No. Fault Cause Solutions
18
Over
Temperature
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.
19 InFan Fail
1. The fan power
supply is
abnormal.
2. Mechanical
exception.
3. The fan is aging
and 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.
20 DC Bus High
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.
21 Gnd I Fail
The input insulation
impedance to the
ground decreases
when the inverter is
operating.
1. Check whether the working environment
of the inverter meets the requirements. For
example, the fault may occur due to high
humidity on rainy days
2. Make sure that the components are properly
grounded and the AC side is properly
grounded.
22 Utility Loss
1. Utility grid power
fails.
2. The AC cable is
disconnected, or
the AC breaker is
o.
1. The alarm is automatically cleared after the
grid power supply is restored.
2. Check whether the AC cable is connected and
the AC breaker is on.
23 AC HCT Fail
The sampling
of the AC HCT 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.
24 Relay Fail
1. The relay is
abnormal or
short-circuited.
2. The control
circuit 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.
