Custom Solar EBOS Solutions: Advantages for Performance, Cost, and Reliability

Success in large-scale solar projects comes down to balancing up-front costs with long-term performance. While Electrical Balance of System (EBOS) components typically account for less than 20% of total material costs, they play a critical role in ensuring reliable power production over the life of the plant. Getting Solar EBOS right not only improves long-term performance; it can also deliver meaningful short-term project efficiency.

EBOS includes every electrical component used to carry, manage, and consolidate power up to the inverter. It can be grouped into three main categories:

• Conductors (wires, cables, and connectors)
• Cable management systems that secure and protect conductors
• Enclosures such as disconnects and combiner boxes that consolidate power and enable safe operation

Each of these areas presents opportunities for optimization.

At first glance, factory-built disconnects and combiners often appear more cost-effective than custom solutions. However, up-front savings can erode over time. Here’s why many EPCs are turning to custom EBOS solutions instead.

Notes from the Field

ASG Power, based in Rocky Hill, Connecticut, has delivered design-engineered manufacture solutions for custom power distribution, automation, and cable assemblies for over 25 years. The company specializes in high-performance products built to meet NEC, UL, and IPC standards for safety and workmanship.

Today, solar and battery energy storage system (BESS) EBOS solutions represent a growing share of their business. Here’s why EPCs rely on custom providers like ASG Power for utility-scale and commercial & industrial projects.

Optimized for the project 
Even highly standardized utility-scale projects include variations. Custom providers can adapt to these differences, ensuring components install as intended and maximizing field labor efficiency.

Value engineering 
Design-build partners bring engineering expertise to tailor solutions for specific project requirements and environmental conditions. They can recommend where to invest in more durable solutions and where simplification can reduce costs without sacrificing performance.

Built for regional compliance 
Meeting regional codes and standards can introduce delays when using off-the-shelf products. Custom solutions help ensure compliance from the start, reducing risk during inspection and commissioning.

Shorter, more transparent supply chains 
Working with a trusted partner improves traceability and can support domestic content goals. Just as importantly, it enables more reliable delivery timelines, helping keep complex projects on schedule.

Built in Reliability

Effective wire management is foundational to reliable EBOS design. It protects conductors from abrasion, reduces strain on terminations, improves airflow, and enhances service access. Just as importantly, it ensures a clean, consistent build across assemblies, which simplifies installation, inspection, and maintenance.

ASG Power incorporates high-quality Panduit wire management solutions, including wire duct, adhesive mounts, and cable ties, to create more organized and reliable systems.

They also standardize copper compression lugs for large power cables. Copper provides excellent conductivity, minimizing resistance and heat buildup in high-current applications. When properly crimped, these lugs deliver secure, durable terminations that withstand vibration, heavy loads, and harsh operating conditions.

Together, these solutions enhance the safety, efficiency, and overall quality of ASG Power’s renewable energy systems.
