Inverter / Transformer Skids

Designed, engineered, and manufactured “offsite” in Clayton, NC, prebuilt scalable systems are shipped in purpose-built packages i.e. skid mounted, ISO containers, power modules, enclosures, power houses,  E-buildings recognized for rugged reliability and value. Typical mechanical equipment and electrical distribution may include integrated switchboards, PLCs, panels, transformers, inverters, energy storage, motor control centers, HVAC, medium voltage. 

Offsite Fabrication of Skids for Solar

Why PCX?

PCX is a leader in the offsite manufacturing of electrical and  mechanical systems for Commercial Construction, Industrial/Utility and Modular Data Center markets. PCX was one of the early concept originators of offsite prefabricated electrical solutions. The primary strength of the company has always been the ability to engineer, integrate and fabricate complex electrical and mechanical systems into large custom enclosures or skid based systems. All projects are engineered and built in compliance with the NEC (National Electric Code) and UL Classifications, which results in a more rapid approval by the local AHJ (Authority Having Jurisdiction).

Beginning with their initial discussions with you, and throughout new projects and/or facility expansions, they employ a creative approach to supporting your needs. PCX collaboratively aligns with you as a strategic partner, providing modular solutions that will enable your organization to mitigate risk and reduce overall costs through accelerated construction schedules.


All PCX systems are designed and built in their manufacturing facility located in Clayton, North Carolina approximately 20 minutes outside of Raleigh, North Carolina. All systems are U. L. classified and built to exacting quality standards driven by the customers’ specifications under the guidelines of ISO 9001:2015

The Advantages of Offsite Fabrication

Offsite fabrication is a process which involves the design and manufacture of complex assemblies and/or modules where the fabrication occurs at a remote location normally away from the work site.

The typical benefits of offsite fabrication are reduced construction cycles, improved space utilization, and lower costs due to reduced change orders. To capture the full benefits of offsite fabrication, a project strategy must be employed that will change the orientation of the project process from the construction to the manufacture and installation.

Benefits of Offsite Manufacturing

  • Reduced construction cycle time

  • Standard and consistent quality

  • Predictive costs and predictive schedule

  • Avoidance of weather delays

  • Factory commissioning reduces punch list items

  • Less skilled labor required at work site

  • Reduced safety risk at site

  • Reduction of material waste at site

  • Early permanent power

  • Reduced overall construction costs

Prefabrication Saves Time and Money

Case Study 6.25MW Project

  • 2 week acceleration of 6.25 MW Project

  • Reduction of field personnel, travel costs and reduced QC etc..  $100K per year

  • Reduction in transaction costs associated with EC Management?

  • Engineering savings?

  • Elimination of Site Waste?

  • Accurate Consistent Quality

  • Available UL Certification

  • Improved Site Safety (Insurance Premiums)

  • More projects per year with same team
