Hey there-


We just bought a 2019 240URS and I'm really interested in doing some electrical modifications, but would love to find a resource for electrical schematics, if available (or if anyone has done it by hand!)


I did some searching on the forum, but came up short.


Things I'd like to do:  change out the electrical converter to a Victron inverter, and move to lithium batteries as part of modifications for us to live out of the trailer part-time, running laptops and other 120V devices without needing shore power.


I've done the research on the battery capacity and inverter size necessary, but have no gauge on where the wiring runs, or how it's hooked up.  I'd hate to have to start from scratch, but will do so if necessary.  If I do end up doing that, I'll be sure to post the details here.


Love this forum! Hope it stays going!

The converter is at the heart of the 12vdc electrical system and cant just be changed out to an inverter. The converter is used to supply power for the 12v system and to charge the battery when on shore power or a generator. An inverter is used to convert 12v dc to 120v ac for the ac power needs. The converter will either be a part of the power panel or be Located behind it separate from it as it is in our trailer. I didnt believe an electrical schematic exist for the end user. If you remove the screws that hold the electrical distribution panel that houses both the 12vdc fuses and the 120vac breakers you will find that this is where all of the wiring comes together. This is where I found the 12vdc common grounding bar that needed some attention on our trailer. To get some great information on installing an off grid power supply look into post by Oregon camper I believe he has a blog set up just for that.

Good Luck

I doubt you will find the electrical schematics.  As for your lithium battery and converter questions, I would suggest you message Oregon_Camper.  He has vast experience with lithium batteries, the electrical systems and solar charging.
