You are only getting 14a out of that 230w? Pffft, what a wimp. lol
It's too bad you sold those extra panels, it would have been interesting to see a direct 230w PWM vs 230w high voltage/MPPT in various light. I know my poly will hold at least 30v in really low light, so there is something there to convert to amps.
You mentioned temperature and high voltage panels/MPPT. I've run a number of temp/ VOC/SOC/ vs output on the Eco-W with the 220w mono. with panel temperatures as high as 90-120F it always produces 12a in MPPT. The one time I dd it in sub freezing temps the Voc jumped to 40v until the panel started working and producing amps. By the time I got one of the Eco-W's on it the Voc was down to 37-38v and producing a steady 12.75a in MPPT. So I didn't see a loss from heat but do see a boost from extreme cold.
It also means to be wary up bumping your Voc limits by using rated Voc.
