Under the consensus of global carbon neutrality, the PV inverter industry, as one of the first new energy industries to be promoted in China, is bound to usher in a new round of rapid growth.

In the process of using a traditional PV inverter, in order to ensure safe operation, it is necessary to use the LCD to display the operating parameters and operating status of the inverter, and at the same time to use the button input to make some necessary settings for it. In the actual operation process, workers need to perform one-to-one monitoring settings on the inverter, which is cumbersome and unintuitive, and also brings some safety hazards. Here are the described methods of replacing the traditional display and operation with Bluetooth communication, which can solve the problems above.

Using Bluetooth modules to replace the traditional display and operation can easily connect directly with mobile phones or tablet computers for Bluetooth wireless control. There is no need to design a hand-held platform. The solution is more simple and feasible.

In order to facilitate access to the original system, RF-BM-BG22A1 module can be used to connect with the original system through the UART interface, so that the hardware and software design will be more simplified.

Features of RF-BM-BG22A1 module:

1. Support master-slave mode and master-slave simultaneous mode.
2. Support one master and multiple slaves (at most 7 slaves at the same time) connection under one module.
3. Support the high-speed transparent transmission under UART serial port, the highest rate is 50 kB/s, and the baud rate is up to 921600 bps.
4. Support AT commands to modify the device name, MAC address, connection interval, transmission power, and broadcast interval.
5. Support the self-defined modification of UUID.
6. Support the settings of self-defined broadcast data and extended broadcast packets.
7. Ultra-low power consumption, the measured average power consumption broadcast can reach 11 μA with the broadcast cycle of 1 second, and the sleep power consumption is 1.02 μA.
8. The RF-BM-BG22A1 module has FCC, CE, SRRC certifications.
9. The longest communication distance can reach 100 meters.

Through the Bluetooth PV inverter APP, you can view the real-time dynamics, set device parameters and obtain data conveniently and quickly, and eliminate potential safety hazards in time! One-click wireless transmission of parameter settings can greatly reduce the time for debugging! Spot check the terminal signal and ensure that the protection value of the AC relay is equal to the preset protection value. The log list is provided for users to choose and download, which is flexible, simple and convenient for users to analyze problems; the easy-to-operate alarm browsing function and flexible alarm query mechanism can quickly obtain fault location information, take timely countermeasures, and improve the operation and maintenance efficiency of user fault management.
