Can anyone confirm my wiring for 4 x 120w panels, my controller is 50 v max, so im going this layout.

Do the panels have reverse voltage diodes fitted? They need to have to prevent one panel feeding back into the others.
What sort of controller have you got?

 

[Rufus2502]

They have diodes, and i'm using a basic pwm controller.

Good controllers are worth it as they do a better job of converting low output into usable voltage.

wiring is correct !

I plan on fitting a MPPT controller when one comes up secondhand or on special offer. I never buy full retail price if i can help it.
