Three-phase AC panel without RCD - 20A

20A 400Vac Three-Phase Photovoltaic AC Panel for Single 8/9 kW Inverter Without Interface Protection

The 20A 400Vac three-phase photovoltaic AC panel for a single 8/9 kW inverter without interface protection is an electrical panel designed for the management, protection, and distribution of the alternating current (AC) side in small and medium-sized photovoltaic systems with a single three-phase inverter.

The electrical panel is configured to manage an 8/9 kW three-phase photovoltaic inverter and includes protection, isolation, and surge protection devices to ensure the safe operation of the system and the correct distribution of the AC electrical line.

This AC panel for photovoltaic systems is made of a wall-mounted ABS enclosure with an IP65 protection rating and is suitable for installation in outdoor environments, thanks to the presence of selected components, internal wiring, cable glands, and identification labels.

Function of the AC Panel in Photovoltaic Systems

The photovoltaic AC electrical panel represents the collection and protection point of the alternating current line between the inverter and the electrical system. Its main function is to ensure electrical safety, component protection, and system continuity.

The panel includes devices dedicated to protecting the electrical line, such as:

• miniature circuit breakers
• residual current circuit breaker
• surge protection device (SPD)
• fuse holder with protection fuses

The configuration protects the AC side of the system from overloads, residual current faults, and overvoltages caused by atmospheric conditions or switching operations, contributing to the overall safety of the photovoltaic system.

The compact design of the enclosure, along with the input/output terminals, ground bar, and cable glands, also facilitates connection and installation operations.

The panel is supplied with paper technical documentation, an electrical diagram, and visual instructions to ensure the correct connection of the components during installation.
