I have 2 off 80W solar panels each connected to their own BlueSolar MPPT 75/10 regulator which are both connected to a 160Ah 12V AGM Battery on my sailboat.
When I leave the boat there is a small parasitic load (size unknown) and I have been adjusting the Absorption and Float voltages to keep the batteries charged.
I have left the absorption time with the default setting and turned the equalisation off. The Absorption voltage is set at 14.6V and the Float voltage is set to 14.4V. Both regulators have the same settings.
When I return after three days the SoC is sitting on 99% not 100%.
Can anyone please advise what Absorption voltage, Float voltage and Absorption time I should use.
