Micro Hydropower

HI-Power
Low-Voltage Hydroelectric Generators

HI-Power is now offering a low-voltage brushless PM (permanent magnet) generator.  This user-friendly unit requires no adjustments and is more efficient than car alternator types over a wider range of head and flow.

Head Range: 40 – 400 feet
Flow Range: 5 – 100 gpm
Maximum Power: 1500 Watts
Efficiency: 30% – 70%
Battery Voltage Options: 12V, 24V, 48V, 120VDC

HI-Power low-voltage hydroelectric generators are available in four voltages for direct battery charging, including the 48V and 120V units, which allow the use of smaller gauge wire between the generator and the battery.  An MPPT charge controller such as the OutBack FM-60 can be used to efficiently step the voltage down for charging and regulating 12V, 24V or 48V batteries.

The sealed permanent magnet alternator is mounted on an anodized aluminum turgo housing with the 4-inch stainless steel Hartvigsen Turgo Runner.  The external rectifier is water-cooled and all fasteners are stainless steel.  It comes with an induction meter and 3 feet of 1-inch flexible hose per nozzle.  Order multiple nozzles for convenient adjustment to varying flows.  Alternator has two enclosed 6203 bearings which should be changed every 4-10 years, depending on use.  Pictured with 3/4 inch brass nozzle holders.  1-inch plastic nozzle holders also available.  Also available Skirt fits in 10.25 inches.  When ordering, specify battery voltage, transmission line length and size, flow, pressure, pipe size and length.

Harris Hydroelectric
Pelton Turbines

This hydroelectric battery charger uses a cast bronze Pelton wheel and a brushless permanent magnet alternator on a white powder coated aluminum housing.

Head Range: 20 – 600 feet
Flow Range: 4 – 250 gpm
Maximum 12-volt power: 700 watts
Maximum 24-volt power: 1400 watts
Maximum 48-volt power: 250 watts

They are available with one, two or four nozzles, depending on water flow and power requirements.  (PVC manifold with one shut-off valve on two-nozzles machines and 3 shut-off valves on 4-nozzle machines is available).  These turbines can be fitted with nozzles up to 1/2″ in diameter.  Each hydroelectric system is custom-built to match your site specifications.  Please tell us your head, flow, pipe size and length, electrical transmission line length and battery voltage when ordering.  The new permanent magnet (PM) brushless alternator pictured here is 15-30% more efficient than the automotive alternator used in the past; and they last longer. Fan kit is recommended when producing over 500 Watts.
