Maintenance and Troubleshooting
fault is existing.
1. Check whether the environment around
inverter is with poor heat dissipation.
2. Confirm whether inverter installation
meet the installation requirements.
Restart the inverter and check whether the
fault is existing.
Check the PV1 voltage. If it exceeds
585VDC, reduce the number of PV
modules.
1. Try to reduce the PV power.
2. Restart the inverter to see if the fault
still exists. If it still exists, please call the
service center.
1. Try to lower the ambient temperature.
2. Make sure that the inverter is installed
according to the manual and there is no
shelter around the inverter.
3. After the inverter is powered off and
waiting for 30 minutes, then restart it. If
the fault still exists, please call the service
center.
Check the PV2 voltage. If it exceeds 585V,
reduce the number of PV modules
1. Try to reduce the PV power.
2. Restart the inverter to see if the fault
