Dvcc and Ac-coupled fronius + dc coupled mppt

Hi,


In an offgrid system where their is both an Ac coupled fronius and a dc coupled mppt, is the Ac coupled fronius treated as the “grid” and priority given to the mppt reg?

Then for instance if the load increases past the maximum charge current of the batteries is the fronius released, so to speak, from it’s frequency detrating to cover the load?

I am NO expert here

However I would suspect that it will all depend on how you set the multis/Quattros charger voltage settings and the DC Mppts voltage settings,


hope that makes sense
