Wind Turbines
Small to medium wind turbines for off & on grid applications
We are a manufactures rep for several different manufactures.
Applications: farms, schools, and investment opportunities.
EWRS offers professional consulting services for renewable energy in the wind industry.
Many factors have to be considered prior to the installation. Soil samples for the proper foundation, wind assessments for production, electrical engineering, site planning by your county, grid hook up by your electrical provider. All turbines include inverters and controllers.

With the WES30 Mk1 connected to your farm, business, hotel resort, or any other location, you can harvest the wind and generate your own green energy. In other words, "produce it where you use it"! This powerhouse can produce, depending on the wind availability, an average of 600.000 kWh/year of reliable and renewable energy.
Efficient & Reliable
The technology and design of the WES30 is based on the WES18 with noticeable differences being its size, the tower and the blades. The WES30 is commonly used as a solitary wind turbine or in small wind farms. It has the reputation of being durable and reliable. The typical Dutch two-bladed rotor has a unique hinged system and a passive blade angle adjustment. This unique mechanism needs very little maintenance. Over 300 units are installed in many different locations, particularly in weak grids. The WES30 Mk1 is now often favored as a "behind-the-meter" wind turbine at business parks and factories. With its choice of towers up to 48 meters, the WES30 has very little impact on the environment and/or nearby airports.
The WES30 is also available as a Hybrid Wind/Diesel system. For more information, please go to our WES Hybrid System page.
Sturdy & User-friendly
The WES30 is a sturdy and user-friendly wind turbine that can be installed and used in logistically difficult locations. Some of the advantages of WES30 are:
- user-friendly
- easy in maintenance
- high reliability
- easy installation at difficult locations
- low loads on the gearbox and axle
- the AC/DC/AC principle allows the turbine to follow the grid
- mechanical passive blade pitch and active yaw applied
Size
With a 30m rotor diameter this a medium sized turbine. With 30, 39 or 48 meter towers it can even be erected with relatively small cranes at difficult locations.
State-of-the-Art
In 2007 WES introduced its new state-of-the-art IGBT Control Cabinet with the commissioning of first two new WES30 Mk1 wind turbines. Since then the new control and inverter cabinet has proven to be an extremely stable platform that outperforms any other turbine in this class.
WES has designed new software and combined this with new IGBT converters from Control Techniques Ltd., bringing the proven WES30 wind turbines into the 21st century.
The new Control Cabinet includes:
- a new user-friendly PLC interface
- dynamic output control
- remote monitor & control system
Adjustable-pitch,that means wind turbine blades could change the degree when the wind speed to be higher(over the rated wind speed) to keep the wind turbines always in rated speed area.
Third: Automatically Tail folding, When the output power exceeded the limit value, the control box give instruction signal and the battery(12V) supply power to make the steel wire rope in the electric winch to pull the tail vane in a speed of 0.050.1m/s , so as to drive the rotor yawing, when the yawing angle reach to 60°, the “Push rod” will be pushed, brake system will stop the running of rotor.

Most mid size homes use approx, 2000 KWs per month. So if you generated more KWs that month, you would sell it back to your electrical co op. If this continues throughout the year you will receive a check from your electrical co op.

Sweden SKF Bearing:Its costing price is 5~6 times higher than domestic ordinary bearing,and its quality is the one of the best bearings in the world,it could be used at least 15years .Other factory’s only used with domestic ordinary bearing,theirs only could be used few yesrs.
Fastener We use 8.8 10.9 12.9 grade fastener the cost is higher 4times than domestic ordinary fastener.It means the quality is better than others.Other facotry’s only used with domestic ordinary fastener too.
We offer 10 -KW to 250KW wind turbines for homes and businesses. Off or On grid!
If you are interested in lowering or eliminating your electric bill. If you want to help reduce carbon emissions into the air we breath. And in some cases you can produce enough power to sell back to your electric provider, then you need to research wind energy.
The cost of energy is not going to decrease so why not invest and become a little greener.
Energy waste recovery for homes and businesses was developed by our company and is the best way to see your energy loss, make corrections to those areas consuming wasted energy. Then apply an additional reliable energy source for your future.
Wind turbines are not for everyone however if you own a business or home in a windy area you need to seriously consider wind energy.
A 7mph you will start producing power. Our wind turbines have been tested at 80 mph winds with gusts over 100 mph. Our generators do not have brushes they are magnetic with no gears. Little to no maintenance.
Before investing into wind turbine we highly suggest scheduling a energy thermal inspection first. Locating and repairing those areas in your home or business from energy waste first will help in purchasing the correct turbine system. You maybe wasting 100 to 500 KWs per month and not even know it.
Give us a call to see which system would be right for you.
Call 503-884-4866 for free consultation!
Tower The configuration of tower is Six pyramid foundry of ferromanganese,
So towers are strong and hard to inflect when strong winds come, the tower body has galvanizing plastic coating outside,so it could work between -40 to 50 c temperature condition,antirust anti-salt corrosive (sea water corrosion) and so on.
Wind turbine-Engine room. Designed of steel and have galvanizing and plastic coating outside, at least 15years anticorrosive and antirust.
