Problem Possible Cause
Solution
Overvoltage
1 The grid voltage at the in-
put end of the charger ex-
ceeds 276 V.
2 The grid voltage is still
above 265 V after
overvoltage.
Usually, the charger will be re-
connected to the grid once the
grid returns to normal. If the prob-
lem occurs repeatedly:
1 Measure the actual grid volt-
age, and contact local power
company for solutions if the
grid voltage is above 265 V.
2 Contact Sungrow Customer
Service if the problem
persists.
Undervoltage
1 The grid voltage at the in-
put end of the charger is
below 184 V.
2 The grid voltage is still be-
low 196 V after
undervoltage.
Usually, the charger will be re-
connected to the grid once the
grid returns to normal. If the prob-
lem occurs repeatedly:
1 Measure the actual grid volt-
age, and contact the local
power company for solutions
if the grid voltage is below
196 V.
2 Check if the AC cables are
firmly connected.
