I have wanted a inverter for a few years ever since I had our Raptor. We dry camp a lot and starting the gen at 7-8am to make coffee and allow the kids to watch movies was getting old lol. This year I pulled the pin and bought a Magnum MS2812 with the Auto Gen start kit and Battery Monitor Kit. I was going to have it installed but not trusting most people I decided to do it myself.
There are a few ways to wire the AC side of it. You can either power the entire AC panel (easiest way) or you can isolate the circuits on the main panel via a sub panel (little more wiring). I chose to power the entire panel as a very smart RV parts guy told me that's how they do all of the installs at his dealership. I decided to try it and if need be could always at a sub panel later if need be.
I read throughout the manuals regarding AC and DC wire size. It can be a little confusing depending on the install type and inverter wiring configuration. Just don't over read into it. I settled on 4/0 wire for all the battery connections. I used a 4g case ground. The AC wire in the transfer switch is 6g so I stuck with it for my install. I ended up doing a dual in dual out configuration. This only required 10g AC wire but I used 6g which is over kill IMO.
The gen start kit is straight forward and our Onan gen had the remote wire running to the switch in the panel so I just tapped into it in the battery compartment. I thought this was going to be the hardest part. I called Magnum just to double check the DIP switch settings and wire config. It was very easy to do. Magnum is awesome to deal with and their support is excellent.
A couple other things. You need to think about how you will mount the inverter. I knew I would mount it sideways but gave no thought to the weight of the unit. I ended up using 1/4 checker plate aluminum bolted to the steel frame behind the storage 1/2" crap board. I would not bolt this type of unit to that board. Also I used a GoPower inverter 4/0 install kit that came with a type T fuse. I also ended up buying another 10ft section of 4/0 which I didn't end up using because once i cut the install kit wire I had enough left over to wire all my batteries. You need a proper crimper if you do this yourself.
I completed the install and have to say I should of done this years ago. This system works excellent and when the batts get low the system fires the gen to charge the batts. I can power almost everything in the trailer at once lol (testing). The remote panel is amazing and you can set all the parameters easily. You can set a quiet time for the gen set as well which is nice for noise sensitive places.
here are a few pictures. If you need help with yours let me know. Cheers
