grid-connection conditions are met, the inverter will start operation automatically.
Usually, there are three states during operation:
Indicator lights in Green/Red/Yellow correspondently refer to:
During periods of low radiation, the inverter may continuously start up and shut
down. This is due to insufficient power generated by the PV array.
If this fault occurs often, please call service.
