The recommended wire size for the generator seems small for 400 Watts output. Why is that?
Because the output of the AIR-X follows the cubic power in the wind, the output increases rapidly with increasing wind speed until over-speed stall occurs and the output power drops off to about 75 watts. The wiring could be sized for the maximum current output of the turbine, but this output is seen primarily in gusty conditions. We have recommended wire sizes that are intentionally small to save the customer from spending a lot of money on wiring, while still experiencing no more than a 5% annual energy loss due to resistive line losses. In most cases this will be acceptable for local electric codes please contact your installer or local electrician to be certain of your area’s specific requirement.
