Up to 38 kV class, 60 Hz; designed to IEEE C37.121/ANSI C57.12.34; UL/CSA certifiable. Entogo designs and builds the Modular Skid-Mounted Unit Substation (Step-Up / Collector) in its own factory with a vertically integrated supply chain: this product ships in 16–24 weeks (new UL or CSA certification can extend that, within a guaranteed 36-week worst case), and every Entogo product carries a minimum 36-month manufacturer warranty. This **modular skid-mounted unit substation** is a fully prefabricated, fast-deploy package for renewable collector and step-up (boosting) duty. Because the all-metal cabins are factory-built, wired and tested, it cuts site footprint by roughly 30% and design, installation and commissioning time by roughly 70% versus a conventional field-built substation. It is configured as a step-up collector for solar PV, wind and battery storage, or as a step-down service-entrance substation, up to **38 kV class** equipment (34.5 kV system) at 60 Hz. Intelligent environmental control suits high-heat, high-humidity and dusty sites, with cold-climate, wind and seismic packages specified per location. Cloud-platform remote health diagnostics, fault analysis and SCADA integration enable unmanned operation and full-lifecycle equipment management. Designed and built to **IEEE C37.121**, **ANSI C57.12.34** and IEC 62271-202, with UL (cULus) / CSA certification available on request. ## Key features - Fully modular, skid-mounted unit substation that cuts site footprint by ~30% and design/installation/commissioning time by ~70%. - Configured as a step-up collector (solar, wind, BESS) or a step-down service-entrance substation; up to 38 kV class equipment, 60 Hz. - Designed and built to IEEE C37.121 (unit substations), ANSI C57.12.34 and IEC 62271-202 — UL (cULus) / CSA certification available on request. - All-metal prefabricated cabins with intelligent environmental control for harsh climates; cold-climate, wind and seismic packages per site. - Cloud-platform remote health diagnostics, fault analysis and SCADA integration for unmanned operation and full-lifecycle management.

It is configured as a step-up collector substation for solar, wind and battery-storage interconnection, or as a step-down service-entrance substation for industrial loads — up to 38 kV class equipment (34.5 kV system), 60 Hz. - **What makes the modular skid format faster to deploy?**: Because the cabins are factory-built, wired and tested, the modular skid cuts site footprint by roughly 30% and design/installation/commissioning time by roughly 70% versus a conventional field-built substation. - **Which standards and certifications apply?**: Designed to IEEE C37.121, ANSI C57.12.34 and IEC 62271-202, 60 Hz, with SCADA-ready remote diagnostics. UL (cULus) / CSA certification is available on request.
