Re: Mainsail comes through again with solar
Genasun charges something like $25 to custom program their MPPT controller for your battery type, if they don't already offer a matching model. I'd expect multiple controllers to fight each other as they have no way to determine which one is "talking".
Their tech support responds to emails same day usually.
