Was it 136 AH in or out of the battery? I don't remember, your panel is about 200W?

Loads don't change the panel output. Your peak current was 21A, so 25A controller didn't cut anything off on this day. Just to make sure I've got it right - total 136 AH output from flat 500W panel?

correct
1875.2 Watt Hrs
136 amphrs
I'm at the Louisville Ky Good Sam Rally, and i've been plugged into shore power for several days
the converter is basically in float mode
and the batteries are sustaining a fairly high charge level
they were NOT low from overnight use
the solar only needed to supply the days consumption, NOT recharge the battery bank of eight batteries 960 ampHrs
i don't get multiple days of shore power very often, we normally dry camp
just before sundown i plugged in my vector 40 amp charger set on AGM, and zap them, then i'll change it to desulfate and let run until we break camp

That's awesome, Wiz!
Shore power, eh? Sounds like a good opportunity to do some battery conditioning.

I thought 500W panel would collect a bit more AH. Around 160-170 AH. Though... If it was hot, and panels not cleaned for a while, and are 7 or 8 years old - this could explain 136 AH.
