I've got an opportunity to install an Archimedean screw micro hydro scheme for power generation on a river running alongside my business and was planning on using the energy generated to power my MX and the 3s (when they arrive). I've been told that the turbine will generate 5kW peak power, delivering 30MWh per year. I plan to use all the energy myself and feed none back to the grid (electricity utility only pays me 8c/kWh, whereas 1kWh is worth 5km range and at local diesel rates that's worth about 50c). I imagine my setup will be as follows... turbine feeds an inverter that then pipes energy to a battery pack. Can I then feed this DC directly to the vehicle's batteries in the same way that the Supercharger does or would I have to go about rectifying and feeding it as AC a la the HPWC?
