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™ uses 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.

Product Features

• Large heat sink and conservative design enables operating at full ratings to 45 °C. No need to derate.
• Ratings to 60 A at 48 V DC will handle solar arrays up to 4 kW.
• RS-232 connects to a personal computer for custom settings, data logging and remote monitoring and control.
• DIP switch provides user with a choice of 7 different digital presets and custom settings via RS-232.
• Fully protected against reverse polarity, short circuit, overcurrent, high temperature and overvoltage.
• Larger power terminals and conduit knockouts. Extra space for wire turns. Fits on power panels.
• Connecting battery sense wires and optional remote temperature sensor will improve control accuracy. Constant voltage series PWM algorithm increases battery capacity and life.
• 3 LEDs 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.
• Pushbutton provides manual reset and stop/start battery equalization or load disconnect.
• DIP switch setting will change PWM to ”On-Off” battery charging.

TriStar™ Options

• TriStar™ Meter: 2 x 16 display mounts to controller and provides system and controller information, data logging, bar graphs and choice of 5 languages.
• TriStar™ Remote Meter: Includes 98.4 ft (30 m) of cable for mounting meter away from the controller.
• Remote Temperature Sensor: Provides temperature compensated charging by measuring temperature at the battery (32.8 ft/10 m cable).
