Or you could design your system this way:
960 W @ 35VDC rated at 27 amps

13.5 Vdc rated at 71 amps
I spent $2000 building my system over a 2.5 year period.
960/130 x 8.2 = 60.55 amps with PWM. If you get 10% more with MPPT (winter temps only) that would be 6a more for 66a. In summer temps get 10% less than PWM for 54 amps. (panels aimed at high sun all cases)
