Function of the AC Panel in Photovoltaic Systems

The photovoltaic AC electrical panel represents the interface between the photovoltaic inverter and the electrical grid. Its main function is to manage the alternating current side of the system, ensuring electrical safety, operational continuity, and component protection.

The integrated interface device constantly monitors electrical grid parameters such as:

• grid voltage
• frequency
• electrical line operating conditions
• distribution grid stability

In the event of anomalies or conditions that do not comply with the limits set out in the CEI 0-21 standard, the system automatically intervenes by disconnecting the photovoltaic system from the grid to prevent damage to the components and ensure the safety of the electrical system.

In commercial and industrial photovoltaic systems, the AC panel also enables the coordination of electrical protections between the inverter, distribution lines, and the grid, reducing the risk of failures and improving the stability of the power generation system.

The integration of the GSM communicator also enables remote supervision of the photovoltaic system and integration with energy monitoring and management systems.
