Sodium batteries?

BTW that's the wish for trend line, $10/kWh right?

    I have seen some wild priced on Ali, in your link the 75Ah and the 210Ah are priced the same, so I guess it's for the smaller one, 30€ for ~0.225kWh or 133€/kWh.

    Could be wrong ofc, but it sort of fits what I thought it would roughly be.

    I mean even ~133/kWh..

    Whats an average, perhaps even gratuitous, level of consumption per household? 24kwh if you are running a clothes drier and an AC nonstop? Lets go nuts, say you are a DIY enthusiast and hosting your own servers, so 36kwh daily.

    3192€-4788€ to be and you can be effectively energy independent with a small solar system.

    Triple that and you are truly energy independent are any where south of the English channel. I mean obviously its money out of pocket, but its a fixed cost that you pay now, instead of a variable cost that continuously goes up. It just seems basic.
