Product Description

      T220 is a two-axis tracking controller developed by SMARTracker. Based on the local longitude, latitude and time, the program automatically calculates the sun's motion trajectory and azimuth and altitude Angle of the location at any time. In the tracking stage, the system automatically issues commands according to the tracking range to control the operation of the electric actuator, and automatically adjusts the tracking Angle every period of time, so as to control the all-weather, all-temperature and high-precision tracking, so that the photovoltaic module is always aligned with the current position of the sun. Under bad weather conditions, the upper computer communication system tells the control system that there is a strong wind weather, issues instructions and tells the control system. The control system drives the motor, and the support makes corresponding actions to avoid bad weather. When the solar altitude Angle is low, the system enters the phase of anti-shadow tracking to avoid the shadow blocking of the bracket. The whole control process is fully automatic without manual intervention (the system runs in "AUTO" mode)..

 Schematic diagram
The dual-axis tracking controller is composed of a tracking control box and a sensor. The sensor + time + astronomical algorithm is adopted to realize automatic closed-loop control, with intelligent functions such as overload, short circuit, wind protection, rain and snow protection, night mode, manual tracking, remote control and so on.


Electrical schematic diagram
The tracker system is divided into three parts: the sensor part, the control box part and the asynchronous motor part. The control box receives and judges the signals of each sensor (tilt sensor) and controls the rotation of the motor through program calculation. To track the sun. The internal composition of the tracker control box is as follows:
