Working principle:
Ground mounting single axis solar tracking system components slew drive solar panel mounting brackets is controlled by the tracking controller, with simple structure, easy installation, flexible response, good reliability and strong fault identification ability. Compared with traditional fixed inclination installation, the generating capacity can be increased by 15%-20% (depending on local conditions).
Functions:
1. Single row independent drive unit, no connection between row and row, to ensure convenient traffic between square array;
2. Slew drive design, with high transfer efficiency and good environmental adaptability, the drive unit can be maintained free for 25 years;
3. Adopt the form of self-power supply, without external power supply;
4. Independently developed MCU microcomputer control system;
5. Intelligent battery management system (BMS) and automatic alarm functions can ensure the system's long-term reliable operation.
