You are talking about AC Coupled. Rosie supported this now and does need to be enabled. When the grid fails and the Rosie is charging the battery from the Sunny Boy it will frequency shift to control the Sunny Boy. This is a typical addition to a grid tie system to provide backup

Hi:
And thanks for the information FNG.

You have confirmed to me that they work, the AC couplings, look good to me.

2-second question.

My solar installer license is going to install and he says it has to be UL listed, because the grid provider wants a copy UL certificate. Rosie is going to the grid.
My SMA needs Rosie.

Thanks FMG.
