Yes, I agree that the Tesla webpage looks great and is targeted well to the residential market.
But Tesla and Redflow are targeting different types of customers and different types of installations.

If you read the recent investor presentation.
REDFLOW LIMITED (ASX:RFX) - Ann: Redflow Investor Presentation, page-1 - HotCopper | ASX Share Prices, Stock Market & Share Trading Forum
You will notice that the residential market is not mentioned. Therefore the marketing needs to be aligned with the target markets and projects that the ZBM is intended for.
In fact all of the pictures of ZBMs in the Investor presention lack cases except for the first page.
To me, Redflow is a company targeting multi battery installations that are housed inside of a building or steel container/shed. Not battery installations that require individual weather proof cases.
