INV Inductor CURR
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.

grid harmonics and
no grid-tied condition
1. Wait until the inverter recovers.
2. If the failure persists, please contact the
distributor or after-sales service center.

INV Over TEMP
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
sunlight, if yes, please do appropriate shading;
4. If there are no such problems, and the failure
persists, please contact the distributor or after-
sales service center.
