Freestanding Towers; Roof Mounting - ECLECTIC ENERGY D400 User Manual

Freestanding Towers

For small wind turbines such as the D400, free-standing towers
can take the form of old telegraph poles, or a self-supporting
steel lattice tower.
It is important to ensure the tower's foundation is sufficient such
that the tower will withstand a horizontal load of 70 kg at the
height
of the turbine.
In order to ensure that an acceptable blade to tower clearance is
maintained, a stub tower should be used between the D400 and
the free-standing tower. See illustration.

Roof Mounting

Due to its quiet, vibration-free operation, the D400 is
particularly suitable for rooftop mounting.
Mounting on buildings has the advantage of achieving additional
height. There is also often a localised increase in wind speed
due to the compression effect of wind flowing over the ridge of
the roof. This is particularly true when the prevailing wind is at
90 º to the roofline. Generally speaking, a mount height of 1.5 to
2.5 metres above the ridge line will place the turbine in the best
air flow.
It is important that the building structure and the mounting
bracket attachment is sufficiently strong to support the turbine
adequately in all wind conditions. Despite D400's quiet,
low vibration operation, the installation may benefit from
additional, anti-vibration mountings to prevent the transmission
of vibration into the building structure.
Eclectic wall mount brackets, incorporating anti-vibration
elements, are available - contact your dealer or Eclectic Energy
Ltd. for details.
