I'm in the process of installing a Renogy 500A Battery Monitor in my 2201TL. The monitor arrived today and I've planned out a spot to place it.

The monitor screen is about 4" x 2.5", and I'm planning on installing it near the existing Micro Monitor and Telephone/Cable plate on the side of the refrigerator cabinet. I will be able to fish the thin 25' shielded cable down and along the wiring along the floor into the front cabinet, then down through the floor and into the battery compartment where the shunt will live.

The meter displays the charge and discharge rate in amps, as well as remaining amp-hours, real-time wattage, and you can program a low and high-voltage cutoff as well.

After this install, I'm planning on adding a couple 100W solar panels to the roof, a charge controller, and hard-wiring a small inverter in.

I'll post some pictures here when I start on the work
