Inverter-XferSwitcht-ElecPanel

Hi All,
I want to have the capability of running my refer, tv, micro, and outlets as needed off battery on my Mallard M210RB (aka The “Toaster”). I have a Duracell AGM 110AH batt and will add a second. I’m thinking the Inverter and xFer Switch have to be installed in the rear behind the panel (if they fit). In the future, I also want to add 400W solar, so I want to ensure I don’t have to redo the initial install to accommodate the solar. I’m looking for general advice on the plan, recommended components (e.g. 3,000W Inverter?) and specific advice on the wiring. I have a plan on how it needs to be wired. Looking for confirmation that my plan is correct.

Thank you for reading and any advice you can provide.

I did this on my 2017 Newport. I have a generator compartment and transfer switch that controls the source. Shore power is primary, but whichever is on is the power sent to the panel. That way, you can have a small generator to extend battery life.

The point I'm getting to is that the transfer switch is located behind the bulkhead in the main storage compartment and is easy to get to. I have a 3,000-watt dual phase inverter that has a pass through for 50 amps to your panel box. took the wire from the transfer switch that goes to the panel box and connected it to the inverter output. Then, I ran the same size wire from the transfer switch output to the input of the inverter. It was the easiest access, and I put the inverter that is now between the transfer switch and panel box in the "basement" storage (main storage compartment). The wire I took off the transfer switch was plenty long enough to reach the inverter, so I never touched the panel box.

The 6 x 100 AH LI batteries are connected to the inverter. They could run everything for a couple of days with the exception of the two heat pumps and one AC. I could run one heat pump for 4-8 hours, depending upon how hot it was outside. We used the system to power one AC while driving so our cats could ride in the front bedroom (on the bed) and bathroom (cat box) while we traveled. Since all three were ducted together, some of the AC helps keep the rest of the coach cooler.

I plan to add 1200 watts of solar panels before our next big road trip.

Hope that helps.
