The microinverters stop feeding in if grid goes down. So it's safe.

They are commonly used in many parts of Europe.

If you drop some Tariff percentages, we might be willing to advise.

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.

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.

Misleading name. These are basically all-in-one solar panels. It is much better to separate out inverters since they are scarce and expensive.

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.

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.
