Solar controller float charge at 13.6
I have an small trailer with 200w of solar panels and two 6v deep cycle lead-acid golf cart batteries. The controller I have is Renogy Wanderer 30A, described as capable of separate bulk, absorption and float charges and apparently is programmed to float at a fixed charge at 13.6v after the batteries are fully charged.
The float is not adjustable on this controller. I note that when in float, the amperage going to the batteries at 13.6v is very low, typically less than 1 amp.
My other trailer has a converter which charges at 13.2v float, which I believe is a sign of a good multistage charging system that does not overcharge the batteries.
Is this solar controller overcharging my batteries in float? Or is the low amperage at 13.6v a safe float?
