The difference between grid 
phase voltages exceeds the 
upper threshold.

If the alarm occurs occasionally, 
the power grid may be abnormal 
temporarily. The SUN2000 
automatically recovers after 
detecting that the power grid 
becomes normal. 

2.

 

If the alarm occurs frequently, 
check whether the grid voltage is 
within the acceptable range. If 
no, contact the local power 
operator. 

3.

 

If the fault persists for a long 
time, check the connection 
between the AC switch and the 
output power cable.
