8.1. Troubleshooting

This section describes the potential errors for this product. Please read carefully for
the following tips when doing the troubleshooting:
1) Check the warning message or faulty codes on the inverter information panel
2) If not any error code display on the panel, please check the following lists:
— Is inverter be installed in a clean, dry, ventilated environment?
— Is the DC switch turn off?
— Are the cable cross section area and length meet the requirement?
— Are the input and output connection and wiring in good condition?
— Are the configuration settings correctly for the particular installation?
This section contains the potential errors, resolution steps, and provide users with
troubleshooting methods and tips

GridOVP

The grid voltage is

too high

If the alarm occurs occasionally, the possible

cause is that the electric grid is abnormal

occasionally. Inverter will automatically return to

normal operating status when the electric grid’s

back to normal.

If the alarm occurs frequently, check whether the

grid voltage/frequency is within the acceptable

range. If yes, please check the AC circuit breaker

and AC wiring of the inverter.

If the grid voltage/frequency is NOT within the

acceptable range and AC wiring is correct, but the

alarm occurs repeatedly, contact technical support

to change the grid over-voltage, under-voltage,

over-frequency, under-frequency protection points
