Morningstar’s TriStar Controller is a three-function, programmable 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.




Highest Reliability, More Power & Better Battery Charging - Large heat sink and conservative design enables operating at full ratings to 60°C. No need to de-rate. Ratings to 60A at 48VDC will handle solar arrays up to 4kW. Connecting battery sense wires and optional remote temperature sensor will improve control accuracy. Constant voltage series PWM algorithm increases battery capacity and life.

Communications, Electronic Protections & Simple Mechanical Interface - RS-232 connects to a personal computer for custom settings, data logging and remote monitoring and control. Low Telecom Noise: DIP switch setting will change PWM to "On-Off" battery charging. 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.

Fully Adjustable, Easy to Reset & Better Information - DIP switch provides user with a choice of 7 different digital presets and custom settings via RS-232. Pushbutton provides manual reset and stop/start battery equalization or load disconnect. 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.
