TriStar 45 amp multi-function controller




tell me more

Morningstar's most advanced product, the TriStar, is a three-function controller that provides reliable solar battery charging, load control or diversion regulation.

Can function as either a solar regulator, load controller or diversion load regulator. Two or more controllers may be used to provide multiple functions.

As a solar battery charger, it implements an efficient 4-stage charging process to increase both battery capacity and life. It can be used with large solar arrays up to 1260W at 24V.

As a load controller, it can start large loads such as motors and pumps without damage to the system, allowing inrush current to 200A. It protects against short-circuiting and overloading with automatic reconnect.

As a diversion load regulator, it protects against battery overcharge, diverting excess energy to a secondary battery or alternate DC resistive load such as an immersion heater.

This model is for use with currents up to 45A. We also sell the 60A model for use with larger systems.

A special COM connection allows full data logging via a PC (click here to download software).

For greater charging efficiency, particularly when battery temperature varies by more than 5C throughout the day/year, add a Morningstar remote temperature sensor.
