output of inverter after
sudden change or
short current on grid
1. Check whether the external load and the grid
exceed the range specified in the inverter
specifications. After failure recovery, the
inverter automatically recovers to normal
operation.
2. If the alarm is repeated, please contact the
distributor or after-sales service center.

Limit
The output voltage of
the inverter is out of the
range of protection
value.
1. Check whether the external load exceeds
the
range specified in the inverter
specifications. After failure recovery, the
inverter automatically returns to the normal
operation status.
2. If the alarm is repeated, please contact the
distributor or after-sales service center.

INV VOLT DC
Component Over
The DC current
component of the grid
current exceeds the
allowable range.
1. Wait until the inverter recovers.
2. Check the grid voltage or frequency. If the
grid voltage or frequency exceeds the
allowable range of the inverter protection
parameters, report the grid company.
3. If the grid voltage or frequency is within the
allowable range, please contact the distributor
or after-sales service center.

1. Wait until the inverter recovers.
2. If the failure persists, please contact the
distributor or after-sales service center.

The inverter
temperature is higher
than the allowable
upper limit of the
inverter
1. Check whether the temperature of the
radiator displayed on the LCD screen is too
high. If the temperature is too high, wait for a
period of time to recover.
2. Check whether the inverter is at
well-ventilated location.
3. Check whether the inverter is in the direct
