Top Charge Question
Well it's been 33 days since I've seen hookups. The 245 watts of solar gets the Trimetric into the positive AH from full most days. Specific gravity has dropped. A couple of cells to 1250, and a ...

You should see 1.275 or better, for all cells.

That's what USB says. That's where I want to go.
Got involved with chili dogs, conversation and adult beverages last night. Today is advertised as partly cloudy with a high of 72. We haven't seen a totally clear day for about 10 days now. But it looks just a little hazy now at 8AM. So hopefully solar will get me up to near full and the MegaWatt tonight will get one bank on the road to specific gravity happiness.
To answer NinerBikes questions:
Trimetric is a meter, it measures the voltage at the battery as well as net amps into/out of the battery and amp hours from full.
The morning I unplugged, I reset the AH from full to zero and have reset it several times when it got to more than +20 AH. The AH from full was the basics for my top 10% SOC statement. Obviously there is more going on. USB says charge inefficiency can be 5% to 50%. MEX posted a link to a paper that suggested it can be 100% in the top 10% of charge. TriMetric defaults to 5%.
TriMetric
EcoWorthy is set to 14.8/14.4. I have rarely seen 14+ volts but I don't sit inside & watch volts. Mostly I monitor amps which I have seen as high as 11 amps (that's net as measured by the Trimetric).
US Battery recommends 14.4 bulk, 14.4 absorption, 15.3 top charge and 15.3 equalization.
Late breaking news: At 8:22 Mr Sun is putting more into the batteries than is being used.
