1. Product Overview
The Morningstar TriStar 60A Pulse Width Modulation (PWM) Solar Charge Controller (TS-60) is designed for reliable charging in larger off-grid solar systems. It regulates power from the solar array to the battery bank, ensuring consistent energy harvesting and optimal battery health. This controller is suitable for 12V, 24V, 36V, and 48V lead-acid (LA) and lithium (Li) battery systems.
Key features include:
- 60A PWM Control: Provides efficient and reliable charging for various battery types.
- Networking & Communications: Supports monitoring, data logging, and adjustability via open standard MODBUS protocol, PC connection, bus device communication, and Ethernet for web-enabled local network interface. Includes IP-based network and internet connectivity, with Simple Network Management Protocols (SNMP) support.
- Solid-State Design: Features a fanless thermal heat sink and no moving parts, contributing to enhanced durability and quiet operation.
- Electronic Protections: Built-in safeguards against surges, short-circuits, overloads, reverse polarity, high voltage, and high temperature disconnects. Advanced self-diagnostics and automatic recovery ensure continuous system protection.

2. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your TriStar controller. Always consult the full product manual for detailed wiring diagrams and safety precautions. Ensure all connections are secure and correctly polarized.
2.1 Wiring Connections
The TriStar controller connects to the solar array, battery bank, and optionally to a load or diversion system. Follow the recommended wiring sequence: first connect the battery, then the solar array, and finally any loads or diversion equipment. Ensure appropriate wire gauges are used for all connections to prevent overheating and voltage drops.

2.2 Communication Setup
For advanced monitoring and configuration, the TriStar controller can be connected to a computer. This typically requires a serial-to-USB adapter and the installation of appropriate drivers for your operating system. The Morningstar MSView software allows for detailed diagnostics, data logging, and adjustment of settings. Ensure the serial cable connection is secure and fits properly, potentially requiring a specialized jumper cable for permanent connection within the enclosure.
2.3 Firmware Updates
To ensure optimal performance and access to the latest features, it is recommended to periodically check for and install firmware updates for your controller. These updates are typically available through the Morningstar website and require a computer connection.
3. Operating Instructions
Once installed and configured, the TriStar controller operates automatically to manage your solar power system. It continuously monitors the battery state of charge and adjusts the PWM charging algorithm to optimize battery life and performance.
3.1 Charging Process
The controller utilizes a constant voltage series PWM algorithm. This method ensures that batteries are charged efficiently and maintained at optimal levels. For lead-acid batteries, the controller performs automatic cell balancing every 28 days to enhance battery health and longevity.
3.2 System Monitoring
The TriStar controller provides various options for system monitoring:
- LED Indicators: The controller features LED indicators for basic status updates.
- Remote Meter (Optional): An optional remote meter (TS-RM-2) can provide real-time data and system parameters.
- Software Interface: Connecting to a PC with Morningstar's MSView software allows for comprehensive data logging, detailed diagnostics, and remote configuration.
- Network Connectivity: Through Ethernet and SNMP, the controller can integrate into local networks for web-enabled monitoring, including email and text alerts.

4. Maintenance
The Morningstar TriStar TS-60 is designed for minimal maintenance due to its robust, solid-state construction. There are no moving parts or fans that require regular cleaning or replacement.
- Periodic Inspection: Regularly inspect all wiring connections for tightness and signs of corrosion.
- Environmental Conditions: Ensure the controller is installed in a location that meets the specified operating temperature range and is protected from excessive dust or moisture.
- Software Updates: Keep the controller's firmware updated to benefit from performance enhancements and bug fixes.
5. Troubleshooting
The TriStar controller includes advanced self-diagnostics to alert users to potential issues. If a problem occurs, the LED indicators will provide a preliminary status. For detailed diagnostics, connect the controller to a computer using the MSView software.
Common Issues and Solutions:
- No Power/No Indication:
- Verify battery connections are secure and correctly polarized.
- Check battery voltage; ensure it is within the controller's operating range.
- Controller Not Charging:
- Inspect solar panel connections and ensure they are receiving adequate sunlight.
- Check for open circuits or short circuits in the solar array wiring.
- Confirm battery voltage is below the charge setpoint.
- Communication Problems with PC:
- Ensure the serial-to-USB adapter drivers are correctly installed on your computer.
- Verify the serial cable is securely connected to both the controller and the adapter.
- Check the COM port settings in the MSView software.
- Error Codes/Blinking LEDs:
- Refer to the detailed error code section in the comprehensive product manual for specific interpretations and corrective actions.
- The controller's automatic recovery feature will attempt to resolve temporary faults.
