Multi-Axis Tracking Controller

Suzhou Ruitai's Multi-Axis Tracking Controller is built on an industrial-grade architecture, featuring IP65/IP66 protection and a wide operating temperature range of -40°C to +85°C.

It is designed to withstand harsh conditions, including deserts, high-altitude regions, and coastal areas. Supporting both 4G/5G and fiber-optic communication, the system ensures stable and efficient connectivity, while its low-power, self-sustaining design delivers dependable long-term operation.

Operating Principle

The Multi-Axis Tracking Controller (TCU) adjusts the angle of the PV mounting structure in real-time by integrating solar position algorithms, sensor feedback, and motor control technology.

Its basic operational workflow is: Solar position calculation → TCU generates control commands → Drive motor adjusts structure angle → Sensors provide actual position feedback → TCU corrects operational status → Data upload to NCU/SCADA.

1. Solar Position Data Acquisition

The TCU calculates the sun's trajectory based on time, latitude and longitude, date, and astronomical algorithms.

2. Tracking Structure Motion Control

The TCU sends control signals to the drive system, activating the motor and reduction mechanism to adjust the PV module angle, ensuring the modules remain oriented toward the optimal direction for sunlight exposure.

3. Position Feedback and Intelligent Calibration

The system detects the current status of the mounting structure using angle sensors, limit switches, and position feedback devices, automatically correcting any deviations.

The TCU also executes protective strategies based on environmental conditions—such as high-wind protection (Storm Stow), anti-collision protection, emergency shutdown protection, and limit position protection—to ensure safe operation.

TCU Key Advantages
