Best Way??
I have 4-Canadian SC6P-220w Panels with the following spec's, Pmax=220W Voc =36.60V ISC =8.09A VMP =29.30V Imp =7.52A Voc-coef =0.1281V/C Noct =45.00C 15A fuse rating/series Per actual meas...

Typical variations include edge effects and temperature changes - try serial and you'll blow the controller.nvreloader wrote:Looks like that controller is good to 150vdc PV input. By far the easiest wiring is 4 panels in series with just 2 small wires to the controller.
Tristar-MPPT-60a,w/ battery temp gage will be mounted.
Is there a better/easier way, to route all these panel wires?
There are controllers that derate for over VOC but don't exceed 150V for the MS MPPT 60 controller.
I recently tested my Canasdiansolar 220w in subfreezing temperatures, The voltage shot to over 40v for a few minutes until the sun warmed the panel. After that it stayed at 37v. It is rated foe 36.6v.
