| We
offer a variety of small hydroelectric generators
designed to be 12, 24 or 48 volt battery chargers,
operating from a relatively small volume of water.
They charge batteries whenever water is flowing
24 hours a day and the power can be drawn from the
battery as needed. As little as 100 gallons per
minute (GPM) falling 10 feet through a pipe, or
5 gallons per minute falling 200 feet through a
pipe, can supply enough power to run a small household.
In
areas where there is a long rainy season and a
mountain stream that can be used, a small hydro
system can work well with solar modules, both
charging the same battery. When it is rainy and
the solar modules are putting out less power,
the hydroelectric system will be at its peak.
By contrast, typical AC power hydro-electric systems
are designed to deliver ready-to-use 120/240 VAC
power and are not practical for most people. These
large hydros need a constant water supply large
enough to supply the peak power output that will
be required, (usually a minimum of several thousand
watts), and require hundreds or even thousands
of gallons per minute, depending upon the pressure
available. But these large systems can be cost
effective for those who have the water.

Harris
Pelton Turbines
The Harris Pelton turbines are suited well to higher head
and lower flow situations. Flow is limited by nozzle size,
(a maximum *"). With the Harris, adjustment to variable
flows is as easy as switching a valve and dialing in the alternator.
Higher flows are accommodated by the ESD Turgo Turbines. (They
can have nozzles of up to 1" in diameter.) This hydroelectric
battery charger uses a cast bronze pelton wheel and automobile
alternator in a white powder-coated aluminum housing. We can
supply these turbines with a Ford heavy-duty 80 amp alternator,
with one, two or four nozzles, depending on water flow and
power requirements. (PVC penstock with one shut-off valve
on two-nozzle machines and 3 shut-off valves on 4-nozzle machines
included.) These turbines can be fitted with nozzles up to
*" in diameter. Each hydroelectric system is custom-built
to match your site specifications. Please tell us your head,
flow, pipe size and length, and battery voltage when ordering.
Allow 2 to 3 weeks for delivery.
Head range: 20 to 600 feet • Flow Range: 4 to 250 GPM
• Maximum 12 Volt Power: 700 Watts
• Maximum 24 Volt Power: 1400 Watts

ESD
Turgo Generators
Energy Systems and Design hydro-electric battery chargers
use a cast bronze turgo runner to drive a long-life, brushless
permanent magnet alternator. A simple change of wiring in
the junction box allows this turbine to charge 12, 24 and
48 volt battery systems. These turbines come with cut-to-size
nozzles that can be user-set for up to 1", allowing a
very large flow in low head situations. They can operate on
heads as low as 5 feet with a flow of 40 GPM.

Aquair
Submersible Generator
If you have a fast flowing stream that is at least 13 inches
deep you can install a Submersible Generator without having
to build a dam or install piping. The Aquair submersible generator
is a special low-speed, high output alternator, mounted in
an oil-filled cast aluminum housing. It was developed to charge
lighting batteries on towed barges in the North Sea. When
mounted in a stream flowing 9 MPH, it charges a 12 volt battery
at 8 amps, or 2.4 kilowatt hours per day. It can produce 1.5
kilowatt hours per day in a stream moving 6 MPH. Estimating
the flow accurately is very important. We have found that
stream flow is often overestimated. For a low cost measuring
method, throw a floating object into the stream and time the
trip between two points. The propeller is made of ductile
aluminum, which can be hammered back into shape if it is hit
by floating debris. Replacement propellers are available in
case of severe damage. Installation requires secure mounting,
such as on a vertical pole from a bridge or on a cantilever
beam from one side of the stream. If your stream is subject
to violent flows due to thunder storms or flood control releases,
you should have some method of raising the generator out of
the way. The Aquair is 14.5" long. The generator is 8-3/8"
in diameter and the propeller is 12*" in diameter. It
weighs 30 pounds. A non-shorting charge control like the Trace
C30 or C40, or load diversion regulator like the Enermax may
be used for overcharge protection.

This wheel is made of cast bronze and it threads onto a Delco
or 80 amp Ford alternator. The pitch diameter (the place where
the center of the jet of water should be aimed) is 4".
It can be used with a jet of water up to 1". The nozzle
should be tilted at a 20 degrees angle from the horizontal
surface of the wheel. This is the runner in the ESD turbines.
