And in the interest of full disclosure it’s still not stable at 14.3 but it clearly will be pretty quick. That’s with the ‘pooter left on all morning and a high haze in the sky. With all the advantages, the batteries would have been topped off by or before 10 even though I left everything inside the cabin except the coffee grinder on till bedtime at 9:30*.
Last Autumn when Neighbor S helped me wire up the new/old solar panels he remarked, “Boy, you sure have a lot of power for two little batteries.” It seems that wasn’t an overstatement.
The only argument I have left for NOT running a bigger battery bank is that it would cost too much to replace when it inevitably fails. Which returns me to something several commenters have suggested, and that BB and I were actually kind of arguing about yesterday, which is that maybe I really should run a backup battery bank. It’s the only part of the system lacking total redundancy, and it appears I have the generating power for it. At least on favorable days, I do. And he made the point that I could always shut off the back-up when I needed the generating power elsewhere.
Not going to worry about it right now, the summer will be busy enough without planning big changes to the power system. But it’s something to ponder.
*and a sidebar matter – it’s one thing to be careful about your electrical loads, but I’ve maybe gotten a bit neurotic about it and I really truly don’t need any more neuroses than I already had. I spent the whole evening with the computer on even when I wasn’t using it, every light in the cabin turned on including the four ceiling CFLs I never use, and all damned evening I kept twitching and forcing myself to stay in my chair and NOT get up and turn all that shit off. Practically went to bed early just so I could stop. Yeah, I’m a freak.
