Comments:
① Key operation data (such as working status, alarm status, angle of inclinometer, etc.) will be stored in seconds. Each controller can store at least 100 pieces of valid data in 20s, while the continuous offline cache time will be maintained for at least one year.
② Key operation data (such as wind speed, wind direction, irradiation value and alarm information) will be stored in seconds. At least 100 pieces of valid data are stored per minute, and the continuous offline cache time can be up to three years.
③ The optional configuration includes built-in inclinometer and external inclinometer, supporting up to four inclinometers; single-point drive without external inclinometer.
④ Solve the “hot spot effect” caused by the shadow shielding between the tracking brackets caused by the difference in terrain height of the photovoltaic field area, and avoid the damage of the photovoltaic module and the loss of power generation caused by the “hot spot effect”.
⑤ When the communication interruption time between the gateway and the controller exceeds a certain time limit, the tracking bracket will enter the disconnection protection state to prevent damage to the tracking bracket due to special circumstances during the communication interruption.
⑥ If the controller cannot maintain the normal working power due to special circumstances, the equipment will enter the low-power protection mode and adjust the bracket to a safe angle to protect the mechanical structure of the tracking bracket to the greatest extent.
⑦ As a key component in the controller, the battery must have a comprehensive protection function to ensure that the tracking bracket is in the best and safe working state.
⑧ The work log of the control system has an encryption function, and only the person holding the key can be authorized to access the log.
⑨ Trained operators can complete the parameter configuration of a controller on site within 15s, greatly reducing debugging labor costs.
