Building Inverters From Ups/stabilizers. Anyone Know?

please have come across places where people say they can build inverters from ups os is it stabilizers. If anyone knows please help me out i'll like to build one myself(DIY)

you can't simply hook up a big battery to the ups and expect it to work, may be it might work on the first discharge circle then you would have a serious problem of under charged batteries. ups is designed to run for a short period of time. that is why it has a small compact sealed battery inside, and the system is so designed to charge a small battery. in adddition to that the ups might over heat and fry the mosfets or worse destroy the power transformer, so my friend, with just a big battery, that wont work.
however if you are that desperate to convert your ups to power inverter you would have to do a total system upgrade. i am talking about increase mosfet power handling rating for the long duration, cooling systems, increased charging current etc.
sorry i can't get into all that right now, although you can still get a small external battery, say a 60AHR 12volts, sealed or acid, it doesnt matter, the most important thing is that you should have an external battery charger with a matching charging voltage as the ups to boost charging, then you must make sure you run the ups at 50% or half the maximum power capacity.
well thats it, be careful. cheers
