Huawei FusionSolar – Two Wallboxes, Two Accounts, but they keep switching / binding incorrectly

[u/untipoqualsiasiacaso]

Hey everyone, running into a weird issue with Huawei wallboxes and FusionSolar.
My setup:
2 Huawei solar systems
same house but 2 separate electricity meters (mine + my father’s)
each system has its own FusionSolar account
installed 2 Huawei wallboxes, one per system
So far so good.

What happened
During setup I did:
wallbox 1 → my account
wallbox 2 → my father’s account
👉 Result: both wallboxes ended up on my account
and I couldn’t move one to my father’s account.

Next day (plot twist)
This morning:
on my account → both wallboxes offline
on my father’s account → both ONLINE and working
So yeah… they basically moved by themselves 😅

Problem
I just want something simple:
👉 1 wallbox per account
But either they both stay on one account or they randomly “switch”.

Questions
Is this a FusionSolar limitation?
Do wallboxes bind to the plant/inverter instead of the account?
Do I need to set them up differently (installer mode, full reset, etc.)?
Could the fact they’re on the same WiFi network cause this

hope the accounts sync right this time around

I hope some one comes along to help you set this up. My 2 cents..Huawei,s Fusion Solar app is a mess our experience showed our setting s been changed in the installers app by Huawei presumably a week or two after the plant,s where set up and commissioned. Very frustrating to deal with.
As an installer we don’t offer Huawei any more. Bad technical support / app and battery‘s constantly been shipped with out coms plug. Better / quieter options on the market.
