Hi, had an electrician (not my Giv installer doing some work for a heat pump. He upgraded the fusebox. Powering back on the GIV-HY5.0 Inverter is all wrong.
The house is showing as no load and the imports and exports seem to make no sense.
First it appeared to be importing 9kw (pic 2) so switched everything on an off. That seemed to calm it but the battery appeared to be charging from grid (uninstructed)
I wondered if the clamp was not connected right ?
Anything I can suggest to the electrician in the morning or do I need to try to get them to speak to Giv?
its quite possible the CT clamp has been fitted the wrong way round, so grid export is being measured as import. Just unclip an turn it round, you can do this yourself
I suspect givenergy would say to get your installer back if this doesn’t fix it (at your electricians expense possibly) as its an installation issue
but try to CT clamp
look at the installation guide on the givenergy knowledge base
yes that;s the one. It explains where the CT clamp needs to be placed, but if your exports go up when you increase house load, the clamp is almost certainly the wrong way round. There is an arrow on it, but just unclip it, rotate 180 degrees and clip it back onto the supply coming from the grid
I am afraid it says something about installers.
The electricians and often contracted in.
They know about electrics, but not about the nuances of renewables.
What happened to testing to see what they have done actually works?
When my system was first installed, I had a zappi added and the electrician connected one CT the wrong way round.
When there was excess solar generation, the CT clamp showed the grid sending electricity to my panels!
Hopefully @geoffrey 's suggestion will sort out your problem.
