Hi,
I have an off grid cottage with 3.6kW on the roof. Unfortunately the surrounding forest is limiting my solar access. To remedy this, I plan to add 4kW on a 20 ft high rack about 130 m from the cottage where I get better site lines. I'm thinking that I need to run cables from collector pairs to my charge controllers in the cottage. This would keep the voltage at about 60 v and avoid excessive losses after the inverter. Does anyone have any suggestions or rules of thumb for acceptable line losses?
