When sunlight is insufficient, the PV inverter may continuously start up and shut down
automatically due to insufficient power generation from the PV panels, which would not lead
to inverter damage.
1. Turn off DC switch first, then take off the AC connector and DC
connector, check PV string voltage. Check if it exceeds the input
voltage in inverter specification.
2. If it does, please reconfigurate PV panel string.
3. If the problem still exists, please call the local service office.
1. Turn off DC switch first, then take off the AC connector and DC
connector
2. Reduce ambient temperature.
3. Move the inverter to a cool place.
4. If the problem still exists, contact local service office for help.
1. Disconnect the DC connector and AC.
2. Reconnect the DC connector.
3. If the problem still exists, please call the local service office.
1. Turn off DC switch, take off DC connector, measure the voltage
of PV array.
2. Plug in DC connector, and turn on DC switch.
3. If PV array voltage is lower than 150V , please check
configuration of invert module.
4. If voltage is higher than 150V and the problem still exists,
please contact local office.
