Common Problems and Solutions
Note:
1. The inverter may respond according to the alarms uploaded by the battery.
2. When something might endanger the battery system happens, the battery system will take appropriate
protective measures, such as disconnecting the charge-discharge relays or opening the system switch; if the
battery system automatically opens the system switch, please contact our Technical Support.
(The alarms generated by the battery system can be uploaded to the inverter, or be viewed on the webpage
of battery system.)
