Chester,

I used the MS2812. You will also need the ARC control panel, and the BMK (battery monitor kit). That's a 2800 watt inverter. The next model up, the 3000w version, has a lot of extra features to allow you to use the battery bank to supplement the generator. Uh, we don't need that, and it takes a lot of extra wiring.

The ARC remote control mounts exactly in the Xantrex hole. The BMK monitors the current in and out of the battery bank. Unfortunately Magnum requires this kit, while the battery monitoring wires directly to the Xantrex. It's a little bit deceptive when pricing the complete system.

If you go this way, it is easy to use the ARC (remote control) to monitor the State of Charge of your battery bank. It is a much more accurate way of looking at the bank than just voltage.

I bought the system because of the features of the ARC controller and how I could make it play nice with the LiPoFe batteries. If you go this way, I can help with the initial programming. My first read of the manual made my head spin, but it's not as complicated as it looks.
