Answer Posted / akshay kumar
UPS BACKUP TIME=CONNECTED LOAD/(BATTERY VOLTAGE*NO. OF
BATTERY)
SUPPOSE CONNECTED LOAD = 1KVA,BATTERY VOLTAGE=12,NO OF
BATTERY=2 THEN
BACKUP TIME =1000(1KVA)/12*2
=1000/24=41.67 AH
(IT MEANS BATTERY DISCHARGE CURRENT =41.67 AH IN ONE HR.)
IF YOUR BATTERY CAPACITY IS 150 AH THEN
BACKUP TIME=150/41.67
=3.35 HRS (APPROX)
