3 Stages charging Boost charging, direct charging, float charging
AC over charge protection    Battery voltage ≧256VDC(192V) ≧320VDC(240V) ≧ 480VDC(360V), stop charging after 60s alarm
Working mode (Optional) 1 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
DC battery priority
2 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 system, multiply by 2/4 accordingly)
