The 12V power source solar panel
So I came across this on EBay... and they are very local to me... but it sounds like a $100 experiment gone bad. The specs on this thing are waaaaaaay different than any other 12V solar panel that...

30 AH on a winter day in AZ is possible with 150W, if it stays there all day long. Not 2-3 hours.
Yeah, that's the problem with cheap chargers, they don't see the battery voltage after voltage drop.
I don't know why running inverter at supper time should have any effect on solar. "Supper" is usually something that comes later "dinner", meaning around dusk or later :)...
March 8 of last year at Roosevelt Lake, AZ, I got 54 amp-hours from my 100 watt portable, re-aimed several times during the day. 9+ hour time span. It was a clear day, as you could guess. :)
That's outstanding! One day, in Sept in Montana, with my 120 watt panels, after a brutally cold night, and a bright cold blue norther day the next... I saw 60+ amp/hrs out of my 120 watt portable panel. I was running the forced air heater that morning too while the sun was delivering to the solar panel, taking the amps off the top that the panel was generating.
That said, last January in Q, 30 amps out of the panel was about all I was getting with the short days and 120W panel. Hoping the 150 can get me close to 40 amps. I am hoping a poly crystalline panel wakes up a bit sooner.
