I have been using Poida's MPPT ever since he published it first about 3 1/2 years ago.
This is with my 25KWh Lithium battery bank. There were no problems with the MPPT once I had it set up to run reliably.
My settings are, as per the menu posted back then:
G - zero Iin sensor 123 ADC counts H - zero Iout sensor 119 ADC counts I - max battery Volts 57.5V J - Absorb voltage 56.0V L - maximum Current 50A M - night power 5W
O - NO Equalisation
S - Float voltage 55.5V
The remaining menu letter settings are left as Poida posted them in his message, dated 08 Sep 2020
I have never observed battery bank voltages higher than 56V, the MPPT changes to float once that is reached.
