Absolutely. I am on the same page. But my 1kw setup is just for me to study real word vs. my math. I was not going to install on my roof. Ground mounting 4 panels is not going to raise any problems, and if it did, it is no problem for me to disconnect them.
The takeaway is that this is suppose to be a prelude to a whole house system.
I already have a generator transfer that was permitted years ago (Florida, hurricanes, generator, as it were). It however does the whole house. For this little test I will need to pull my one circuit off the main panel, install separate isolated panel that is fed directly from my inverter. Now doing that may not be permittable and I will have to cheat it. I am not the type that likes to do such a thing but, 'say la vie'.
