Product Information:

    The PV grid-connected cabinet is a key device that connects the photovoltaic (PV) power generation system to the public grid. It undertakes multiple tasks including DC power collection, inverter grid connection, safety protection, and operation monitoring.

Workflow:

    1.DC Power Input
     The DC power output from the PV array enters the cabinet through the DC input terminal of the PV grid-connected cabinet.

    2.Conversion of DC Power to AC Power
     The inverter, either integrated inside or externally connected to the cabinet, converts the DC power into AC power synchronized with the grid frequency and phase.

    3.Injection of AC Power into the Power System
     Through the AC output terminal, the inverter injects the generated AC power into the public grid or the user-side power system in a safe and controllable manner, establishing a power transmission channel between the PV        system and the power system.

    4.Operation Status Monitoring and Management
     Real-time monitoring of parameters such as voltage, frequency, and power at the grid connection point is performed. Active protection measures are taken against abnormal data to ensure the safe and stable operation of        the PV power generation system.
