This micro-hydro generator is for those with low head but high volume installations. It can utilize a maximum of 1000 GPM falling 10 feet to produce 1kW of power.
To gain enough head to operate this unit, water is channelled into a sluiceway. The turbine is mounted in an opening in the sluice bottom, with the draft tube extending to the water below. The water turns the propeller, which in turn runs the generator which produces electricity that is stored in batteries.
