Derating 24v Solar Panels?
I'm considering running two 250w/24v poly panels; tracked/pointed during spring/fall, and flat during the summer; thru the Tracer 3215BN 30a mppt controller. I can also get 200w/24v mono panels, local...

i ran MPPT untill, i got a burned up terminal in Jan
then i remove the blue sky 2000e, and installed the Xantrex C40 PWM spare
which is what i am currently using
i have been shopping for another controller to be my spare
I did buy a JoyQ ? 20 amp controller $15.99 on amazon so i could sell the three 42w unisolar panels as a system, ready to install
those are the panels i removed to install the three New windy nation 100w poly panels
which increased my solar from 505 to near 700 watts
sometime this week i'm going to double up on the 8ga wire that is the feed from the panels to the controller
Ah, yes, you were running 12v panels thru mppt, as I've been doing recently. How did you have things wired back then? All the panels in series, I'm guessing? And now, in parallel?
