    OK, I think I concede here. My assumption was amperage would be the 'constant', yours was wattage would be the 'constant'. After mulling it over and googling stuff, I think I was wrong and you were right. It just makes more sense that the power (wattage) will be the constant, for lots of reasons. I am sorry.

    Back again my company does not have a fuse in line unfortunately going to their stock inverter and that definitely worries me. Their mechanics are retarded. They should have at least a 250amp fuse 6 inches of the battery bank. I’m pretty electricity inclined but I will admit I don’t understand everything. Anyway here is my thoughts. They are running a 1/0 off the battery straight into the inverter about a 5 foot run. I bought a renology 3000w pure sign wave inverter. That is 250amps for the 12vdc system. The inverter peaks up to 6000w that is 500 amps and that means if I run something that requires a high start like a microwave I’m going to need a 500amp anl fuse, and I don’t want to mess with their crap. My work around and tell me if this will cause problems is to buy another AGM battery for the cab disconnect their inverter and run their 1/0 wire to that. That will place the battery in series with the others and allow me to hook up to it in cab. That will keep the battery charged up. Then, for my build I will need to have 3 feet of 4/0 (0000) aught wire. The 500amp ANL fuse and fuse holder I ordered. I’m going to connect the fuse in line 6 inches into my 3ft positive run. Terminate to the battery in the cab and then to my new inverter. That solved the no fuse issue, and the issue that 1/0 wire accounting for the peak on my inverter is too small. Then I will do another separate run from that battery to their modified sign wave 2000w inverter using 1/0 and a 150amp fuse. Is that electrically sound? My issue is with their existing wire (and the fact they didn’t fuse it) . I don’t want to put that amperage through that wire. That’s asking for a fire. By adding a battery in line using their 1/0 would I be correct in assuming I am no longer putting that draw on that wire? I’ll effectively be just retapping back into the battery bank at a separate point. Can anyone give their thoughts?

    It will not put it in series it will put it in parallel. Voltage will be the same @12vdc into the cab battery.
