back up time = 8 x 38 x 12 /600 = 6 Hour (app)

Answer / 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.

do we need NGR panel when the output of the genset is LV but after that it is step up to 22 kv. condition is 12 genset 400v are operating in parallel.
