HOW MUCH KVA DG SET REQUIRED for charging 12v 4000 ah battery?..

Answer / s.arul

power in DC circuit P = V*I
P = 12*4000
P = 48000 WATTS
so wanted power = 48000 watts
so, required KVA in DG set
KVA = POWER/POWER FACTOR
=48000/0.85
=56470.59 VA
=56.47 KVA
SO,REQUIRED KVA IN DG SET = 57 KVA (APPROX)
