AC Line W, U over voltage
Generally, the inverter will
reconnect to grid after grid
F41
returns to normal. If this fault
occurs repeatedly then check
as follow:
AC Line W, U low voltage
Generally, the inverter will
reconnect to grid after grid
F42
returns to normal. If this fault
occurs repeatedly then check
as follow:
F43
AC Line V, W over voltage
F44
AC Line V, W low voltage
F45
AC Line U, V over voltage
F46
AC Line U, V low voltage
AC Over frequency
Generally, the inverter will
reconnect to grid after grid
F47
returns to normal. If this fault
occurs repeatedly then check
as follow:
AC lower frequency
Generally, the inverter will
reconnect to grid after grid
F48
returns to normal. If this fault
occurs repeatedly then check
as follow:
F55
DC busbar voltage is too high
1. Measure the actual grid voltage and compare with inverter set
value. if the grid voltage measured is higher than set value, and
then ask help from local electrically company for solution;
2. Check whether voltage protection parameters are appropriate
via LCD or monitoring platform;
3. Check whether the cross-sectional area of AC cable meets the
requirements;
4. If the fault is not caused by foregoing reasons and still exists,
please contact us for help.

1. Check PV input voltage and Ubus voltage via LCD or
monitoring platform;
2. Disconnect DC switch and AC switch, and reconnect DC
switch and AC switch 10min later to restart the inverter;
3. Check whether the inverter works in export control mode. If
so, decreasing PV panel number in series;
4. If the fault still exists,please contact us for help.
