Hi,

 

If you open intl.fusionsolar.huawei com in a web browser on a computer (or phone, tablet) that is connected to the BE550, does the webpage open normally or not?

 

In the instructions for the SUN2000 inverters Huawei writes "The WPA, WPA2, or WPA/WPA2 encryption mode is recommended for routers". So, in case you have currently set the BE550 to use "WPA3-Personal+WPA2-PSK[AES]", then try a security mode without WPA3 instead, like "WPA2-PSK[AES]" for example.

Hi, Thank you for responding. The Web browser opens that address. As you suggested I changed my 2.4 GHz to WPA2-PSK[AES] also to WPA/WPA2-personal but didn't work. I have also switched off smart connect to have a separate 2.4 GHz. I was looking at the Solar Inverter dongle and found an ethernet slot, so temporary I connected with ethernet and it's communicating with the reporting platform. Hence, it's some setting in the wifi which is blocking it. I have turned off access control too and the SPI firewall. There is something called as WMM in WiFi additional settings not sure what it does.

Well, then just test whether WMM disabled makes any difference. If it doesn't, then set it back to enabled.

 

You can also try the 2.4 GHz settings "Channel Width: 20 MHz" and "Mode: 802.11b/g/n mixed". Again, if the problem remains, then set them back to what they were originally.

 

Also verify the Wi-Fi signal is not too weak at the location of the inverter.

Thanks for reporting back the solution.
