I have 1000W grid tie inverter and I connect it to battery terminal, to combine electricity from grid and from my EV.
Input: 12V DC
Output : 220V 60hz (Korea)

It works well. However it doesn't work if electricity from grid is out. In that case you should use...
Thank you for support Ray, but it seems only LDC is working and others are not.
I attached screenshot.
