Morningstar Tristar45 Three Function Solar 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.

• 5 year warranty period

Key Features and Benefits

Highest Reliability
Large heat sink and conservative design enables operating at full ratings to 45°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.

Full 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 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.

Three Function Solar Controller

Charge Control

• Constant voltage series PWM design to provide highly efficient battery charging
• 4-stage charging to increase battery capacity and life: bulk charge, PWM regulation, float and equalize
• Parallel for larger solar arrays up to 300 amps or more

Load Control

• Starts large loads including motors and pumps with no damage to controller
• Allows inrush current to 300 amps
• Electronic short-circuit and overload protection with automatic reconnect
• LVD is current compensated and has a delay to avoid false disconnects

Diversion Control

• May be used for solar, wind or hydroelectric
• To protect against battery overcharge, excess energy is diverted from primary battery to a secondary battery or alternate DC resistive load
• PWM reduces power into diversion load during overcurrent conditions
