Can it be done safely without big problems?
327-watt solar panels with 64.9 VOC and 6.46 amps ISC.
can I put 2 in series = 129.8 volts @ 6.46 amps ISC,
then put 3 sets of 2 panels (wired in series) in parallel = 129.8 volts @ 19.38 amps ISC,
then put 2 of those 6-panel arrays in parallel again = 129.8 volts @ 38.76 amps ISC?
the outback flexmax 80 solar charge controller is up to 150 volts DC input not to exceed 64 amps input as I read it and rated at 80 amps output (48 volt battery, the pv array input limit is 4000 watt from the pv array)
every 6-panel array is 1962 watts (or 3924 watts for 12 panels).
2 panels in series; (volts (64.9+64.9)adds up to 129.8 volts, while the amps remains the same @6.46 amps)
3 sets of 2 in series wired in parallel; = array of 6 (volts stay the same @ 129.8 volts, while the amps add up 6.46+6.46+6.46 now equals 19.38 amps)
then 2 arrays of 6 panels each wired in parallel for one larger array of 12 panels. volts stay the same @129.8 volts but the amps add up 19.38+19.38 now equals 39.76 amps)
what do you think?
I have 2 of the 80 amp outback flex max charge controllers and 40 panels. or am I stuck with only 8 panels per charge controller?
