This faulty reasoning is exactly why it is dangerous. If you have a 15A fuse, wiring is rated for a bit less than that as permanent load. If you have a PV feed of 5A in the circuit, consumers can pull at least ~17A without triggering the fuse. That's enough to start damaging the wires over an hour or two.

For the sake of argument presume this happens. There is a PV on a circuit that is already overloaded with sum of multiple loads across different outlets reaching 17A. 15A circuits in the US are generally fed by 14 AWG romex. The difference between 15 and 17 amps with this gauge wiring is dissipation of an extra watt per meter. This is not going to damage jack diddly squat.

In the real world if a circuit was overloaded in this way then it is going to trip after a couple of minutes unless it is only overloaded when sun is shining on the panels.

Not all anti-island detection implementation are the same. Some can detect parallel inverter, others can't.
Chances are high that the cheaper the micro inverter (and therefore the home PV), the less likely it is to

Can you name even one such "cheaper" micro inverter that does this?

actually be able to detect this case. Especially when mixing different models, things become out of spec very fast and anti-island detection is essentially the feature that keeps the upstream RCD working.

Multiple micro-inverters are commonplace. You are effectively asserting without evidence the technology does not work. This is what that type of failure you describe would mean.

Lets for the sake of argument assume what you are saying is the case. The solution is requiring home depot to sell listed solar kits that meet applicable standards (e.g. UL 1741 et el). In the US this may be necessary anyway due to state specific curtailment logic.

Millions of people all around the world are doing this sort of install and half of the states in the US have legislation in the works to allow it too. There is nothing remotely "surprisingly dangerous" about plugging panels into wall outlets.

That is your choice. You're the one who decided what to do with YOUR work.
Telling everyone else what they can do with what THEY created is not how it works.

Either way rights of individuals are being constrained by the states threat of violence. Whether it is the right for people to perform, reproduce or generate derivatives of works they encounter or the right to retain control of works you disclose publicly the state is restricting the freedoms of individuals. There is no preferential direction here that works one way but not the other here. It is only a balancing of competing interests thru the lens of subjective sensibilities of society.

How can you get people to agree to accept something when a significant portion of them do not agree on what the fundamental problem is? Or that a problem even exists? I absolutely agree with your sentiment, we would be better served advocating policies the majority of people are willing to accept. But sometimes the adults in the room need to stand up and do the right thing instead of the popular thing. So no, I'm not willing to compromise on the fundamental "excess carbon in our atmosphere is a hazard to our future existence.". Again, the "what should we do about it" is certainly open for debate, but you cannot have a constructive debate with someone who disagrees with what the problem is.

Reality and policy are inextricably connected. Someone who finds themselves annoyed by various taxation and zero agendas espoused by a political group they don't like is probably not going to sit around and dispassionately consider the facts to your satisfaction. The reaction you can expect will be closer to screw you and your little dog too. Denialism simply becomes the more expedient path to telling annoying people to take a hike.

The other issue is true believers have a track record of promulgating terrible policy counterproductive to their own causes. Some examples:

California rooftop solar mandate and NEM 3 disasters. Even if you think PV is great utility scale costs less than half to deploy the same capacity. Indefensible allocation of limited resources (not to mention legitimacy) to address an existential crisis while promulgating policy that causes an 80% drop in the solar industry.

Biofuels are a pointless disaster that in the aggregate emit more carbon than they save yet the insanity persists.

Proceeds of environmental taxes rarely ever spent to address climate change. Nothing says ZOMG we're all going to die like allocating funds to more pressing priorities.

Those seeking to limit use of natural gas in northern climates for the sake of electrification when it is guaranteed to increase costs and carbon emissions. Cart before horse is apparently too difficult of a concept for environmentalists to understand.

ESG has proven itself to be a comical failure.

There are a range of ideological positions on the topic of longtermism ranging from fuck today for a bright future to live today and fuck the future. For some facts simply are irrelevant because their value judgements differ so radically from your own. Agreement on facts before policy can be discussed is a fools errand.

Compromise on what? That pollution is bad? It's a fundamental question: Is continuing to add carbon to the system a good thing, bad thing, or neutral? This administration, against the feedback from the vast majority of the scientific community, has quite literally just said "nah, it's fine". There's no compromise to be made, you either agree on the fundamentals or not. The part to compromise on is the "what should we do about it?" question, but you can't even begin to answer that question until you agree on the underlying premise that we need to curtail our carbon emissions.

At the end of the day policy is the only thing worth haggling over. This notion there has to be agreement on facts or facts even matter is misguided. Few sufficiently care what is "good" or "bad" within the longtermist context of climate change for objective agreement to matter... Too far out, too abstract, too global, too costly.

Everyone would be better served advocating for policies most people are willing to accept.

42 USC 7521:

"The Administrator shall by regulation prescribe (and from time to time revise) in accordance with the provisions of this section, standards applicable to the emission of any air pollutant from any class or classes of new motor vehicles or new motor vehicle engines, which in his judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare."

