Will “X, Y, or Z” inverter communicate with this battery?

Current products supporting communication are all Victron equipment via a Cerbo-GX (via Pylontech communications protocol), MPP Solar inverters, Sol-Ark 5k, 8k, 12k & 15K, Growatt inverters, SMA Sunny Island (With appropriate setting changes).

If my inverter doesn’t communicate, can I still use this battery?

Yes, however you will need to manually set the appropriate settings within the inverter manually, and run these batteries in an open-loop, voltage control-based configuration.
