Hi,
I am planing for an AC coupled ESS configuration with grid-tied PV inverters. I have 2 design goals, the ESS storage shall be charged by PV excess power only and the stored energy shall flow into the private loads only (i.e. the ESS Multi shall produce a bit less than private load consumption).
Problem comes into play with the standard ESS configuration, in particular placement of the ESS meter. I made a sketch to describe the problem and an alternative solution approach.
As I have seen from the ESS design guide, the CCGX appears to have only input for one ESS meter, which would not support the alternative solution approach.
Any clue, good idea or advice to make it happen?
