Hydroelectric DC Charging

Use to charge a 12, 24 or 48 volt battery 24 hours a day either alone or with solar modules, wind generator or engine generator. A 100 gallons per minute of water falling 10 feet or 5 gallons per minute falling 200 feet through a pipe can generate 80 watts. This is about 1.9 KiloWatt hours a day and would equal about five 75 watt solar modules in a 5 peak sun hour location.

The amount of power available depends on the dynamic head, the amount of water flow and the efficiency of the hydroelectric unit.

Most micro hydroelectric turbines operate from the pressure at the bottom end of a pipeline. This pressure is measured in pounds per square inch (PSI) and is directly related to the head, or vertical distance from where the water goes into the pipe at the top of the pipeline, to the turbine located at the bottom of the pipeline.

You should know your Total Head, Flow rate in gallons per minute, Pipe length needed, Wiring distance from hydro unit to batteries.

Head in Feet times Flow in GPM divided by 10 will equal the approximate Watts available

Turgo Stream Engine

The Stream Engine is designed for use in battery-based power systems, with electricity generated at a steady rate, and stored in batteries for use at higher rates than is generated. During times of low demand, power is stored. An inverter is used when residential AC power is desired.

Water from a stream is channeled into a pipeline to gain enough head (the vertical distance the water falls) to power the system. The Stream Engine operates at heads of about 2m (6 feet) and upward. The water passes through a nozzle, where it accelerates, strikes the bronze turgo wheel, and turns the generator shaft. Up to 4 universal nozzles can be installed on one machine. The included Universal Nozzles are adaptable in sizing from 3mm(1/8 inch) to 25mm(1inch).

Typically, these systems operate at 12, 24, or 48 volts, with reconnectable wiring which allows the user to install a standard Stream Engine at most sites. Custom windings are also available which can produce high voltage (120, 240) at any site.

Head range: 10’ to 400’, High flow, up to 1000 watts, adjustable 12,2 4, 48 volts. Long life brushless permanent magnet alternator, bronze turgo runner, cast aluminum housing. Optional Bronze housing for salty environments is $700 more.

LH1000 Low Head Propeller Turbine 

 

The LH1000, like the Stream Engine, is designed to operate in conjunction with battery-based power systems, in order to store electrical power for use at times when consumption exceeds generation. Power is stored during periods of low demand. When AC loads are desired, an inverter is needed to convert stored DC to residential AC power.

To gain enough head to operate the LH1000, water is channeled into a sluiceway. The turbine is mounted in a 7” opening in the sluice bottom, with the draft tube extending to the tailwater below.

The water turns the propeller, creating shaft power. This, in turn, powers the generator, producing electricity.

The LH1000 typically operates at 12, 24, 48, or 120 volts. It can be specially wound to operate at 240 volts, when necessary. Employing the same adjustable, permanent magnet generator as the Stream Engine, the LH1000 has reconnectable wiring for use at a wide range of sites.

LH1000 120 lbs    $170 shipping   $3000 Special  $2850        

 LH1000HV High Voltage Option  $275
 LH1000HA High Current Option  $275

The Stream Engine and LH1000 both employ a brushless, permanent magnet alternator that is adjustable, enabling the user to match turbine output to electrical load. It has a higher efficiency than previous alternators, and is capable of outputs over 1 kW, while requiring virtually no maintenance. These microhydro systems employ high efficiency, precision-cast parts, and non-corrosive alloys for long life and durability. A digital multimeter accompanies each turbine for measuring output amperage. These units can be used in stand-alone, or grid-tied systems.

POWER OUTPUT & SITE ASSESSMENT

To determine the power available at a site, head and flow measurements must be taken. Flow is the rate at which water moves, measured in liters per second (l/s) or gallons per minute (gpm). This can be measured by channeling the water into a pipeline, then into a container of a known volume, noting the time it takes to do so. A weir can be used to measure flows in larger streams. Head can be measured by using a transit, by looking along a level, or by using a pressure gauge at the end of the pipeline. An altimeter can also be used, so long as it is accurate, and sufficiently sensitive.

It is important to keep in mind that output can only be accurately determined if head and flow measurements are made correctly, so care should be taken during this process. Two other important factors in a site assessment are system voltage, and transmission distance. The voltage and distance the power must travel can affect the efficiency and cost of your transmission lines.
