The new sodium batteries are a lot safer than the lithium chemistries. And we already do have type of home batteries they are just called UPS systems. The real game changer will be when 3-5kwh plugin batteries fall below $150-200pkwh as at those prices batteries will make sense even for apartment owners/renters with no solar to use it to demand shift as time of day electricity prices get more common.

The problem isn't the battery catching fire, it's that you no longer have a circuit breaker between your appliances and the generator. Meaning you could, especially if you have several batteries, push load through wires in the wall in excess of what is rated for.

it is the same as the balcony solar though so what is the difference the batteries would be doing the same exact thing?

[gambiting]

Maybe you don't know this, but in the UK every single appliance has its own individual fuse right inside the plug.

You can have multiple loads and sources that are in-spec but the wiring between them is overloaded.

Why that number in particular? Are you thinking of payback period of something else?

[xbmcuser]

Yes payback period batteries as at those prices payback period falls below 5 years with just 4-5c arbitrage so even if you don't have solar like most apartments it is still useful. And the price is low enough that it can be made mandatory for all new home construction without inflating home prices.
