If the PowerCenter cannot stop or slow the turbine
after 3 minutes, it will return to normal operation.
During the following 5 minutes, the PowerCenter
will not allow another attempt to stop the turbine
or enter manual Slow Mode.
To release the wind turbine from stop mode click
the Mode Selector Button.
Battery Equalization:
Equalization is a maintenance function that brings
the batteries up to a higher state of charge and
causes them to out-gas (bubble) actively. It
should be performed approximately once a month
on a windy day.
The PowerCenter has an automatic five-hour bat-
tery equalization function that is initiated using the
push button on the backside of the PowerCenter
enclosure. Press and hold the mode selector but-
ton until the battery voltage LED’s begin blinking
and release the button. When the equalization
function is activated the regulation voltage is
raised by 2 VDC (30.1 VDC is the factory setting
for equalization). During equalization the voltage
indicating LED’s will blink.
To manually exit equalize mode click the Mode
Selector Button.
Note
Equalization will allow the battery bank
to reach 30 VDC, which may cause
some inverters to shutdown due to “in-
put over voltage”.
Caution
Do not equalize sealed batteries. The
out-gassing at high battery voltages will
damage them.
Always check the electrolyte levels in each battery
cell after equalization and add distilled water as
necessary. Do not add battery acid. The loss of
fluid is due to water being dissociated into hydro-
gen and oxygen. The sulfuric acid remains. The
production of potentially explosive hydrogen gas
during hard charging is the reason that battery
enclosures should always be ventilated.
Manual Slow Mode:
Normal operation can be overridden and the tur-
bine forced to operate very slowly, but still pro-
duce some power using the manual Slow-Mode
function. To select this mode press and hold the
mode selector button until the Slow-Mode LED
begins blinking slowly and release. To exit Slow-
Mode, press (click) the Mode Selector Button.
To manually exit manual or automatic Slow Mode,
click the Mode Selector Button. You must use the
Mode Selector Button to manually exit manual
Slow Mode; it will not exit automatically, even if
the battery voltage drops significantly.
Watt Display:
To display instantaneous turbine power output,
press and hold the mode selector button until the
Battery Bank Status LED’s begin ramping up and
down, and then release the button. You will need
to hold the selector button for about 30 seconds
before the PowerCenter cycles to this function.
After releasing the button instantaneous turbine
output power is displayed. Each LED indicates
100 watts; so 5 LED’s indicate 500 watts. To exit
watt mode, click the mode selector button.
To manually exit watt display mode click the Mode
Selector Button.
Blown Fuse Mode
This is an automatic mode that the PowerCenter
enters to protect itself if it detects that the main
90-amp fuse has blown or the battery bank has
been disconnected. In this mode the turbine will
turn slowly (as if in Slow Mode) and the Slow
Mode LED will blink at the same rate as the Wind
Turbine LED.
To restart the system from this protective mode
you will need to click the Mode Selector Button. It
will not automatically reset itself. Before manually
resetting the system, however, you need to check
the 90-amp fuse and the electrical connections to
the battery bank. See Page 17 for information on
replacement fuses.
The PowerCenter senses a lost battery problem
by monitoring the system voltage. It is possible to
