The utility grid
is disconnected.
The utility grid
is disconnected
according to the
safety regulations,
but the grid voltage
is maintained due
to the loads.
1. Check whether the utility grid is
disconnected.
2. Contact the dealer or the after-sales
service.
10
LVRT
Undervoltage
Utility grid
exception. The
duration of
the utility grid
exception exceeds
the set time of
LVRT.
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.
11
HVRT
Overvoltage
Utility grid
exception. The
duration of utility
grid exception
exceeds the set
time of HVRT.
12
Abnormal GFCI
30mA
The input insulation
impedance
becomes low when
the inverter is
working.
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.
13
Abnormal GFCI
60mA
14
Abnormal GFCI
150mA
15 Abnormal GFCI
16
Large DC of AC
current L1
The DC component
of the output
current exceeds
the safety range or
default range.
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.
