3.1.2 Wire Size
To select the appropriate size wire, measure the distance from the batteries to your
BSG ,
then refer to the following wire sizing chart as
minimum
sizes. If cost is not an
issue, a larger sized wire will improve the performance of your
BSG .
We recommend these as the
minimal
wire sizes; for optimal performance you should use the
largest wires that are practical and affordable. Local, state, and national electrical codes
can substitute these recommendations, and should be followed to insure the safety of
your system..

Wiring Resistance and Regulation
Depending on your exact system configuration including other charging sources in your
system, wiring resistance may affect the regulation set point of the turbine. Higher
wiring resistance (smaller wires) will tend to lower the voltage at which the turbine enters
regulation and stops charging. The recommended wiring sizes should provide little effect
on the regulation set point, but all installations should be observed over time to ensure
that the batteries are charged to the proper voltage.
3.1.3 Grounding/Lightning Protection
Properly grounding the turbine is very important in protecting the electronics for
long-term operation. Grounding procedures must be followed along with any local electrical
codes.
IMPORTANT: SEVERE TURBINE DAMAGE CAN RESULT FROM IMPROPER
GROUNDING! FAILURE TO PROPERLY GROUND WILL VOID YOUR WARRANTY.
It is very important to ground your battery bank and ground your tower for lightning and static
protection. Proper grounding also enhances the safety of your turbine system. The
green lead wire provides grounding for the body of the turbine. This wire must be
connected to the system earth ground. This is usually done by connecting a wire from a
ground rod near the base of the tower to the green turbine lead wire. For additional
lightning and static protection, another wire should connect this ground rod to the tower pipe.
