Trailer aux power question

[BaileyBoyz]

My travel trailer has solar panels on the roof that continuously charge my batteries and power the camper equipment. When towing that is connected to the Ram 12v power. I suspect it is causing issues with trucks computer. My traction control light came on, etc. while towing but no issues when the trailer is not hooked up. What do you think? Also there is a solar disconnect installed by the manufacturer next to the inverter.

Install the appropriate diode or isolation solenoid on the trailer. Diode will allow power from the truck to the camper, but not the reverse. Isolation solenoid would be wired to disconnect the solar when it senses voltage from the truck.

<edit> I missed your last line that says there is a solar disconnect. That should be disconnected whenever you trailer. That alleviates the need for the above I mentioned.

Yeah any time you aren't using the solar, that should really be disconnected. It'll prevent backfeeding issues.

Thanks, that is what I figured. The dealer really should mention that to customers with the solar set up.

Funny thing was the sales guy at the dealer said he did not know why they would put a solar disconnect on trailer.

U need to allow the well known lost art of Common Sense to prevail. Most Sales People just have a job, and have no idea about how anything that they sell works. I cannot say how many times I have gone into a place to purchase something, and asked questions, and the "sales person" just dumbfounded, had no clue and just made chit up.

EXAMPLE: I was at the Chevy house Dec 22 looking at a 23 Sierra. The sales guy kept pushing trying to get me to Buy this truck, and kept pushing all these great options like: Hey, look at this fancy tailgate, great stuff huh. When asked about the 5.3L Ecotech problems with lifter issues and such, all he could do was deflect, opened the back door of the truck and started harping on the great under seat storage. Was just too funny, I just let the fool keep up his BS, and of course walked away. I just wanted to look at the pretty truck, hee hee.

Of course, either wire in an isolator like Chopper said, or hit the disconnect switch on the panels. RAMS are STUPID Finicky about power issues, and back feeding into the electrics on yer RAM gonna cause U grief, just saying.

Yeah as said above, sales people don't always know what they're selling. You'll find a few that actually take the time to go through the literature and learn what they're talking about and how accessories work, but not many.

I could never sell cars or RVs. I know too much about them and enjoy keeping up on how things are built and what issues they have and ways to fix them. I would likely be constantly upsetting people because 'no your half ton truck cannot pull this 43 ft toy hauler,' 'no you can't put a 35 ft travel trailer behind your Honda Accord,' 'I'm sorry your car dealer told you this could pull that much weight, it's a made up number and here's the numbers you really need to go by.'

Could be possible he was selling turnips the week before.

@BaileyBoyz Did disconnecting the solar charger fix your problem? I have a 2020 Ecodiesel, sounds like you do also. We just purchased a new travel trailer and are experiencing similar issues. our previous trailer did not have solar and experienced no towing issues over probably 30k miles of towing. The dealer is baffled.

If you are having problems, did you disconnect your solar panels to see it corrected your problem?

Working on it. Trailer is at the dealer right now so I don’t have access to it. Will report back when I have some useful info. Was hoping that BaileyBoyz might be just hanging around.
