Photovoltaic Solar Inverter Series ES
Status Diagnosis and Troubleshooting
Inverter Voltage
unbalance
The waveform of the
voltage of the
photovoltaic solar
inverter is outside the
tolerance.
27. Shut down the photovoltaic
solar inverter (disconnect
PV generator from the
feed).
28. Restart the photovoltaic
solar inverter (plug the PV
generator into the feed).
29. If the error occurs again,
please contact your dealer.
The fault current of the
grounding wire is too
high.
30. Disconnect the PV
generator from the feed
and check the peripheral
AC system.
31. When the problem is
resolved, reconnect the
PV. Check the status of
the photovoltaic solar
inverter.
32. If the error occurs again,
please contact your dealer.
The insulation
between the PV
connections and the
earth is less than
1 MΩ.
33. Disconnect all PV (+)- or
PV (-) connections.
34. Check the impedance
between PV (+), PV (-)
and the ground (must be
more than 2 MΩ).
35. If the error occurs again,
please contact your dealer.
