You'll want to have a fuse or breaker between the panels and the charge controller... as well as between the battery and the charge controller—which you probably already have.I have 2 Kyocera 130 walt panels which I plan on connecting to a Prostar 30 controller and then to my house bank. What size of fuse or breaker will I need and is it placed between the panels and controller or ccontroller and battery?
Here's a link to the BlueSky MMPT controller that shows the breaker location.
I just installed two of these panels this weekend. The breaker is sized to protect the smallest wire in the circuit and should be installed closer to the battery side. If you're using 10 ga wire, us a 30 amp breaker. I'm guessing my panels should put out 20 amps in the best conditions, and probably closer to 14 to 16.
