In most situations, the inverter requires very little service. However, if inverter is not able to work perfectly,
we recommend the following solutions for quick troubleshooting.
Error display
Possible causes
Corresponding measures
EepromErr
1.Unstable PV input voltage
2.Machine failure
1.After PV input voltage is stabilized, the machine willautomatically
restart.
2. Please contact with local dealer if error remains the same after
several reset.
GFCI.Err
1.PV(+) or PV(-) earthing
2.Machine failure
1.Check PV(+) and PV(-)ground impedance, make sure impedance is
more than 2M
Ω
.
2.Please contact with local dealer if error remains the same after
several reset.
GridF.OutLim
Electricity grid fluctuations
Electricity grid Frequency out of
range
Machine failure
1.
After electricity grid returns to normal,the machine will
automatically restart.
2.Please contact with local dealer if error remains the same after
several reset.
GridV.OutLim
1. Off Phase
2.Electricity grid Phase/line voltage
overload
3.electricity grid Voltage unbalance
1.Disconnect the input/output switch, check the AC-side wiring
and reset the plug to rule out bad contact.
2.
After electricity grid returns to normal, the machine will
automatically restart.
3.Please contact with local dealer if error remains the same after
several reset.
IntFaultA
Machine failure
Please contact with local dealer if error remains the same after
several reset.
IntFaultB
1.PV input voltage is too high
2.Electricity grid abnormal
3.Bus hardware overvoltage fault
1.Adjust the panel configuration to lower the input voltage.
2.After electricity grid returns to normal, the mac
hine will
automatically restart.
3.Please contact with local dealer if error remains the same after
several reset.
IntFaultC
Electricity grid abnormal
Unbalanced current fault
1.After electricity grid returns to normal, the machine will
auto
matically restart.
2.Please contact with local dealer if error remains the same after
several reset.
IntFaultD
1.Electricity grid abnormal
2.Software over current fault
1.After electricity grid returns to normal, the machine will
automatically resta
rt.
2.Please contact with local dealer if error remains the same after
several reset.
IntFaultE
1.Electricity grid abnormal
2.Hardware over current fault
1.After electricity grid returns to normal, the mac
hine will
automatically restart.
