Photovoltaic technology is becoming more and more important for us as society's demand for renewable energy continues to increase. 

It is not only an important means for us to achieve green, low-carbon and sustainable development, but also a key way for us to pursue

a better living environment and protect the blue sky and white clouds.

The composition of photovoltaic system: photovoltaic panel, photovoltaic controller, inverter, battery energy storage system

Photovoltaic controller is a kind of automatic control equipment used in solar power generation system, the main function is to control 

the solar panel to charge the battery and the battery to the solar inverter load power supply. The photovoltaic controller can monitor 

the working state of the photovoltaic system in real time to ensure the stable operation of the system, and send the data to the remote

monitoring center for centralized management and control through the communication interface.

In iot applications, Wi-Fi+ Bluetooth two-in-one module and PV controller can be used in combination to achieve remote monitoring 

and control of solar power generation systems.

Real-time monitoring: The PV controller sends real-time data of the system (such as power generation, battery level, system status, etc.) 

to the user's smartphone or tablet through the Wi-Fi+ Bluetooth two-in-one module. The user can check this information at any time 

to know the operating status of the system.

Remote control: Users can remotely control the PV system through smart devices. For example, they can set the operating parameters 

of the system, start or stop the system, adjust the maximum power Point tracking (MPPT) setting, etc.

Failure alarm: If the system fails, the PV controller will immediately send an alarm message to the user through the Wi-Fi module. This 

can help users detect and solve the problem in time and avoid the system downtime for too long.

Data analysis: By collecting and analyzing the operating data of the system, users can understand the performance of the system and 

optimize accordingly. For example, they can predict future power generation trends based on historical power generation data, so as 

to better plan electricity demand.

Remote upgrade: The program to upgrade the equipment through the module

Case effect:

Remote monitoring and management of the PV system is realized by integrating a PV controller with a Wi-Fi+ Bluetooth two-in-one module. 

The operating status of the system can be understood at any time, and problems can be found and solved in time. This not only improves 

the reliability and stability of the system, but also reduces the operation and maintenance costs. At the same time, renewable energy can 

be better utilized through the remote control function
