A 100kW photovoltaic system was installed in Sabaudia (Latina), connected to the LV grid, consisting of two 50kW inverters. Field switchboards were constructed, including DC surge arresters and emergency release coils.
The interface switchboard was constructed with a dedicated SPI control unit, including relay box testing and CEI 0-21 certification, including the interface device (DDI) and backup device (DDR).
