How to know the back up time for a 5KVA UPS which is
connected to 15 nos. of computers? Is there any formula for
this? pls. tell me.

Answer Posted / k.prakashchandra

Back up time is decided by batteries and the load.The
formula is simple. B/U time in hrs = stored energy in
batteries (AH x V(both of each battery) X Number of
batteries)/Load in Watt
