Solution
1. Check whether Grid is abnormal.
2. Confirm whether the grid cable
connection is normal.
3. Restart inverter and check whether the
fault is existing.
1. Restart inverter and check whether the
fault is existing.
1. Check whether PV cable connection is
reliable.
2. Check whether PV cable is damaged.
1. Restart the inverter to see if the fault stills
exists. If it still exists, please call the service
center.
1. Check whether the environment around
inverter is with poor heat dissipation.
2. Confirm whether inverter installation meet
the installation requirements.
