SurgeTrack TCU DC24 Solar Tracker Controller

Product Introduction

The SurgeTrack TCU DC24 is a row-level solar tracker control unit designed for photovoltaic (PV) plants that use an external 24V DC power supply. It supports real-time solar tracking, precise motor actuation, and flexible communication to help improve tracker responsiveness and simplify system integration.

Combining an astronomical algorithm with position sensor feedback, this controller supports tracking accuracy of less than ±1° and a tracking range of -60° to +60°. Its communication options include Sub-1GHz, LoRa Mesh, RS485, and Bluetooth, while the Modbus RTU protocol facilitates integration with compatible control systems.

Designed for demanding outdoor solar installations, the TCU features an IP67 protection rating and an operating temperature range of -35°C to +60°C. Plug-and-play wiring, self-forming mesh networking, and remote firmware updates help reduce configuration effort and simplify ongoing maintenance.

The SurgeTrack TCU DC24 is suitable for PV projects that require a DC-powered tracking architecture, adaptable operating modes, and reliable row-level control.

Key Product Features and Advantages

1. 24V DC Power Supply

Designed for solar tracking systems standardized on a 24V DC power architecture, the controller operates from an external 24V DC supply. This configuration supports integration into compatible tracker installations.

2. Precise Solar Tracking Control

The combination of an astronomical algorithm and position sensor feedback supports accurate solar positioning. With tracking accuracy of less than ±1° and an adjustable motor speed, the controller helps coordinate tracker movement according to operating requirements.

3. Flexible Communication Options

The controller supports Sub-1GHz, LoRa Mesh, RS485, and Bluetooth communication. Modbus RTU protocol support enables communication with compatible equipment, while multiple connection options offer flexibility for different project configurations.

4. Self-Forming Mesh Networking

The self-forming mesh network reduces the need for individual TCU configuration. This feature can simplify deployment across large solar installations and help streamline network setup.

5. Outdoor Protection and Wide Temperature Range

With an IP67 protection rating and an ambient operating temperature range of -35°C to +60°C, the controller is designed for outdoor PV environments exposed to challenging weather conditions. The specified altitude limit is below 4,000 m.

6. Multiple Operating Modes

The controller supports Auto, Fault, Night, Fixed Angle, Heavy Rain, Strong Wind, Heavy Snow, Maintenance, Stop, and Farm modes. These options allow the tracking system to respond to different operating, environmental, and maintenance requirements.

7. Integrated Protection Functions

Overcurrent protection, overvoltage and undervoltage protection, night return, and backtracking are supported. Wind, snow, and rain protection are available as optional functions and require the corresponding sensors, such as an anemometer, snow depth sensor, or rain gauge.

8. Low Daily Power Consumption

The specified daily consumption is 0.05 kWh/day. Low power consumption helps limit the controller's contribution to the overall auxiliary energy demand of a solar tracking system.

9. Convenient Debugging and Maintenance

Debugging is supported through PC, mobile, or NCU interfaces. Plug-and-play wiring and remote firmware updates help simplify commissioning and maintenance, subject to the compatible system configuration.
