I have an older bus conversion. It has a 24v system for the batteries. I have only the 2 batteries charged by a 350amp alternator for starting the bus, no house battery bank. I have a 3600w/5000m peak inverter that came with the bus, but was not wired up. Can I hook the Inverter directly to the batteries. Wire size and fuse size recommendations would be helpful. I was told the 0 gauge wire with a 350a fuse would be fine, less than 3' of wire being used. No boondocking, the inverter would only be used while on the road to power one ac unit. Once we are at our destination we will plug into shore power. I am setting it up so that I have to physically unplug from the inverter to plug into shore power. One other question, does the dc negative side have to been run back to the battery or can it be ground to the bus chassis. I've worked on high power audio systems and this is a common practice to limit the amount of wire that has to be used. Hopefully I explained what I'm wanting to do properly. Thanks in advance for any advice and help.
