Hi all
The video posted as the subject of this discussion was posted on YouTube by myself. Ask any additional questions. It is good to see some here have come up with similar possible solutions as I was thinking such as voltage triggered SCR or something like that. I will be investigating these...

I did this for a bit. I used igbt switching at 12k with a drive of 12v. Real simple Arduino voltage comparator. I got a heap of Rf interference, however the grid tie inverter seemed fine with it. I kept getting shorted igbts from lightning and other random things. Probably need better dv/DT...
Hi all
I have a unique custom diy system. I have a diy inverter based around eg8010 micro running off 48v 240v,8kw. I have a 5kw grid feed inverter connected on 240v side to 6kw of panels. I also have a igbt switch between panels and grid feed inverter to turn off solar input when battery is...
