Question:
2026 Entegra Accolade XL. Will be storing it indoors with no power hookup. Was wondering if i can use this portable charger to keep the 4 6V AGM house batteries charged while in storage. I can set the panels outside.

Hey Mike, thanks for reaching out. Yes, the etrailer Overlander Portable Solar System # e28VV will do a good job of maintaining the four 6V AGM house batteries in your 2026 Entegra Accolade XL while it's in indoor storage, as long as you can set the panel outside where it gets good sunlight. A 100-watt panel is more than enough to offset the small parasitic loads that remain on the coach and keep the batteries topped off during storage.
Where will you place the panels outside your storage spot?

The Overlander solar setup Jesse recommended has worked out great. We’ve used it on several camping trips to charge our teardrop trailer. It even created some charge on a cloudy day. Setup is easy.
