Interface Switchboard CEI0-21 MICRO from 15 to 33kW
MICRO interface panels have been engineered to take up as little space as possible while ensuring all the essential interface protection functions for photovoltaic systems. They are available in three sizes: 15kW, 20kW, and 33kW, all housed in a single insulating container with an IP67 rating. All panels are equipped with a differential circuit breaker for inverter protection, an emergency UPS, a NA003 interface relay, an AC-3 contactor, and voltage and system-connected indicator lights.

Interface switchboard CEI0-21 OPEN from 20 to 66kW
The OPEN series interface panels represent the latest evolution of LV connection panels for CEI 0-21 photovoltaic systems. The OPEN formula allows you to choose the panel size based on the system's power without needing to know the final inverter configuration in advance, which can be completed later on site. The panels are designed with space and wiring pre-arranged for the inverter protection switches, which simply need to be attached and connected using the connection bridges already supplied (see table). This is a significant advantage for industry operators, as the same panel is suitable for numerous system configurations and can therefore be managed more flexibly in stock. The OPEN panels are all equipped with indicators to indicate the presence of the grid and the connected system. They are also available in the OPEN-T version with a bench-mounted relay box test.
