ES&D 'Easy Tune' Hydro Turbine:
Energy Systems and Design 'Easy Tune Stream Engine'
This is the latest development in ultra high efficiency water power equipment from this innovative design company.
The Easy Tune puts out significantly more power and at a lower speed than the Stream Engine.
Up to 60 amps is standard, given sufficient head and flow. Up to four nozzles, but two are standard permit a wide range of flow to be used.
The key feature is that the unit can be 'tuned' or adjusted while it is in full operation by means of aligning the stator coils for maximum output.

ES&D Hydro Turbine:
Energy Systems and Design 'Stream Engine'
Bottom view of the 'Stream Engine' water turbine generator.
Because the Stream Engine uses a Turgo Turbine runner, it can accommodate a much greater water flow than an equivalent sized pelton turbine, such as the Harris. In situations where water volume is available, and at low heads, the stream engine will be a better choice. For high head sites with limited flow, consider using the Harris Turbine.
|
|
ES&D Hydro Turbine:
Energy Systems and Design 'LH 1000' propellor turbine
For heads up to 10 feet with a large flow volume. These turbines use the same permanent magnet generator as the Stream Engines. A plastic 'draught tube' or suctin discharge pipe connects to the bottom of the turbine, on the left, and drops down to below water level thus keeping air out of the suction head.
|
|
Harris Hydro Turbine:
This Harris generators also use a permanent magnet generator. Shown here is a unit with an automotive alternator installed. These are no longer available as the efficiency with the permanent magnet generator is much better.
For use as stand alone power generation at cabins, remote off grid homes, camps etc.
|
|
Harris Hydro Turbines:
Bottom view of the Harris Turbine, showing the four inch diameter Pelton runner. Up to four nozzles can be used at the same time. For very low flows and high heads this is a good choice.
Use as you would an ES&D turbine, for stand alone power generation at cabins, remote off grid homes, camps etc.
|
|
Induction Turbine Generator:
This is a special kind of generator. It uses a high voltage induction motor as the generator. This permits long distance transmission of the electrical energy. Distances of up to thousands of feet are possible, and voltages up to 240 volts, three phase. A special controller is required together with transformers. The power is then stepped down to battery voltage, and then handled the same way as with a Harris or ES&D unit.

Older Modules:
While the trend is for much larger 400 to 500 watt modules, we still have some hard to find low power modules. We still have some old Kyocera modules in stock from 60 to 80 watts as well as older Sharp and Siemens 75 watt.
Other sizes available, call for quote.
|
|
Various modules:
300 to 370 watt modules shown here. Longi bifacial modules up to 545 watts are now the standard size for large arrays.
For direct grid tie applications, the current trend is to use the Enphase DC to AC inverters on each module. Grid tie with no batteries and no single large inverter is now possible.
|
|
Other smaller modules:
High effiency multicrystal modules available in sizes from 10 to 30 watts.
Shown here is a British Petrolium 20 watt module. Suitable for SCADA telemetry systems or other applications where the power demand is low.
Ideal for maintaining a single car battery or for a demonstration setup.

Controls:
Morningstar is a leader in advanced PWM solar charge controls.
Shown here is a Morningstar ProStar PWM controller with meter.
Rated for 30 Amp 12 volt, but you should not exceed 25 amps in actual use.
|
|
Controls:
The C-60 and C-40 are PWM charge controlers for solar or micro hydro applications. I have used lots of these units and all are still working well. They can be set as diversion controllers for micro hydro use, or as load controllers, to shut of loads if the battery gets too low.
C-60, good for up to 48 amps, 12, 24 volts: -------- 225.00
C-40, good for up to 30 amps: 12, 24, 48 volt:-------- 195.00

Inverters:
Sine Wave models. The SW series is regretabely being phased out. They are rated up to 4000 watts and produce excellent power.
The XW series is for grid intertie and has similar speecs as the SW series.
SW 4024, SW 2524
XW 4024,

|
Inverters:
DR series of modified sine (square) wave inverters. These have been around for ages and are extremely rugged and reliable. They are still available, but the pure sine wave inverters are now the norm, costing less than the modified sine wave units did in the 1900's. The DR series are replaced by the newer TR series.
DR 1512 DR 1524
DR 2412 DR 2412
DR 3624
