Cause
1. The inverter is installed
in a place with poor
ventilation.
2. The ambient
temperature exceeds
60℃.
3. A fault occurs in the
internal fan of the
inverter.
1. The PV voltage is too
high.
2. The sampling of the
inverter BUS voltage is
abnormal.
The PV array configuration
is not correct. Too many
PV panels are connected in
series in the PV string.
1. The PV configuration is
not proper.
2. The hardware is
damaged.
1. The PV configuration is
not proper.
2. The hardware is
damaged.
The PV string is connected
reversely.
Solutions
1. Check the ventilation and the ambient
temperature at the installation point.
2. If the ventilation is poor or the
ambient temperature is too high,
improve the ventilation and heat
dissipation.
3. Contact the dealer or after-sales
service if both the ventilation and the
ambient temperature are normal.
Disconnect the AC output switch and
DC input switch, then connect them 5
minutes later. Contact the dealer or the
after-sales service if the problem persists.
Check the serial connection of the PV
array. Make sure that the open circuit
voltage of the PV string is not higher
than the maximum operating voltage of
the inverter.
Disconnect the AC output switch and
DC input switch, then connect them 5
minutes later. Contact the dealer or the
after-sales service if the problem persists.
Disconnect the AC output switch and
DC input switch, then connect them 5
minutes later. Contact the dealer or the
after-sales service if the problem persists.
Check whether the PV1 and PV2 strings
are connected reversely.
