Intelligent and Sub-Controller Multi-Row Solar Tracker

Ruitai has its own factory to manufacture high quality Intelligent and Sub-Controller Multi-Row Solar Tracker. This TCU system serves as the intelligent core of the solar power plant.

It precisely controls the motor to adjust the angle of the PV panels in real time, allowing the system to dynamically follow the sun's movement throughout the day and capture more solar energy.

The system is further enhanced by its built-in neural network algorithm, which enables cloud-based remote learning and continuous optimization.

As sunlight conditions and site environments change, the TCU can adjust and improve its tracking strategy over time, helping the PV plant generate energy more efficiently.

Características técnicas do produto

1. Integração de Hardware e Software

The intelligent and sub-controller multi-row solar tracker supports both AC and DC power supply and is equipped with a high-capacity backup lithium battery, ensuring stable core control even at night or under harsh weather conditions.

With advanced intelligent tracking algorithms and high-precision 3D modeling technology, the system can effectively reduce shadow losses caused by complex terrain and improve overall energy generation.

Together with Ruitai's supporting mobile app and SCADA platform, the system enables full-process digital management, from fast installation to remote operation and maintenance.

2. Mecanismo de Proteção de Segurança

Under harsh wind conditions, the system uses our TCU and NCU can automatically adjust the PV panels to a safe parallel position, reducing wind load and protecting the tracker structure.

In specific situations, it can also identify independent tracker rows that are not affected by wind, allowing them to continue generating power safely.

Each NCU can also function as a micro weather station, enabling graded protection and fault-tolerance responses during extreme weather such as strong winds, heavy snow, and flooding.

The system is designed with high- and low-voltage separation, built-in electrical protection, and dual-layer software and hardware encryption, helping ensure the safety of personnel, equipment, and data.

4. Configuração de parâmetros e comissionamento

● Defina parâmetros básicos: Project latitude/longitude, time settings, tracking mode, and limit angles.

● Teste de funcionamento do motor: Test forward and reverse operation and maximum/minimum angles; verify correct direction of tracker movement.

● Calibração de ângulo: Align the actual angle with the system-reported angle using position feedback and tilt sensor data.

● Teste de comunicação: Verify communication between the TCU and NCU, including data upload, status feedback, and alarm notifications.

Wired vs. Wireless: Comparison of TCU Communication Methods

Ruitai’s intelligent multi-row solar tracker with sub-controllers supports various communication methods. We recommend the following:

For solar plants on flat terrain, prioritize the RS485 wired solution; for challenging deployment environments—such as mountainous or floating sites—wireless solutions may be considered, provided that signal coverage testing is thoroughly conducted.

Tipo de produto

To meet different project requirements, Ruitai provides a flexible product matrix for various tracker system configurations.

For single-row, single-drive applications, we offer two models: the DC-powered RT-TK-SP-V1 and the AC-powered RT-TK-EP-V1.

Both are designed to work with 300W motors and provide stable control for standard tracker rows.

For large-scale arrays with multiple rows and multiple drives, we provide a combined solution using a main controller and sub-controllers. This configuration supports motors of up to 150W and is suitable for more complex project layouts.

Whether the system uses string DC input or AC grid connection, Ruitai's control solution can be flexibly adapted to different site conditions and project needs.

Certificações e Garantia de Qualidade

Our intelligent and sub-controller multi-row solar trackers strictly comply with leading international and domestic standards. They have obtained ISO 9001 quality management system certification, CE safety certification, and safety standard inspection from HTW, an international testing and inspection organization.

In addition, the system software has also received a Computer Software Copyright Registration Certificate by the National Copyright Administration of the People's Republic of China.

Choosing Ruitai TCU products means choosing a compliant, reliable, and efficient control solution for the future of solar power generation.
