1 Introduction
The Windy Boy inverters make it possible to operate small wind turbines as grid-con-
nected 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 grid.
To this end, the inverter converts the direct current (DC) from permanent-magnet wind
turbines, which varies with speed, into grid-compatible alternating current (AC). The
inverter requires the constant presence of mains-grid voltage!
The Windy Boy 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 Associ-
ation for Precision Engineering and Electro technology relating to "Automatic switch-
ing of electrical power units" (SMA grid guard) and/or DIN VDE 0126. In addition
to this, the Windy Boy conforms to the electromagnetic tolerance regulations and the
low-voltage regulations of the relevant combined European norms, as confirmed in
the CE conformity declaration (9.3 "Declaration of conformity (CE)” (page 61)).
The documentation provided here covers all such topics that are of interest when op-
erating the Windy Boy inverters. In addition to explanations of the operational meth-
ods of the device and detailed technical data, advice as to data capture and analysis
is also provided.
Information relating to the installation and commissioning of the Windy Boy should
be taken from the installation instructions delivered with the device. The Windy Boy
inverter has a special operation 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 charac-
teristic 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 1100 / 1700 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.
