Nature Power 2000W-48V Marine Grade Wind Turbine (70701) - Manual (Page 19)

The turbine (especially
its tail) is yawing
continuously
Swirling air because
of turbulence
Change the location and/
or increase the height of
the tower/mast. Same as
per (1) above.
Every time the rotor
shaft begins to spin, it
stops suddenly with a
strong brake action
Open circuit in the DC
connection between
the turbine and the
battery bank
Check for loose or open
connections in the
cables. Make sure the
DPDT blade switch is in
the ON position (neither
the open nor the brake
[short circuit] one).
The rotor remains
stopped even with high
wind speed condition
If the Indicator light is
solid red
The battery bank voltage
and/or the internal
temperature of the
turbine have reached
their highest (cut-out)
limit and the turbine
stops. The turbine will
resume normal operation
in an automatic and
unattended way. Wait for
the proper cut-in
threshold or reset the
unit disconnecting and
reconnecting the battery
voltage with the DPDT
switch
If the Indicator light is
off
Make sure the DPDT
switch is not in the Brake
(short circuit) position
There is some
mechanical problem
(rotor shaft bearings,
hub, internal stator and
rotor contact, internal
damage). The unit has to
be inspected
The turbine works at
controlled rpm often,
with the battery bank
voltage below the
normal maximum of
57.2 V
The Indicator Light status
is flashing red
Normal if within the ±7% of
tolerance in the battery
voltage threshold values
shown in the Operating Status
Table.
Excessive voltage drop through
the cables and/or related
connectors. Please check the
proper cable gauge vs. length
as per the cable gauge chart,
the related connectors and the
batteries’ posts
High resistance or loose
connection in the turbine’s
brushes and/or their tracks.
They should be inspected and
cleaned.
