General Guidelines & Warnings
x
Mounting pole outside diameter MUST NOT exceed 48.5mm for at least the
top 0.5m. Larger section poles must not be used as this will reduce the tower
to blade clearance. In high wind conditions this could cause damage to the
Windcharger by allowing the blade to come into contact with the mounting
pole. A broken blade will cause turbine imbalance with consequent damage.
x
When turning, the Windcharger is capable of generating voltages in excess of
the nominal voltage. The turbine must never be allowed to rotate unless it is
electrically connected to a regulator or batteries. Connecting an open circuit
running turbine to the electrical system can cause serious damage to system
components owing to excessive voltage. Caution must be exercised at all
times to avoid electric shock.
x
Stopping the turbine – this may be necessary to undertake battery
maintenance. If possible stopping the turbine should be done in low wind
speed conditions. The turbine can be slowed by rotating or orienting the tail
fin upwind, this will slow the turbine sufficiently for it to be safely secured to the
pole with rope. Avoid leaving the turbine tied up for any period of time, we
recommend that the turbine either be covered to give protection from the
weather or removed and stored in a dry location. We recommend the use of
Marlec charge regulator that includes a shutdown switch.
x
Choose a calm day to install the equipment and consider other safety aspects.
No attempt to repair the system should be made until the wind generator is
restrained from turning.
x
The Windcharger is fitted with ceramic magnets, which can be damaged by
heavy handling. The main generator assembly should be treated with care
during transit and assembly.
x
High winds – in high winds the windcharger’s built-in thermostat may operate
to prevent the generator overheating. In this mode the output will cease and
the turbine will temporarily speed up until such time as the lower level
temperature is reached and the generator is once again connected and
charging. This may be seen to cycle in prolonged high winds particularly in
high ambient temperatures. If safely accessible you may prefer to temporarily
secure the turbine.
x
It is essential to observe the correct polarity when connecting the Windcharger
and all other components into an electrical circuit. Reverse connection will
damage the Windcharger and incorrect installation will invalidate the warranty
