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 system, multiply by 2/4 accordingly) |
