n case of power failure or absence of main voltage these DC-to-AC Electronic Inverters switch to backup mode. The load connected to the Electronic Inverter will remain operative when total load is not more than rated capacity. If the load is more than the rated capacity, Inverter will turn “OFF” and gives beep signals. Then turns “ON” after few seconds for checking the reductions in the load, if not it will “SHUT OFF” again. In case the Load exceeds the Capacity by more than 50% of the rated capacity, the Electronic inverter will remain “OFF”. It will start checking the Load only when it is brought down to the rated capacity or Max. 10% more. In battery mode if the batteries are in charged conditions, the Electronic Inverter will continue to give Output. When the battery voltage drops below the required voltage then the Inverter will display “switch off battery low” & automatically “SHUTS OFF” the output voltage. It will start giving buzzer sound. It is important to “TURN OFF” the Electronic Inverter switch in this condition because batteries would still be drained slowly to support the Buzzer & display. When Mains A.C. is restored, “TURN ON” the Inverter Switch to allow automatic changeover during mains failure.
