Sorry to say never properly resolved so I returned the unit to Amazon and got a refunded

purchased – https://iotawatt.com/
which is better as all data is locally stored with no need for cloud access

IGNORE THE ABOVE

I miss interpreted who was eating data – it was my PC which suddenly divided it needed to refresh 95Gb of google drive data – but did not do this in one go – it sort of did it in chunks

Does you car not tell you ?

With a little bit of fab support this has now been resolved and we have it working as I wish

great job to the support team at Emporia

Can I suggest you do a Passive House Calculation – look at saving energy before replacing a heating unit

thanks – here in Ireland (same as UK) 240V single phase to the house

RCD was tripping on first install

as suggested – there are two neutral buses – one direct from grid – a second downstream of RCD (or whatever they

are called nowerdays)
connecting the black lead down stram of RCD and the others on the grid tripped the RCD (i.e. working as it should)

so thanks for the fix above – all working now

cannot edit previous post – not actually working
I thought it would but it gets confused when the PV is supplying more than the house needs so across clamp B you have say 5kw – house uses 3kw should allow clamp A to show export of 2kw

any advice if I can get this working ?

Here is a diagram showing what I’ve done – and it works

Mains can feed house and/or PV/battery

VUE does not give PV / battery stats but you get that from the Huawei Fusion Solar tool

This is a 250V – single phase system – based in Ireland

(No re-wire needed there was enough slack in the fuse board to accommodate what I wanted to do

I think I might have answered my own question

I think I need to use one of the 200A clamps and configure my wiring so that

Clamp A goes on the inbound from the grid

Clamp B goes on the inbound from the inverter

 

To do this I will need my electrician to do a minor bit of reconfig in the box

Here in Ireland not like you have shown in your diagrams, things like PV need to be inside the master breaker and inside their own breaker

So I need to be a bit clever and put Clamp A inside the master breaker on the lead to the other circuits but not on the circuit to PV/battery and Clamp B on the feedback from its own breaker

Before I get the electrician back can you confirm?
