How to determine proper wire size to use between Panels and MPPT Controller
Trying to understand how to best/properly determine the correct cable/wire size to use between two 440 Watt Solar Panels and an MPPT Charge Controller. The distance between the panels and the charge controller will be between 60 and 100 feet. We are installing a 24 V system and figuring out the wire sizes for the load side is not a problem. My confusion comes from trying to understand what voltage the panels are operating at.
