3.3.1.1

 

Low temperature operation 

Plastic materials do not perform well in extreme cold, becoming brittle and breaking. This applies to wind 
turbine  blades,  whether  glass  filled  or  not.  Operation  at  around  0°C  should  not  be  a  problem,  but  most 
materials  are  vulnerable  at 

–20°C  and cannot be  warranted to survive indefinitely. Ampair‟s glass filled 

polyester blades are superior to nylon, carbon polymer or other plastics in this respect. However, when ice 
factors are also considered, the prediction of blade reliability is even more difficult. 

Other materials are also suspect. For this reason Ampair uses Neoprene components where possible and 
"Arctic"  grade  PVC  cables.  Grease  used  in  sealed  bearings  allows  performance  to 

–

30°C  or  below,  but 

component  tolerances  (ball  and  ring)  can  lead  to  greater  friction  and  increased  wear  causing  reduced 
bearing life. 

3.3.2  The rectifier 

It is best to transmit electrical power as AC at as high a voltage and as low a current as possible so as to 
minimise losses due to the resistance of the wiring system. For this reason the rectifier of the Pacific 300 
is  not  fitted  inside  the  generator  but  is  instead  supplied  as  a  separate  unit  for  fitting  adjacent  to  the 
regulator and or battery. The rectifier is a three way bridge rectifier mounted on a heat sink. 

3.3.3  Other system components 

The basic wind turbine package only consists of the generator and rectifier. The other components which 
can be linked together in a modular manner are described elsewhere in this manual. 

4  INSTALLATION 

4.1  Installation sequence 

A lot of problems can be prevented if the following sequence is adhered to: 

1. First check that your order is complete and undamaged, and that you have received the correct 
voltage generator (12 or 24 volt). See the packing lists below to assist in this. 

2. Gather your tool kit. See tool list below. 

3. Plan your installation. See guidance notes below. 

4. Mechanically install the mounting system. 

5.  Run  the  electrical  wiring  and  mechanically  mount  any  accessories  (including  the  rectifiers  on 
their heatsink) but do not connect to the batteries. 

6. Mechanically install the wind turbine generator, and then electrically connect it. 

7. Connect to the batteries. 

8. Check correct operation & installation.
