Installation
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 gure 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 ow as shown in gure 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.
Step 4 - Adjust Settings Switches
Switch 1: Reserved for Future Use
Settings switch 1 should remain in the “OFF” position.
Mode Switch 1
Solar Charging OFF
future use ON
Switches 2 & 3: System Voltage
Four (4) system voltage congurations are available as shown in the table below:
System Voltage Switch 2 Switch 3
Auto OFF OFF
12 OFF ON
24 ON OFF
48 ON ON
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 specic 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 voltage may change periodically.
