Utility Loss
1.Grid is not connected.
2.Check grid connection cables.
3.Check grid usability.
Fac Failure
1. The PV Inverter will automatically restart within 5 minutes if the grid returns to
normal.
2. Make sure grid frequency is in conformity with the specification.
3. Contact local service office for help if the problem still exists.
Inverter
failure
1. Check whether the PV open voltage is higher or too close to the maximum input
voltage.
2. If the problem still exists when PV voltage is less than the maximum input voltage,
contact local service office for help.
1. The internal temperature is higher than normal value specified.
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.Turn
off DC switch of the inverter.
2.Wait

Ground I Failure
1. The ground current is too high.
2. Unplug the inputs from the PV generator and check the peripheral AC system.
3. When the problem is cleared, reconnect the PV panel and check the Inverter status.
4. Contact local service office for help if the problem still exists.
Vac Failure
1. The PV Inverter will automatically restart within 5 minutes if the grid returns to
normal.
2. Make sure grid voltage is in conformity with the specification.
