Please study the following section before commencing installation. This information is provided to
ensure your safety during installation, operation, and in case of future maintenance. Please contact
us if you have any further questions.
Due to the nature of small wind turbines such as the Hyland 920, there are a number of potential
mechanical and electrical hazards as follows.
Safety instructions
Maintain a safe distance from the wind turbine during operation.
The primary mechanical danger of the Hyland 920 are the rotating blades. The blades are made
from a strong injection moulded carbon fibre composite material with sharp leading and trailing
edges. These rotating blades can cause injuries, even at low speeds. Caution must also be taken
when unboxing or handling the turbine during installation
• Never attempt to touch spinning blades.
• Never attempt to slow or stop spinning blades in any way other than with the controller.
In the event of extreme weather conditions, it is possible for foreign objects to strike the blades and
cause blade fragments to become projectiles. The inclusion of the shrouded diuser in the Hyland
920 design significantly increases safety during such events.
Australian Standards (AS4024) dictate that turbine must be placed out of reach of personnel. This
means at least 2.7m above any platform below the turbine. In the event that work is to be carried
out closer to the turbine, then it must be isolated by applying the short and work cannot commence
above 40 km/h wind speeds.
Mechanical dangers
A breaker should always be installed between the battery and controller to allow electrical isolation.
Never work on the controller wiring without the battery being isolated. Batteries have strong short
circuit currents so live work is dangerous.
The generator will produce open circuit voltages during operation if the electrical connection to the
battery or load are interrupted. Please ensure the turbine is not in operation before commencing
work. Always apply the brake to “short” and isolate from the battery before commencing any work
on the controller
Charging currents produced by the Hyland 920 can reach up to 22 A during operation. Please
ensure that all electrical wires and components are rated as specified in wiring specifications.
The diversion resistor can become extremely hot in high wind conditions as it acts as a brake to slow
the blade rpm. Please ensure that the diversion resistor is appropriately sited with adequate space
and ventilation. Do not site the diversion resistor close to flammable materials.
Electrical dangers

Only work on the Hyland 920 during appropriate weather conditions to prevent injury of personnel.
Do not stand under unsecured objects during installation.
Please ensure all batteries are disconnected from the system prior to conducting work, and the
Turbine is connected to the controller with it switched to ‘short’ to prevent the blades from spinning.

maintenance

Wind turbine power generation has a cubic relationship with the inlet wind speed. This means if
the wind speed is doubled, the produced power increases by a factor of 8. The power curve of the
Hyland 920 is presented below. The Hyland 920 wind turbine system includes a Diuse Energy
maximum power point tracking (MPPT) controller that optimises the amount of power extracted for
a given wind speed. For wind speeds beyond 18 m/s (65 kmh) the controller is designed to reduce
the rotor speed to limit the power output to 1 kW and prevent the damage of electrical systems.
Power curve
Also note that when the battery is in a high state of charge the boost circuit of the turbine controller
is limited to 10A. The full current applies when the turbine voltage reaches the battery voltage
The following section outlines the installation procedure for the Hyland 920 wind turbine.
Telecommunications tower installation
1. Unpack turbine and check that all components are present. Note that the turbine is
preassembled and checked prior to delivery.
2. Feed the system 3 core power cable (recommend 12 AWG) through the mounting pole. The
turbine is designed to be mounted on a length of 40 NB (48.3 mm OD) Galvanised Pipe.
3. Attach the Hyland 920 power cable to the system power cable.
4. Insert the yaw mechanism base onto the mounting pole, ensuring that it is fully inserted.
5. Tighten the hose clamp on the base to approximately 4 Nm.
6. Loop a cable tie around the vertical diuser support and one of the blades. This will prevent the
blades from spinning during installation.
7. Install lifting lug to either top support thread or two side support threads. See image below.
8. Hoist turbine up tower using site preferred method.

9. Mount pole in desired location ensuring the pole is vertical. This is very important to ensure the
turbine yaw operates correctly.
10. Secure cabling at the base of the pole with a 1 m loop(s) to allow later removal of the turbine
from the pole if necessary and allow turbine to yaw freely.
11. Run cabling to the controller and connect the three phases of the turbine power to the
controller.
12. Connect the two phases of the output to the battery through a breaker switch. Set the breaker
to ‘o’.
13. On the turbine controller set the SHORT/RUN switch to SHORT. See image below.
14. Remove the cable tie from the Turbine.
15. Turn the battery breaker to ‘on’.
16. On the turbine controller set the SHORT/RUN switch to RUN.
17. Assuming there is wind - the MPPT controller will now power up.
Note: The controller will not be active without turbine power.
Note: See following ‘Hyland 920 Controller User Manual’ for controller setup instructions.

Please refer to the Hyland 920 controller operation guidelines for information on ‘starting’ and
‘stopping’ turbine operation, and operation during high wind conditions.
Operation Guidelines
The turbine can be slowed by switching the brake on, this will stop it in light wind conditions or
significantly reduce power in medium winds
The turbine can be brought to a very slow rotation by switching the short button. This shorts the
windings in the generator and applies the maximum braking torque and has been tested to over 100
km/h.
Start and stop
The Hyland 920 turbine has been mechanically designed to withstand severe winds. The controller
can withstand a 22A throughput, however the plugs and cabling are rated to 20A and we
recommend a 20A breaker. If possible, the turbine should be put in the short position if it is known
that severe wind events are expected. For remote area operation we can supply an automated
system that will protect the controller. For details contact us.
NB: By March 2021 the high wind protection will be integral to the controller, it will cause the turbine
to shut down at ~75km/h.
High wind conditions
There are no maintainable components on the Hyland 920 wind turbine. Diuse Energy
recommends a visual inspection after severe weather events to ensure there is no damage caused
by objects impacting the turbine. In the event that the turbine is underperforming or ‘noisy’ – a more
thorough inspection should also be completed.
Other than damage by storms, the other components that can fail are the rotor and yaw bearings,
they are designed for a 100,000 hour life (maximum for sealed bearings). If your turbine suers a
failed bearing, contact Valen for assistance.
In the event of underperforming or damaged components - please refer to the ‘Trouble Shooting’
section or contact us at [e-mail]
