Working mode (Optional)

01

AC mains priority

Always use AC mains as priority input to provide AC output and automatically charge the battery,

only stops charging when battery is fully charged, and only starts DC to AC converting untill AC mains is off

02

Energy saving

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≤10.5V during converting, switch to AC mains mode to provide AC output and

automatically start charging the battery (for 24V/48V/96V/192V system, multiply by 2/4/8/16 accordingly)
