Solutions
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 the problem occurs frequently,
check whether the grid frequency is
within the permissible range. If not,
contact the local power company. If
yes, contact the dealer or the after-
sales service.
1. If the problem occurs occasionally, it
may be caused by a cable exception.
The inverter will recover automatically
after the problem is solved.
2. Check whether the impedance
between the PV string and PE is too
low if the problem occurs frequently
or persists.
1. If the problem is caused by an
external fault like a utility grid
exception or frequency exception,
the inverter will recover automatically
after solving the problem.
2. If the problem occurs frequently and
the PV station cannot work properly,
contact the dealer or the after-sales
service.
