Installation
Mounting the Charge Controller
The FLEXmax 100 must be mounted upright on a wall or similar flat upright mounting surface. No other
mounting positions are allowed. Installation in shade is recommended.
Two mounting methods are available. The first method uses keyhole slots on the back of the controller for
hanging directly on a wall and flush with the surface. This method is useful for a standalone installation.
Keyhole Slot Mount
Figure 3 Mounting the Charge Controller (keyhole)
To mount using keyhole slots (A):
1. Use two slotted #14 wood screws. The mounting surface must
be strong enough to support the weight of the FLEXmax 100.
NOTE: OutBack is not responsible for damage resulting from
inadequate mounting hardware or preparation.
2. Mark the screw insert locations on the surface as in
B.
Space them according to the keyhole slot locations as in
D.
NOTE: The brackets included with the controller have holes
with the same spacing which can be used as a marking template.
3. Using the appropriate tools, set the screws into the surface.
The heads should protrude by ⅛” (0.3 cm).
4. Hang the FLEXmax 100 by placing
its back against the mounting surface
and aligning the keyhole slots with
the screws. Settle the controller
so that the screws seat in the
narrow end of each slot.
5. Secure the base of the controller
to the surface. Insert two ¼”
hex head lag screws into the
holes shown in
C.
