Hello all
Recently we've encountered a lot of troubles during the commissioning process of the residential inverters (SUN2000L / L1 models, M0/M1/M2 models).
As you already know, Huawei inverters relies only on 2.4GHz frequency which means that they can connect only on the 2.4GHz routers.
Nowadays, more and more routers supports both frequencies (2.4GHz / 5GHz) and also they have a function called "Smart Connect" (at least on my router) which if it's Enabled it will create a single, unified SSID (network name) that you can log into using a single password.
So instead of having 2 Wi-Fi networks (as an example: TPLink2.4 & TPLink5, you'll have only one SSID called: TPLink). Basically, this function means automatically giving each device access to every band and assigning it to the best one (when you connect a device to your router, Smart Connect will automatically identify the best available channel and assign the device to it).
As far as I know, this function is not enabled by default and you have to login locally on the router page and to set it up. On my router, I had to enable it and disable it manually but maybe in other types of routers, it's enabled by default since the installation time.

If this function is enabled, the inverter will not be able to identify the network so as a conclusion, it will not be able to connect to it.
If this happens, please connect locally to the router's admin page (basically the locally connection page is 192.168.0.1 / 192.168.1.1 and use the Admin/password details which can be found normally on router's back label) and disable this function, let your Wi-Fi router operates on both frequencies: 2.4GHz / 5GHz.
That would allow the inverter to identify the Wi-Fi router and to connect to it and to the management system.
In addition, try to not use it as a SSID names with containing special characters (@#$%!*& etc.), it may cause problems when inverter will try to identify the Wi-Fi router.
If any additional information is needed, just send an email to eu_inverter_support@huawei.comwith the issue encountered and the serial number of the device and we will create a ticket case for you.
