Low Maintenance Solar Sun Tracker With Backtracking
Working principle:
Solar sun trackers are rising in popularity, solar panel tracking solutions are a more advanced technology for mounting photovoltaic panels. Stationary mounts, which hold panels in a fixed position, can have their productivity compromised when the sun passes to a less-than-optimal angle. Compensating for this, solar trackers automatically move to track the path of the sun across the sky, thereby maximizing output.
The structure is robust and reliable, the torsion resistance of the main torque tube is higher;
Intelligent control Automatic identification and protection of all kinds of natural conditions (rain, snow, wind, etc.)

Functions:
1. High reliability: It can handle freely in the area with serious electromagnetic interference. Its excellent electromagnetic compatibility design ensures high reliability operation of the system.
2. Intelligent wind resistance: It is automatically leveled to the initial position at night. At the same time, the system has a wind load protection interface and supports an external wind speed sensor, which can control the system to enter the maximum wind resistance state of the machine at any time.
3. Power-off memory: There is a backup battery inside the system, which can ensure that the system power-off data is not lost, and automatically enters the running state after power-on.
4. Strong weather resistance: The system uses industrial grade chips and aerospace-grade clock sources to ensure safe and stable operation of the equipment in the range of -40 to +70 degrees without cumulative error.
Advantages:
1. Minimum number of drives for every MWp installed.
2. Minimum energy consumption.
3. Compatible with different foundation solutions: ramming, micropiles, concrete pads, predrilling, screw pile.
4. Compatible with all PV modules (framed, glass-glass, thin-film, bifacial)
5. Preassembled joints and components.
6. 100% bolted connections. No drilling, cutting, or welding on-site.
7. High tracking accuracy, average tracking accuracy is ≤1°
8. The interval time of continuous tracking is adjustable;
9. Can move to scheduled position when there is wind ;
10. East-West orientation limiting ;
11. Wrong battery pole connection protection, with over-current protection fuse;
