It depends on the settings. In normal mode, the wallbox is like a normal device and can therefore also draw power from the battery.

I don't know the answer to Cinzia's question.
But I do have a question: I've lost an RFID card supplied with the Huawei kiosk. Huawei support is not responding.... Does anyone know how to find a replacement card AND get it recognised by the kiosk?
Thank you

No. It is best to install an EMMA from Huawei, which optimises and automatically controls everything.

Yes, when the battery is charged. Must be set by someone who understands changeover alignment! is not that easy.

In >FV preferred< mode, the system first charges the battery, then the excess production is directed to the car, using part of the previously stored energy. There is no direct transfer from the home battery to the car, but I still highly recommend it if there is already a Huawei PV system.
