter standby; once per 4 seconds: WiFi connected and inverter working.
Red indicator reference	In the July 10, 2025 catalog table: flashing once per 1 second: WiFi connected and AC disconnected; once per 2 seconds or once per 4 seconds: inverter alert. See Indicator source differences below before interpreting the WiFi state.
Orange indicator reference	Flashing once per 1 second: WiFi not connected and AC connected; once per 2 seconds: WiFi not connected and inverter standby; once per 4 seconds: WiFi not connected and inverter working.

Mechanical layout and accessories

Dimensions	268 × 250 × 46.5 mm; drawing tolerance ±1 mm.
Device weight	3.4 kg, catalog WEIGHT value for the inverter.
DC connector designation	The specification table identifies QC4, while the feature list uses MC4 plug-and-play wording. Confirm the supplied connector and matching mating parts before connection; these names do not establish interchangeability.
Connection layout	Drawing labels: 1 = DC input 1 (+); 2 = DC input 1 (−); 3 = DC input 2 (+); 4 = DC input 2 (−); 5 = AC output terminal; 6 = optional WiFi dongle; 7 = LED display.
Optional dongle location	The mechanical drawing identifies a WiFi dongle as optional; confirm the supplied communication configuration rather than assuming an optional dongle is included.
Standard installation accessory	The accessory list shows an installation tool as a standard accessory.
Optional accessories	Ordered separately: PV-AC BUS-C, AC output cable with Euro plug and customizable plug option; PV-AC BUS-T, Type T output bus; PV-SMG-001, PLC communication monitoring gateway; PV-SMNZ, anti-backcurrent meter.
System connection examples	The rooftop diagram shows PV inputs connected to each inverter and AC trunk cable, tail cable and end cap leading to the grid. It illustrates WiFi monitoring; the pictured unit count is not a maximum branch rating. A separate balcony PV connection example is also shown.

Safety, EMC and applications

Safety standards	EN 62109-1:2010 and EN 62109-2:2011, approved as stated in the specification table.
Certification-mark scope	Intertek ETL Listed mark with c/us designation (cETLus), control number 5031216, is shown for B/C types only.
Withstand voltage	Input–output: 4 kV DC; input–FG: 0.8 kV DC; output–FG: 4 kV DC.

Installation and operating guidance

Electrical installation safety	Do not connect the inverter to the utility grid or energize the AC circuit until all installation procedures are complete. Installation involves electric-shock hazards: when a ground fault is indicated, conductors that are normally grounded may be ungrounded and energized.
Mounting and cable preparation	Secure the PV modules to the racking and mount the microinverter on the racking or PV-module frame. Check that the unit is intact and no components are missing. Prepare the correct end-cable type and length; contact the distributor for an exchange if the supplied cable is unsuitable.
PV channel connection	Connect each PV module to its corresponding pair of DC sockets. The manual identifies MC4/QC4 terminals; use the actual matching connectors and polarity of the supplied unit. Keep each channel paired according to its connector diagram.
AC topology and grounding	The trunk-cable diagram shows a grounded rack and protective-earth connection. Follow the supplied cable and system topology. The manual’s balcony example uses customized AC terminals that differ from standard products and contains one inverter; this example does not define a maximum inverter count for a trunk-cable system.
Surge protection and warranty limitation	Built-in surge protection can be exceeded by a sufficiently energetic surge. The manual recommends external surge protection as part of the solar installation, installed according to the surge-protection device manufacturer’s instructions. Lightning damage is excluded from the limited warranty described in that manual.
Indicator source differences	For the red one-second indication, the datasheet says WiFi connected with AC disconnected, whereas the user manual says WiFi not connected with AC disconnected. The third indicator appears orange in the datasheet and yellow in the manual. Confirm the indication for the supplied revision. WiFi labels in these charts do not establish WiFi hardware on PLC variants.
