Step Diversion Charge Control
1. Remove the access cover
2. Mount the TriStar using the enclosed template.
3. Adjust the 8 switches in the DIP switch. Each switch must be in the
correct position.
4. Attach the RTS if battery charging will be temperature compensated.
5. Connect battery voltage sense wires (recommended).
6. Connect the battery power wires to the TriStar. Then connect the
diversion load wires.

2.3 Installation Steps
The TriStar controller must be installed properly and in accordance with the
local and national electrical codes. It is also important that the installation be
done safely, correctly and completely to realize all the benefits that the TriStar
can provide for your solar system.
Refer to Sections 4.0 and 9.0 for information about the TriStar’s standard battery
charging programs and general charging needs for different battery types. Refer
to Section 5.0 for load control information, and Section 6.0 for diversion.
Recommended tools:
• wire cutter • phillips screwdrivers • wire stripper
• torque wrench (to 50 in-lb) • slotted screw drivers • flashlight
Before starting the installation, review these safety notes:
• Do not exceed a battery voltage of 48V nominal (24 cells). Do not use a
battery less than 12V (6 cells).
• Do not connect a solar input greater than a nominal 48V array for battery
charging. Never exceed a Voc (open-circuit voltage) of 125V.
• Charge only 12, 24, or 48 volt lead-acid batteries when using the standard
battery charging programs in the TriStar.
• Verify the nominal charging voltage is the same as the nominal
battery voltage.
• Do not install a TriStar in a sealed compartment with batteries.
• Never open the TriStar access cover unless both the solar and battery
power has been disconnected.
• Never allow the solar array to be connected to the TriStar with the battery
disconnected. This can be a dangerous condition with high open-circuit
solar voltages present at the terminals.
Follow the installation steps in order: #1 through #8
Step 1 - Remove the Cover
Remove the 4 screws in the front cover. Lift the cover until the top edge
clears the heat sink, and set it aside. If an LCD meter display is attached
to the cover, disconnect the RJ-11 connector at the meter for access.
CAUTION: Do not remove the cover if power is present at any of the terminals. Verify
that all power sources to the controller are disconnected.
PRUDENCE : N’enlevez pas le couvercle en cas de tension à une des bornes. Vérifiez
que toutes les sources d’alimentation au contrôleur sont déconnectées.
Step 2 - Mounting
Locate the TriStar on a wall protected from direct sun, high temperatures, and
water. Do not install in a confined area where battery gasses can accumulate.
NOTE: When mounting the TriStar, make sure the air flow around the controller and
heat sink is not obstructed. There should be open space above and below the heat
sink, and at least 75 mm (3 inches) clearance around the heat sink to allow free air
