Electrical Installation 

 
Please refer to Figs 12 - 14 for appropriate generic wiring diagrams. In a battery charging renewable 
energy  system,  there  may  be  different  ways  of  wiring  small  wind  turbines,  photovoltaic  panels, 
charge  controllers  and 

batteries  together.  This  type  of  system  will  often  expand  ‘organically’,  but 

the following guidelines should be followed: 
 

 

Follow  the appropriate  electrical code  - 

The  electrical  wiring of your 

LE-600

 turbine and 

associated electrical systems must be done in accordance with national and local electrical 
codes and regulations.  

 

 

Do not connect the turbine or batteries during the installation -

 Ensure that the turbine is 

not  running  or  connected  to  the  batteries  during  the  installation  or  wiring  process. 
Connect the output cables of the turbine together to prevent the rotor from starting up.  

 

 

Galvanic  corrosion  of  electrical  joints  -

  Try  to  avoid  connections  between  dissimilar 

metals.  For  example,  connecting  copper  and  aluminium  together  will  result  in  galvanic 
corrosion of the connection.  This  will increase the  electrical resistance of the connection 
(wasting energy), and reduce the mechanical integrity of the joint. Where possible, use a 
fluxed solder to make electrical joints. 

 

 

Protect  the  cables  -

  The  power  transmission  cables  must  be  protected  from  mechanical 

damage and fatigue. Run the cables through an approved conduit / trunking. 

 

 

Cable  strain  relief  -

  Prevent  mechanical  strain  on  the  transmission  cables  running  down 

the tower from the turbine. Clip the cables to the inside of the tower. Failure to do this will 
result in excessive mechanical strain on the cable joints within the slip-ring assembly and 
may cause a failure. Cable ties or cable glands are a good way to prevent mechanical strain 
on the cables. 

 

 

‘Earth’

  the  System  -

  The  turbine  tower  should  have  its  own  separate  earth  point.  The 

negative  terminal  of  the  battery  bank  should  also  be  earthed.  This  provides  protection 
against the build-up of static and lightning strikes. The tower should be earthed separately 
with  its  own  ground  rod  if  there  is  a  long  transmission  distance  between  the  tower  and 
batteries. An appropriate surge arrestor could also be used to help prevent damage to the 
battery charging  system during a  lightning strike. Ensure that the earth cables are of the 
same rating as the positive and negative cables. 

 

 

Cable Selection -

 The cable size table should be used to select the minimum sized cable for 

a given transmission distance. Voltage drop in the cable will be improved if a larger cable is 

used. We recommend using ‘Tri

-

Rated’ cable as it should comply with the wiring codes for 

your area. 

 

 

Fuses  -

  The  turbine  and  charging  circuit  should  be  protected  with  a  suitably  rated 

‘slow

-

blow’ DC fuse or DC circuit breaker. Please refer to the tab

le below for the correct 

rating. The fuse or breaker should be positioned between the turbine and batteries (on the 
positive  cable).  If  a  stop  switch  is  used  (recommended)  the  fuse  should  be  positioned 
between the switch and the batteries.
