We have an EasySolar with a PV array and generator to keep the bank of 48V batteries charged. This is all working well, but would like to consider the addition of a vertical wind turbine to help in the winter, Important here in Orkney where the winter nights are long! Have been looking at TRiStar controllers, dump loads, etc but getting confused about how this might all work together without the PV controller and wind turbine "fighting" each other to charge (and not overcharge) the battery bank. Anyone done this type of thing before? We also have a BMV712 monitoring the current/voltage.
