Please note: The TS-M-2 Digital Display shown in the product photo is sold separately.


Morningstar's TriStar-45 Controller is a three function controller that provides reliable solar battery charging, load control or load diversion regulation. This controller operates in only one of these modes at a time but, two or more controllers may be used to provide multiple functions. The TriStar-45 uses advanced technology and automated production to provide exciting new features at a competitive cost.

The TriStar-45 is UL listed and is designed for both solar home systems and industrial applications.

Optional: Morningstar's Remote Temperature Sensor (RTS) provides very accurate battery charging in solar systems that experience temperature variations during the year. Use with the TriStar for battery charging or diversion control modes (not for load control mode) whenever the temperature of the battery varies more than 5°C (9°F) during the year. When used with the TriStar™ controller (no on-board temperature compensation), the RTS adjusts charging for temperature changes at the battery.
