Is there any reason this won't eventually be commoditized?

The retail cost (low end) for lifepo4 batteries is $125/kWh, and for hybrid inverters it's $175/KW, thanks to decades of Wright's Law.

Currently Pila is $625/kWh, but what is stopping it (or clones) from being $200-400/kWh eventually? Their high prices are probably temporary artefacts of (1) lack of current scale, (2) premium due to UI/brand/lack of competition. But markets will catch up.

If the price does drop to that level then it's a big deal because you don't have to pay labor installation costs, which is a large proportion of total costs for end consumers.

The main question I'd have at that point is about electrical and fire safety relative to the standard setup.
