BYD B-Box LV Residential Limitations
The main con for the BYD Battery Box is that they are quite large and clunky, making the battery system seem a bit obtrusive. The optimal temperature range also makes the B-box a less-than-ideal option for extreme climates.
They will also need a compatible hybrid inverter to work. There are several compatible converters currently including SMA, GoodWe, SolaX, and Victron. The correct inverter will allow DC coupling to solar and backup power during blackouts. It can also be AC coupled, although this makes backup a lot more complex.

Reviews from Australians who have installed BYD Batteries
Just works well and is tiny given the power and output. Safer than the Tesla and actually works during an outage with the panels too, another main reason why I chose it and the Fronius Gen 24. Looks dapper too!
Matches well with Fronius Inverter
Battery Box Premium - Classed 3rd best in Australia
Happy to see what we are doing with our power and we never ran out of the Battery yet.
The batteries look and function great. I hadn't heard of BYD previously but wouldn't hesitate to install them again.
Fine to date
I had a failure with the battery BMU and the replacement service was excellent.
Poor storage given overall system poor performance
Solar batteries are very useful.
