Windy Boy, Grid Connection of Small Wind Turbine Systems

In contrast to multi-megawatt systems, small wind turbines are used mainly as battery chargers for stand-alone power supplies, as heating mills for the support of heating systems, and as wind pumps for water supply systems. There are a number of very attractively priced wind generators for these application areas. In recent years another trend has become evident: the use of small grid-connected wind turbines from which the energy generated is fed into existing public grids or stand-alone grids, e.g. in combination with Sunny Island. Indirect feeding guarantees maximum flexibility: the energy generated can either be consumed or supplied as excess energy to the public grid without the need for interim storage in a battery. The resulting savings potentials are immense as there is no longer any need for expensive high-maintenance
batteries.

The conversion of direct current into alternating current in small wind turbine systems is now easier than ever before: with the Windy Boy inverters it is possible to operate small, grid connected wind turbines with permanent magnet generators, and with 3-phase rectifiers downstream. The Windy Boy converts the rectified DC current from a wind generator, which varies with speed, into grid-compliant alternating current (AC). In order to protect the inverter from excessive input voltage, the system should also be equipped with overvoltage protection, available from many generator manufacturers.

Diversity
With experience from the use of the proven Sunny Boy inverter in more than 500,000 applications all over the world, we now have the Windy Boy product line, a new family of inverters for connecting small wind turbines to the grid. There are various device types available within the 1000 to 6000 W range, all of which are suitable for use with wind generators of various manufacturers and in different power classes.

High Yields
It is only possible to achieve high yields from your wind turbine if the inverter is precisely synchronized with the output characteristics of the wind generator being used. Furthermore, and in contrast to photovoltaic applications, constant and sudden load changes have to be taken into account. The Windy Boy inverter has a special operational mode for wind generators which allows performance adjustment to the characteristic curves of many different manufacturers’ generators. Adjustment can also be made for the different wind strengths of the various wind turbine locations.

Universal
The system can be used almost anywhere in the world with minimum installation costs and simplified authorization procedures thanks to its transformer-based concept, the grid guard automatic disconnection unit, its automatic 50 Hz / 60 Hz recognition, and a number of special country approvals.

Robust
The ensured operation of the system in extreme climatic conditions is of particular importance in the wind sector. The Windy Boy is suitable for indoor and outdoor installation, e.g. directly on a mast, thanks to its particularly robust housing and waterproof plug connector.

Monitoring
As well as a display, there are various options for diagnostics, data visualization, data storage and remote maintenance of your wind turbine system via standard interfaces (RS232 and RS485), SMA Powerline or wireless data transmission. Compatibility with all SMA communication products offers you a wide range of applications, including system monitoring via the Internet.

SMA Sunny Boy Inverters  

Europe's most popular Grid-Connect inverters, each designed to be used with one series string of between 6 to 24 photovoltaic modules depending upon inverter type.

Units can be linked in parallel allowing extreme system design flexibility with the possibility of low cost system expansion and maximum system efficiency. This makes the inverter ideal for use alone or as part of a large PV plant.

The SMA Inverter, the Heart of every Solar Power System

A solar power system is only as good as its inverter. It converts direct current from the solar cells to grid-compliant alternating current. Its quality determines the yield; it is the heart of the solar power system.

Solar power systems are just as individual as the buildings on which they are installed. Therefore the installation engineer must be presented with a broad range from which to select the inverter which optimally suits the PV generator and which guarantees the highest yield.

As the first manufacturer of an inverter suitable for mass production, SMA has concentrated on repeatedly diversifying the implementation possibilities with new technologies, so that today any system constellation from 400 Wp and upwards can be optimally realized with an SMA inverter.

Flexibility
SMA inverters can be installed indoors or outdoors.

Reliability
We develop and manufacture our inverters for a life span of more than 20 years.

Durability
A 5-year warranty as standard (optionally extendable to 10 years), dedicated telephone servicelines, and additional services such as replacement devices, comprehensive service contracts and the ”no worries” package Sunny Easy, guarantee high investment security.

Control
All SMA inverters can be combined with a wide variety of components for system monitoring, from the wireless Sunny Beam to the Sunny WebBox for diagnostics and maintenance via Internet from any PC, anywhere in the world.

Safety
With the SMA grid guard 2 and ESS, SMA provides the most reliable safety systems currently on the market.

Made in Germany
All SMA inverters are developed and produced at the company headquarters in Niestetal, near Kassel, Germany.

The Choice is Yours: with or without Transformer

SMA inverters are available with or without transformers. While the transformerless concept offers the ability to use such latest technologies as H5 topology and is also extremely lightweight, the transformer device is the first choice for those who want galvanic isolation. In addition, transformer- based devices offer the best possibilities for combination with thinfilm modules.
Regardless of which technology you choose, you always acquire the highest SMA inverter development standard for the respective device.
