RE: Solar question
Thanks, I was afraid they would buck each other
No such happening. No different than having shore power plugged in with converter charging batteries and solar panel putting power into the battery.
The battery will suck up as much power as it needs and both charging devices will provide power as long as the battery is accepting it. When battery is "full" it's voltage will rise and shut charging devices down to float voltage. One may switch to it's float output sooner than the other due to slight differences in how they read the voltage but when the battery is "hungry" both will peacefully coexist and feed the battery.
Thanks for helping me understand. I've been holding off making any purchase.

RE: Solar question
I did think about just replacing the roof mounted panel with a larger new one, but the existing panel is still producing and I hate to just trash it. It still buys me 1 extra day without using a generator. Thanks for all the input.

RE: Solar question
At 85 solar watts there is no wonder that you are having marginal battery recharging. General rule is one watt per wet battery amp hour. While you can do as you propose, you’d be better off to use matching panels of a larger capacity and one MPPT controller. Remember folding solar panels need to be setup every morning and taken down every evening or they grow legs. Roof mounted panels are usually working before you come outside in the morning.
My roof mounted 85 watt does exactly what it was intended to do. Just changing the way I camp. When it finally dies I will do as you suggest. Until then just looking to extend my stays. Where I stay it is highly unlikely that anything would walk.:)

Solar question
I currently have a 85 watt panel on camper roof, the controller is buried under the counter. Purchased as a kit and now not sure size of controller. It does a fair job of charging our 2 group 29 flooded batteries. I am looking at the folded solar panels with their own controllers to add to system. So my question is can I use both with their own respective controllers?

Except for tunnels, ferries and fueling up ours is always on.

We were there a few years ago and lucky enough that the visitor center was open for tours. We were even allowed right up close to dish, and they ARE very large.
