20 kWp Interface electrical panel (2 inverters)

Electrical interface box 20 kWp (2 inverters)

Overview

SecSun 20 kWp interface cabinet.

The 20 kWp interface electrical panel for three-phase systems is ideal for managing and protecting larger photovoltaic systems. It includes 63A main disconnectors, an interface relay compliant with CEI-021 standard, and three-phase surge protectors that ensure maximum safety. With a 40A 4P contactor, this electrical panel is robust and reliable, ideal for outdoor environments thanks to its IP65 protection rating. Its configuration makes it a reliable connection point between the inverter and the electrical grid, guaranteeing compliance with current regulations. The panel is available in single or double inverter models, and with or without a test report.
