Overland Posted April 27, 2018 Share Posted April 27, 2018 Starting a new thread since the other one seems flaky. This is mostly for Mike since I can't figure out how to send photos via PM. I'll do a big post on my electrical setup someday, after I've redone a few things and added a different hookup for my portable solar. Mike, this is the inverter itself, mounted under the dinette seat by the bath. You have to run pairs of + 12v, at least 1/0 AWG, in and out and also 120v both ways. And a ground strap to the case, so that's 7 large cables plus a coms cable and a temp sensor wire. I ran the 120v along the side and the 12v, ground and and coms through the trough under the dinette. I plan to pull the inverter and screw down a plywood base to secure it better, though it seems fine as it is, screwed into 2 layers of PVC. One thing I do want to do on this end is to install a manual transfer switch for the 120v, in case something ever happens with the charger. [attachment file=IMG_0078.jpg] The inverter has plenty of space for airflow in there. The only time I hear the fan is if I'm really loading it to the max, or if it's really quiet in the trailer when I just plug it in and it's bulk charging the batteries. This is the 12v + side, under the street side bed. Solar comes in at the top right, + goes to the combiner post, then to the cutoff, then though an 80a breaker, then snakes around into the charge controller. + out goes to the combiner post on the lower right, as does the twin + 1/0 from the inverter and the 4/0 + from the batteries, as well as Oliver's cable to their + bus. The bus bar and breaker on the small angled PVC panel are both Oliver's. I moved them a bit to get the post on there but otherwise, I tried not to touch anything on Oliver's side of the electrical. The battery + goes through a cutoff and a 400a fuse first, which are mounted out of sight on this side of the battery box. Solar negative goes around the back of the charge controller onto a combiner post that's hidden, then around the left side and in. Negative out goes down the open space in the hull to the terminal in the next photo. When I redo all of this, I'll add a much larger plywood base, swap the main combiner post for a bus bar, move the battery cutoff and fuse to the board for easier access and generally tie everything down better. Negative connections are kept away from the + on the dinette side of the battery box. Battery - goes into the shunt for the battery monitor, then I have the charge controller coming directly off the shunt and a short 4/0 jumper to a combiner post. Off that goes the twin 1/0 from the inverter, the ground from the inverter, and Oliver's - cable which goes into their distribution box. I removed the charger unit from their box so it's just a fuse and breaker box for me now. I'll redo this in plywood, swap out the combiner post for a bus bar and secure the wiring better. 5 1 Link to comment Share on other sites More sharing options...
