Redback Hybrid Inverter - Australia

I've already got a 6kw solar setup with a SMA Sunny Boy grid tieinverter. I think the standard route for adding battery with these is to link the Sunny Boy with the SMA battery inverter - Sunny Island. All added up, that's a pretty big expense before the battery cost.

I was thinking about adding a PIP and batteries for maybe one power outlet circuit ... but then saw these:

I might be better off selling the SMA and putting one of these in when I have enough battery to make it worthwhile. I'm having trouble finding the retail pricing for them, but from a couple of articles I think this whole unit costs less than a Sunny Island:

* Multiple battery chem
* Grid export
* 9.5kw grid pass through
* Seems to have lots of programming options
* backup - house can stay powered when the grid goes down

Hybrid is what i Use to but other brand. There have started to come more and more. From around 2000eur for a 10kW system without batteries.

I've gone off the Redback after a bit more research. They withdrew all official support for any batteries except LG and Pylontech in May this year... AND you can't change any settings without an installer account on their cloud platform. It looks nice, but ... no.
