The TriStar is a 3-function controller that provides reliable solar battery charging, load control or diversion regulation. It operates in one of these modes at a time and two or more controllers may be used to provide multiple functions. It also supports parallel operation for larger solar arrays of up to 300 Amps or more as well as 4-stage charging to increase battery capacity.

Key Features and Benefits
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.
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.
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.
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
Push-button 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.
