Inverter communication lost
1. Restart the system and check whether the fault has been
cleared.
2. Contact the customer service to remotely update the
inverter EMS and DSP program, after that confirm whether
the fault continues.
3. If the fault can't be cleared, please contact the service
center for further check.
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.
Check whether the input voltage of PV1 and PV2 exceeds 580
V.
If the first one does not exist, restart the inverter to see if the
fault still exists. If it still exists, please call the service center.
1. Check whether PV cable connection is reliable.
2. Check whether PV cable is damaged.
1. Restart inverter and check whether the fault is existing.
1. Check whether the environment around inverter is with
poor heat dissipation.
2. Confirm whether inverter installation meet the installation
requirements.
1. Check whether the PV terminal of the inverter is reversed.
2. If the PV terminal is right, please call the service center.
1. Check whether the PV terminal of the inverter is reversed.
2. If the PV terminal is right, please call the service center.
Check the PV1 voltage. If it exceeds 585 VDC, reduce
the number of PV modules.
Check the PV2 voltage. If it exceeds 585 V, reduce the number
of PV modules
Check whether the actual battery voltage exceeds the battery
charging cut-off voltage by more than 20 V.
Check whether the actual battery voltage is lower than the
battery discharge cut-off voltage.
Confirm that the wiring is normal, and check whether the
battery voltage sampling value is less than 75 V.
