The second mounting method uses brackets on the top and bottom of the controller. This method is useful
when mounting the controller next to an OutBack inverter system, as the conduit openings will align. It is also
useful for mounting without making advance measurements. The FLEXmax Extreme controller comes with two
identical brackets.
Figure 4 Mounting the Charge Controller (brackets)
To mount using brackets:
1. Using two ¼” hex head lag screws, mount the lower
bracket with the tabs facing upward. The mounting
surface must be strong enough to support the added
weight of the FLEXmax Extreme.
NOTE : OutBack is not responsible for damage
resulting from inadequate mounting preparation.
2. Lower the FLEXmax Extreme onto the bracket as
shown to the left. The bracket tabs can be inserted in
one of two positions: forward or rear.
 To mount the controller flush against the wall,
insert the tabs in the forward slots as shown below.
 To mount the controller 0.83” (2.1 cm) from the
wall to align with an OutBack mounting plate,
insert the tabs in the rear slots as shown below.
NOTE: The charge controller can rest on the lower
bracket for the rest of the procedure, although it will
need at least one hand to steady it.
3. Insert the upper bracket into the same set of slots as
were used with the lower bracket (forward or rear) as
shown to the left.
4. Using two ¼” hex head lag screws, attach the upper
bracket to the mounting surface as shown to the left.
Mounting is complete. Proceed to charge controller
wiring or other installation steps.
