4. UNIT OPERATION

Auto Backup Mode (Factory Default Setting)
The unit is fully automatic. When utility power is available, the unit is running in AC bypass mode.
AC output is supplied from the utility. The internal AC charger is ON and will automatically top up
the battery bank that is connected to the unit. When there is a power failure from the utility or an
AC source is not available, the unit will run on battery power and the unit will generate sinewave
AC output to maintain and operate the load continuously.
