100 kW Three-Phase Photovoltaic AC Panel with CEI 0-21 Interface Device for 50 kW + 50 kW Inverters
The 100 kW three-phase photovoltaic AC panel with a CEI 0-21 compliant interface device is an electrical panel designed for the management, protection, and control of the alternating current (AC) side of photovoltaic systems connected to the low-voltage electrical grid.
The electrical panel is configured to manage two 50 kW three-phase photovoltaic inverters, for a total system power of 100 kW. It integrates electrical protection, isolation, control, and monitoring 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 enables the safe connection of inverters to the electrical grid, ensuring compliance with the technical requirements set out by the CEI 0-21 standard for connecting 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 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 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 by 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 inverters, distribution lines, and the grid, reducing the risk of faults and improving the stability of the power generation system.
The integration of the GSM communicator also enables remote monitoring of the photovoltaic system and integration with energy monitoring and management systems.
