Roof covering and solar technician selection - Decision?

Actually, black start means that the thing restarts without a battery. Otherwise, it would be empty after 1-3 days. The Symo GEN24 cannot do exactly that either, at least I researched intensively last year and found this function nowhere. But I am happy to be convinced otherwise.

As far as I know, it can. But I am also not 100% sure.

Fronius homepage: The GEN24 Plus is black start capable. This means that if the battery discharges overnight during emergency power operation, the inverter can still independently restart itself. The hybrid inverter automatically switches on again and supplies the household consumers as soon as enough energy is available from the photovoltaic system.

Yeah cool, then they were probably annoyed enough by email that it eventually ended up on the website. That you have to start the battery manually, I had already read that in forums.
