Streamline Your Solar Project with EPEC’s 480-800VAC up to 4.2MVA “Rack on Rails” Power Skids

As the demand for clean, reliable, and scalable solar energy grows, so does the need for advanced electrical infrastructure that can keep pace with evolving project requirements. At EPEC Solar Solutions, we’re proud to introduce our 480-800VAC up to 4.2MVA Rack on Rails power block Skids—a robust, all-in-one solution engineered to streamline installation, maximize efficiency, and ensure the highest standards of safety and reliability for commercial and utility-scale solar projects.

What Are EPEC’s 480-800VAC up to 4.2MVA “Rack on Rails”?

These power block skids are fully integrated, factory-engineered units designed to serve as the backbone of your solar installation’s Balance of System (BoS). Each Rack on Rails unit combines key electrical components—including a medium voltage transformer, switchboard, inverters, auxiliary power, and SCADA systems—into a single, ready-to-install package. This modular approach eliminates the complexity of sourcing and assembling multiple components, AC side cabling, and instrumentation installation, saving both time and labor costs while reducing the risk of installation errors.

Key Features and Benefits

High Power Density: Each skid delivers up to 4.2MVA, making it ideal for large-scale solar farms and commercial installations that require robust, scalable power management.
Flexible Voltage Range: Operating at 480–800VAC, these skids are compatible with all major inverter brands and sizes (125/150/250/275/350kW) available in the U.S., ensuring adaptability for a wide range of project specifications.
Streamlined Installation: Factory integration means each skid arrives on-site pre-wired, pre-tested, and ready to connect—dramatically reducing on-site construction time and complexity.
Enhanced Reliability: Incorporation of electronic trip Molded Case Circuit Breakers (MCCBs) on all feeders eliminates nuisance tripping, ensuring uninterrupted power delivery and minimizing downtime.
Safety and Compliance: Built to meet stringent UL 891 & NEC standards, these skids utilize high-quality enclosures, surge protection devices, and advanced monitoring for maximum operational safety.
Optimized Performance: With advanced SCADA integration, operators gain real-time visibility and control over power distribution, enabling predictive maintenance and proactive management of system health.
Made in the USA: Designed and manufactured domestically, EPEC’s Rack on Rails power block skids guarantee quality, support, and rapid response for U.S.-based projects.
