Hello,
( Heads up, I'm a newbie)
I am installing a solar array:
3s2p , 3 series 2 parallel
I have the Victron 150/70 Energy Smartsolar charge controller. ( and no I cant afford a second one )
I am installing on East West facing.
After watching Will ( truly excellent guy ) I need to install BLOCKING DIODES one on each of the two series. ( because only one of the two parallel series will be in the sun at any given time)
QUESTION: If I need a diode >117v and >10.2 amps, where can I buy one, or do I need to make it myself and put into a combiner box ?
I have looked online and could only find one MC4 type on amazon ( only one I could find on amazon had negative review because it "did not contain a Schottky blocking diode rather a "Schottky rectifier" and the reviewer went on to say "The mic rectifier has a much higher forward voltage drop, 0.750V"...."My 20A Schottky diode that I bought separately from amazon voltage drop of only 0.220V"
Everything is on hold until I figure out:
where / how to get the correct blocking diode ? / MC4 or installer box? / Are my numbers right ? ie: >117v & >10.2A ?
thanks for taking the time to read, all replies gratefully received...
