Anyone have any knowledge of the SunPower SunVault storage system?

My brother has a modest solar PV system from SunPower. It has 10 panels, I think they are 400 watt 96 cell panels with built in microinverters. They are very efficient, and his much smaller area of panels are clearly making more power per square meter than my system. They are still under the installer warranty for a few more years, so he can't really modify the system. He now wants to add some storage. He talked to the installer, and they are giving him a quote on a SunPower SunVault to add onto his existing all SunPower system.

I can only find some very limited information on the web. It seems their battery inverter is 6.8 KW and they off it paired with a 13KWH or 26KWH LFP battery option. I found this video from SunPower

Does anyone have any additional real world data on this system?

I just found a newer video where they open up the vault, it actually has a Schneider XW series inverter inside. Nice.

I like them. Recent update produces 6.8 kw continuous, 7.5 kw for 30 minutes, 8.5 kw for 10 seconds and 10kw for 1 second. Clean setup with the Hub+.
