> I think it can charge when power is cheap (or off solar if you have it), and then power a device (like a fridge) when power is expensive
Yeah that is a cool feature, but at least where I live there is only a few cents / kwh difference between peak and non-peak, which means this 1.6kwh battery system would save at most a nickel a day (~$20/year).
Good points, I want to clarify that ~$9874 is just the price of one powerwall alone. Add in electricians, wiring, permits and you’re looking at an additional $10k in install costs. Pila’s whole point is that it’s a plug and play solution with no install costs.
powerwall load capacity is significantly higher. pila could never come close to the sort of load that pw3 can sustain
meanwhile, i can find battery solutions that output 120v on aliexpress, for $700 for a 1.8kwh battery
anyways this show hn post is clearly an ad for a not particularly novel product. sorry plia!
Regarding cost, looks like this is $1k for a 1.6kWh battery. The Powerwall 3 is $9874 (plus installation costs) for a 13.5kWh battery. So Plia costs $625/kWh, while Powerwall 3 will run you $731.41/kWh. So it does seem the Plia is price-competitive, assuming my paragraph above is correct. And Powerwall will cost you even more than that per kWh since Plia is a self-install, while Powerwall is not.
Granted, there are cheaper options than Powerwall.
Plia certainly has its downsides: if you want it to power everything in your home, you have to put one (or more) in each room and plug everything into it (that's 8 or 9 Plias per Powerwall-equivalent). Presumably a whole-home battery can charge faster than a Plia, since you're probably plugging it into a 15A outlet where it'll be pulling less than 1800W.
