Smart Home Battery Storage

As renewable energy / energy storage and energy security become more prevalent is bulb looking into a Smart Home Battery Storage solution?

By this, I’m suggesting a solution where “battery backup” is installed in a home, which is topped up during the “off-peak” tariff time, then used at “peak” tariff time as not only a way of lowering energy bills, but also lowering the peak demand on the grid.

Going a stage further would include the ability for power-cut use and utility blackout use - this being when the company uses the power stored to help power the neighbourhood as part of a local area microgrid strategy.

I’m simplifying it somewhat but its something I’ve thought a lot about recently and thought I’d put it out there.

Thanks,
Dylan
