This will lead to some new and exciting ways of starting a housefire.

While the potential for fires shouldn't be dismissed, for batteries designed to be stationary rather than mobile (such as in an e-bike), you can use a chemistry optimized for stability rather than optimizing for compact weight and size.

Why bother? Power companies will complain they are losing money and regulators will allow them to buy energy from residential solar panels basically for free (NEM 3.0). This is California.

California has spent decades convincing people to convert to solar panels and EVs and now that many have switched, they doubled electricity prices and told us not to charge when it’s too hot. Now they want solar panel owners to pay a surcharge for “connecting to the grid”, upwards of $100/month or more than my actual solar bill. It’s all a scam.

How many houses in Britain have wiring that is less than 800 W away from starting a fire? How many of those houses have the disposable income to buy a plug in battery?

Yes, more electricity means more risk of fire. But 800W batteries do not seem like a major safety issue

If one is not modifying the house wiring how does this prevent backflow into the grid? Does it shutdown completely on power loss from the mains?

The standard governing this is UL 1741 in the US or VDE-AR-N 4105 in the EU. both require certified inverters to detect grid loss and immediately cut off.

yeah, it’s called anti-islanding. UL 3700 is the thing to look at if you want to read more about some of the safety precautions
