This is a most excellent place for technology news and articles.

That's what I have. Basically a small-ish parallel electrical system that runs critical loads like a mini split, refrigerator, water heater, etc. And a small UPS for modem/server.
Out of curiosity, how do you have that setup (at a high level)?
I've got a bluetti system for emergency power (12kWh, 6kW AC output) but I need to plug things directly into it. It'd be nice to feed it directly to my house wiring but ... selectively. That is, I wouldn't want to power the HVAC but it would be nice to not have to shuffle the fridge/freezer plugs from the wall to the inverter.
Dedicated circuit(s) with a manual switch from mains to inverter, I'm guessing? But then we get into all the extras required to do that safely and avoid back feeding the grid.
Granted, they have systems/setups specifically for whole house power but I don't want to feed the whole house, just the important circuits/appliances.
Basically made a really sturdy pergola and then mounted solar panels to it. Ran that wiring to the MPPT, batteries and inverter in the garage. Put in a new small breaker box right next to the existing one, which made it real easy to just grab the wires for the critical loads and run them over to the new panel.
No need to worry about backfeeding, as I said they're parallel electrical systems, so it's not possible.
My thoughts exactly. Also I wouldn't really like to risk my stuff by connecting to their infrastructure anyway. At least over here, I saw how incompetent they are.

If your business is critical for modern human living, it should be non-profit. It should be guided by the best management plan of the time, debated and approved by the majority of shareholders. It should open its books and stay open.
Really, it should be government.
My power company is a co-op. They have long term contracts with various providers, so my power bill doesn't fluctuate much on short term news.
At the end of every year, we get a dividend check in the mail for any excess profit.
Pretty sure all utilities should work that way.
“Non profit” “shareholders”. Pick one.
I assume they meant stakeholders...cuz like yo, that's us!
Why don't we just change the revenue model for power companies. I understand they need money to maintain the infrastructure and pay employees. If power generation becomes so cheap that it can't sustain the company then don't rely on that for revenue. I'd rather pay a flat rate for the infrastructure and operating costs than a fluctuating generation charge. And public utilities should not be for profit.
Many places already do charge a “line charge” if you have solar power and use little or no utility company power. You pay for being hooked up to the grid even if you barely use it.
When I got solar panels on my previous home there was a $5 a month line charge. That when went up to $8 the next year, then $10, then closer to $20. The power company (Duke Energy in case anyway wants to the shitty company's name) was determined to make it as painful as possible for people to use Solar. They were also apparently responsible for pushing to get it illegal in that area to go "off grid" and to have a cap on the amount of solar power a home could generate. At now point did these line changes stop them from raising the normal power usage rates mind you, this was just an extra "fuck you" from them.
If power generation becomes so cheap that it can’t sustain the company then don’t rely on that for revenue.
I'm not aware of anywhere power generation is that cheap yet. That may be a problem for the future when commercial fusion is viable, but thats likely a lifetime away.
I’d rather pay a flat rate for the infrastructure and operating costs than a fluctuating generation charge.
I think everyone would, but the cost for generation is always fluctuating because the variation in the market for the fuels that generate electricity, supply, and demand of electricity on the market. If its a flat rate, and that rate is below the cost of generating the electricity, who pays?
I mean, it makes sense to me that consumers can't be pumping energy into the grid with no way to cut it off, but I'm not a lineman or some sort of civil engineer or whatever.
But if I were a lawmaker, I'd be on the phone with the Germans, who have 1.2M of these connected, and figuring out if and how they're doing it safely. But lawmakers seem to be somehow incapable of reaching out to people who know fuck all about anything.
I had a chat about this with a friend who works for the national grid (UK).
Apparently the problem is keeping the grid balanced and stable. Basically, the grid struggles to react fast, so they plan ahead. Things like large scale solar can provide predictions on output. Home solar can't.
When clouds pass over an area it can cause slumps and surges in the local grid. The more home solar, the worse it gets. The current grid is designed to work top down, with predictable changes in demand. It needs upgrading to deal with large scale bidirectional flows.
The plug in units are (potentially) even more ropey. If used properly, they are no worse than normal home solar. Unfortunately, being cheaper, there are worries over the microinverters not shutting down. Either due to the manufacturer cheaping out, or turning on an "off grid" mode.
There are also worries about overloading household circuits. Back feeding bypasses the household circuit breakers and RCDs. They could overload wall wiring and cause fires, or stop an RCD tripping, allowing for a person to be shocked.
I don't know how much this would apply to the American Grid, but I would imagine it would be worse. Your grid is older and larger. You also use 120VAC which makes the current overload issue a lot worse.

Voltage inside of residences is 120v AC, but its 240v thats delivered to each house. I think a bigger difference is that in the USA that 240v AC is single phase where I believe (Germany included) many nations in the EU are 3 phase.
The USA does have 3 phase power for most commercial applications though.
These systems are designed to not push power back up if the grid goes down. In most areas, the municipality won't even allow a solar installation to be connected or even finished without it being inspected to verify you have that sort of setup.
In the US, reaching out to other countries for advice, even if they're our allies, seems to be viewed as treason. At a minimum, seems like treason against "real" masculinity, on which American culture is fueled, especially now.
