I am going to have two multiplus 3000W inverters hooked up in parallel to achieve 6000 effective watts, and am wondering what cable size and fusing I should use for it. I know that for one inverter I would use 2/0 cable along with a 400 amp fuse between the batteries and the inverter. So what would the recommended wire size and fuse size be for my parallel set up?
Additionally, what is the recommended wire routing for this set up. I commonly saw that one positive and negative can be run to the area of the inverters, then jump each inverter via a busbar to power and ground. Is that sufficient or are there other ways to do this?
