DIY Grid-Tie INVERTER??

[Xringer]

The inventor (above?) seems to think I'm on the right track, in understanding the function of the flux capacitor gizmo..

Use a low voltage transformer that is UL listed. The circuit you connect to it would then be exempt since it is low voltage and isolated. (You might have to put the low voltage circuit in a separate enclosure for that to apply but I'm not sure.)

If the device shown in the video does indeed work and doesn't introduce garbage onto the sine wave,
it's very likely it would work just fine with a transformer. And of course be a lot safer to tinker with.

Maybe one of those old 20 pound low voltage/high amps transformers that most Hams have stored in the basement.?.
Used to be a lot of those around for computer power, before Choppers became so popular..

Tiny Grid Tie Inverter Unit, Maybe.
Not a very good design but it's a nice starting point.

There are a few DIY designs floating around on the web, but none with so few parts..
(And none so unsafe)!!

I'm too old to be working on that kind of stuff..
Just making mods to the stuff I already have is enough to keep me busy..

This thing needs a lot of work..

This could work. Great idea for the simplicity.

Triac are being trigered by the sector, and the capacitor bost the voltage of the battery up to the grid (Even if I doubt it can do it )

BUT !
If it work

It will distor the AC and introduce some mighty harmonics into the grid and your house

On a little scale that is not that bad, but on a higher level you may end-up having harmonics issue in your home appliance. Motor and transformer overheating, buzz sound in tv and speakers. On a event higher lever, you local power grid company may chasse you up for problem in neighbor houses.

As for the 100% efficiency conversion , this is bull****

What is the heat sink there for then?

Triacs will drop some voltage when current will pass true .6v to 1v typically
Voltage drop x current = watts dissipated it heat

No magic here

I'm really intrigued by this design ,,, I love simple design... I'll do a serious Microcap electrical simulation this week , I'll keep you in touch

I hear a lot about losses in things like SSRs, which I use for a lot of things.

I use large heat sinks most of the time, but have never noticed any
large amount of heat being coming off the devices.
Maybe I'm not running enough power, keeping things under 10 amps..?.

Here is a typical triac

Look at
Figure 9: On-State Current vs. On-State Voltage (Typical)

You will loose 1.1v at 10Amp

1.1v x 10 amp = 11w of heat to dissipate

After mutch simulation

This desing
RPM Independent Induction Generator

Just does not work

The triac firing could work , but no way it's gonna take energy from the battery to insert it onto the grid
