AC-coupled w/ Fronius switching between phases

Hi everyone,

I have 3 grid systems and I use one with Quattro to power the house. All single-phase.

What would be an elegant way to connect another Fronius to ACOUT and increase the PV during cloudy days?

So Fronius#2 connected to L2, disconnects and connects to ACOUT of Victron. If I use something like a programmable relay, would that damage the system?
