Diagram #2 (applicable for 48V nominal battery systems)
IMPORTANT:
This is not intended to be a complete system diagram; fusing, discon-
nects, and grounding should comply with local electric codes.
Notes:
One TriStar provides charge control, while a second TriStar provides lighting timing control.•
The TriStar providing lighting control uses the Array Voltage to determine daytime/nighttime. It senses the •
Array Voltage via its Sense +/- terminal pair.
Because of the high Array Voltage present in 48V systems, a resistive voltage divider is used to reduce this •
voltage to a level the TriStar can handle on its Sense terminals.
For detailed installation information, please consult the respective product manuals (TriStar).•

Resistors (R) should be at least
10K, ¼ W each .
Sunrise and Sunset thresholds for
the lighting TriStar can be adjusted
according to R used. For basic
operation, use equal value R.
