Yes, Gen24 with BYD HVM 22.1 and PV Point. I've actually never tested how the UPS (EATON Ellipse PRO 1200) likes the PV Point. I am aware of the Frequencies when in Backup mode. I don't know what full backup solution the electrician would offer, but it would cost €700 including work. The real problem that makes it so much more expensive, is that my distributor box is full, and the solution needs 17 more slots on a DIN rail. A lot of work and a a couple of hundreds for the hardware.
