The communication method is CAN or RS485, and it supports external EMS  (RS485), bidirectional electricity meter or CT (RS485).
• Debug the communication port COM-2 for professional technical maintenance personnel to use, supporting CAN or RS485 (inverter data can be accessed through this interface).
• The communication port COM-3 for the dry and wet contact signals reserved for the product.
• The specific information is shown in the table below.

DIP switch
The dial switch has a total of 6 digits. The following are the instructions and usage of the dial switch.

1. 6-digit dial switch, 1-5 is the reserved switch, and 6 is the communication internal resistance 120 Ω access switch.
2. When there are multiple F2400 connected to the grid, it is necessary to select one F2400 as the main device. Set the main device dial 1 to ON and 2-5 to OFF; The remaining F2400 dials 1-5 to OFF. After starting F2400, the main device will be automatically selected based on the dialing status.
3. When the product is locked due to a malfunction (fault code 68), dial 1-5 to ON and then all to OFF to clear the fault.

Grid connection function

EMS Energy Management
It is mainly divided into spontaneous self use mode, timed mode, and disaster recovery mode.
When the SOC is less than 10% (configurable through the APP) and there is no charging protection, the battery will no longer discharge and can only be charged.

Spontaneous self use mode (default mode)
This mode is suitable for grid areas with low-priced power generation and high electricity consumption, prioritizing the use of photovoltaic and battery energy, and minimizing the use of grid energy as much as possible. Specific working methods:

1. When the power grid is connected and the PV is sufficient, the PV prioritizes supplying power to the AC load and general load, then charges the battery, and any remaining energy can be connected to the grid.
2. When the power grid is connected and the PV is insufficient, the battery prioritizes supplying power to the load, and the insufficient power is then supplied to the load by the power grid.

Timer mode

Set the charging and discharging time period through the manual APP, such as during the low electricity price period at night, which can be set as the charging time period. The system charges the energy storage at maximum charging power during this period, and during the high electricity price period, it is set as the discharging time period. The battery can only be discharged during the discharging time period, saving household electricity costs.

Disaster recovery mode

• When the power grid is normal and the battery SOC is not 90% (SOC can be set), start charging (photovoltaic priority), and discharge when the power grid is abnormal.

F2400 communicates with smart sockets
To complete normal communication between F2400 and the smart socket, the following steps are required:

1. Bluetooth network configuration;
2. LAN device discovery;
3. LAN TCP communication.

Attention: Wired RS485 communication is required with bidirectional meters or CT modules.

Bluetooth network configuration
The APP sends WIFI information to F2400 and smart sockets through Bluetooth, completing the Bluetooth network configuration of F2400 and smart sockets respectively. The distribution network process uses the BluFi provided by ESP32, which is a WIFI network configuration function based on Bluetooth channel. The process diagram and the specific distribution network process of F2400 are as follows:

1. ESP32 enables GATT Server mode to send broadcasts with specific advertising data.
   This broadcast does not belong to the BluFi Profile and can be customized as needed. (The device name is configured as “RHG”, the broadcast content is 21 bytes, the first byte represents the device type, and the remaining 20 bytes represent the device SN number).

2. After searching for the broadcast using a mobile application, the phone will connect to ESP32 as a GATT client. There are no specific requirements for which mobile application to use in this step.

3. After successfully establishing a GATT connection, the phone will send data frames to ESP32 for key negotiation.

4. After receiving the data frame for key negotiation, ESP32 will parse it according to a custom negotiation method.

5. Key negotiation between mobile phone and ESP32. The negotiation process can use encryption algorithms such as DH/RSA/ECC.

6. After the negotiation is completed, the mobile end sends a control frame to ESP32 to set the security mode.

7. After receiving the control frame, ESP32 encrypts and decrypts communication data using a shared key and security configuration.

8. The mobile phone sends data frames defined in the BluFi frame format to ESP32, including Wi Fi configuration information such as SSID and password.

9. The control frame for the mobile phone to send a Wi Fi connection request to ESP32. After receiving the control frame, ESP32 assumes that the phone has completed the necessary information transmission and is ready to connect to WiFi.

10. After connecting to WiFi, ESP32 sends the control frame of the Wi Fi connection status report to the phone. At this point, the distribution network is over.

Attention: The intelligent socket distribution network process refers to the F2400 distribution network process and will not be explained in detail.

LAN device discovery

Using UDP multicast, the smart socket (abbreviated as WiFi device) sends an address to the multicast address after powering on. F2400 can receive messages as long as it listens to the address and replies to the message in UDP unicast mode. WiFi devices can also obtain the IP address of F2400 devices upon receiving the message. The UDP multicast address and port number are 232.10.11.12:3339. The process diagram is shown in the following figure.

The process of WiFi device discovery in local area network is as follows:

1. Triggered by power on, if no correct response is received, continue to send with a 1-second interval between sending;
2. After confirming disconnection from TCP Server, continue to send multicast messages;
3. After receiving the correct reply and obtaining the TCP Server IP address, end multicast message sending.

After receiving a multicast message from a WiFi device, F2400 will reply to the message in UDP unicast mode.

Within the local area network, WiFi devices act as TCP clients and F2400 acts as TCP servers for data transmission; WiFi devices report data every 1 second, and the server responds with the corresponding message after receiving the data; The fixed port number is 3333.
During TCP communication, there is a live function, as follows:

1. The server enables the liveliness function to determine whether the client is disconnected, and after the client is disconnected, relevant tasks are deleted;
2. If the client does not receive a reply message from the server within 5 seconds, it is considered that the server is offline and enters UDP multicast mode.
