Details

Denis Ledbetter builds hydropower battery charging generators for a wide range of site conditions: minimum about 10 feet head, to over 300 feet. It installs in a small shelter at the low end of a 2 to 6 inch diameter pipeline. The water intake at the upper end of the pipe requires a screen to keep leaves, rocks, or fish from entering. 1 year warranty

High pressure water jets through 4 nozzles to spin the pelton wheel using pressure built in the downhill drop of the pipe. The microhydro turbines include a cast metal housing, nozzles, wheel, and alternator and has a clip on meter and necessary controls.

PERMANENT MAGNET BRUSHLESS ALTERNATOR is available on new turbines, or can be retrofitted to existing installations. The brushless alternator uses a permanent magnet rotor which has a  mechanically adjustable strength of magnetism.  No brushes to wear out means lower maintenance chores.


The Harris PM warranty only applies to systems with 300' or less of head.The chart below shows watts generated with many combinations of head and flow. Output may vary. To determine if your site is feasible, look for 25 watts or more. If you've got it, get our hydro planning papers and videotape. Tell us the data requested above, and/or ask for our hydro planning papers and hydro videotape.

EXAMPLE: A one nozzle turbine with the Harris PM alternator on a 2 inch pipe with 75 foot head and flow of 18 gallons per minute shows on the chart to generate about 115 watts (9.5 amperes 12 volts). Likewise, 25 feet head and 50 gallons per minute would give the same power, but the increased flow would require 4 inch or larger pipe and a 4 nozzle turbine. Each nozzle passes a maximum 20 gpm.
