Hi
I installed 12- 235watt panels on my system. I use an outback 60 amp charge controller. I got between 38 to 48amps charge on my 48 volts 8 battery bank onb good sun in the 11 am to 2 pm hours. I have 12 panel wired in 4 panel in each series with 3 series. the two series with one pair wire gave me about 26 to 33 amps and the one series with one pair wire give me 13 to 18 amps.
I purchase 8 more panels which is rated 250watt max. I also boungt one more 60 amps outback charge controller as one will not manage all the panels. how ever when I installed the new panel in two series of 4 each and conbine them to one pair charge wire, I only get between 15 to 20amps while the old 12 panels gave me 40 to 45 amps. when I disconnect the single series and the old 8 panel gave me ~30 amps and the new 8 panels only gave me ~17amps. what could be wrong?
Thanks .
