I am interested in configuring a combined AC coupled and DC coupled power generation system for my home that would be connected to the public grid. Last month the Underwriters Laboratory (UL) in the United States found that the MultiPlus-II 48/3000/35-50 120V meets UL 1741 standards for inverters, converters, controllers and interconnection system equipment). It appears that this specific model of Multiplus inverter can now be used in grid connected systems in the US with the approval of the local power company/co-op.Below is a schematic for what I have in mind. The building I am configuring for is 120/240 volt, single-phase, three-wire service. The configuration I am proposing may be familar to many Multiplus users outside of the United States. I would appreciate a constructive critique of this diagram. It appears that the Fronius grid inverter only has one AC out. I'd like to have two hot legs from this system. Thanks in advance.
UPDATE 4/28/2023 Updated schematic to show grid connect per ejrossouw comment.
