acceptance charging rate AGM batteries
Hi all, It is generally thought that acceptance rate for a flooded deep cycle battery is about 12.5 amps per 100 amp-hours of capacity once the bank is at 85% state of charge. I know that accept...

Well, well, well,
A little surprize thanks to the good folks at Magnum.
I was crowing about how well the solar system had topped off the battery bank.
It turns out that the Magnum is some what sensitive as to input voltage.
My Yamaha cranks out 122 volts under low loads. With the Fridge that dropped to 121.x. Sooooooo, the charging rate on the Magnum goes DOWN as the input voltage goes UP. This happens in load support mode and also when it is in "regular" pass through mode.
When I turned on the George Foreman grill I wanted to see what would happen. Well, something sure did. Charging amps jumped from a measly 12 amps up to 40.
Talk about a conundrum, LOL. I spend 16 years trying to solve low voltage. I finally have it "beat" with the autoformer. Now I have--too much voltage to do fast heavy duty charging--at least when the batteries are not horribly low.
