03 Product Introduction
Self Consumption System (AC-Coupled Scenario)
• Before enabling the power limit function, ensure that the AC-Coupled inverter or hybrid
inverter supports power limit.
• Enable the power limit function if GoodWe AC-Coupled inverter or grid-tied PV inverter is
applied in the PV system. Complete the power limit settings as required if a grid-tied PV
inverter from other manufacturers is applied.
• When power limit function is enabled, the PV system will purchase 100W power from the
utility grid.
