My idea id to add an already purchased set of 3 x multiplus 5000-48 V and another Fronius 27 kW PV inverter. Battery capacity will not be modified as it was already oversized. I thought of the following scheme :

Can anyone confirm or amend this extension project?

I dont believe you can stack different inverters, more quattro 10k's would be fine. Your also exceeding the post inverter KVA input limit with 54kva of Fronius behind 45kva of inverters. Seems like you need 3 more 10kva quattro's added to the stack..
