I am sorry but I was hoping for more technical details. What I am interested in is not only about the actual electronics that achieve phase-matching, but also how a pure sine wave is electronically generated from a dc source. I was disappointed. >

(2:10) - This illustration suggests or implies that adding two ac identical voltages in parallel, of the same frequency and in phase, doubles the voltage. This is not true. Now I do know that you would double the available current, hence the power, but I do know that connecting identical voltages in parallel does, or should not change the resulting voltage. How so ? I'm confused. >

I often wondered about the switching of the DC supply. Simple on off is easy but to completely switch polarity at the same rate got me puzzled. What such a simple solution as taking the centre tap from the primary transformer. I'm still trying to figure out why I didn't think of that before now. >

any comments regarding a cheap grid tie inverter for example this type: www.banggood.com/600W-2260V-Solar-Grid-Tie-Microinverter-Inverter-MPPT-Pure-Sine-Wave-120V230V-p-1104831.html?rmmds=search
Can someone tell me? I voltage from grid is 230v then after synchronize the voltage from inverter so will it increase to 460v? I dont get it that you said 1 plus 1 become two not sero.

Actually he said it totally the other way around. If they are in-phase the current will not flow at all. If they are in-phase but the voltage from one direction is higher than the other then the current will flow from higher to the lower voltage. But of they are not in-phase then will be an explosion because there will be too much current flow from the grid to your system, and the job of the grid-tied inverter will not be achieved.

At what point will the voltage be higher at point so that current flows? Will the grid tie inverter generate higher voltage?Thank you in advance!

@simonmccaughey

kinelapo that is a great question, and in my opinion one of the most fascinating things about grid tie inverters. As far as I understand it, the inverter pushes the phase a little bit, so it attempts to go very slightly out of phase, and if the grid is connected it resists this push. Essentially the grid is like a big flywheel that keeps the phase very steady, and the little inverter has no chance of changing the phase of the grid. In the case where the grid is no longer there, then there will be no pushback from the grid, and the inverter knows that the grid has gone, and can shut down, until it senses the grid voltage again. All very clever. I’m not sure how often this test is performed, but I imagine it is very frequently.

Good video but you never explained how the inverter actually gets the true sign wave. You said the normal inverter rapidly switches back and fort and it produces the square wave. So how is the Sine wave actually got.

Thanks I just helped my Niece to understand the inverters using your video. I was technical( going to deep in to MOSFET's and IGBT's -advantages/disadvantages, why MOSFET's are easier to switch on/off and so on and the beauty of MCU to control it). I did not understood that she did not understood that basic principal of DC and reverse polarity. Could not understand where I was getting the - voltage in the sine output. The battery and voltmeter reading made her understand. Cheers

I think the solar or wind..whatever the DG it may be, it will energized even tough it is disconnected from grid...says IEEE 1547 standard. That particular Islanding condition must be detected and DG has to disconnected within 2 secs, otherwise it would damage the equipment and might be harmful for technicians who're working on transmission lines..
