Low Insulation
Res.
1. The PV string is
short-circuited
to PE.
2. The PV system
is in a moist
environment
and the cable
is not well
insulated to the
ground.
1. Check whether the resistance of the PV
string to PE exceeds 50kΩ. If no, check the
short circuit point.
2. Check whether the PE cable is connected
correctly.
3. If the resistance is lower than default
on rainy days, please reset the ISO via
SolarGo app.
Inverters for the Australian and New Zealand
markets can also be alerted in the following ways in
the event of insulation impedance failure:
1. The inverter is equipped with the buzzer: the
buzzer sounds continuously for 1 minute in case
of failure; If the fault is not resolved, the buzzer
sounds every 30 minutes.
2. Add the inverter to the monitoring platform, and
set the alarm reminder, the alarm information
can be sent to the customer by emails.
19
Abnormal
Ground
1. The PE cable of
the inverter is
not connected
well.
2. The L cable
and N cable
are connected
reversely when
output of the
PV string is
grounded.
1. Check whether the PE cable of the inverter
is connected properly.
2. Check whether the L cable and N cable
are connected reversely if output of the PV
string is grounded.

Anti Reverse
power Failure
Abnormal
uctuation of load
1. If the exception is caused by an
external fault, 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.
