Had to Lower My Solar Float Voltage-Update
Updated 9 July Just a note for folks in a similar situation. My usual procedure in a normal summer here with my set-up with the Eco-Worthy controller (adjustable Absorb and adjustable Float ) is...

I keep everything at float voltage unless charger power disappears. 46 amps discharge and still on float? Hell yes, if the batteries stay filled to the brim.
When batteries are at max specific gravity who gives a fiddler's fantasy if there's a HUNDRED AMP LOAD present? If the voltage at the batteries doesn't sag, KEEP THEM AT FLOAT VOLTAGE. Have the charger top charge them at 5% of entered amp hour rating. Or are these manufacturers too stupid to figure out how to use a shunt to tell when correct amperage is present?
None of the charger folks have talked to a genuine battery design engineer. If they did these nuthouse charger functions would ever hit the market. When a battery depletes beyond the 100% ampere capacity of a charger to maintain float voltage, then and only then should a charger go through a higher voltage charge cycle.
Yes, this means providing a charger with 30, amps, 55 amps, even 100 amperes potential at FLOAT voltage. The charger defaults to three stage charging if the float protocol is interrupted in any way (By overloading, power faults, or disconnection.)
Where DID they get the people who come up with these Laurel & Hardy grade "smart" chargers?
