2. Налаштування та встановлення

Follow these steps to properly install your SDongleA-05 Smart Dongle with a compatible Huawei SUN2000 inverter.

1. Підготовка інвертора: Ensure your Huawei SUN2000 inverter is powered off before installation.
2. Вставте ключ: Locate the USB port on your inverter. Carefully insert the SDongleA-05 Smart Dongle into the USB port. Ensure it is fully seated.
3. Захистіть з’єднання: If applicable, tighten the securing nut or mechanism on the dongle to ensure a firm and waterproof connection. The recommended torque is 0.8-1.1 Nm.
4. Підключення Ethernet (необов'язково): If using a wired Fast Ethernet connection instead of Wi-Fi, connect an Ethernet cable to the dongle's Ethernet port.
5. Увімкнення: Once the dongle is securely installed, power on your inverter. The dongle's LED indicator will illuminate, showing its status.

3. Інструкція з експлуатації

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

3.1 Режими зв'язку

• Wi-Fi зв'язок: 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 Світлодіодний індикатор

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. Технічне обслуговування

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

• Захист IP65: 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.
• Прибирання: 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.
• Огляд: Occasionally inspect the physical connection to the inverter and any connected cables for signs of wear or damage.

5. Вирішення проблем

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

• Немає зв'язку:
  • 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.
  • Переконайтеся, що інвертор увімкнено.
  • 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.
• Переривчасте підключення:
  • Check for potential sources of interference if using Wi-Fi.
  • Ensure the dongle's firmware is up to date (check Huawei support resources).
  • Перевірте стабільність мережі.
• 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.
