How does wire sizing or voltage drop affect the regulation of the wind generator?
Due to the smart controller of the AIR-X, wire size should not have a large effect on the regulation. The AIR-X uses the power lines to sense battery voltage, but before measuring the battery voltage, the AIR-X will momentarily stop charging. This allows the turbine to make a voltage measurement with no line loss in the system. This is an improvement over the AIR 403 which can only measure the battery voltage plus line loss in the system. The voltage measurement routine takes place periodically as the batteries approach the regulation set point. Output is cut for a fraction of a second, and the whole process will not be apparent from the outside. It will not affect the net energy generation of the turbine. At a minimum, the Air X manufacturer, Southwest Windpower, recommends using the wire size listed for your system in section 3.1.2 of the owner’s guide to avoid power transmission losses.
