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 the local service office for help if the
problem still exists.
Utility Loss
1. Grid is not connected.
2. Check grid connection cables.
3. Check grid usability.
Inverter
fault
PV Over
Voltage
1. Check whether the PV open voltage is higher or too
close to the maximum input voltage.
2. If the problem still exists when the PV voltage is
less than the maximum input voltage, contact the
local service office for help.
Consistent
Failure
1. Disconnect PV (+) or PV (-) from the input and
restart the PV Inverter.
2. If the problem still exists, contact the local service
office for help.
Over
Temperature
1. The internal temperature is higher than the normal
value specified.
2. Reduce the ambient temperature.
3. Move the inverter to a cool place.
4. If the problem still exists, contact the local service
office for help.
Relay-Check
Failure
1. Disconnect all PV (+) or PV (-).
2. Wait for a few seconds.
3. After the LCD switches off, reconnect and check
again.
4. If the message appears again, contact the local
service office for help.
