I am having a battery supported UPS for my computer. Now I am searching for a home UPS/Inverter. Can I charge my UPS by installing an inverter or shall I install home UPS .The back up time for the present UPS of the computer is 20 minutes only. Kindly advise.
More over please clarify.Both UPS and Inverter are drawing power from the mains for charging the battery and the power is consumed for usage during mains are OFF. How can I assure that the battery is fully charged so that I can off the UPS or the inverter in order to save energy?
