Mounting for System Components
For the FLEXmax charge controller: 
To fit on the Radian inverter’s right side, the FLEXmax 
charge controllers require the FW-CCB or FW-CCB2
mounting brackets. To accommodate many possible
mounting requirements, four sets of mounting holes
have been provided for the brackets.
For the MATE3:
To fit on the Radian inverter’s
left side, the MATE3 requires 
the FW-MB3 mounting 
bracket. Holes are provided on
the upper and lower left side
to attach the FW-MB3. For
more information, see the
FW-MB3 instruction sheet.
For the HUB:
To fit on the Radian inverter’s left side,
the HUB uses two mounting holes and
three knockouts.
The top of the GS Load Center (GSLC) connects to the bottom of
the Radian inverter using four keyhole slots. The keyhole slots fit
over four screws on the bottom of the inverter that will secure
the GSLC to the inverter when they are tightened. 
(The long screwdriver recommended on page 18 may 
be needed to reach these screws.) The GSLC should be
secured to the wall using screws or wall anchors. The
GSLC also makes a mechanical connection to the Radian
using bus bars that bolt to the inverter’s DC terminals. Other 
connections are wired as necessary. For more information on 
these connections, see the GS Load Center Installation Manual. 
Several system components can mount directly onto the Radian 
inverter or the GSLC. The MATE3 System Display and the HUB
Communications Manager can easily be mounted on the left side 
of the system. Up to two FLEXmax 60 or 80 charge controllers can 
be mounted on its right side. 
NOTE: The FLEXmax controller requires mounting brackets 
(see below). The conduit provided with these brackets is long
enough to wire the FLEXmax directly to the GSLC. Additional
conduit may be necessary when mounting on the inverter. The 
image on the right shows GSLC mounting. See Figure 2 on page 
12 for other configurations.
NOTE: The OutBack FLEXmax Extreme should be installed on the wall to either side of the GSLC 
for direct wiring access and does not require additional brackets.
