Connecting two solar panels to a single charge controller
Hi!

I am to connect 2 solar panels to a Morningstar Prostar Ps-30M 30A charge controller.

The Solar panels are both 12 but one is 80W and the other is 120W. They are of different brands, but will be mounted in the same direction.

Can I just parallel wire theese panels to the charger, or do I need to use blocking diodes on both panels?

I will ble very happy for any help :-)

Br Fredrik
