Troubleshooting
The inverter has complete protection. When a failure occurs, the inverter will take protective measures. The
general protection is to stop the motor from running and forbid it to restart within a certain period.

Overvoltage
1.
Input voltage is too high
2.
There is large energy feedback
1.Check the voltage of solar
array
2.Check if the DEC time of the
load is too short or the inverter
starts during the rotation of the
motor
Bus low
Undervoltage
1.Input voltage is too low;
2.Illumination intensity is too weak
Check the voltage of solar array
