Inverter installation

my truck has four 1,150 cca battiers that's 4,600 cca
i run 2X 1,500 inverters. 1 for the fridge and mirco and 1 for everything else
1 set if wires for each inverter. each set has 2 50 amp inline fuses

 

I don't think the math works that way. If I'm not mistaken those batteries are hooked up in parallel not series. I think you will find your battery will only deliver 1150 cca but will do it longer then if it was just one. Also those 50 amp fuses limit you to 600 watts before one blows.

 

Yes, you are correct.

 

Get your cable from an auto parts place, I bought 25 feet of 4 gauge for 40 something dollars, the insulation on jumper cables usually isn't the same and may not made for constant duty. Put your fuses as close to the batteries as possible, use wire loom on your wires and rubber bushings anytime you pass through any metal.

 

Make sure the wires have a good flexible rubber casing. I have used welding cables on many trucks and no problems so far
