I already have 400W of PV, and a home-made CHP unit for higher power AC power and battery charging. I am about to rewind a 7kVA generator to charge 24V batteries and supply AC power from the same unit. A wind turbine and standby cord-start power will follow for battery charging if main batteries get too depleted to start the CHP unit. My plan is to be completely fossil-fuel free by next winter,except for some heavier power tools. Excess power from that turbine will be routed to a resistive load, controlled to either use for heating, or overspeed control. Slowing the turbine will dramatically reduce the power that it collects from the wind. I will also experiment with an exhaust turbine driving a high-speed PMDC motor.
