This was the group who did it for me in Australia: https://voltxenergy.com.au/

It was under subsidy, but I got about double what I was going to get about 6 months prior. There are 50kwh units going on AliExpress for about $12k AUD outright so I think there's been another step down in per-cell costs which is tickling through.

I'm waiting for a price cut to make outright purchases a bit more affordable but with a wholesale electricity service plan adding another say 100kWh probably works out.
