Hi. You missed one point. At 4:05 it is not clear how to "stack them together". And the Internet keeps a silence. Are there any other methods to stack except a simple low Ohm resistors? I cannot imagine how a boost converter can measure a merged voltage and control each individual MPPT, so panels will share their output. If we simply twist the wires to make one DC rail, the strongest converter will always win, and one panel will always be loaded at a max, and some of them won't output at all if the maxed output is enough for a load. It would be great if you create a video about methods used to combine DC or AC outputs. Thanks.
Explain about U V W output investing pulse. We are given negative voltage in source but it generating negative pulse in output section explain about IGBT output UVW motor output pluse
4:14 400V is very dangerous stuff. it can cause an arc flash and evaporate you entirely (check videos on youtube, people is literally evaporated during an arc flash). I use 24V (well, that would be 28V due to LiFePO4 chemistry) for my battery bank and I step-down solar panel voltage to 29V for charging them. I have thought of going to 48V , but decided not to do that because 1) electronics below 36V is cheaper (35V capacitor is used everywhere) 2) 48V is not a safe voltage for humans I have thought of changing my solar system to 48V , it would be more efficient, but I decided not to. I prefer pay for safety with lower efficiency. Once I connected a buck converter to one of my 900A battery banks, but I incorrectly connected it (reverse polarity error) , well the components of the board fled away from the board in pieces (they were un-soldered instantly) when I did the "spark test". This was my first real arc-flash (at micro-scale), and I would say it is a horrible experience even if was that tiny. I can't imagine an arc-flash at 400V, it would be like an atomic bomb explosion. If you are doing a DIY solar installation, I don't recommend 48V , 70V or anything higher than 24V system. Because if you are DIY-guy and you love wiring your own stuff, you will 100% (some day) wire something to the battery with the polarity being inverted, and if there is lots of copper on the board, it will blow like a bomb with some parts of your body evaporated.

Please make a video on how we can make a mppt charge controller

Every single SMPS you see uses 400VDC if it has a PFC. That's a standard value. So, relax
If any doubt about my question plz ask in comment... Plz explain clearly
