Bergey 24 VDC B, Owner'S Manual

11 

The PowerCenter has a limited current carrying 
capacity so we recommend that you use a DC 
Source Center whenever you have multiple XL.1 
wind turbines.  DC Source Centers are available 
from Bergey Windpower. 
 
Additional Design Guidance: 
 

1.  If you have multiple XL.1 turbines and 

PowerCenters, do not connect more than 
one wind turbine to one PowerCenter. 

2.  Connect multiple PowerCenters to a DC 

Source Center via the PowerCenter’s bat-
tery terminals. 

3.  Do not connect the PowerCenter to an-

other controller that could disconnect the 
PowerCenter from the batteries.  The 
PowerCenter should not be disconnected 
from the battery when there is input from 
the wind turbine.  

B.  Location

The PowerCenter must be installed indoors and 
should be located relatively close to the battery 
bank.  Do not install the PowerCenter outdoors; it 
is not waterproof. 
 

C.  Mounting:

The PowerCenter needs to be mounted vertically 
to a wall, or other support structure, so that air can 
pass unobstructed through the passive cooling 
channel behind the enclosure.  We recommend 
setting the height of the LED’s at eye level if pos-
sible so that the system status lights will be easi-
est to read.  
 
The enclosure dimensions and mounting layout 
for the PowerCenter are shown in Figure 12.  The 
PowerCenter should be mounted with four M4 
(0.157” dia.) screws.  We recommend the follow-
ing procedure: 
 
Tools Required: 
 Pencil 
 Carpenters 

level 

Drill with ~ 2 mm or 0.09” dia. drill bit 

(4) M4, 1/8”, or 5/32” screws 

 Screwdriver 
 
Procedure: 
 

Step 1: 

Mark the mounting hole locations using the Pow-
erCenter enclosure as the template.  Use a car-

penters level to check the levelness of the enclo-
sure before marking the holes.   
 

Step 2: 

Drill small (~ 2.5 mm or 0.1 in diameter) pilot holes 
for the mounting screws. 
 

Step 3: 

Screw the top two mounting fasteners into the wall 
until ~ 6 mm (1/4”) of the shank extends out from 
the wall. 
  

Step 4: 

Remove the PowerCenter cover and place the 
PowerCenter enclosure on the two upper mount-
ing fasteners.  Slide the enclosure down such that 
the fasteners are placed at the top of the inverted 
“T-slots”.
