Theoretical power production for small wind turbines when
the wind speed is 10 m/s.
The 200W unit has a rotor diameter of 2.1m, giving a swept surface area of 3.14m2.
Wiring
Wiring of the wind turbine is very straightforward. The wind generator is a 3-phase
alternator, generating 3-phase AC. This is rectified by the charge controller, which
then feeds DC to the batteries. Once the batteries are fully charged, the charge
controller diverts the excess power to the ‘dump load’ output, where it can be
connected to a resistive heating load. Specially designed resistive air heater dump
loads can be purchased through your supplier, or alternatively, you can connect the
load to some other kind of resistive load. Heater elements designed to be used with
220v, may be used, although they are likely to produce less power than their intended
design.
The wind generator comes attached to a long length of flexible cable. This 3 core
cable should be connected to the charge controller 3-way input. The input is not
colour-coded, as it does not matter which way these are connected, as the 3wires bear
AC current
