String Powered Tracker Control System Motor Overload Protection
Working principle:
Tracker control system is mainly applied to large-scale solar power
plant at low latitude areas. One motor and control system make the
whole solar module array track automatically. The unique linkage
structure and slew bearing ensure the stability of the whole
system, low failure rate and maintenance cost. It is a good choice
for large-scale solar power plant with roughly 25% power
generation, comparing to fixed type.

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.
Advantage:
1. Automatic Tracking without Manual Debugging
With good environmental adaptability, no affection by extreme
weather; Wide Range of tracking angle improves the power output.
2. Equipped with GPS to Ensure the Accuracy of Time
High weather resistance contributes to safe and stable operation
between -40℃-70℃, excellent electromagnetic compatibility design
makes the system stable and reliable.
3. Remote Communication, Group Control for Multi-Equipment
Automatically identify the failure, with automatic self-protection
and alarm；Quadruple over-current protection ensures the safety of
the whole system.
4. Customized System Configuration Available
It can be designed according to customer’s specific requirement.
5. Less quantity of posts.
Cleaning equipment can easily enter to clean solar panels without
any obstacle and risk.
