I know that a discharged battery can pull down the voltage at the charger. I was trying to measure voltage loss in my converter wiring, switches, etc. The two 105 AH batteries were 12.13v prior to ...

I'm putting 300W of solar on the roof in the coming days. That's really the biggest solution. But for clouds, shade, etc. I still need something I can count on for charging from the Onan genset.

Which would only be powered up and controlled manually. Think of it as a clamp on charger, except it would be hard wired to the batteries.
I see PM3-55's for $110 shipped on ebay. I am leaning that direction.
My alternative would be to buy a PD or IOTA and mount it close to the batteries. It would be a lot better than my present situation.
Both options fit the budget. The tinkerer/optimizer in me likes the separate special purpose charger.