In my view air pollution endangering public health is like inhaling lead, CO, mercury..etc which endangers the health of members of the public over time. CO2 doesn't do that at least not in relevant concentrations therefore I don't think this section should enable CO2 regulation for a different purpose of fighting climate change.

These schemes where people redefine terms and play games with no effective limiting principal to achieve a result even if the goal is laudable is still poor governance. Listen to the insanity out of the Trump administration being used to justify all kinds of crackpot insanity. Don't commit the same errors in judgement for a good cause. Pass a law and do it the right way.

There should be less deference to sanity of technocrats employed by the federal government. As we have seen with this administration that doesn't work. A major issue like CO2 has huge implications for industry and society and is deserving of political evaluation.

Thank you for proving my point. The most obvious danger is that a PV cell with micro inverter should be used on a circuit of its own, because it can prevent fuses from working properly. This is especially problematic in America due to the lower voltage. Let's say you have a 15 amp circuit and a 500W PV cell working at maximum capacity. If there are also consumers on the circuit, the wiring can be constantly overloaded by 30% without the fuse triggering. That's easily enough to create a fire hazard if the installation is even a bit shoddy.

AC circuit breakers and fuses in electrical panels exist to protect downstream wiring. They do so regardless of direction of current flow. If less current feeding an outlet is pulled in either direction a protection device need not trip. If more is pulled in either direction the protection device interrupts the circuit.

If current from PV feeds local loads thereby reducing current required to be pulled from wires feeding an outlet this would indeed allow loads to run on the circuit that would otherwise trip the protection device. This isn't a dangerous condition because the wires feeding the outlet are not being overloaded.

The other major safety issue is that non-electricans have a history of ignoring installation rules and wanting to install more than one PV system. Once you have two micro inverters, the island detection can become unreliable

This is baseless nonsense. Systems with large numbers of micro inverters are common especially here in the US due to requirement for MLPE stemming from 80v per conductor limit of NEC 690. Anti-islanding is a universal feature of all such devices. The kits come with standard electrical wall outlets and are designed for normal people to plug into an available outlet and have millions of installs.

effectively killing safety features like the RCD.

An RCD outlet on the same circuit works exactly the same regardless of the presence or absence of a microinverter on the circuit. If there is an RCD upstream of the circuit feeding the outlet then detected ground currents still trigger the RCD and shut down the micro inverter. You would have to check with the vendor for details.

"Buy a solar panel and plug it into a wall outlet" is surprisingly dangerous for a number of reasons, even more so if you have to operate on the assumption that the buyer doesn't even read the manual.

This is incorrect and is in fact commonplace in many countries. The panels include micro inverters that are simply plugged into common electrical outlets. The inverter has all of the necessary anti-islanding baked in.

App permissions are not a smartphone thing. They are a software thing. Smartphones were just quicker to deal with the problem of unwanted app behaviors, because they didn't have the decades of historical software that had to keep working.

What differentiated the smartphone from PCs is the app store. Bad actors get to leverage app infrastructure to globally cheaply publish low effort malware. Everyone else has to compete with "free" so everything becomes hostile to user interests. The whole system would completely collapse absent jails and permissions.

I'd like to see Microsoft expand this further, to all Windows software, not just App Store software.
App developers these days have ZERO regard for honoring the wishes of users.

Permissions are hostile to user interests. So long as software can normalize, retaliate or nag users to capitulate permission systems fail to deliver on honoring wishes of users. Instead they serve to protect the wishes of app vendors. With app stores OS vendor gets a cut of the overall pie and so perversions / user hostility gets baked into the operating system. Permission systems get watered down, basic controls for example controlling network access go missing. Solutions to these problems are systematically suppressed.

The solution to executing untrustworthy software is to run it in environments where access is never denied. In this environment applications have no mechanism to ask or even know what is being denied. User accessible settings control reality the app experiences which sometimes include spoon feeding apps bullshit.

What is needed for PCs is more accessible isolation mechanisms allowing users to separate workspace preventing unnecessary mixing of interests and separating low and high trust software rather than relying on access controls.

The costs in Africa are also far cheaper than in the US. A 5kW solar PV system with 5kW of stationary battery storage is quoted at USD $3,234 â" $5,390, which is far below the US cost, which is likely around 5x the cost.

Sizing 5kw PV /w 5kw storage doesn't seem like a good combo especially for Africa.

Equipment is cheap everywhere. Here in the US fully integrated batteries are $100/kWh. PV about $0.50/watt, or half that for used/bulk. AIO driving 5+kw of PV less than $1k. Everything else... labor, wiring, mounting, adherence to regulatory regimes all massively and unnecessarily hike prices into stratosphere.

Interesting for all of the talk about the environment and how important it is to curtail carbon emissions the US regulatory regime goes out of its way to throw a wrench in everything. From regulations against LSV to absurd requirements of NEC 690 and 706 that more than double cost while reducing safety. You would think people would be able to go to home depot, buy a solar panel /w micro inverter and plug it into a wall outlet to save energy but here in the US you would probably be fined or carted off to jail for that.
