I'm in the same boat - I've got the 10KW MIN inverter, and would love to be able to add batteries in the future. I'm definitely interested in any progress you might make & would be happy to help out in any way that I can.
As someone with a Growatt MIN10000TL-XH-US that supports only Growatt's (very) expensive HV batteries, it'd be nice to see more HV batteries available!
