Wiring Diagram
The diagram illustrates the connection of multiple solar modules to the APsystems QT2D microinverter. The output from the microinverter is then connected to a three-phase grid. The diagram shows a typical setup where several modules are connected in series to one microinverter, and the AC output from multiple microinverters is consolidated for grid connection.

Notes
- (1) Customer can adjust via ECU according to grid requirements.
- (2) Can be adjusted according to local grid regulations.
- (3) In installations with poor ventilation, the inverter may enter a derating mode.
- (4) To ensure communication quality, it is recommended that a single ECU register no more than 80 microinverters.
