13 kW Three-Phase Photovoltaic AC Panel with SPI and CEI 0-21 Interface Device for 2 x 6.5 kW Inverters
The 13 kW three-phase photovoltaic AC panel with an interface protection system (SPI) and a CEI 0-21 compliant interface device is an electrical panel designed for the management, protection, and control of the alternating current (AC) side in residential and commercial photovoltaic systems connected to the low-voltage distribution grid.
The electrical panel is configured to manage two 6.5 kW three-phase photovoltaic inverters, for a total system power of 13 kW. It integrates electrical protection, isolation, and control systems designed to ensure the coordination of protections between the inverters, distribution lines, and the electrical grid in accordance with Italian technical regulations for the connection of power generation systems.
This AC panel for photovoltaic systems allows the safe connection of the inverters to the electrical grid, ensuring compliance with the technical requirements set out by the CEI 0-21 regulations for the connection of power generation systems to the low-voltage distribution grid.
Function of the AC Panel in Photovoltaic Systems
The photovoltaic AC electrical panel represents the interface point between the photovoltaic inverters 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 interface protection system (SPI) constantly monitors electrical grid parameters such as:
- grid voltage
- frequency
- phase imbalances
- line operating conditions
In the event of anomalies or conditions that do not comply with the limits set by the regulations, 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 residential and commercial photovoltaic systems, the AC panel also allows the coordination of electrical protections between the inverters, distribution lines, and the grid, reducing the risk of faults and improving the stability of the power generation system.
