A UPS becomes an inverter when the power fails.

Parts list: UPS of your choice.
Procedure: unplug the UPS.

You're welcome.

Perhaps he wishes to run the UPS off a car battery instead of the intended SLA.
Doubt the charging circuit would work on the car battery, and the UPS would still have the same wattage rating...

convert ups to inverter

true the charger wont be able to handle a car battery bse i need to use 100Ah battery.secondly the oscillator i feel needs to be changed inorder to handle in our case 50HZ since most euipement is 5ohz and lastly the FETS i believe need to be changed.

I have added a big deep-discharge battery to my own UPS and it works great except I need to occasionally top off the battery with an external charger.
