On 06 February sent this email to GE tech support…
“This afternoon while my solar panels were generating constantly and sufficiently to charge my EV the charging of my EV suddenly stopped. Generation was then exported to grid instead. Switching the EV charger off and on at the consumer unit made no difference.
Use of an RFID tag began charging the EV from solar and unfortunately the grid too.
Fyi both inverter and charger are each connected to the router by individual Cat 5 Ethernet cables.
To restore solar EV charging please advise next step.”

08 February - no reply from GE yet received.

Will the inverter still recognise the EV Charger if I Factory Reset it from the app?

I had that issue too

In the end, I had my zappi re-installed.
The Givenergy EV charger is flawed in many ways and I couldn't get the thing to run reliably.

Can you EV charge from solar with GE inverter & Zappi charger?
Which app does what?

sugarfree what settings do you have on ? It took me a while to get mine working but once it worked it's been good.

Not really answering your question but depending on your tariffs you could be better off charging your EV from the grid overnight on a cheap rate and exporting excess solar at a higher rate during the day directly or from your battery.

Yes, it all works as it should.
Solar charges the car when needed and battery also.

Although the aio still has issues in other respects.

Upon reflection, that's true!

Is your Zappi charger connected after the consumer unit (as with the GE Charger so the inverter recognises it's existence) or before (so the inverter doesn't know it's there)?

These working settings (prior to issue) are as per these two pdfs that I made for my wife to follow...

Are your settings something like them?
