I need Your help/advice.
We have client with single phase electric installation.
He has two Fronius inverters. Each inverter has connected 3.6kWp of photovoltaics.
We want to build him ESS on BYD and Multi Plus-II 5kVA.
1st Fronius will be connected to the input of the Multi (when there is no grid – inverter turns off).
2nd Fronius will be coupled on the output of the Multi (when there is no grid – inverter still works).
Client cannot feed Energy back to the grid.
Can we realise zero-feed-in function in configuration mentioned in above (scheme in the attatchment)?
If not can You give me any suggestions?
