There are two methods to wire multiple AIR-Xs:
1) Each turbine directly wired to the battery
Each turbine operates as an independent system separate from other
solar panels, gas generators or any other battery charging
sources.. If the turbine has its own fuse, stop switch, and wires,
the turbine is able to individually communicate and charge the
battery or battery bank.
2) Each turbine wired to a bus bar
If you plan to wire two or more turbines to a "bus" and
then run one set of wires from the bus bar to the battery, you can
use each turbine's internal regulator or install an external
regulator. If you use an external regulator, use a diversion style
("dump load") regulator that turns excess power into
heat for heating air or water. When wiring multiple turbines, it's
possible to reduce your wiring costs by using a bus bar system.
Mounting to Tower
The AIR-X is designed to be mounted on a 1-1/2" schedule 40
steel or aluminum pipe (do not use plastic!). The outside diameter
of the pipe should be 1.875" (48 mm). There's a soft coupling
inside the yaw shaft mount that is designed to provide a good,
tight fit and to dampen some of the noise that is transmitted down
the tower. The clamp and soft coupling design will accommodate
small variations in diameter; however, if you use something other
that a 1.5" SCH 40 (48mm) pipe, be certain the unit has a
secure fit prior to installation.
