Camper van radio dilemma

Hi I'm new here, thanks for letting me join. I have an older camper van I've remodeled substantially. I have 200-watt solar power for the usual lights pumps etc. However, I've also installed a new in-dash stereo which I would like to know how I could also hook it up to the solar power so when I'm camped in one spot I can listen to music without draining the van battery. I've searched the internet on how that can be done but can't seem to find anything specific to the topic. Any help would be greatly appreciated.

What kind of "older camper van" is it? Year/make/model and any other specifics will get you better (more helpful) responses than this one.
Consider adding that info to your signature, so it will always be viewable.

What would be best is to wire the power to the radio to the same battery(s) that the solar panels are charging. ~CA

BTW, Welcome to the IRV2 forums website.

Hooking up directly to solar batteries

As suggested, to hook up directly to the solar batteries, removing it completely from the van battery... it would no longer shut off when the key is turned off if I'm correct? Just trying to understand... I have minimal wiring experience and mostly rely on YouTube for my projects!

Yes, that's how it works, depending on how the solar charging system(s) and coach battery bank(s) are set up.
This is all just guess work, having no information on your year/make/model of "older camper van", and any electrical mods that may have already been added to it. If there are any 12VDC hot outlets (I had several in my 2002 Roadtrek) that are wired to the coach battery system, they would work as a solar supported power source for your radio, as well. Assuming the solar charging hardware charges the coach batteries, as would be the more typical setup. No ignition "on" required.

Ah, yes, now I see. Nice rig, good little system.
In that case, my prior post applies to your classic B3500 Ram Conversion Van. Find a way to attach the radio's DC "power in" to the coach batteries, and you're good to go.
It's a good little system (Renogy) to keep things running overnight. The problem with battery banks is not how long they will last powering your "stuff", it's how long it takes to replenish it the next day, either by solar, generator (if installed), alternator/converter/charger.

There are likely two 12v requirements fo your new radio. One for memory and one for main power. You can wire in a DPST switch to switch power sources between the chassis and house batteries

Ok so in this scenario would I wire the main power to the solar batteries but leave the memory on the chassis and install the switch where? Can you expand on the details? Sorry I'm just learning...Thank you.

For the uninitiated, that's a double pole single throw switch. I didn't draw the "wiper" because I figured it was self explanatory.

Have a nice day, ya'll!!!!!
