Need some help determining correct wire and fuse sizes for a vehicle that will have 2 100ah LiFePO4 batteries wired in parallel and a 1500 watt inverter.
I think I have the math correct for the inverter. Please correct if I am wrong.
1500 watt inverter assuming 90% efficiency
1500/.9=138.8 amp.
Inverter fuse size.
138.8 amp x 1.25 = 173.5 amp minimum amp fuse. I could use a 175 amp fuse that is very close to the minimum size, should I round up to 200 amp?
Inverter wire size.
2AWG
Battery cables,
I know I need some help here. Since there are two100ah batteries in parallel I can pull 200 amps I am not sure how the wire and fusing is determined and will I need to have a fuse for each battery?
