Solar Tracker Control System Self Checking Function
Working principle:
HWL tracker controller, using AC power supply, with super small
volume, cast aluminum chassis, 25 years no rust, installed on the
torque tube, easy installation. The core technology of our solar
tracker control system is based on the local longitude, latitude,
time, the program can automatically calculate the azimuth Angle and
altitude Angle of the sun's trajectory and its location at any
time.
During the tracking stage, the system will automatically issue
instructions according to the tracking range to control the
operation of the electric actuator, and adjust the tracking Angle
every once in a while (so as to make the photovoltaic modules
always align with the position of the current sun.Under bad weather
conditions, the upper computer communication system tells the
control system there is a strong wind weather, sends out
instructions, tells the control system, the control system pushes
the motor, and the bracket makes corresponding actions to avoid bad
weather.When the sun altitude Angle is low, in order to avoid the
shadow occlusion of the support, the system enters the anti-shadow
tracking stage.The whole control process is fully automatic without
manual intervention (the system runs in "AUTO" mode).
