January 21, 2010, a Thursday
Abiquiu Lake, New Mexico, USA
— Snowy day
It was dull and gray out when I got out of bed around 7:05. I had breakfast, and the Townsend's solitaire was still attacking the RV. J and I talked about our travel plans for the next couple of months, and it looks like we'll be able to squeeze in everything we want to do. :) We turned on the generator around 9:40 for an hour, and I did some computer work.

I had lunch around 11:55, and it was still dull and gray outside. We turned on the generator at 12:15 for an hour and a half and I did some computer work. J went outside around 2:15 to photograph the Townsend's solitaire. She came back in around 3:50.

We had dinner at 6:40 of frozen King Soopers (Kroger) pepperoni pizza that J kicked up a notch by adding some fresh, multi-colored, bell pepper slices. No, we didn't eat the pizza when it was frozen. :) It was tasty, but not as good as the Kraft or WalMart pizzas we've had.

We turned on the generator at 7:20 then watched an episode of Desperate Housewives on DVD. I did some computer work. Around 9:00, I discovered that our Inteli-Power PD9160A power converter (converts 110VAC to 12VDC) wasn't putting much power into the batteries — only about 12A instead of the usual 25-35A when the batteries are just below half charge. So, I turned off the power converter, unplugged the Charge Wizard, then turned the power converter back on. Now we were getting about 22A into the batteries. Not great, but much better than we had been getting. I did some more computer work, then turned off the generator at 10:00, the end of the generator hours. We didn't get nearly as much charging done this evening as I had hoped — we only went from -237Ah to -193Ah. Our four AGM batteries give us 400Ah of capacity, and we don't like to run them down much more than 50% (-200Ah), but they take a charge faster when they're not full, so keeping them around 50% full when maintaining them with the generator makes sense to me.

Wouldnt your coach engine charge faster? I know ours does. I rarely charge the batts from the generator.

The coach engine probably does charge the batteries faster if you're driving down the road, but our coach engine wouldn't do much if it was just idling. With the generator, in addition to putting 25-35A into the batteries, it's also providing 110VAC that we can use "for free" to run our computers and such.
