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

Current products supporting communication are Victron equipment via Cerbo-GX, MPP Solar inverters, Sol-Ark 5k, 8k, 12k & 15K, certain models of Growatt inverters, and 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.
