No. Fault Cause Solutions
27 DC Arc Fault
1. The DC terminal
is not rmly
connected.
2. The DC cable is
broken.
Read the Quick Installation Guide and check
whether the cables are connected properly.
28
AFCI Self-test
Fault
AFCI detection is
abnormal.
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.
29
Cavity
Overtemperature
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. 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.
30 BUS Overvoltage
1. The PV voltage is
too high.
2. The sampling
of the inverter
BUS voltage is
abnormal.
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.
31
PV Input
Overvoltage
The PV array
conguration is
not correct. Too
many PV panels are
connected in series
in the PV string.
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.
32
PV Continuous
Hardware
Overcurrent
1. The PV
conguration is
not proper.
2. The hardware is
damaged.
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.
