Dump/diversion load controller Mar 10, 2020 0:14:56 GMT Select PostDeselect PostLink to PostBack to Top Post by CharlesM on Mar 10, 2020 0:14:56 GMT So I've got 600W of Sunpower panels on the roof of my RV, and a 100Ah battery. The battery is getting back to fully charged by 10-11 AM and stays there till about 6 PM!So there is a LOT of excess PV power, that is being wasted.I've got enough battery for my typical electrical uses for now, so I don't want to just but a larger battery until I need one.But I am thinking of ways to use the excess PV, I could heat water in a separate tank or I've thought about a hydrogen electrolyzer and then use the gas for cooking.Has anyone found a dump/diversion load controller they like? I know Xantrex offers the C40 CC which can be used in Diversion mode. Does anyone use excess PV production after the batteries are fully charged? What do you use it for?
