All in one? 
Yes  - hybrid possibility (AC, DC, AC-DC) (Storion-SMILE-B5-GW 4.6kW)
No
AC: when you already have a solar PV installed. Can function regardless of the type of solar inverter already installed. 
AC coupled - requires solar inverter  (can charge from the off peak grid)

DC: Built in 4.6 kW hybrid inverter. Meaning you don't need an inverter when installing solar panels & can provide backup during a blackout. 

Warranty
10 years performance, 5 years product
10 years at 70% capacity if charged solely with solar power
or when reached 37MWh (3,200 cycles, around 8.8 years if cycled once a day) of stored energy if also drawing energy from grid.

Comments:
- Origin Energy installs the Tesla Powerwall from $15,995 incl. GST. The Alpha ESS 11kWh costs around $12,000-$13,000. 
- Alpha is AC and DC-coupled, Tesla is only AC-coupled and needs an inverter. See below and in table for difference.
