Troubleshooting

No.

Fault

Cause

Suggestions

1

The SmartLogger cannot be powered on.

  1. The DC output power cable for the power adapter is not connected the 12V IN port of the SmartLogger.
  2. The power cable is not connected to the AC power input port of the power adapter.
  3. The AC input power cable is not connected to the AC socket.
  4. The power adapter is faulty.
  5. The SmartLogger is faulty.
  1. Connect the DC output power cable for the power adapter to the 12V IN port of the SmartLogger.
  2. Check that the power cable is connected to the AC power input port of the power adapter.
  3. Check that the power cable is connected to the AC socket.
  4. Replace the power adapter.
  5. Contact the dealer or Huawei technical support.

2

The SmartLogger cannot find any device.

  1. The COM ports are not connected to devices, or the cables are loose, disconnected, or reversely connected.
  2. The RS485 communications parameters are not correctly set, and the solar inverter address is beyond the search range preset on the SmartLogger.
  3. The devices that cannot be detected automatically, such as the EMI and power meter, are not manually added.
  1. Check the RS485 cable connection. If the cable is loose, disconnected, or reversely connected, reconnect it firmly.
  2. Check the RS485 communications parameter settings. Ensure that the baud rate and communication address are set correctly and that the solar inverter address is within the search range of the SmartLogger.
  3. Manually add the devices that cannot be detected automatically, such as the EMI and power meter.
  4. Contact the dealer or Huawei technical support.

3

The communication for MBUS networking failed.

  1. The solar inverter and SmartLogger do not support MBUS.
  2. The AC power cable is loose, disconnected, or reversely connected.
  3. The upstream circuit breaker for the AC power cable is turned off.
  4. In MBUS networking, Built-in MBUS or Networking is set to Disable.
  5. The SmartLogger is faulty.
  1. Check whether the solar inverter and SmartLogger support MBUS.
  2. Check the AC power cable. If it is loose, disconnected, or reversely connected, reconnect it firmly.
  3. Check that the upstream circuit breaker for the AC power cable is turned on.
  4. Set Built-in MBUS and Networking to Enable.
  5. Contact the dealer or Huawei technical support.

4

The device status is displayed as disconnected on the SmartLogger.

  1. The cable between the solar inverter and the SmartLogger is loose or disconnected.
  2. The solar inverter is powered off.
  3. The baud rate or RS485 address of the solar inverter is changed.
  4. The solar inverter is replaced.
  5. The solar inverter is removed and not reconnected.
  1. Check the cable between the solar inverter and the SmartLogger. If the cable is loose or disconnected, reconnect it firmly.
  2. Check the solar inverter connection and power on the solar inverter.
  3. Check that the baud rate and RS485 address of the solar inverter are set correctly.
  4. If any device is replaced, search for the device again or manually add the device.
  5. If the device has been removed, perform the Remove Devices operation on the Device Mgmt. page.

5

The EMI fails in communication.

  1. The RS485 communications cable between the EMI and the SmartLogger is connected incorrectly, loose, or disconnected.
  2. The EMI is not powered on.
  3. The EMI and SmartLogger use different RS485 communications parameter settings.
  4. The EMI parameters are incorrectly set.
  1. Check the cable connection. If the cable is loose or disconnected, reconnect it firmly.
  2. Power on the EMI.
  3. Check that the RS485 communications parameters of the EMI are correctly.
  4. Log in to the WebUI and ensure that the EMI parameters are set correctly.

6

The SmartLogger cannot communicate with the management system.

  1. The SmartLogger is not connected to the PC, or the cable is loose or disconnected.
  2. The parameters of the wired or wireless network are incorrectly set.
  3. The management system parameters are incorrectly set.
  1. Check that the Ethernet port of the SmartLogger is correctly connected to the PC or a router.
  2. Check that the parameters of the wired or wireless network are set correctly.
  3. Check that the management system parameters are correctly set.

7

The communication for RS485 networking failed.

  1. The RS485 communications cable is incorrectly connected, loose, or disconnected.
  2. The SmartLogger is not powered on.
