Fault
Cause
Solutions/measures to address the
issue
1
Utility Loss/
F01:Grid outage
1. Utility grid power
fails.
2. The AC cable is
disconnected, or
the AC breaker is
off.
1. The alarm is automatically cleared
after the grid power supply is
restored.
2. Check whether the AC cable is
connected and the AC breaker is on.
2
Grid Overvoltage/
F02:Grid overvoltage
protection
The grid voltage
exceeds the
permissible range, or
the duration of high
voltage exceeds the
requirement of HVRT.
1. If the problem occurs occasionally, the
utility grid may be abnormal
temporarily. The inverter will recover
automatically after detecting that the
utility grid is normal.
2. If it occurs frequently, please check if
the grid voltage is within the
allowable range.
 Contact the local power company
if the grid voltage exceeds the
permissible range.
 Modify the overvoltage protection
threshold, HVRT or disable the
overvoltage protection function
after obtaining the consent of the
local power company if the grid
frequency is within the permissible
range.
3. Check whether the AC breaker and the
output cables are connected securely
and correctly if the problem persists.
3
Grid Undervoltage/
F03:Grid
The grid voltage is
lower than the
permissible range, or
1. If the problem occurs occasionally, the
utility grid may be abnormal
