li bank in 2k modules with integrated inverter/charger

Hi Niner,

The power wall is not yet available for sale and the inverter is not included in the price. Apparently this competitor is already well established in Europe and has just entered the North American market.

Atries,

The unit can be configured to be run off the grid.

A little larger scale, for home use.

From the FAQ I gather they're grid-tie systems, which won't work in an RV. (Grid tie systems only operate when they're tied to the grid.)
