Sir if i have 2kv ups in which 17ah 8 battries load 600watts
how much back up time i get and if i put 6kv ups with the
same no of battries same amp can i get more back up time
please give reply exactly what is the procedure to calculate
back up time for different kv,s

Answer Posted / k.prakashchandra

The KVA of UPS has nothing to do with back up time . The
back up time is = stored energy in watt hour/load in watt.In
this case Back up time = 17 x 8 x 12 (voltage of each
battery)/ 600 =2.72 hour
