That's the Teslawall I mentioned. Basically the last home power storage option using Lithium-Cobalt batteries and doing all sorts of inefficient AC/DC transfers. There are a dozen options on the market now able to provide more usable juice out of less battery capacity, without using Cobalt (toxic AF, environmentally shit to mine as well). Been researching this because wife and I are looking to start building a house shortly after we move and I want to be as self reliant as possible because Mexico has gotten better in some ways, but it's still Mexico. Looking at 2 enphase banks for power barring something coming out better between now and then, and one of Watergen's systems that creates drinking water from humidity.
