How do I hook up my Yeti 1400 lithium battery system to my friend’s RV roof-mounted solar panels — so we can share the charging juice, so to speak... Thanks! My friend’s RV is a Winnebago Travato 59G and has 300 watts of solar power panels on the roof... Has anyone figured out a way to essentially “share” the solar panel’s output between two vans? If so, I’d appreciate the knowledge-base share. ?
