Not sure if this one is wind, solar, or both.
Mine responds a Lot faster. The lag time is very small. The voltage is stable.
Mine can be set up to divert only the solar amps away from the battery, no need for a dump load.
The solar part can be added to a windmill using the circuit, or vice versa, but the windmill will need a dump load.
Diverting the incoming amps is easy with solar, but not such a great idea with wind.
Mine is one stage. Pick a max voltage and thats the max voltage. Much like a SS-X solar controller.
Snow Crow could send the extra solar amps to the water heater, before they even get to the battery? I'll have to think about that a little more. Gotta be easier than the IGBT!
