Loading≤10% automatic shutdown, loading≥11%-100% automatic turn on
03 DC battery priority
Always use DC battery as priority input to provide AC output, for 12V system, when battery≥13V,
starts DC to AC converting; when battery≤84V during converting, switch to AC mains mode to provide AC output and
when battery≤84V during converting, switch to AC mains mode to provide AC output and
