3. 사용 설명서

The SDongleA-05 facilitates communication between your Huawei SUN2000 inverter and the management system, typically a monitoring platform or app.

3.1 통신 모드

• 와이파이 통신: The dongle connects to your local Wi-Fi network, allowing the inverter to transmit data wirelessly to the management system.
• Fast Ethernet (FE) Communication: For a wired connection, the dongle uses an Ethernet cable to connect to your network, providing a stable data link.

3.2 Device Cascading

One dongle can be used to cascade multiple inverters via RS485 communication. This allows a single dongle to manage data from several inverters, simplifying system setup.

• A maximum of 10 devices can be cascaded.
• If the cascaded inverters include a single-phase inverter or are connected to batteries, a maximum of three inverters can be cascaded.

3.3 LED 표시등

The dongle features an LED indicator that provides status information. Refer to the inverter's or dongle's specific manual for detailed LED status interpretations (e.g., solid green for normal operation, blinking for connection attempts).

4. 유지관리

The Huawei SDongleA-05 Smart Dongle is designed for minimal maintenance due to its robust construction and intelligent features.

• IP65 보호 : The device has an IP65 protection class, meaning it is dust-tight and protected against low-pressure water jets from any direction. This makes it suitable for outdoor installation.
• Automatic Connection Restoration: In the event of a connection failure, the dongle attempts to automatically restore the connection, minimizing downtime and ensuring continuous data transmission.
• 청소: Periodically, you may gently wipe the exterior of the dongle with a soft, dry cloth to remove any dust or debris. Do not use harsh chemicals or abrasive materials.
• 점검: Occasionally inspect the physical connection to the inverter and any connected cables for signs of wear or damage.

5. 문제 해결

If you encounter issues with your SDongleA-05 Smart Dongle, consider the following common troubleshooting steps:

• 통신 없음:
  • Check the dongle's LED indicator. Refer to the inverter or dongle manual for LED status meanings.
  • Ensure the dongle is securely inserted into the inverter's USB port.
  • Verify that the inverter is powered on.
  • If using Wi-Fi, check your Wi-Fi network's status and ensure the dongle is within range and correctly configured (refer to the inverter's network setup guide).
  • If using Ethernet, ensure the Ethernet cable is properly connected to both the dongle and your network router/switch.
• 간헐적인 연결:
  • Check for potential sources of interference if using Wi-Fi.
  • Ensure the dongle's firmware is up to date (check Huawei support resources).
  • 네트워크 안정성을 확인하세요.
• Cascading Issues:
  • Ensure the RS485 communication cables between inverters are correctly connected.
  • Verify that the number of cascaded devices does not exceed the maximum limits (10 devices in general, 3 if single-phase or battery-connected inverters are present).

For persistent issues, consult the detailed troubleshooting section of your Huawei inverter manual or contact Huawei/Avoltik technical support.
