In the absence of the utility input, the rectifier stops and DC power is supplied by the batteries to the
inverter module. The inverter converts the DC into AC. The static switch connects the inverter
output to the load. At this time, the inverter supplies the load. When power is supplied by the batteries,
the back up time depends on number of batteries and load level.
