Morningstar TriStar TS 45 12/24/48 Volt 45 Amp Solar Charge Controller


Morningstar TriStar TS 45 12/24/48 Volt 45 Amp Solar Charge 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 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 ETL Listed (UL1741) and TUV (IEC62109-1), and is designed for home systems and professional applications.


  • High Reliability - Large heat sink and conservative design enables operating at full ratings to 60°C. No need to de-rate.
  • 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 settings via RS-232.
  • Extensive Electronic Protections - 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 power panels.
  • Better Battery Charging - Connecting battery sense wires and optional remote temperature sensor will improve control accuracy. Constant voltage series PWM algorithm increases battery 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 11 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.
