Solar Controller Extremely Hot?

[Gary60]

My solar controller in the bedroom of my 2024 225mls was getting extremely hot and now has a black spot on the screen. I took it loose and found that whoever attached the wires to it was cutting copper strands to slip them into the terminals instead of opening the screws up fully on the terminal. This technique caused high resistance at the terminal and thus caused lots of heat there. Things are better now since I cut and stripped the wires and reinstalled them without cutting the copper strands. I sent an email to Jayco Service but have not heard back yet.

What kind of solar controller? And are you sure Jayco did it? Could it have been the dealership? My unit was "solar ready" and the prior owner installed components (and some of them not well at all).

You don't mention how much panel capacity you have. I'd confirm the solar controller is sized appropriately for the panel wattage and battery(ies) to make sure the system is configured properly.

That sucks. And am I guessing correctly that it is out of warranty?

Mistakes happen, but it sucks when you have to pay for it. Glad you caught it before it caused bigger issues.

That’s a plus. Hopefully they won’t give you any crap about replacing the controller.
