I have 1 x 100 watt solar panel and two connection locations (roof and portable - on ground). Therefore, i have 2 positive wires going to a breaker and then 1 wire going from this breaker to the MPPT 75/15 CC. I will NEVER have two panels connected at the same time. Only one. Anyone see an issue with this wiring setup?
As long as your positive can't ever ground on the unused connection and you fuse things, no issues! I have 4 of these for summer myself (vs winter) and a mobile cord connection for portables that can be moved to various more sunny spots as needed -no issues for years!
Thanks, Trina. I'm not sure i follow on the ground comment. I was going to connect both negative wires to the same PV port on the MPPT CC.
