Answer Posted / shivaleela
Ampere Hour=(Watts/DC Voltage)*(1/Inv.Efficiency)*
(1/Batt.Efficiency)*No.of Hours
Ex:W=500W V=12V Inv eff.=0.9 Batt.eff=0.7 Time=1hour
Then Ah=(500/12)*(1/0.9)*(1/0.7)*1
=66.13
It means for 1 hour backup we can use 65Ah Battery for
500W/12V Inverter.
Similarly,for 2 hours Ah=65*2=130Ah

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
