4. Excessively high
PV voltage
PV voltage exceeds
the specified value
1. The PV voltage is
too high;
2. The inverter has
internal faults;
1. Observe for 30
minutes to see
whether the alarm
will be eliminated
automatically;
2. Check whether the
PV voltage
exceeds the
specified range;
3. Switch off the PV
input switch, and
then switch on the
PV input switch
again after 5
minutes;
4. Contact our
after-sales service
center.
5. PV input reverse
connection
PV panel is
connected reversely
1. The positive
electrode and
negative electrode
of PV are
connected
reversely;
2. The inverter has
internal faults
1. Check whether the
positive electrode
and negative
electrode of PV are
connected
reversely;
2. Contact our
after-sales service
center
6. Excessively low
insulation
resistance
The insulation
resistance of the
positive-to-ground or
negative-to-ground
of PV exceeds
specified range
1. Air humidity is too
high
2. Insulation
resistance is
reduced by other
external factors;
1. Observe for 10
minutes to see
whether the alarm
will be eliminated
automatically;
2. Check the PV
system for
insulation;
3. Contact our
