2nd grid tie inverter

[yankee99]

Hope for some assistance ?

 

I have a diy grid tie system 3kw. AC inverter output feeding a breaker in my pool room which then feeds a breaker in my main consuner box.

 

My question if i were to add a separate solar system add a breaker to my consumer box for the additional inverter ac output is this ok?

Yes, I have 3 of 6Kw grid-tied inverters.  It’s too many, but 6-9kw is fine.

Ok just curious if the pea grid goes down since both inveters are live how do they know to also shut down ?

They have anti-Islanding software built-in, I’m not sure exactly how they know, but they certainly do and they all shut down simultaneously.
