Hi,
Il would like to explain my idea to connect in parallel two inverters and their battery.
The two systems are the same: inverter SUN2000 (SUN2000-6KTL-L1 monophase) and a battery LUNA2000 10 kWh. But they are connected to two different AC phases, so i cannot use the AC coupling.
My idea is to connect these two inverters using the DC bus / battery bus, which is after the MPPT block, as you can see in the image, so a DC coupling.
My scope is to create a macro-system where the two inverters are normally indipendent with their PV array, but if there is a surplus of energy from one side (not necessary stored in the battery but only by PV, in this phase of the project) can be used by the other inverter and the energy will be transported by the dc bus.
Obviously, I need to protect the connection of the dc buses by overpower with fuses, because for example the batteries can give up to 5 kW.
Have anyone test this electrical connection? In your opinion, Will this connection work or not?
Thank you so much
Happy holidays
