This Long version mounted on a Tecumsineeh OHV engine. -254 The little perf-board in the lower center with the ICs and other bits on it is the actual controller circuit. The silver bracket below it holds two buttons that allow me to manually toggle the unit between charging batteries and dumping power to a secondary load. The big, black heat sink on the lower left has two 40 Amp blocking diodes bolted into it. I am only using one right now, but I could easily add a second wind turbine or even a photovoltaic solar panel to the system using the second one. The double row of gold rectangles across the top is a dummy load made up of high-Wattage resistors. It has taps at 2 Ohm intervals. I use it as a secondary load to dump power from the turbine into when the battery is fully charged. I also use it for testing purposes to load test the turbine. Eventually excess power from the turbine will be dumped to something more useful like a water heater or a second battery bank. Below and to the left of the dummy load is the main fuse for the wind turbine. The small gray cube is a 40 Amp SPDT automotive relay the only part I had to purchase which sends the turbine power either to the batteries or to the dummy load. Along the right side is the terminal block which allows me to connect everything together.
