In case of power failure or the Mains voltage being out of range, the Inverter will switch to backup mode and the the display will show Inverter On, Battery & Load Ok . The Load connected through Inverter will remain operative subject to the condition that Total Load is not more than Rated Capacity.

In case the Load is more than the Rated Capacity, the Inverter will turn OFF and start giving beep signals. It will turn ON after every few seconds (Appx.. 10-15 Sec) and check if the load is reduced within the limits. It will SHUT OFF again if load is still above the Rated Capacity. In case the Load exceeds the Capacity by more than 50% of the rated capacity, the 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 display will show Inverter On
Battery & Load Ok. When the battery voltage drops below required voltage (ie. The batteries are discharged ) 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 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.
