With the continuous advancement of technology, solar energy, as a clean and renewable energy source, has attracted increasing attention 

and favor. The solar MPPT controller is a key device in solar power generation systems, capable of real-time tracking of the maximum 

power point of solar panels. The application of Bluetooth technology brings more convenient and intelligent control methods to solar

MPPT controllers.

Roles of Bluetooth in Solar Controllers

1. Monitoring

Users can view the controller's working status through mobile phones, tablets, etc., including the output voltage, current, and power 

of solar panels, as well as the power level and charging status of batteries. This allows users to stay updated on the operation of the 

power generation system at any time.

2. Parameter Setting

Parameters of the MPPT controller can be configured via Bluetooth, such as charging voltage, current limits, maximum power, and 

tracking algorithms. Users can personalize the controller settings according to different types of panels and batteries, as well as varying

usage environments and requirements, to achieve optimal power generation efficiency.

3. Fault Diagnosis

When a fault occurs in the solar controller, it sends fault information to users via Bluetooth connection, such as overvoltage, undervoltage, 

overcurrent, overheating, etc. Users can promptly diagnose and resolve faults based on the information, enhancing the reliability and 

stability of the solar power generation system.
