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.
Non-Backup Mode
Same as Auto Backup Mode but when there is a power failure of the utility or the AC input source
is not available, the inverter will not turn ON automatically. You are required to manually turn ON
the inverter.
