Tri-Star three-function solar controller.

Morningstar's TriStar Controller is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. The controller operates in one of these modes at a time and two or more controllers may be used to provide multiple functions.

The TriStar used advanced technology and automated production to provide exciting new features at a competitive cost. The optional TriStar meter is the most sophisticated and informative controller meter on the market. The controller is UL listed and is designed for both solar home systems and professional applications.

Charge Control
Load Control
Diversion Control
Constant voltage series PWM design to provide highly efficient battery charging. Starts large loads including motors and pumps with no damage to controlelr. May be used for solar, wind or hydroelectric.
4-stage charging to increase battery capacity and life. Allows inrush current to 300A. Excess energy is diverted from primary battery to a secondary battery or alternate DC resistive load.
Parallel for larger solar arrays up to 300A or more. Electronic short circuit and overload protection with automatic reconnect. PWM reduces power into diversion load during overcurent conditions.
   
Key features and benefits
Highest reliability
  Large heatsink and conservative design enables operating at full ratings to 45°C. No nead to derate.
More power
  Ratings to 60A at 48VDC will handle solar arrays up to 4kW
Communications capability
  RS-232 connects to a personal computer for custom settings, data logging and remote monitoring and control.
Fully adjustable
  DIP switch provides user with a choice of 7 different digital presets and custom setting via RS-232
Extensive electronic protection
  Fully protected against reverse polarity, short circuit, overcurrent, high temperature and overvoltage
Simple mechanical interface
  Larger power terminals and conduit knockouts. Extra space for wire turns. Fits on Xantrex power panels.
Better battery charging
  Connecting battery sense wires and optional remote temperature sensor will improve control accuracy. Constant voltage series PWM algorithm increases batetry capacity and life.
More information
  3 LED's to indicate status, faults and alarms. Optional meter displays extensive system and controller information, automatic self-test and reset capabilities. Meter connection via RJ-11 phone jack.
Easy to reset
  Pushbutton provides manual reset and stop/start battery equalization or load disconnect.
Low telecom noise
  DIP switch setting will change PWM to "On-Off" battery charging.
