Electrical Balance of System (EBOS): The Bridge Between Generation and Delivery

The bridge between power generation and interconnection is evolving fast. Solar, hydrogen fuel cells, battery storage, advanced turbines and next-generation systems are reshaping the grid—and changing the equipment that supports it.

But power only creates value when it is connected safely, controlled reliably and delivered efficiently to the utility or the load.

That is the role of Electrical Balance of System (EBOS), and it is where ASG Power adds value.

We provide power solutions up to 2,000 VDC and 1,000 VAC, helping energy and industrial teams bridge the gap from generation to interconnection, commissioning and long-term operation.

Quick Answer: What is EBOS?

EBOS (Electrical Balance of System) is the electrical infrastructure that connects generation assets to the grid or a facility load. It includes equipment like disconnects, switchboards, combiners and integrated controls that help energy flow safely, efficiently and in compliance with applicable requirements.

EBOS Is Where Projects Win or Lose

Projects often focus heavily on the generation source, losing sight of what’s required to connect the source for its intended utility or application.

• Equipment interfaces do not align
• Field wiring expands beyond plan
• Commissioning gets delayed by compliance gaps
• Procurement gets stuck managing multiple vendors

ASG Power reduces that risk by partnering early, building integrated systems that arrive ready to install and built to last.

What ASG Delivers for EBOS Power Distribution

We support utility-scale and C&I energy projects with EBOS equipment that helps streamline installation and maintain long-term reliability, including:

• Load break disconnects
• Combiners
• Recombiners
• Switchboards
• Mini power centers
• E-House (electrical house) packages
• Prewired and assembled skids

Solutions That Ensure Safety, Uptime and Scalability

EBOS is not only distribution hardware. Controls determine how safely and consistently the system runs, how quickly issues are diagnosed and how easily a platform scales.

ASG Power designs and manufactures UL 508A control panels and custom control cabinets, with UL 698A options and both open and enclosed versions. Open panel formats work well for retrofit applications where enclosure constraints apply.

This is where ASG Power’s experience building industrial control panels translates directly to EBOS and energy projects: tighter integration, clearer documentation and build consistency that supports faster commissioning.

Where that helps project teams:

• EPCs: fewer coordination gaps and smoother commissioning handoffs
• OEMs and integrators: repeatable builds that support performance targets and delivery schedules
• Engineering firms: clearer interfaces, cleaner integration and fewer late-stage changes
• Roles supported: procurement, supply chain, electrical engineering, preconstruction, product development

UL 891 Switchboards for Reliable, Safe Power Distribution 

When your EBOS scope requires robust distribution, ASG Power can manufacture UL 891 switchboards up to 600 V and 2,500 A, configured to your application and integration needs, including standalone builds or integration skids and e-houses.

We manage quality across design, sourcing, assembly and testing to deliver dependable switchboards built to your specifications.

Modular EBOS Delivery: E-Houses and Skids That Reduce Field Deployment Time  

Fieldwork is where schedules slip. Modular builds help teams shift complexity into controlled, repeatable manufacturing. They are easy to install and reduce field deployment time, helping you meet your timelines.

ASG’s E-House and skidded solutions integrate power distribution, controls and communication into compact, mobile units that are designed, built and tested in the USA.

Benefits teams can plan around:

• Faster deployment with streamlined, in-house manufacturing
• Reduced onsite labor and fewer install-time surprises
• Modular systems that scale with operational needs

Why ASG for EBOS 

ASG Power’s EBOS approach is built around the outcomes decision makers care about most: safety, schedule, cost control and long-term performance.

What you gain with ASG:

• Power up fast: prewired skids reduce install time and onsite labor
• Responsive delivery support: faster lead times than larger electrical OEMs for many custom builds
• More direct collaboration as requirements evolve
• Quality and compliance you can trust: built in-house to standards including UL508A, UL698A and UL98B
• Control costs: value-engineered to minimize risk and reduce rework
• Customization: flexible manufacturing enables tailored customer solutions
• Traceability and QA: systems assembled in Rocky Hill, Connecticut, with documented inspection and testing
• Assembled in the USA: modular builds designed to reduce field risk and support faster deployment

Key Takeaways  

• EBOS is the bridge between generation and delivery, where safety and uptime are won or lost
• ASG supports EBOS solutions up to 2,000 VDC and 1,000 VAC
• Integrated distribution, controls, skids and e-houses reduce onsite labor and schedule risk
• UL-certified manufacturing and quality systems ensures quality you can trust

FAQ 

Q:           What does EBOS stand for in power systems?

A:            EBOS stands for Electrical Balance of System. It includes the electrical equipment that                                         connects generation assets to the grid or a facility load.

Q:           What equipment is included in EBOS power distribution?

A:            Common EBOS equipment includes disconnects, combiners, recombiners, switchboards,                             mini power centers, e-houses and pre-wired skids, depending on the system architecture.

Q:           How do control panels support EBOS performance?

A:            Control panels coordinate monitoring, switching, safety logic and operational control. ASG                             designs and manufactures UL 508A control panels and offers cUL and UL 698A-certified                                   options to support compliance and reliable operation.

Q:           What is the advantage of skidded EBOS and e-houses?

A:            Skids and e-houses reduce field wiring and onsite labor by delivering modular, integrated                                 assemblies that are designed, built and tested before arriving on site.
