Before continuing with the install, click the mode
selector button to stop the turbine, and prevent
the dump load from being energized.
Step 5:
Connect PV leads. Please ensure that the PV
leads are connected with the proper polarity. The
system will not operate correctly and could be
damaged if the polarity is reversed. First connect
the PV negative wire to the terminal marked “PV-“,
then touch the PV positive wire to the “POLARITY
CHECK” pad on the controller, the green LED
should light, if it does, connect the PV positive
wire to the “PV +” terminal. If the red LED lights,
stop and double-check everything for reverse po-
larity.
The LED indicating that the PV is charging will
light in a few seconds assuming that there is suffi-
cient sunlight.
The maximum current capacity of the PV regulator
circuit on the PowerCenter is 30 amps. However,
please note that PV modules can exceed their
rated power under some conditions and we do not
recommend connecting more than 750 Watts of
PV to the PowerCenter.
Caution
Over sizing the PV array will damage
the PowerCenter and void the warranty
coverage.
Make sure that PV panels have blocking diodes
(Schottky diodes) installed to prevent reverse cur-
rent flow through the panel.
Step 6:
Connect Inverter. If the system includes a DC to
AC inverter, connect the inverter input leads to the
battery terminals or DC source center, not to the
PowerCenter. The PowerCenter circuit board is
not designed to handle the high currents that are
possible with inverters. Make sure that there is a
fuse between the batteries or DC bus and the in-
verter.
Step 7:
Connect Loads. If the system includes 24 VDC
loads, connect them to the battery terminals or DC
source center. Do not connect them directly to
the PowerCenter.
Step 8:
Click the mode selector button to release the tur-
bine, and begin operating the turbine.
The XL.1 wind turbine system is now ready to op-
erate. We recommend that you verify that the
XL.1 is producing power by putting the PowerCen-
ter in Watt Display mode (see Page 7). In all but
the lightest of winds, you should see indication of
varying wattage coming from the wind turbine.
8. Inspections and Maintenance
The BWC XL.1 installation should be inspected
after 30 days and then again 180 days after instal-
lation. Following these two inspections the instal-
lation should be inspected every two years and
after any particularly severe weather. In corrosive
marine environments more frequent inspections
are recommended. Inspections should be done
on days when the wind is below 7 m/s (16 mph).
Check List for Inspections
1. Inspect each of the anchor points. Ensure
that all hardware is secure and the guy wires
are properly tensioned. Check to ensure that
no strands are broken.
2. Stop the alternator by clicking the mode selec-
tor button to place the PowerCenter into Stop
Mode. Once the rotor is stopped, climb or
lower the tower. Always use proper safety
belts and lanyards when climbing.
Warning
Only qualified personnel with proper
safety equipment should climb the
tower. Never climb the tower when
the rotor is turning.
3. Inspect the blades for:
A. Condition of the leading edge, particular-
ly out near the tip. board of the pitch weight.
B. Tip damage.
