Solar Skid Substation
A high-performance, factory-integrated power block engineered for utility-scale solar generation. UTEC's Solar Skid Substation transforms complex solar-plant interfaces into one streamlined, project-ready solution, addressing harmonic-rich currents and voltages, transient over voltages, significant load variation, reactive power requirements, and reverse power flow. It brings medium-voltage switching, an inverter-duty transformer, low-voltage distribution, protection, control, communications, auxiliary systems, and internal interconnections together on a common skid.
Key Product Features
One Integrated Solar Power Block
Medium-voltage switching, inverter duty transformer, 400 V to 800 V LV MDB, protection, control, communications, auxiliaries, and internal connections are engineered as one coordinated package for a cleaner project interface.
Solar-Duty Transformer Engineering
The transformer is rated up to 8 MVA at 33/0.8 kV or 13.8/0.8 kV and uses an enhanced insulation system with withstand capability against harmonics generated by solar inverters.
RMU Choice for Every Digitalization Strategy
The skid can be equipped with Enerswit+ Conventional, SMARTEC, or SMARTEC Special Use RMUs, allowing the MV architecture to be aligned with the project's operational, automation, monitoring, and application requirements.
Advanced Protection and Plant Communication
Coordinated protection and control across the RMU, transformer, and MDB supports a connected power block with communication capability to the plant DCS or SCADA system.
Flexible 400 V to 800 V LV Architecture
While 800 V is the common voltage for modern utility-scale solar inverter applications, the LV MDB can be engineered from 400 V up to 800 V to match the inverter topology, feeder arrangement, protection philosophy, metering requirements, and approved project design.
Flexible Skid and Enclosure Engineering
The mechanical arrangement, enclosure concept, ventilation, access, and environmental protection can be optimized to suit the project specification and site conditions.
Factory-Integrated for Faster Deployment
A common skid, coordinated interfaces, and pre-engineered internal connections minimize site integration complexity and support consistent installation quality.

Designed for Solar Electrical Stress
Transformer design measures address harmonics, transient overvoltages, load variation, reactive loading, and reverse power flow.
DCS / SCADA Connectivity
Integrated protection and control can communicate with the plant supervisory and control platform.
Three RMU Platforms
Available with Enerswit+ Conventional, SMARTEC, or SMARTEC Special Use RMU platforms to match the required operational and automation philosophy.
Solar Skid Substation: Integrated, Adaptable, Solar-Ready
For utility-scale PV plants and renewable-energy developments, UTEC's Solar Skid Substation delivers more than equipment integration. It provides a coordinated, solar-ready power block combining specialized inverter-duty transformer engineering, flexible 400 V to 800 V LV distribution, a choice of three Enerswit+ RMU platforms, project-specific protection and control, and factory-integrated construction. The result is a powerful foundation for faster deployment, optimized interfaces, and dependable renewable-energy performance.
