6. Operation Principles
6.2.3 Battery Mode
The UPS automatically transfers to Battery Mode if the Utility fails. There is no interruption to the load upon failure. In Battery Mode, the
rectifier delivers power from the battery and supplies DC power to the inverter. The inverter filters the DC power and converts it into pure
and stable AC power to power the load.
