Default Roadtrek Solar Controller Replacement Programming

The solar controller on my 2018 SS Agile is defective and needs to be replaced. I'm looking for information on how to replace it and how to program it. The dealer said that without Roadtrek support they cannot replace the controller.

Which one is it? The Tracer has generally been trouble free...

Tracer 3125BN. It's dead. Maybe some other component in the system took it out. Voltage at the battery terminals match the battery output. Voltage from the panels is around 22 volts on a sunny winter day up here in Michigan. No lights on the controller on the battery side or the panel side of the controller.

We have heard a lot of stuff about making sure the solar controllers don't see full panel voltages when the controller is reconnected to shut off or just reconnected batteries. I don't ever recall a proven case of that taking out a controller, but it does make some sense and many of us provide ways around that happening in our systems. Could that chain of events have happened to yours somehow?

No I don’t think so. The system was working fine on our maiden trip. The next time we went out for a road trip it wasn’t working.

Is there a fuse for the controller, there should be somewhere, I would think.


You should have 12v at the battery connections of the controller all the time.

The manual for the Tracer is readily available at this website...

Battery side of controller has battery voltage. 13 or so depending on charge. Voltage from panels is about 22 with sun on them.

It certainly does sound dead. With no warranty stuff going on, you could also replace it with any controller of your choice, and not have to try to get Roadtrek settings and such. They alll should wire up the same, and there are some good units out there.

I googled that model and it seems like you can buy it new. Can it be swapped out with a new one?
