How to Avoid the 6 Most Common Mistakes when Installing

an XL.1

1. DO NOT use the PowerCenter box lugs to connect wiring to the turbine. There

is not enough space for them, so they will rub the tower and eventually develop a

short circuit. Use crimp-type ring lugs.

2. DO use the built-in polarity checker when connecting the battery leads to the

PowerCenter. Connect either battery lead to the Neg. (-) battery terminal on the

PowerCenter, and then touch the other lead to the Polarity Test Point. A green LED

is good, a red LED shows that the polarity is reversed. Do Not connect your test

wire to the Pos. (+) terminal. Use the same procedure when connecting PV to the

PowerCenter. Please note that the Neg. (-) Battery terminal is on the LEFT side,

while the Turb. Neg. (-) terminal is in the RIGHT side.

3. DO NOT install a circuit breaker between the PowerCenter and the battery

bank or DC bus. The original PowerCenter has a circuit breaker for the wind tur-

bine and the new PowerCenter has internal fusing. Using a circuit breaker on the

output of the PowerCenter can allow the PowerCenter to be open-circuited under

high output condition, which can damage the system. If you are using a Trace Pow-

er Panel, Do Not connect the wind turbine to the PV Array Disconnects in the DC

Disconnect Box. Do connect the Bergey PowerCenter to the “top” of one of the Bat-

tery Disconnects (Pos.) and the Grounding Block (Neg.).

4. DO NOT install the wind turbine close to a steep slope or cliff. If the wind can

blow up at an angle as it hits the wind turbine the furling will be hampered and the

turbine will experience excessive loads and vibration. This is most important from

the prevailing wind direction. Try to keep the tower at least two tower heights back

from steep slopes.

5. DO use thimbles on all guy wires and position the lower malleable clip close to

the thimble so that the guy wire “captures” the thimble securely. Not using

thimbles or not securing them can lead to guy failure and tower collapse. Thimbles

are not required on knuckle-end anchors, such as double-eye and triple-eye anc-

hors.

6. DO follow the recommended wire sizes for your wire run from the wind turbine

to the PowerCenter. With the XL.1 oversizing the wire is a bad thing because it will

cause excessively high currents during high winds. Normally, over sizing wire is a

good thing – but not in this case.
