Balancing:
[Periodical maintenance] The battery system will become unbalanced if it has not been
charged fully for a long time. Solution: Perform balancing maintenance (fully charge)
every 3 month. Generally this maintenance progress needs to be completed when external
devices such as the monitoring software and battery and inverter have proper
communication.
Output relay check:
[Periodical maintenance] Under low load (low current), check the output relay OFF and ON
condition; listen if the relay clicks, which means that it switches off and on normally.
