I have recently upgraded my PWM Solar Controller 48V 50A to Commander MPPT 48V 60A.I wish to be advised the best array to benefit the most from the 8no. PVs (24V 250W) that I already installed 48V in parallel. Anxiously waiting for response!

can you explain how you 'installed 48v in parallel' with 24v panels? www.renogy.com/template/files/Manuals/CTRL-CMD60.pdfare they 60 cell or 72 cell? page 10 suggests strings of 3 in series (60 cell), 8 is not nicely divided by 3! page 11 list the max power input |

2 24V panels connected in series, then 4 of such connected in parallel. Not sure the number of cells but they are polyfilament panels.

ya can't do 4 in series as that is over max voltage input.
3 in series works but that leaves out 2 panels so what you already have works.
