^Great piece of trivia or memorabilia but there’s so much out there for solar maintainers compared to whenever VW did that it would imo make sense to use some “new” solar.
So, looking to put in two fresh batteries and make a dual setup. I have a diode isolator. But, I see these Cyrix isolators, and I'm trying to figure out how I could wire in a simple cheap solar trickle charger to keep both batteries topped off, as this won't be a daily driver. Anyone done this?
Considering most of the retailers for the Cyrix also post the installation instructions, I’d just follow those.
If you are installing new, yeah ditch the old diode isolators idea. They still sell em, but why…there has been better technology for quite a while now.
The bigger question is why the isolator? Are you using the batteries as a house/start battery combo or just want the additional battery capacity in general? If the latter then just run batteries in parallel and hook the charger to the most convenient one.
If the former, same thing. Install the isolator/combiner and run the charger to the most convenient one. Same goes for the alternator. Any auto charging relay will work both directions.
I’ve had one on my boat for a lot of years. It’s simple and easy and reliable. (I have a blue sea brand but it’s similar to the Cyrix you posted)
