Custom MV/LV Substations & E-Houses
Integrated, factory-tested solutions compliant with CEI 0-16 standards for photovoltaics, industry, infrastructure, and facilities.
Key Strengths
Plug & Play
Pre-assembled and internally wired substations, ready for installation and immediate connection to the MV/LV grid, minimizing on-site commissioning time.
100% Factory Acceptance Testing (FAT)
Point-to-point inspection, insulation tests, and functional testing on circuit breakers, protection relays, and auxiliary circuits prior to shipment, complete with the release of the factory test report.
High Environmental Resistance
Shelters built with a painted aluminum framework and insulated sandwich panels, engineered for any installation environment.
CEI 0-16 Compliance
Engineering and design compliant with CEI 0-16 standards for photovoltaics, industrial applications, infrastructure, and utilities.
Remote Control & Monitoring
Real-time remote monitoring and management of substation parameters via our proprietary GC-Link interface device.
