Hi
I'm looking at setting up a DC-coupled ESS system with RS 450s. It will be 3 phase: 10kVA per phase with 3 x Quattro 48/10000.
All loads will be on the AC Out. However, there is a 40kVA supply and I wonder what happens if at some moment, some 35kVAs are drawn from the system- and if there is sufficient battery capacity, will the inverters provide their maximum (30kVAs) and the remaining 5kVAs come from the grid with no problem? Similarly, if more than 10kVA is pulled from one of the phases- will the remaining load be powered seamlessly from the grid on that phase?
(I'm only talking about in ESS mode, obviously if there is a black-out, I understand that in back-up mode, the power will be limited by the maximum inverter power)
Thanks
