1. How does the solar tracker controller TCU improve the efficiency of the solar tracker?

The Solar Tracker Control Unit (TCU) is the motor controller for the PV tracking mount. TCU automatically calculates the sun's trajectory according to the longitude, latitude and time, and automatically calculates the azimuth and altitude of the location at any time. The system is still in the automatic tracking mode, according to the current position of the sun. The tracking command is issued to control the rotation of the motor to make the photovoltaic The modules are always aligned with the sun at the optimum inclination, which increases power generation.

There are three default modes in the TCU: automatic mode, manual mode and stop mode. The most commonly used mode is the automatic mode, where the TCU automatically commands the solar mount to align with the sun. In manual mode, rotation requires manual instructions, usually during the adjustment and testing phases. The last mode only allows to avoid misoperation in special cases, and does not accept any manual and automatic instructions.

The solar tracker control unit has intelligent one-key upgrade, wireless AD-Hoc networking, anti-shadow tracking, strong wind, snowstorm protection, overcurrent and overtemperature protection. TCU can be matched with NCU and SCADA without complicated process and long time.

There are two types of power supply for the solar tracker control box. One is AC power supply, connected to AC200V, and the other is self-powered by PV strings, with an input voltage range of DC250V-1500V. The second type of TCU is equipped with a lithium battery and a self-developed BMS. BMS takes the lead in adopting the constant current and constant voltage charging method at different temperatures to prevent overcharging of the battery, protect the battery from damage, and enhance the stability of the control system.

Ⅱ. The advantages of solar tracker controller TCU

1. Large watertight structure

The controller is installed with the navigation plug facing down. On the one hand, it is waterproof through its own weight, and on the other hand, the extreme structural design can also ensure normal operation under storm conditions.

2. Convenient human-computer interaction

There are simple and intelligent buttons on the controller, which can be adjusted after installation. Equipped with special debugging tools, it is easy to operate and reduces deployment cycle and manpower.

3. Powerful IoT cloud platform

Simple operation can connect to the cloud platform, realize remote operation and maintenance monitoring, and monitor the system running status in real time.

4. Support intelligent AI

It is a new generation of big data-driven closed-loop self-learning tracking system solutions, relying on neural network-based topology algorithms to increase power generation.
