Power Max replacement board
I asked Randy at Best converter why the 55 Amp 4-Stage Main Board Replacement did not have a temperature compensation for the board & he said it was not needed because it was a 4 stage charger. When r...

OK so it is a WFCO converter and 30a GP solar controller.
WFCO should drop voltage to 13.2 after a few days of storage. Verify after five days as many fail to drop. Normal 13.6 could be a bit high for float for extended storage in 100+ temperatures. No real harm but watch the water.
GoPower will apply 14.4(wet/AGM) or 14.1(gel) volts for one hour each day before floating at 13.7 volts. This is too much and too high IMO especially for Tucson summers. Again watch the water level.

My recommendation is to upgrade the solar controller to a programmable unit with temperature compensation. Post how many watts the panel is and any plans for expansion for a controller recommendation.
