My lan dongle is offline, how to solve this issue?

Please follow the troubleshooting steps below firstly:

Step1:

Re-insert the dongle and make sure it is securely plugged in and making good contact. Wake up the inverter's LCD display to check Register SN. If the Registration SN on the Dongle appears as "Register SN" on the inverter, the connection between dongle and inverter is normal. If “NA” is displayed, re-plug the Dongle.

Settings path:

About → Inverter → Resister SN                                                 

Step2:

Connect the router to the computer using LAN connection, and check whether the computer can open the web page. Ensure that the router is functioning properly under the LAN network.

Step3:

Then, in the search bar of the computer, type 'cmd' to open the Command Prompt window.

In the window, type `ping mqtt101 .solaxcloud.com ` and press Enter to view the results. Normally circled area should show ‘Lost=0’, indicating normal operation. Take a screenshot to save this image.

Step4:

Check whether Pocket LAN can be found in the router. If it cannot, confirm whether there is a blacklist or if the number of access connections exceeds the limit.

If you have completed the above Guidance, and the problem is still not solved, please collect the following troubleshooting information contact our support agent.
