Electrical interface box 70 kWp (1 inverter)

Overview

SecSun 70 kWp interface cabinet.

The 70 kWp Electrical Interface Boards with 1 and 2 Inverters are designed for large-capacity photovoltaic systems. Both models offer robust protection through disconnectors, contactors and surge arresters to ensure system safety and efficiency. The main difference between the two models is in the management of the inverters: the model with one inverter offers a more compact solution, while the model with two inverters allows greater operational and energy management flexibility.

Both models are available with the test report.

These switchboards are ideal for applications requiring accurate and safe control of the energy generated by large-scale photovoltaic systems.
