Hello Phil, I posted a reply to Cooper about the Renogy 50DC combi controller. I personally been using this control for about a 1-1/2 year that keeps 3-100Ah Battle Born batteries charged as well as managing 480 watts of solar. This unit has a built in DC to DC controller as well that isolate the truck batteries when the engine isn’t running.
