(Bus over voltage)
1. Restart inverter by cycling both AC and DC switches. Wait for
one minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace inverter
Protect0070
(Bus imbalance)
Recommended solutions:
1. Raise limit of IDCmax (for example, 400mA) to allow inverter
more room to adjust in transient condition to cope with imbalance
of impedance and voltage between Grid phases
2. If after adjustment, alarm still occurs, replace inverter
Protect0030
(Inverter Over
Current)
Recommended solutions:
1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace inverter
GridV.OutLim
Recommended solutions:
1. Make sure the grid connection is good.
2. Restart the inverter again.
GridF.OutLim
Recommended solutions:
1. check the AC wires connection and AC frequency is in range;
2. check the measurement value in LCD, if the grid frequency is in
limit, restart the inverter.
Protect0020
(Grid relay error)
Recommended solutions:
1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace inverter
TempOver
(Over-
temperature
protection)
Recommended solutions:
1.Confirm that external ambient temperature is within the
specified range of operating temperature;
2.Check whether air inlet is blocked;
3.Check whether fan is blocked;
4.Check whether the location of installation is appropriate or not;
5.Observe for 30 minutes and see whether the alarm will be
eliminated automatically;
