13. lation Choose the wire size that is suggested for the size of turbine electrical current and the distance from the turbine to the charge controller Good wire connections are absolutely essential to avoid poor power delivery and high temperatures at the connection All electrical systems lose energy because cables have a resistance The mounting structure must be directly earthed for lightning The power cable is usually brought down the inside of the mounting structure to give some protection Supply cables should never be spanned or suspended from the turbine structure and should be buried at least one half metre deep in a suitable plastic or steel conduit 5 2 Lightning protection Proper grounding is essential to protect the system from induced voltages and static The installation must comply with local requirements for electrical installations Ensure that the generator is electrically connected to the mounting structure and that the structure is earthed This is usually done by burying a 2 to 3m 6 10 length of water pipe steel or copper horizontally 800mm 2 5 below the ground surface A good connection is made between the middle of the pipe and the structure An improved method is to bury a cross of pipe which requires an X shape to be excavated The connection is made in the centre of the cross The negative battery connection should also be grounded using a ground point close to the battery The wire size for grounding shou
