Actual bank comprising 20x 55ah agm.
Been coming across lot of articles. posts etc regards actual available capacity depending upon how configured.
Had intended to just go 4 in series then combine the 5 strings in parallel.
Other option thinking 10 in parallel x 2 strings series to produce 2 x 24v banks of 10 then combine those. In this setup running across a lot of differing opinion as how to configure. Two straight end to end of 5 in series or 5 x 2 in series connected parallel.
Basically all configurations make sense for differing reasons am leaning towards cross string grouping as apparently provides better charging balance across the entire bank but will hold my hands up and admit just dont know so many conflicting opinions.
