12. Troubleshooting
Problem Symptom
Solution
Insufficient charging
current to the battery
bank when the rotor is
running
Insufficient wind speed,
below the start-up one
(11 KPH, 7 MPH)
Wait for better wind
speed condition
Rotor and/or yaw
bearings within the
break-in period
They requires about
60-100 hrs. of operation
in normal wind speed
(18-20 MPH) before
they are running at
peak efficiency
Rotor shaft gets stuck
and rotates with
difficulty
Rotor bearings
damaged (rusted or
with dust). The bearings
need to be replaced
Stator and rotor
touching together
because of excessive
bearing waste. The
bearings need to be
replaced
Consistent air
turbulence condition
(1)
Change the location
and/or increase the
height of the tower/
mast. Make sure to
install the turbine 25 ft.
(7.6 m) on open ground
or 20 ft. (6m) above
nearby obstructions
The yaw is not moving
360° freely so the
turbine is not pointing
toward the wind
direction
Rotor bearing damaged
(rusted or with dust).
The bearing needs to
be replaced.
The pole/mast is not
standing straight up.
It needs to be in a
perfect vertical position
Generating power at
controlled rpm
This is normal when the
wind speed and/or the
battery bank voltage are
close to their highest
limits. For more details
see the Indicator Light
on the operating status
table. The unit will
resume normal rpm
operation in an automatic
and unattended way.
