If i have 2kv ups in which 38Amp *8battries hou many hour's
back up i get from 600Watts
Answer Posted / kalpesh m. shah
2 KVA UPS, 8 batteries of 38 AH and 12 V and load 600W. The
back up time = 8 x 38 x 12 /600 = 6 Hour (app)
In single phase output voltage is 230V AC so you can
considerd back up time is = ( 8 Batteries X 38 Ah X 12
Volts / 2.6A Load X 230 V Output )X 60% backup = 3.66 Hour
Successfully working.
In Single phase W = V X I
Watt = 600
Voltage = 230
So, Current is 2.6A.
