Here’s the new powershed normal…


I really don’t need those extra two older batteries, which are now bypassing the inverter and running my 12v lighting and bedroom ceiling fan. The plan was to eliminate them and free up some powershed space. But I slept on that decision and decided I like the redundancy. I can lose major chunks of my system and still have a lot of capacity, and planning for disaster is smarter than – not doing so.

Wasn’t going to use all four of the older Trojans for that, though, because I don’t need them and that would be pushing my solar panels’ charging capacity closer to the edge than I want to go.

Somebody suggested that I should swap two of those cables and I agree that would be better. But that short thick cable isn’t flexible enough to fit in that spot. So Monday I’ll buy two more of the skinnier black cables at the auto parts store and that should eliminate that imbalance.

Other than that, I’m done! It still looks like a tangled mess, but that’s only because there’s two of everything. I like redundancy. A lot of it is still second-hand, but year by year my system becomes less improvised.

    Your solar setup and more importantly, your approach to implementing an ever-improving system, are darned inspirational. Going off-grid, at least partially, is looking more and more desirable.

    Took a few seconds to figure out what you are doing in the photo.

    New shiny batts are set series/paralel to give you a pair of 12V battery equivalents at max capacity. Those sure do look nice.

    The older set for 12V DC circuits?

    Looking into the Magnum Energy site, not familiar with their controller. Keep us posted on the Jeep situation.

    Do you have some plan to keep the remaining two Trojans alive “just in case”?”

  4. Joel says:

    Yeah. I’m not convinced it’s worth the bother but since they’re only going to sit around awaiting disposal anyway they may as well do so wired together and connected to my Battery Minder.

    Best way to make the batteries last is to keep the electrolyte level up. While your batteries look easy to get to, a watering system will help. The one sold by Trojan is expensive, but there are some sold for the RV market. (When I was solar, 2 of my batteries were nearly impossible to get to. A watering system was important.)

    Also, you might want to cover the battery terminals with tape. I know you don’t plan on dropping a wrench, but 6-volts are small enough that a decent crescent wrench can bridge the positive to negative terminals. That can be a problem.

    “That can be a problem” That can be an understatement.

    Classmate of mine shorted a 12-volt car battery. It exploded. Insulation is important, Uncle Joel.

To the stake with the heretic!
