Huawei Emma installation offered, whats the best?

[borgqueenx]

My installation comes with a huawei emma, if i decide to take it. Im wondering if its possible to connect to it, or should i rather connect to the inverter itself if that works? The installation comes with the newer luna battery of 6.9kwh.

I have been reading that the inverter can reboot if it loses connection to huawei servers? Is there a way to block the device from the internet all together? I am not comfortable with permanently running on chinese servers.

I am confused from the wiki about modbus installation and sdongle, as it does not say anything about huawei emma.
