Hello crowd,
I would like to pick your brain
I have multiple panels that are mounted close to each other but in different angles towards the sun and with different shading (they are on a sailboat).
Therefor (and for redundancy reasons) I want to connect each panel via a mppt controller to the battery bank:
I am now wondering if I can simplify the cables and use only 1 negative cable between the charge controllers and the panels (given that I size the negative cable to handle the load from all panels):
Do you see negative effects? Does the negative and positive cable between the controller and the panel need to be of the same length and strength? If so why?
Thanks a lot!
