Solar charging

[Jayco swift camper]

I have a 2024 swift 20t.

The control panel shows the chassis battery is charging from solar but the coach batteries are not.

Do I need to reprogram the type and size of the coach batteries?

If so does anyone have their type?

Thanks!

What is the battery type setting? You most-likely have AGM batteries. Also, check the solar charge controller and verify the batteries are connected to the outputs correctly, as those outputs determine which battery has charging priority.

I just purchased a 2024 Swift 20T. Both battery 1 and battery 2 were set to gel. I changed battery 1 to AGM and battery 2 to flooded. I've searched manual and online and cannot confirm if battery 1 is for the 2 house AGM batteries and battery 2 is for the chassis battery but I think that is how it should be set.

Thanks. I did call the factory and they told me each rig must be searched by the vin via the company cause they but different batteries in along the way. Just say in.

They told me that mine had AGM batts in the #1 slot (chassis) & the #2 slot (house/coach side) all were 115 ah.

I made the changes and parked my Swift out in the sun. Nothing changed. Still not charging the #2 batteries by solar.

It’s going in the shop next week.

Thanks for sharing what worked for you!

This is from the Go Power/Dometic 30A RVC MPPT Solar Controller user manual. This is what my van is equipped with (2023 Entegra Ethos 20D; similar to Swift 20D).
