PWM vs MPPT Test Results
Today (blue sky, not quite to STC at this date at this latitude 49.3N but almost according to the calculator on that) I was able to run a test on my 230w panel and Eco-Worthy 20a MPPT controller. ...

Hi BFL13,
Converted to percentage
9.200/10.07 ~= 8.7 % more
11.85/12.74 ~= 8.7 % more
13.44/15.32 ~= 12.2 % more
14.50/16.65 ~= 12.2 % moreBFL13 wrote:
I could at last compare the amps I got with an equivalent 230w on PWM. Result was a slight MPPT advantage in amps. EG 9.2/10.07, 11.85/12.74, 13.44/15.32, and 14.50/16.65 going from am-high noon.
I think the % increase is even higher than you show. Here is my calculation. I think you divided by the MPPT A not PWM amp.
for case one 9.2A
Increase % is 10.07-9.2=0.87A 0.87/9.2= 9.4%
11.85/12.74= 7.5%
13.44/15.32 =14%
14.5/16.65 = 15.1%
Noticeable % increase.
