Huawei SUN2000 MAP0 Series - Optional) Three-Phase Imbalance Control; Optional) Three-Phase Imbalance Control (Smart Dongle Networking)

Parameter Description
Energy
Measureme
nt Mode
Balanced
Measurement
Default setting. The forward energy and reversing energy
are respectively calculated by integrating the sum of power
from three phases.
Unbalanced
Measurement
The forward energy and reversing energy are respectively
calculated by integrating the power of each phase.
7.3.3 (Optional) Three-Phase Imbalance Control
7.3.3.1 (Optional) Three-Phase Imbalance Control (Smart Dongle
Networking)
Function
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 dierent 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-specic power
based on the load of each phase and tracks the loads on each phase to
ensure that no ESS energy is fed to the grid while the PV power can be fed to
the grid.
The preceding two scenarios are supported concurrently.
