Air X Owner’s Manual
27
The Air X internal voltage regulator cannot be completely turned off; how-
ever, by setting the voltage regulation set-point to its highest value (poten-
tiometer turned completely clockwise), the Air X internal regulator may be
virtually eliminated from the battery charging system.
If a charge controller other than the Air X internal controller is utilized, it
must be a diversion style regulator. A diversion style regulator charges
the batteries, and as the batteries become charged, the excess power is
diverted to a resistive load. This technique allows for the capture of full
turbine power even after the batteries are charged. Diversion controller
and load should be sized 1.5 times larger than the turbine(s) maximum
rated output.
Do not use a pulse width modulated (PWM) or shunt style controller wired
between the Air X and battery bank; Air X is not designed to work with
these types of controllers. Additionally, most controllers designed to work
with solar panels are not suitable for use with Air X. These controllers
“disconnect” the solar panels – or in this case Air X – from the battery
bank when the batteries are charged, allowing Air X to spin free, which is
not recommended.
Eight - Air X Maintenance
Although your Air X has been designed to run for long periods without
requiring any maintenance, reliability and performance will be enhanced if
you periodically inspect your system.
After one month and every six months thereafter:
• Che
ck blades for chips or nicks. Replace blades if damaged. Do not
operate the turbine with chipped or unbalanced blades. This can cause
severe wear, damage, and possible failure. Do not install individual blades.
The blades are balanced as sets.
• Che
ck the blade bolts and the hub nut for tightness.
• Che
ck nosecone for cracks and proper fit.
•
Wash off any built-up dirt or debris from the blades.
• Che
ck all electrical connections to make sure they are tight and free
from corrosion.
• As with all
charging systems, check your battery water levels and add
distilled water in accordance with manufacturer’s recommendation.
•
ower suggests replacing the blades and bearings every
five years for optimal performance.
CAUTION:
Never approach the turbine during operation.
• Check
yaw clamp screws for proper torque (see section 6-2).
