Step 3 - Mount to a Vertical Surface
CAUTION: Risk of Burns
!
Install the TriStar MPPT 150V in a location that prevents casual contact. The
TriStar MPPT 150V heatsink can become very hot during operation.
M6 Screw
Mounting Hanger
Figure 3-2. Attaching the mounting hanger
1. Attach the mounting hanger to the bottom of the TriStar MPPT 150V with the M6 screw pro-
vided as shown in figure 3-2.
2. Place the TriStar MPPT 150V on a vertical surface protected from direct sun, high tempera-
tures, and water. The TriStar MPPT 150V requires at least 6" (150 mm) of clearance above
and below and at least 1" (25 mm) on each side for proper air flow as shown in figure 3-3
below.

3. Place a mark on the mounting surface at the top of the keyhole.
4. Remove the controller and drill a 3/32" (2.5 mm) hole at the drill mark.
5. Insert a #10 screw (included) into the top pilot hole. Do not tighten the screw completely.
Leave a 1/4" (6 mm) gap between the mounting surface and screw head.
6. Carefully align the keyhole on the TriStar MPPT 150V with the screw head. Slide the
TriStar MPPT 150V down over the keyhole.
7. Check for vertical plumb with a level.
8. Mark two (2) mounting hole locations in the wiring box.
9. Remove the controller and drill 3/32" (2.5 mm) holes at the drill marks.
10. Carefully align the keyhole on the TriStar MPPT 150V with the screw head. Slide the
TriStar MPPT 150V down over the keyhole.
11. The pre-drilled pilot holes should align with the mounting holes in the wiring box. Secure the
controller with two (2) #10 mounting screws.
12. Tighten the keyhole screw.

Switches 2 & 3: System Voltage
Four (4) system voltage configurations are available as shown in the table below:
System Voltage
Auto

48
The "auto" setting allows the TriStar MPPT 150V to detect the system voltage automatically on start
up. The test is only performed at start up and the detected system voltage will never change during
operation.
Generally, it is best to choose a specific system voltage. The auto detect feature should only be used
in situations where the system voltage is unknown ahead of time or in systems where the system volt-
age may change periodically.
