Positive Battery Cable Connections
CAUTION:
Equipment Damage
When connecting cables
from the Radian inverter
to the battery terminals,
make sure to observe
the proper polarity.
Connecting the cables
incorrectly can damage
or destroy the equipment
and void the product
warranty.
Ensure the mounting surface is strong enough to handle 3 times the total weight of all the components. Add plywood or other
reinforcing material as necessary to strengthen the surface.
Attach the wall bracket. Center the mounting holes on the wall studs. Use all 6 mounting screws to secure the bracket.
Lift the inverter so that the inverter bracket is above the wall bracket.
Lower the inverter so that the inverter bracket slips into the wall bracket.
If GSLC is not used:
Secure the inverter to the surface using a minimum of 1 wall screw (or appropriate hardware).
If GSLC is used
: Unscrew the inverter bottom screws approximately ¼” (0.6 cm) to 3/16" (0.5 cm).
Align the GSLC along the bottom of the inverter. Slide the bottom screws into the keyhole slots.
Mark the spots for the GSLC mounting feet. (If necessary, remove the GSLC to install wall anchors.) Install screws to secure the feet.
Follow the appropriate instructions for installing other components. Different mounting locations are available.

The FLEXmax charge
controller is mounted
with the FW-CCB bracket.
The FW-CCB2 allows two
controllers side by side (using
the forward holes to allow for
conduit.)
The Radian has two sets of
bracket positions. The GSLC
has one set.
NOTE:
The FLEXmax
Extreme charge controller
attaches directly to the wall,
not the Radian system.
It does not use
OutBack brackets.

The Radian allows two locations
for the MATE3 mounting bracket
(FW-MB3).
The Radian has one
mounting location for the
HUB product. The GSLC
also has one location.
