@BalooUriza @balkonsolar a grid tie inverter is synchronized to the grid and has to stop if the grid goes down, because otherwise it would loose sync and suddenly supply 100% of the load.
These imverters are designed to inject current in your home mains by using a voltage slightly higher than the grid, so it is consumed first.
@f4grx I'm trying to work out in my head how this isn't a "suicide cord" situation. I realize we're talking about differing electrical systems but to folks used to the power systems in use in North America and Japan, this just sets off all kinds of safety alarms in our heads so I'm wondering what's different that's making it safe?

@f4grx The part that I'm concerned about here is the graphic that seems to imply you can just plug this in to backfeed a wall socket that you'd normally use to plug a lamp or TV into, and that's the part that's specifically dangerous, since you're being a power source downstream of all of the safety systems, and people upstream can't guarantee their own safety from you when repairing downed lines as it works here when you just plug into a random wall outlet with a power source.

@BalooUriza
I might be entirely wrong but as I understand it they have pretty sophisticated current leakage and monitoring abilities and very very quick shut-off. So yes it's back feed but it can detect if something anomalous has happened so it locks out if a breaker is tripped or if a line is cut.
I don't believe you can use these in an outage situation, and you're correct it would be unsafe without an interlock.

@f4grx @balkonsolar@pfriedma That's what I'm saying,you'd need to have a cutover interlock at the breaker box, AND you can't just plug panels into any random outlet (since you would be bypassing circuit protection). I know that much from living someplace where my neighbor generated all the power for like 3 households and dealing with that, and still have capacity left over and still had a cutover to sell back power to the electric co-op.
Or is this just explaining modular solar badly?

@TechConnectify thanks for being on Fediverse.
@almino @TechConnectify I wish it was easy enough to upload to a PeerTube instance that Alec would choose to do so, for people that don't want to suffer YT ads.
But, the combination of so little reach and no (or even negative) revenue makes it hard to justify much, if any, effort.

I'm just at the start section and all of the benefits of solar bits I'm going "OK, this video isn't for me, it's an education piece for the dumb portion of the Americans and the UK Reform voters" but looks like I really need to watch the rest!

> six solar systems installed between 1987 and 1993 that have been in continuous operation since, and found most panels still producing more than 80% of their original output after nearly four decades.

@TechConnectify@cwilcox808 @mattesilver @TechConnectify that’s not universally true, though!
There’s a German electrician working on PV sites who’s documenting his attempts to repair a certain type of PV panel where the backside laminates deteriorate after only a few years… https://youtu.be/D-vWFO0gnUk to the point of complete loss of power generation because the isolation breaks down.
