6. メンテナンス

The TSUN MS300 Micro Inverter is designed for minimal maintenance due to its robust construction and IP65 rating. However, periodic checks are recommended to ensure optimal performance and longevity.

• 目視検査: Periodically inspect the inverter and its connections for any signs of physical damage, corrosion, or loose wiring.
• クリーニング： If necessary, gently clean the exterior of the inverter with a soft, damp cloth. Do not use abrasive cleaners, solvents, or high-pressure water jets, as this may damage the casing またはシール。
• 換気： Ensure that the area around the inverter remains clear of obstructions to allow for proper airflow and heat dissipation.
• ファームウェアの更新： Check the monitoring application or TSUN's official website for any available firmware updates for your inverter. Follow the instructions carefully for any update procedures.

7。 トラブルシューティング

If you encounter issues with your TSUN MS300 Micro Inverter, refer to the following troubleshooting steps:

• 電力出力なし:
  • Check DC connections from the solar panel to ensure they are secure and correctly polarized.
  • Verify AC connections to the grid are secure and that the circuit breaker is not tripped.
  • Ensure there is sufficient sunlight reaching the solar panel.
• Wi-Fi 接続の問題:
  • Wi-Fi ルーターの電源がオンになっていて、正しく機能していることを確認します。
  • Check the distance between the inverter and the Wi-Fi router. Signal strength may be an issue.
  • Restart the inverter and attempt to reconnect via the monitoring app.
• Error Messages in App:
  • Refer to the monitoring application's help section or TSUN's online resources for specific error code explanations and solutions.
• 出力低下:
