In Europe we have plug-in batteries that just cycle PV every day to lower your electrical bill. But these are usually 2,5kWh or 5kWh.
In Europe you are hard limited to 800watt on a normal plug, no way you can do 2,4kW without a special fuse.
I don't understand this. It's a tiny backup battery with an expensive enclosure, with only 100W of solar input? How are you expected to run solar wiring with this in your living room? The places that can afford this rarely have power outages, so having an dedicated appliance sitting in your living room or kitchen for those 1-2 times a year doesn't make sense. The capacity is barely enough to run your fridge for a day…
Is this a product for the USA? Is the grid that bad to need something like that?
What's the use case here? Power outages? In Europe we have plug-in batteries that just cycle PV every day to lower your electrical bill. But these are usually 2,5kWh or 5kWh. In Europe you are hard limited to 800watt on a normal plug, no way you can do 2,4kW without a special fuse.

I don’t know where the 800W is coming from. It is quite common to have 16A breakers on a circuit. That is 3,8kW. My regular apartment has 3x20A breakers and for example my induction hob is 7,2kW two phase.
If you add the battery to a 16A circuit then you can theoretically draw 3,8kW + 800watt on it with the battery.
With this Pila battery you could put 3,8kW + 2,4kW on the same circuit!
If you want more than 800watt you can't use a regular plug in your house, it has to be a dedicated circuit.

Does the two-way meter have a way to prevent back feeding the grid in the event of a power outage? Having an unregulated device even under 800W seems like it could be dangerous to anybody working on the power lines.
> prevent back feeding the grid in the event of a power outage? Yes - such devices need a constant grid output to sync to. When the grid drops, their output drops. Furthermore, at 800W, it wouldn't be able to put any voltage onto the grid even if it tried to as it would get overloaded (it'll be trying to power up the entire neighborhood).
Judging by the negativity here you're going to be a massive success -- search up the dropbox, airbnb, coinbase and ethereum launch threads if you want to feel good about where you're at. :) That said, I like this idea -- a modern coordinated UPS. I live in an area where people have 3-10 days a year of no power; being able to pick and choose what power they'd use during an outage would be a significant benefit to them…

> Judging by the negativity here you're going to be a massive success -- search up the dropbox, airbnb, coinbase and ethereum launch threads This is not a new product, though. Battery power inverters with AC and solar input are a popular class of products. You can buy similar products with higher capacity and better solar input at Costco or Best Buy. I think people are confused by the "Show HN" tag and the misleading…
Here we are, rightfully thrashing a product because of disinformation, while we have a president product doing this on a global scale. Not a peep. It's always the little guy (with the exception of Google at HN) who get gets the flack when they do something wrong.
Misdirection is the most powerful political weapon, and we currently have a criminal making sure only he can wield it, with a fan base that loves the exercise of power, loves to see destruction, all in the name of (power to) Christianity. Christianity was losing so it got on board with a loser. No more "by faith" and "Jesus is the Lord". Now they cheer on the hole the USA is digging for others, only to fall in it themselves. Then "Elon" can save it and establish himself as the emperor of the world. The USA is just a pawn being played right now.
All this while we get upset with a small competitor and by the same rules we can't put our eyes on the big players. Dang, because we can only talk about tech. Well, dang, just make a section where we can go to make X-rated, tangential, comments. Because we sure don't want to go to X.
This is another Inflation Adjustment Act business if I'm not mistaken. Our tax dollars will pay 30% of the retail price to the company on every sale.
The ITC (Investment Tax Credit) doesn’t go to the company it goes to you as the consumer.

Do I have to point to 1000 failed Show/Launch HNs with negativity? This kind of cliched meta commentary whenever a Show/Launch is criticized on HN is getting really old.
Most (vocal) participants on HN that comment on product launches have almost no understanding of what will make a successful product / company.
I’ll put my money where my mouth is - check my comments on the ethereum launch thread.

I’d be interested in 2 or 3 successful show HNs that had positivity, actually, if you want to go searching. I’m not aware of any, and it would be useful to be able to better understand what high volume commenters on HN are good at assessing as far as product goes.

Most of them are overall positive, a few are overwhelmingly positive (it's true even when you exclude silly fun ones and focus on actual products); "had positivity" is such a low bar, it's absurd you're "not aware of any". Even this one has your comment at the top, apparently that doesn't even count as "had positivity" to you.
Moreover, even if 100% of Show HNs get 100% negative commentary, there's still zero logic in the statement "judging by the negativity here you're going to be a massive success".
Edit: Okay you said "successful" Show HNs. Then we'll have to argue about what's successful, and I can't be bothered. But you can go to the all time results instead and I certainly spot a few what I would consider success stories.
