1 Introduction
The Windy Boy inverters make it possible to operate small wind turbines as grid-
connected systems. Grid-connected means that the energy generated by the wind
turbine can be fed directly into an existing house power grid, a stand-alone power
system, or the mains supply.
To this end, the Windy Boy converts the direct current (DC) from permanent-magnet
wind turbines, which vary with speed, into grid-compatible alternating current (AC).
The Windy Boy requires the constant presence of mains supply voltage!
The Windy Boy 5000 / 6000 complies with all the VDEW (Verband der
Elektrizitätswirtschaft – German Electricity Industry Association) regulations for the
connection and parallel operation of electrical power units to the low-voltage grid of
the electricity supply company. This also encompasses the regulations of the German
Professional Association for Precision Engineering and Electro technology relating to
"Automatic switching of electrical power units" (SMA grid guard) and/or DIN VDE
0126. In addition to this, the Windy Boy 5000 / 6000 conforms to the
electromagnetic tolerance regulations and the low-voltage regulations of the relevant
combined European norms, as confirmed in the CE conformity declaration (10.3
"Declaration of conformity (CE)” (page 63)).
The documentation provided here covers all such topics that are of interest when
operating Windy Boy 5000 / 6000 inverters. In addition to explanations of the
operational methods of the device and detailed technical data, advice as to data
capture and analysis is also provided.
Information relating to the installation and commission of the Windy Boy 5000 /
6000 should be taken from the installation instructions delivered with the device. The
Windy Boy 5000 / 6000 inverter has a special operational mode for wind turbines
which allows performance adjustment to the characteristic curve of the generator. In
this way you will obtain maximum yields from your wind turbine.
A wide input voltage range, high efficiency and a freely configurable output
characteristic curve with the highest level of reliability are only some of the properties
that are useful for your grid-connected system, or in a stand-alone system when
combined with the Sunny Island.
The installation of the Windy Boy 5000 / 6000 may only be done
by qualified technicians. The installer must be approved by the
utility company. Please read the installation guide carefully before
you begin with the installation. The installation of utility interactive
power sources must be compliant with all applicable regulations of
the utility company and with all applicable regulations and
standards.
