Are Home UPS and invertor two different things? Or is it that the UPS envelopes inverter as well?
Home UPS is usually meant for computers and/or small devices. They have a built in battery from which the derive power in case of a failure in mains.
the inverter on the other hand is just the DC-AC coverter. It relies on an external battery bank to draw power at times of failure.
Inverters in combinatio with batteries can power more appliances than a small UPS.
I bought the usha UPS around 18 months back. It stopped working 6 months back ..
Still in warranty period.. The supprt from USHA is very poor ..
They do not track the reported problems properly .
If you want to buy inverter , do not buy usha inverter .. FYI: my inverter is still not working , and usha management never cares to solve my problem
Mr. Armstrong,
Where are you from and where did you buy the UPS from? If you could also give us some additional details like cost, it would be useful for our readers.
I would like to thank you for the detailed feedback that you have posted on the site.
