In normal working conditions, loads get fed from power network, meanwhile batteries are charged with battery chargers. When power network voltage is cut or in out of range, battery mode is activated and inverter gets into the system. While this modulation, there occurs 2-20 ms interruption, which is called transferring time. Battery and inverter couple supply stabilized power until the stored energy finishes or AC grid gets in the tolerances.
