High Adaptability Sun Tracker Controller Wind Protection
Working principle:
A solar tracking controller is a device that orients a payload toward the Sun. Payloads are usually solar panels. For PV systems, trackers are used to minimize the angle of incidence between the incoming sunlight and a photovoltaic panel, sometimes known as the cosine error. Reducing this angle increases the amount of energy produced from a fixed amount of installed power generating capacity. As the pricing, reliability and performance of single-axis trackers have improved, the systems have been installed in an increasing percentage of utility-scale projects. Global solar tracker shipments hit a record 14.5 gigawatts in 2017. This represents growth of 32 percent year-over-year, with similar or greater growth projected as large-scale solar deployment accelerates.

Product info:
1. All parts meet IP65 grade (waterproof & dustproof)
2. May improve your solar panel’s power conversion efficiency by up to 25%
3. Safety, robustness, and reliability: Reverse voltage polarity protection + Overheating protection + Over current protection + Sensor sensitivity may be adjusted by the user.
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: Less electric control and driving unit, lower failure rate;
2: Strong adaptability, simple installation, convenient operation and maintenance;
3: Tracker could adjusts solar panels into horizontal in strong wind condition.
4: More reasonable wind resistance design;
Through the wind tunnel test, a more reasonable wind resistance mechanism can be obtained, which can more effectively guarantee the 25-year life of the power station.
