Useful Solar Data
Next week I'll be dry camping in Q for 3 days and this will be my first "real" solar experience. I've got 3x250W panels and a MPPT60 controller. As a learning experience what data would be useful t...

Clear day in the Phoenix area today. Batteries 100% SOC so loaded them with 100A and recorded 36A output from the controller at 1pm.
3 serial flat mounted 250W poly panels. So I believe I'm on track for 45A+ this summer. Does this seem reasonable?
BTW at the 36A output the MS MPPT 60 adjusted the panels to 5.16A and 86.4V with a controller efficiency of 97%. The panels in series are rated at Imp 8.18 and Vmp 91.74.
750w with PWM should get you 750/130 x 8.2a = 47.3a with panels aimed at high sun. The difference between flat and aimed at high noon is all over the map (literally) In May at 49.3N I got 7.2 flat instead of 8.2 aimed.
So you should get, in May at 49.3N, 47.3 x 7.2/8.2 = 41.5a at high noon.( a bit more with MPPT) Anyplace else, anytime else, could be anything.
