The Good Future String-powered TCU(Tracking Control Unit) for PV tracker system offers a highly efficient and reliable tracking control solution for solar power plants through its advanced technology and innovative design. 

Multiple solar panel groups are connected in series, generating a voltage range between 300V and 1500V. These series-connected solar panels directly power the TCU, eliminating the need for external power sources. To ensure system stability and versatility, the TCU also supports a 48V power supply, adapting to different application scenarios and requirements. The built-in voltage regulation module ensures stable voltage and current under varying light conditions, guaranteeing the normal operation of the control unit and actuators.

Tracking Control:

Sensor Data Processing: The TCU receives and processes data from light sensors, angle sensors, and temperature sensors.
Intelligent Calculation: Based on sensor data, the TCU calculates the optimal tilt and azimuth angles for the solar panels to maximize sunlight capture.
Motor Adjustment: The TCU controls motors or hydraulic systems to adjust the solar panel angles precisely, achieving accurate solar tracking.

Data Transmission and Monitoring:

Real-time Monitoring: Equipped with a communication module, the TCU can transmit system status and performance data to a central control system. Good Future’s powerful cloud platform and the debugging system can monitor the status of the solar tracking system in real-time. Operators can monitor, modify, and maintain the entire PV power generation system or any individual solar tracker from their mobile phone, tablet, or computer, ensuring the stability of the whole power generation system.

Self-Inspection and Fault Diagnosis:

Self-Inspection: The TCU continuously monitors its own status and that of the solar tracking system to ensure everything runs smoothly.
Fault Diagnosis: If any faults or anomalies are detected, the TCU records the relevant information and alerts the operators for maintenance.

Advantages

Compared to traditional solar tracking control units, the Good Future String-powered TCU offers several significant advantages:

Comprehensive Battery Solution: In Good Future’s string-powered solution, batteries serve as a backup power source, primarily used for moving the trackers at night or when voltage drops necessitate tracker movement. Compared to self-powered solutions, this reduces wear and tear as the depth of discharge (DoD) is significantly lower. The batteries are recharged every morning, ensuring their availability and allowing for shallow charging cycles, thereby extending their lifespan.

Conveniently Removable Battery Compartment: Although Good Future has equipped the TCU with a reliable battery solution, we have also considered practical usage scenarios by providing the controller with a removable battery compartment. If the original battery is damaged, operators can easily replace the battery with a simple operation extending the TCU’s operational time.

Intelligent Current Control: The Good Future String-powered TCU is equipped with built-in devices and algorithms that can precisely sense current. Intelligent control maximizes the protection of the battery and the overall operation of the power generation project.

Multiple Power Supply Modes: Supports both string supply (300V-1500V) and 48V power supply, providing flexible power solutions for different scenarios and needs.

Self-Powered Design: Powered by series-connected solar panels, it eliminates dependence on external power sources, making the system more independent and reliable, especially in remote or off-grid areas.

Cost Savings:  Competitive prices can save costs for project owners and maximize profits.

Simplified Installation: The power system design and wiring are simplified, making the installation process quicker and easier, reducing construction time and complexity.

High Reliability: Minimizing the use of power cables, it reduces the risk of system downtime due to cable failures, enhancing overall system reliability.

Intelligent Control: Uses advanced sensors and algorithms to precisely adjust the solar panel angles, ensuring the panels are always in the optimal position, thus improving energy generation efficiency.

Real-time Monitoring and Remote Management: Offers real-time data monitoring and remote management capabilities, allowing operators to keep track of the system’s operation and make timely adjustments and maintenance to ensure efficient performance.

The Good Future String-powered TCU stands out with its innovative design and superior performance, providing a more efficient and reliable solution for solar power plants. By adopting this advanced tracking control unit, solar power plants can maximize their use of solar resources, achieve higher energy generation efficiency, and reduce operating costs.
