Turbine Operation 

 
The 

LE-600 Turbine

 is based on a simple design for ease of installation and reliable operation. You 

may notice the following behaviour during normal operation: 
 

 

Cut-in  -

  The  turbine  will  not  begin  to  charge  the  batteries  until  the  rotor  is  spinning  at 

approximately 290 RPM.  Whilst  operating below this speed, the turbine 

will be ‘off

-

load’ 

and freewheeling. Once the turbine output voltage becomes equal to the nominal battery 
voltage (at around 290 

RPM), the turbine will come ‘on

-

load’ and begin to deliver current 

to the batteries. During the off-load stages of rotation, the blades will rotate very freely. 
This allows the rotor to build up speed and allows aerodynamic lift to be generated by the 
blades. 

 

 

Normal  Operation  - 

Once  the  rotor  is  spinning  more  than  290  RPM,  current  will  be 

delivered  to  the  batteries.  As  the  rotor  speed  increases,  so  too  will  the  current  and 
voltage. Excessive wind speed may increase the battery voltage to  a high level. Once this 
happens the diversion charge controller will recognise that the battery voltage is too high 
and begin 'dumping' power to the heater module. 

 

 

Charge Regulation -

 Once the charge controller has switched over to the dump load, the 

turbine will no longer be charging the batteries. Instead the power from the turbine will be 
delivered  to  the  dump  load  (usually  a  resistive  heater  element).  The  battery  voltage  will 
begin  to  drop  to  normal  levels  during  the  regulation  period.  Once  the  battery  voltage  is 
back within acceptable limits, the charge controller will switch the turbine output back to 
the  batteries.  Refer  to  the  Charge  Controller  User  Manual  for  specific  operational 
instructions. This arrangement is more effective than stop/starting the turbine incessantly. 

 

 

Shut Down -

 

The run/stop switch should only be used to slow the unit prior to  taking it 

down or tethering the turbine

By activating the stop switch, the output from the cables of 

the turbine are ‘shorted’ together.  This effectively puts an infinite load on the generator 

causing the turbine to stall. When the stop switch is activated, the turbine may still rotate 
slowly during high winds, but the rotor blades will not be able to build up any significant 
speed. It is not recommended that the stop switch is activated whilst the rotor is spinning 
at  high  speed.  This  sudden  braking  action  will  stress  the  blades  and  other  components. 
Only a

ctivate the stop switch during a ‘lull’ when the rotor i

s not spinning excessively fast.  

 

High winds - In certain high wind conditions, the rotor can overcome the electromagnetic 
braking,  which  allows  high  currents  to  be  produced  in  the  stator  coils.  If  this  situation 
occurs with the wind driving the braked alternator for prolonged periods, damage to the 
turbine will occur.  

 

 

High  Winds  -

  Every  effort  has  been  taken  to  ensure  that  the 

LE-600

  will  withstand  the 

forces exerted by strong winds. However, the raw power in high winds is immense and the 
stresses placed upon the turbine are magnified by gusty and turbulent conditions. Where 
possible the turbine should be shut down and tethered in advance of winds of 27m/s (60 
MPH). This will decrease the wear and tear on the machine and will help to avoid a failure. 
Protect  the  turbine  from  extreme  winds  as  you  would  protect  other  items  of  your 
property.  

 

 
Note: Never allow the turbine to run off-load with no connection to a battery bank. Doing so will 
allow open-circuit voltages to be generated by the turbine. These voltages may be dangerous and 
may damage the stator coils within the turbine.
