Um, no. Remember, the grid is AC, not "one way."
Nice snark. I assume that you are implying the step down of a substation makes it "one way" even though you seemed to imply no house could feed PV into the grid as all houses feed directly to the local substation and thus burn off as heat. Around here, a substation feeds hundreds of houses. I will admit that my AC comment was a bit inane, but so is the idea that home PV feeding the grid is useless because the power system is "one way."
Your premise is interesting. I did not know that the power grid had this limitation. I would be curious to know what components restrict the flow of power.
Conductors, transformers and switches are not "one way". Power and current can flow through these elements in either direction.

Yeah, it's a bad design.
I think power systems should move to a cooperative type system.
Are our roads a bad design because heavy EVs are wearing them down more than expected?
If you have a solar array, and the power goes out, your power goes out - doesn't matter if the sun is shining or not. The reason this happens is because otherwise the lines are electrified. This is easily remedied, isolate the home from the grid, and excess power is simply not consumed by the inverter, and is dissipated in the panels.

Around here, that is a non-issue remedied by using a transfer switch. This old time device disconnects you from the grid when it senses a power line failure, just like when using a natural gas generator for backup power. Your house is still powered by your solar even after the transfer switch disconnects you from the grid.
In order for it to disconnect you from the grid you need an Automatic Transfer Switch.
Also, most inverters that people have on their houses don’t have “islanding” capabilities
But! But Tesla! <- is what our Tesla Fluffers on PatNet will say.
Heading them off at that pass: Fuck Tesla, this is an EV thread, not a Tesla-only thread.
Eh? Tesla would take about the same (or more, due to bigger battery) to fully charge on a 110V outlet. Not sure what's news here exactly. That woman being a stupid cunt who didn't do her homework before plunking down a chunk of cash?
Looking at $3-5k for electric install on top of overpaying for an EV.

Yeah, you need at least 220V on a 50amp breaker. The funny part is if you have natural gas, LED lights, efficient appliances, etc. you could power a 1,500 sq. ft. house on that. But that's what you'd need to power a car. Ain't cheap to run that at home either. Looking at $3-5k for electric install on top of overpaying for an EV. Talking a sedan too. CT or a Rivian would be even more. At least $20k in the hole.
How much gas is that? Oil change? All other maintenance is pretty similar. Maybe a starter or muffler. Still way cheaper for an ICE. Better range. Easier fill up.

I wound up behind one the Toyota hydrogen cell cars coming into my hood in Santa Cruz. I didn't recognize the nameplate, so I looked it up. They are still in the stage of being 'wealth show off and conversation piece' cars, I presume, before improving and becoming a bit more mainstream.
I know someone in South Bay who got Mirai. He is very happy with the Car for the last about 2 years. The drawback is, he can’t drive away from Bayarea and slight anxiety about running out of hydrogen.
August EV sales in Germany were down 69% y-o-y, and down 44% across the EU.
Wonder what they are for the US.

Electricity for much of the US and world is powered through coal, its just a switch to another equal pollutant. The batteries and materials used in EVs are full of heavy metals, not to mention that when the batteries in an EV combust they fill the air with pollutants, burning heavy metals that fire departments cant extinguish. Lastly, theres not enough data on current EVs to determine their shelf life, given the materials and amount of electronics, i imagine the shelf life of an EV will be significantly shorter than that of an ICE vehicle.
Given all of that, you will still be subject to the bitching and moaning of bugmen and babies who have never changed their oil in their life. The sheer panic that these people attempt to spread and their ever changing timeline of ecological destruction is obnoxious. These arent folks who attempt to clean up India or China(our leading polluters) but they want to concentrate on stripping you of your ability to choose.
The government is only too happy to comply too. The more that bloodsucking government can entangle themselves in transportation, the more control they have over you and your movement. The government gives companies like Tesla "Credits" that they can sell to ICE manufacturers who dont develop EVs, or dont develop them to the point that the government wants. This allows failing EV companies, like Tesla, to stay afloat even though they cant run a business efficiently. Honestly this type of behavior is more akin to a villain from an Ayn Rand novel, both with the governments overreach and with the behavior of many EV owners in general.
