Yup, Growatt is the Chinese OEM that Base Power white labels to pretend it does US manufacturing. In fact this stuff is low quality. You need to be careful. There are gradations of quality at cell, pack, inverter, control levels. You will be crushed if you realize you AliExpressed your way to a home power "solution" only to have it fail young.


For what it's worth, Tesla PV/batt inverters are bad, almost as bad as the Chinese manufacturers mentioned ITT. PW3 has very high failure rate ~10%+RMA, not good enough IMO to be in the path of power at my house.

(Their motor inverters are world-class, but totally different topology)


Tesla Powerwall products (including Powerwall 3) have a massive failure rate. Seems like 10% over lifetime. Shoddy technology compared to the leading competitors, especially the inverter. They should go back to white labeling cheap Delta inverters.


In the industrial world, where the real money is to be made, a high failure rate of the individual units isn't an issue.

You simply overspec the site by perhaps 2% to allow 2% of units to fail and the whole system is still working to specification.

Then you design the replacement procedure for the battery or inverter modules to take 10 seconds per module and swapping the faulty ones out only takes a few man-hours per year even for a gigawatt scale installation.


exactly right -- although tesla is weak on power electronics for the industrial scale sites, too. there are SPOFs there in the power conversion chain.

but a DISASTER in residential.


Of course, Sourcegraph is better.


What does Amp do better than Claude Code or Codex? I find the concept pretty appealing but the pricing is a bit scary.


It has better search and context management under the hood, which matters for big companies.

But you can also see quantitatively that Sourcegraph produces the most accepted code: https://www.theinformation.com/articles/openai-catching-anth...


Well, that's certainly something I care about. I'll give it a try, thanks!


These are forcememed companies, unfortunately. Neither Palantir nor Anduril make a single thing that China doesn't, and neither one makes a single thing at attractive cost that would intimidate China in a conflict. They could disappear tomorrow with no impact to US military lethality.


Based on my direct personal experience, this is a counterfactual statement.

It's sad when partisan politics so overwhelms discourse that people just make up nonsense because they don't like the CEO of a company.


“I personally don’t think that’s true, and it upsets me you believe it’s true” isn’t really an argument though.

What are they making that would intimidate China, that China doesn’t already?


Combat-proven software that helps put warheads on foreheads in compressed timescales. I'm not talking about development projects or what could happen, I'm referring to applications that are being used right now.

There's a massive difference between something in a lab or in a paper presentation and code that is running in production and provably works. There are lots of individuals pushing up daisies that would attest to the effectiveness of Palantir's applications if they could still speak.


Dude, gross. You don’t have to talk like that.


1) lol 2) source for such confident claims 3) even if true, can they potentially make existing tech cheaper than competitors? Competition is good for price. If so, still an "impact on US military" 4) see 1.


Source?


EVs with BrakeFlow resistive protection against thermal runaway also will have a big impact –– allowing for faster discharge into the grid. Increasing cRate for grid services can "bring forward" the point in time –– so 2030 could even happen a few years sooner if these high performance batteries from Enovix come to the EV market soon.


Same reason internet bandwidth if more abundant and cheaper than ever, but your Comcast bill seems to actually only go up.

Local rooftop solar, with no reliance on utility monopolies, is the most important thing in the global energy picture, and I'm afraid it isn't even close. And I'm pro nuclear. But it's past time to recognize that it's the distribution monopolists that are the problem. Solar and batteries free you from that.


That is what 5 year olds around you understand?


Yes, I violated eli5 rules. Sorry


Let’s stipulate that I don’t know why broadband bills are getting more expensive, if you don’t mind.


https://arstechnica.com/information-technology/2021/05/ajit-...

The phenomenon is that consumer prices for broadband go up, even as the wholesale cost of bandwidth (what Comcast is reselling to you) goes down. The cause of this is a mix of two things:

1. Cable companies have regional monopolies. Without a choice, they can raise prices on consumers without losing customers

2. Cable companies face ever increasing 'infrastructural' costs, such as environmental review, trenching, construction, permitting, easements, etc... These costs are well established as going up in excess of inflation (part of why we can't build new infrastructure anymore) and therefore even while the product itself (internet access) gets cheaper, the 'last mile' of distribution keeps getting more expensive.


Forgive me but I’m not understanding the example. Would you mind explaining why this comparison is valid for renewables but not fossil fuels?


Does anyone have any good articles about AWS (or other) lock in? I have Matt Prince's article about egress fees, but I'm looking for something more thorough.


Most (on HN) are just people who misunderstand the cloud business badly or think their case of reinventing the wheel can be applied globally.

You can do a site search for hacker news with just one of the cloud names in it to find a ton of blogs about it.

Most of them say "lock-in" but aren't actually about lock-in because you're not locked in, just in a bad position (power vs. utility).


Real science investors with access to high level nuclear talent never seemed to think much of this company.

Its financing seems to be Koch Industries, through a strange sort of PR/VC arm they have.

The denial is substantive. I am pro fission but, erm, would rather go with Westinghouse.


You don’t sound pro-fission. This is a novel 1MW micro-reactor with major policy implications that merits public support.

Westinghouse and other large reactors have a totally different use case thank Oklo’s design for remote communities.


No, Westinghouse has designs for small reactors too.

One prob with oklo seems its amateurish funding and founding. The other is that maybe 1 mw isn’t so useful. 100mw makes a difference (with distribution), so does 50kw (without distribution.)

What is 1 mw for? An airport, maybe?


Many are not lawyers at all, as is the case here.

What gets me is that amazing innovation was taking place, and privately financed. CA households were themselves paying out of their own pockets to build the huge additional capacity needed for EVs, for instance. All that rooftop solar really adds up. It also makes PGE's job much easier. They barely have to lift a finger these days when it's sunny and not too hot.

But PG&E and its uniparty allies like the NRDC just couldn't have it. They want control. They can't support distributed, renewable energy, because it cuts their (very badly maintained and undeserving of support) monopoly on distribution.

Classic CA decision that only serves PG&E and insiders, not the people.

Needs to be reversed by the State Legislature.


I don't particularly like PG&E but you're misrepresenting the situation. They have to lift a lot of "fingers" when it's sunny in order to keep their portion of the grid stable. Unlike base load power plants, the power supplied by household solar panels constantly fluctuates. Some sort of grid scale storage might eventually solve the problem but for today that doesn't exist.


Honestly, no. PV does fluctuate, but at PG&E scale, the fluctuation is (a) smooth and (b) predictable. Demand for energy is going up, but demand for PG&E's brand of energy is going down. But state law guarantees PG&E revenues. That's the reason for these anti-consumer moves.

In any event, surely you agree that state granted monopoly utilities are public services. They're endowed with a monopoly to serve what the people need. PG&E seems to believe it has a right to live perpetually in... I don't know... 1988? But it doesn't.
