Adapting / upgrading an existing RV - Sonja Williams

Here is a short list of links of the products we recommend. I will update this page to include Solar when you are ready.

I suggest establishing a coupling with Bus Bars. This will be a central connection for all of your 12v system. You’ll connect the batteries, Inverter, and 12v fuse block to this. (eventually your Solar Charge Controller as well). The 12v Inputs currently run from your Converter to the Fuse block. *Also, it is very important that you run a Ground wire (2awg) from the Negative coupling to the frame of your RV.

Apologies if it’s condescending, but right now your Shore Power runs into your Converter. It should split and run directly into the Breaker box as well. When Complete, Shore will run to The ICS, Then from the ICS directly to the Breaker Box.

The ICS Will go in place of your current Inverter. You will need to splice the 120v line that runs from your current Shore Power Connection to the Breaker Box and remove the connection to the Converter. This ICS is the one we currently use. There is a video on the Amazon page that clearly explains installation. The two wires marked “x” will need to be upgraded to 2awg if the yaren’t already (can’t tell from the image).

Here is a quick link to the Batteries: https://www.redodopower.com/?ref=swjyMSEN

They will also connect to the coupling.

You will want to place a 200a Breaker Between the ICS and the Coupling, as well as a 250a breaker between the batteries and the coupling.

As for the wire, you should wait until you know the exact lengths that you need but here are some links to get you started. You’ll want 2awg from the batteries and the ICS, and I would recommend 4awg from the coupling to the fuse block. Bear in mind that you’ll need to splice these for the breakers so it is more cost-effective to buy bulk wire and connectors if you are comfortable building your own wire.
