No. Fault
Grid Rapid
3
Overvoltage
4 Grid Undervoltage
Cause
The grid voltage is
abnormal or the ultra-
high voltage triggers the
fault.
The grid voltage the
allowed range, or the
duration exceeds the
setted value of LVRT
duration.
Solutions
1. If occurs occasionaly, it may
be caused a short term grid
abnormity. The inverter will recover
automatically after the grid is
normal.
2. If it occurs frequently, please check
whether the grid voltage is within
the allowed range.
• If the grid voltage exceeds the
allowed range, please contact
local power operator.
• If the grid voltage is within the
allowable range, please modify
the inverter grid overvoltage
protection value with the
consent of the local power
operator.
3. If it does not restore for a long time,
please check whether the AC side
circuit breaker or output cables are
connected properly.
