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.

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.
WiFi commissioning	For the WiFi version, AP mode is activated with DC connected and AC disconnected. If AC was connected accidentally, disconnect AC and DC and wait for the microinverter memory to clear before restarting setup. The eight-digit string under the barcode is the AP number. The English manual identifies the Green Energy app in the App Store or Google Play and refers to MEAN WELL for the Android APK and APP User Guide.
WiFi fault reporting	With sufficient PV DC power, the status LED starts flashing. On a fault, the inverter stops output power; a WiFi-connected system can report a 16-bit alert through Green Energy. The English table maps bits 0–14 respectively to DC overvoltage, DC undervoltage, hardware error, inverter overvoltage, overfrequency, underfrequency, AC RMS overvoltage, AC RMS undervoltage, peak AC overvoltage, AC RMS overcurrent, peak AC overcurrent, overtemperature, ADC error, GFDI fault and relay fault. Use the English table for bit 11; the German table duplicates the peak-current wording there.
A-variant document limits	The manual’s specification table names A variants only and lists a 50/60 Hz grid and 2.412–2.472 GHz WiFi band. It prints IP66/IP67 and rated output in W, while the selected datasheet gives IP67 and output ratings in VA; these source entries are not interchangeable. The manual’s simplified EU declaration names PV-SMI-1000A and PV-SMI-2000A under Directive 2014/53/EU; this is not permission to connect at a particular grid site.
