Advantages at a glance

Gruppe 79

Profitable

Standardised technology, project-specific configuration, low operating costs and high energy yields are the basis for a secure investment and short amortisation periods.
Planung Und Errichtung

Mature and suitable for industrial use

Every part of the system is mature technology and has been tested on test benches and prototypes over a long period of time.
Gruppe 80

Strong earnings at all locations

Our systems generate over 100.000 kWh of energy yield per year through location-specific adjustments, even at moderate wind locations.
Geringe Stromkosten

Low electricity costs

Our systems are designed as self-consumption systems. Assuming a high self-consumption rate, electricity costs can be reduced by up to 50% and stabilized for 20 years. Excess electricity can be fed into the public grid.
Gepruefte Qualitaet

Tested quality

Our system is developed according to the standard for large wind turbines, IEC 61400-1. The Certification is carried out by TÜV-Süd.
Einfaches Genehmigungsverfahren

Simple approval procedure

Our systems have a maximum height of 50 m and do not require any priority areas for wind turbines to be installed. As a private branch exchange of a company, they are not significant in terms of space and only require a building permit.
Gruppe 86

Extremely quiet

The system concept, optimized rotor blades and active rotor blade adjustment ensure low-noise operation. Even at a distance of 200 m, the nightly requirements for residential areas (<35 dB (A)) and from 80 m for mixed areas (<45 dB (A)) can be met.
Umwelt

Environment

The system fits into any environment and does not change the landscape.
Intelligent

Intelligent

The optimized control of the systems is based on current industry standards. A self-sufficient safety system prevents unnecessary loads and critical system states.
Gruppe 87

Maintenance-friendly

Completely dispensing with maintenance-intensive hydraulic systems and a main transmission, while simultaneously using unique remote monitoring and diagnostics, ensures long maintenance cycles> 1 year and low operating costs.
Gruppe 83

Innovative

A unique active rotor blade adjustment (pitch), innovative rotor blade technology and optimized controller behavior ensure the greatest possible energy yield.
Gruppe 78

Flexible

Our systems are designed for complex grid requirements by means of full converter and directly driven synchronous generator. They are black-startable and can be used for isolated networks.
Gruppe 81

Perservering

Developed according to the standards for large wind turbines, for the most difficult conditions and an operating time of over 20 years.
Unbedenklich

Harmless

Completely dispensing with hydraulic systems, cooling media and a main transmission reliably prevents environmental damage.
Gruppe 85

Communicative

All operating data, the current performance and the status of the system at a glance, whether from home or on the go.
Gruppe 82

Efficient

Aerodynamically optimized rotor blades, a directly driven, variable-speed drive train and optimized plant operation ensure the highest possible energy yields.

FAQ

Frequently asked questions

The turbines are designed to have a lifespan of 20 years. If it can be proven that the turbine has been operated below its design loads, it is possible to extend this period.

Yes, these can be made available according to the wishes of the customer.

Yes, this can be realized according to the wishes of the customer.

An external power socket is not in the scope of delivery, however it can be included according to the wishes of the customer.

Maintenance is carried out annually on the turbine according to a formal maintenance plan. This requires that the turbine be stopped for a period of approximately four hours. You may carry out the maintenance yourself, provided you have received the proper training to do so.

The foundation may be laid by the customer provided the specifications and requirements are adhered to. A preexisting foundation may also be used, under the same conditions as above.

Yes, you can see the power, the turbine status and the current wind conditions via the customer portal.

Yes, the turbine is designed and certified according to the IEC61400 standard. Operational ranges, up to and including extreme gusts with an occurrence frequency of once every 50 years, are clearly defined within this standard. The turbine is not only designed to withstand these loads but also loads above and beyond these as a large factor of safety is used in the design process.

A normal three phase domestic house connection which can deliver up to 63A is sufficient. The turbine is equipped according to German grid code VDE DIN 4105, so that it halts power feed-in during a grid fault. In this way the turbine poses no risk to other devices connected to the grid.

This depends on your site. For a site with strong, steady wind the pay-back period is about six years. The period will be longer for a less windy site.

If there are no large obstacles (e.g. buildings, trees etc.) in the direction of the prevailing wind to create turbulence, then your site may be suitable.

Yes, you can start and stop the turbine via the customer portal.

That is technically possible. The basis turbine is laid out in such a way to allow realization of these requirements through the addition of specialized electrical equipment. The equipment required will be specified on a case by case basis and fit to the requirements of each project individually.

Of course you can operate your turbine at night. The noise emissions are very low. The turbine has undergone a noise measurement study and qualifies to be operated in a residential area at a distance of 100m from dwellings.

An additional, certified package can be employed to monitor the atmospheric conditions and to cause the turbine to shut down during periods when increased bat activity is likely. The same module restarts the turbine once conditions have returned to normal.

Due to its low height and pleasant design, the turbine in our opinion does not affect the landscape significantly. On the contrary, the turbine can afford you as customer a positive public image.
