Tristar 12/24/48V PWM 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 UL listed and is designed for both solar home systems and professional applications.
Key Features and Benefits
Large heat sink and conservative design enable operating at full ratings to 60°C. No need to de-rate.
Ratings to 60A at 48VDC will handle solar arrays up to 4kW.
RS-232 2 connects to a personal computer for custom settings, data logging and remote monitoring and control.
DIP switch 3 provides the user with a choice of 7 different digitals 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 4 and conduit knockouts 5. Extra space for wire turns. Fits on power panels.
Better Battery Charging
Connecting battery sense wires 6 and the optional remote temperature sensor 7 will improve control accuracy. Constant voltage series PWM algorithm increases battery capacity and life.
3 LED’s 8 to indicate status, faults, and alarms. Optional meter 9 displays extensive system and controller information, automatic self-test and reset capabilities. Meter connection via RJ-11 phone jack 10.
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.
