3 phase ESS and ac coupled solar on one phase

Hello community.

I have an idea to build an ESS system with 3 MP2's 48V 3000VA in a 3phase setup and an existing Solaredge SE3000H connected to one of the MP's at the AC out1 connection.

The idea is that the MP to which the SE3000H is connected, would be used to charge the battery while solar power is available and not charge when only grid is available. The charging function of the 2 other MP's would be disabled. The battery (10kW) would supply DC to all MP's.

In my opinion this would work but i'm not 100% certain. Any ideas - feedback on this?
