Grid Tie Inverter Diy - how to reduce your Electric Bills

Tue Jan 31, 2017 8:17 pm

Hi Guys, I think this circuit diagram is worth to share with everyone. This is 100 percent working and make your kwh stop from moving...and move backward.

Components:
1. Big Transformer 5kva [Secondary 110-0-110],[Primary 6-0-6, or 12-0-12]
2. 4Nos. Transformer 1 Ampere [Primary 0-220][secondary 0-9]
3. 4Nos. of IGBT Transistor[ I'm not going to give specs. Do some math.
4. 4Nos. 1/2 watts resistor [ i used 1k, but do some math] 1k works for me :).
5. 8Nos. Zener Diode 15VDC/1watt
6. C1(100uf/450DC) for Secondary Capacitor and the coils are line filter

* Don't operate the grid tie without secondary supply the Input DC come from Solar, Windmill...etc

This is the actual circuit layout for the power and control transformers.

The control transformer is shown as a single unit with 4 isolated secondary taps. However 2 transformers with dual isolated secondaries or 4 single transformers will work too. The control transformer assembly is a voltage source only circuit so very small transformers can be used.

The small round dots on the power and control transformers designate the phase relationship between each winding.

TR1 and TR2 control the actual transformer connection with the AC line.
TR3 and TR4 are optional for a single line source system. They are only needed for a dual line American style 120/240 volt system.

TR1 -TR4 are actually solid state relays but can be mechanical relays instead if the drive signal from the control circuit is designed to work with them.

D1 -D8 are 15 volt 1w Zener diodes. These are to prevent the switching devices from getting too high of gate voltage. They should be mounted as close to the switching devices as possible!

Q1 - Q4 can be single high amp switching devices or several single units in parallel at each corner of the H-bridge circuit.
Q1 - Q4 can also be a pair of half bridge units as well.
The actual components and layout are up to the builder.

X1 and X2 are opto coupler driven SCR's but they too can be replaced with mechanical relays if the control circuit is designed to work with them.

Some are suggesting that the best way to reduce electric bill is by building self power generator, or a pure magnet motor...!

The magnet motor is a kind of difficult to make ....and expensive to work with. But this grid tie inverter...is 100 percent successful. i TRY THIS DIAGRAM and im very happy with the result..the kilo watt meter actually reverse... the more power i send from grid tie inverter the more i get positive result.

Use - 4pcs of 9volts/ 1ampere transformer in TR2
