Cheap Electricity Storage for Households Underway

[source] “MyReserve”, 93% efficiency. 4,4 kWh; 6,6 kWh; 8,8 kWh; 11 kWh units

Solar installation company Solarwatt from Dresden/Germany has announced that it will offer batteries for substantially lower prices in the Summer 2017.
Price 4.4 kWh unit: 5.499 Euro

German price context:

1 kWh from the grid: 30 cent
1 kWh grid feed-in compensation: 12 cent
1 kWh cost from panel: 10 cent

Under these (very German) price conditions does it pay to install this Solarwatt battery.

This btw is still a far cry from the promised $100-200/kWh.
