bonsoir,

I'm going to read but in no way participated sorry I'm like who would say more than basic at the electronic level, I know how to make tin solder nice and clean, copy simple circuits use measurement instruments but not much more ...

hack
It's the same for me : Mrgreen:
A week ago, I didn't know how to operate a relay.
A month ago: schottky was russian for me.
But follow a tutorial to flash a firm xbox firm with resistance and inter I know how.
Emulate a wii reader with a computer via chip.
Replace the clapped condos in the flat screens.
Change the screens of iphones. Make a new DS with 2 dead.
Kids love it.
When we want we can.
Some minimum basics are required with a little dexterity.

Edit: little delirium: currently I am making a time machine door with recycled materials.
For the CM1 end-of-year film.
No battery. Solar + crank alternators and motors from everywhere. Lots of diodes ... : Mrgreen:

Yep it's clear especially that the comments of some worry me.
Just passing by at the time when I was working for the Bell Labs of ATT, the Asias that we received they had only one thing in mind.
How it's made? how is it programmed and what's inside the chipset? the rest they didn't really care. We see the result. I fear the worst for EADS and Airbus planes, I hope that some will not be in the air corridor !! This will be reversed because the world is made up of cycles. They are no exception to the rule. Patience.

At your place, yes. (whatever, the refusal of compensation from fire insurance is not made for dogs)

The problem is out of your house: if you put an injection inverter, it must stop in the event of a power outage so as not to electrocute the workers who work on the network.
And of course this characteristic must be up to standard and duly certified by approved organizations. But if your device works like that, if it is not approved, you are a potential assassin. : Evil:

Otherwise there is an armada of different possibilities, as Chatelot16 recalls, from the simplistic to the complicated, just enough to learn the basics of electronics, and this remains much infinitely simpler, than the smartphone, designed in the West and manufactured in Asia, with miserable wages, with, at the start, the simple law of induction followed by Maxwell's equations between the years 1830 and 1865:

Image
it's very simple, a coil and a switch at 30KHertz, which is childish at 1 Hertz with a manual switch, which from a battery of 4,5V makes you 1000V with a self of 1 henry (secondary transformer 220V ordinary low power) and which makes it possible to make its children feel the feeling of the electric current, but without danger, and which can be used as a defribillator in emergency, better than nothing at all by seeing die to resynchronize the heart:

http://sitelec.org/cours/abati/decoup.htm
http://fr.wikipedia.org/wiki/Convertisseur_Buck
http://en.wikipedia.org/wiki/Buck_converter

It is necessary to separate the DC voltage change and the generation of the 50Hertz AC synchronized with the mains with the safety devices.
read it carefully with the links in it:

Otherwise the Asia are as intelligent as us, if trained in the West, measured by their number of Nobel Prize winners of Asian origin !!
Also, even hiding the secrets, no hope, except to create faster than them, held back at home by their culture, their language, their customs.
They copy what they admire, quite often stupidly (example Chinese DSP!).

It does not go the head there.
For Cloclo, EDF was responsible? § it is not their fault?
For the High Voltage line of 20 K volt or 220 Kvot that falls on your head, who is responsible. Wind ?

Moreover it is EDF, who gunned me down the GTI following a micro cut of their network of M. during the light breezes of this WE !!!! And many more.

For the workers before intervening, they must ensure that there is no tension on the line otherwise it is tanpis for them !! When I worked on lines near the 400 KVolts and transformer their prevention plan was well turned in the sense that it was well done for your gu ... Must not mess around either !! I still find it very nice that you install a GTI in your house !!!! After your meter, that's their problem. It works in one direction so jurisprudence obliges in the other, it works in the other !! No but !!!

for the future Fukushima-Tcherno in France, inevitable sooner or later, since our nuclear supermans are not infallible in perpetuity, EDF is only responsible for € 9 per person, for 1 million people evacuated in one day a whole region, uninhabitable, incultivable, for centuries, even millennia !!


Moreover it is EDF, who gunned me down the GTI following a micro cut of their network of M. during the light breezes of this WE !!!! And many more.


It would not rather be micro-overvoltages, coming from lightning at some 100m, or neighbors with DIY GTI ???

Any commercial GTI measures the sinusoid. And only injects if it is present.
At each hertz it reverifies.
If no sinus-no injection. It's island mode.
For solar panels no risks they are grounded on themselves.
For the wind turbine: big risk of overload: so dump loader to unload too much.
