Three-phase 50A 400Vac photovoltaic AC panel with CEI 0-21 interface protection system for a single 25 kW inverter
The three-phase 50A 400Vac photovoltaic AC panel with an interface protection system designed in accordance with the CEI 0-21 standard is an electrical panel designed for the management, protection, and control of the alternating current (AC) side in photovoltaic systems with a single 25 kW three-phase inverter connected to the low-voltage electrical grid.
The electrical panel is configured for the connection and protection of a 25 kW photovoltaic inverter. It incorporates electrical protection devices, isolation, surge protection, and an interface device, with a configuration designed to ensure operational safety, continuity of operation, and compliance with the technical requirements for connecting power generation systems.
This AC panel for photovoltaic systems allows the safe connection of the inverter to the electrical grid, ensuring the management of the AC side with dedicated protections and a CEI 0-21 SPI interface system designed with buffered power supply exceeding 5 seconds.
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, component protection, and operational reliability.
The interface protection system constantly monitors electrical grid parameters such as:
- grid voltage
- frequency
- line operating conditions
- correct status of the connection interface
In the presence of anomalies or conditions that do not comply with the limits set by the standard, the system intervenes by operating the interface device to disconnect the system from the grid and protect the inverter and other installed electrical components.
In photovoltaic systems, the AC panel also allows the coordination of protections between the inverter, electrical line, and distribution grid, contributing to the safety of the system and the correct management of energy production.
