Device Not Found

If you encounter issues with device enrollment during the process, and the "Device could not be found" information message appears, follow these steps:

Step 1: Double-check Inverter's Network Settings​

  • Ensure the inverter's network settings are correctly configured as per the provided instructions.

Step 2: Log in to RCT Power Portal​

  • Log in to the RCT Power Portal and check if the device is visible.
  • Allow at least 5 minutes after making any adjustments to the network settings.

Step 3: Check Internet Connection​

  • If the inverter connects to the Internet via Wi-Fi:

    • Verify the Wi-Fi connection with another device, preferably a laptop or smartphone.

  • If the inverter connects to the Internet via LAN:

    • Disconnect the plug from the inverter and connect it to another device, ideally a laptop, to test the LAN connection.

Step 4: DNS Check​

  • Open a web browser and visit https://dnschecker.org.
  • Enter the domain name in the DNS CHECK input field: rctgw.buildsys.cz.
  • Confirm with the Search button.

Check Results​

  • Positive results (green check mark) indicate a correct internet connection. If the issue persists, refer to other potential problems mentioned in this manual or the FAQs, or contact RCT support.
  • Negative results (red cross icon) suggest an incorrect internet connection. Resolve this issue with your network administrator and recheck the connection to the RCT Power Portal.
