Update: The batteries are charging.

They’re charging excruciatingly slow, but they’re charging. Specific gravity 1.09 at 4PM, and there’s bubbles.

Possible problem with the solar panel circuit, maybe. AFAICT the big refrigerator is pulling it down.

    Good news. I was going to write some suggestions but realistically you have one hell of a lot more experience in this area then I do. Good luck, I’m pulling for you.

    Do u have a fridge what type does he have is there a specific size fridge designed for solar that are effecient maybe a rated powersupply like with computers could be wired in to not lose extra current i currently own economy size all small appliances tht are eco friendly and enviromently friendly my fridge is one of those 9 cubic foot cheap ones but i suspect a high qualty 8 or 10 cu foot frisge would be best for solar not to big to hog and not to smal to hog i heard minifridge take as much or more energy than large fridges due to surface area and heat expansion and what not anyway sorry i am a busy guy wall o text ftw just delete this post after reading this message will self destruct in 5 seconds!

    The cheap minifridges that I have tested were horribly inefficient. There are a few Energy Star-rated minis on the market, and they aren’t much better.

    For a random comparison, I Googled a 4 cubic foot Energy Star that take 269 kWh/year But a typical 25 cubic foot 3-door Energy Star kitchen behemoth takes around 550 kWh/year these days. Do the math on a energy/cubic foot basis, and you will see my point.

    Yes, they make super-efficient fridges for solar systems, but they are horribly expensive. These days it might be cheaper to just size a solar power system to power a good consumer-grade fridge.

To the stake with the heretic!
