EPEVER RTU 4G A is suitable for EPEVER solar controller, inverter, and inverter/charger.
Features:

• Extensive network coverage and flexible networking
• Low operating costs (charged by network flow)
• Adopt a non-standard DB9 male terminal
• Embedded in Modbus RTU protocol
• Automatic restore after disconnection
• Support RS485 communication

Parameter Configuration

1. Step1: Connect the DB9 male connector ❸ to the PC through a DB9 to USB adap t er .
   Note: Connect an external power adapter to the DB9 female terminal to supply the EPEVER RTU 4G A.

2. Step2: Insert the SIM card and power on the EPEVER RTU 4G A. For detailed SIM card installation, refer to chapter 6, Installation.

3. Step3: Open the configuration tool on the PC and click the “connect” button to connect the EPEVER RTU 4G A successfully.

4. Step4: Click the “Read” and “Write” buttons to configure the parameter. Step5: After configuring, power on the product again to make the modified parameters take effect.

Common configuration parameters:

APN

| Different countries have different APNs, and please make sure APN first. Products will not be connected to the Internet with fault APN.

China APN: CMNET

APN User| Enter it according to the actual
APN Key| Enter it according to the actual
Baud| Set it according to the connected controller or inverter

Note: The “APN” will be identified automatically. If it cannot be identified, the end-user can configure it by the above procedures.

Installation

Step1: Install the SIM Card

1. Purchase a SIM card and activate the GPRS service.
2. Undo the three screws from the EPEVER RTU 4G A.
3. Push the shell upward and take out the circuit board.
4. Take out the small SIM card and insert it into the card slot correctly.
5. After installing successfully, reinstall the product shell.

Step2: Install the silicone pad

Tear off the silicone pad’s adhesive and stick the silicone pad to the DB9 terminal of the EPEVER RTU 4G A.
Step3: Install the antenna
Connect the 4G antenna to the antenna port of the EPEVER RTU 4G A.
Caution: As a wireless terminal, keep the antenna away from the human body as far as possible during the operation process. Step4: Connect the device
Take the connection with the solar controller as an example.
Connect the DB9 connector of the RS485 communication cable to the EPEVER RTU 4G A, then connect the ends of the RS485 communication cable to the master LORA module and the battery separately.
Note: The EPEVER RTU 4G A supports 9~48V DC power. While a larger transient current is needed when the wireless network sends the data, it is suggested to adopt a DC power of 12V/500mA or above.
Note: If the EPEVER RTU 4G A is connected with the inverter or inverter/charger. Connect the DB9 connector of the RS485 communication cable to the EPEVER
RTU 4G A. Then connect the ends of the RS485 communication cable to the battery and the device COM port. The master LORA module is no longer needed.

6. Step 6: Select the connected module (the EPEVER RTU 4G A).
7. Step 7: Input the ID (or scan the QR code) on the module label, and click “Confirm” to enter the Plant or Light project page directly.

Troubleshooting

LED indicators are OFF

| 1.   Check whether to supply power to the EPEVER RTU 4G A.

2.   Check whether the power supply’s poles are connected inversely. The EPEVER RTU 4G A is equipped with anti-reverse protection. The reverse connection does not cause fatal damage. However, it affects the normal use before the correct connection is restored.

The network indicator is ON solid

| After power is on, the network indicator is on solid for 60 seconds. If it still cannot flash after 60 seconds, please check:

1. Check whether the SIM card is inserted correctly. 2. Check whether the GPRS service is activated. The Network indicator is on solid again after running for a while:

1. Check whether the server status is normal. 2. Check whether the SIM card is loose or arrear.

Smoke emits along with a pungent smell| The connected battery voltage exceeds the rated voltage, causing the internal components to burn out. Don’t hesitate to contact the supplier in time and send it to the manufacturer.

Unregister on the network

| 1. Check whether the SIM card is inserted correctly. 2. Check whether the SIM card has activated the GPRS service.

3. Check whether the input power is sufficient. Input power should be 12VDC/500mA.

Parameters can’t be configured| 1. Check whether the connection to the PC is correct. 2. Check whether the serial port selection is correct.
