Morningstar TriStar solar controller TS45

Morningstar's most advanced product, the TriStar, is a three-function controller that provides reliable solar battery charging, load control or diversion regulation and is capable of handling solar arrays up to 4kW.

It operates in one mode at a time, as either a solar battery charger, load controller or 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 300A or more. As a load controller, it can start large loads such as motors and pumps without damage to the system, allowing inrush current to 2--A. It protects against short-circuiting and overloading with automatic reconnect. As a regulator, it protects against battery overcharge, diverting excess energy to a secondary battery or alternate DC resistive load.

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