I have a Huawei solar installation but after spending some £20,000 for the installation in Spain discover it only works properly when their inverters (2) can communicate with one another properly, so it apparently needs a Dongle that is not advised by the approved Huawei installer prior to purchase. Any high usage or issue means the system stops altogether as it trips the main fuse box. After battling with the installer , I find it needs a Dongle (Smart Dongle -WLAN-FE). These Dongles cost about £200 but are just not available to any installer or anywhere all this year. Huawei do not even bother to respond to several requests for help on email over the past few months. I have ordered this particular Dongle direct from China, but doubt it will get posted as it was supposed to arrive this week and hasn't even left China yet, that's if it ever leaves. Huawei sell expensive product that even their installers don't know it requires a Dongle when 2 inverters are fitted, then fail to advise or respond when one seeks such a Dongle. Sent some 20 emails in all to no avail. You are left simply on your own.
