7.3.3.2 (Optional) Three-Phase Imbalance Control (EMMA Networking)
Function Description
Three-phase imbalance control applies to the following scenarios:
● Asymmetric phase feeding with feed-in limitation: The feed-in power of each
phase in the three-phase power grid cannot exceed the preset threshold. The
inverter outputs dierent power for each phase based on the loads of each
phase to ensure that the feed-in power of each phase does not exceed the
preset threshold.
● PV+ESS asymmetric phase feeding for self-consumption: When the ESS
discharges power to the loads, the inverter outputs phase-specic power
based on the load of each phase and tracks the loads on each phase to
ensure that no ESS discharge power is fed to the grid while the PV power can
be fed to the grid.
The preceding two scenarios are supported concurrently.
