In case the utility power fail, the AC-DC converter and charger will be off duty. The
DC-DC converter works and converts the battery voltage into DC-BUS voltage. The
DC-AC inverter converts the DC-BUS voltage into AC voltage. This is so called
“ON-BATTERY mode”.
The auxiliary power circuit supplies the designated power to all the control circuits.
Because the DC-AC inverter is always working, the DC-DC converter can work
rapidly and replace the AC-DC converter while the utility power fails. Furthermore,
the bypass relay continuously keeps in the position of inverter output to supply the
regulated power for the load. There is no power failure to loading equipment.
