The landscape of power distribution is changing. Whether in utility-scale solar generation or mission-critical data centers, the demand is no longer just for more power—it is for efficient, scalable, and higher-voltage power.
As industries strive for greater efficiency, standard 600V infrastructure is often reaching its limit. At EPEC Solutions, we are seeing a decisive shift toward 800VAC systems and modular Data Center Electrical Infrastructure. Here is why the industry is evolving and how your equipment needs to keep up.
For years, 600VAC was the standard for commercial and industrial solar. However, as inverter technology advances, developers are moving toward higher voltages to minimize cable losses and reduce overall Balance of System (BoS) costs.
This transition requires a new breed of equipment. Standard off-the-shelf gear often stops at 600V, leaving a gap in the market for robust 800VAC Switchboard solutions.
Integrating an 800VAC Solar Inverter requires more than just a rating change. The entire downstream protection system must be rated to handle the increased potential safely.
At EPEC, we specialize in manufacturing UL 891 Switchboards that are fully rated for these demanding high-voltage solar applications, ensuring you pass inspection and energize on schedule.
Not every project is a new build. A massive wave of “Solar Repowering” is currently underway as early-generation PV plants reach the end of their inverter lifecycles.
Many of these older sites operate on legacy voltages, such as 600VAC swbd or the less common 630VAC switchboard configurations. Replacing an inverter often means the existing switchgear is no longer compatible or code-compliant.
Our Solar repower swbd solutions are custom-engineered to fit existing footprints while upgrading the protection to modern standards. We provide Repower swbd units that integrate seamlessly with modern inverters, saving you the massive cost of trenching new cable.
While solar chases higher voltage, the data center sector chases density and intelligence. Data Center Electrical Infrastructure must be robust enough to ensure 99.999% uptime but flexible enough to handle rapid server upgrades.
We provide Data Center Power Systems designed for density. From the main UL 891 Deadfront Switchboard down to the rack level, every connection point matters.
We know you have options. Giants like Eaton and Schneider Electric offer standard catalogs. But when you have a complex Repower Switchboard (600VAC / 630VAC) project or a tight deadline for a custom 800VAC MCCB integration, “standard” often means “delayed.”
EPEC Solutions fills the gap where rigid product lines fail. We combine the manufacturing rigor of a major OEM with the agility of a local partner. We don’t just sell you a part number; we engineer a solution that fits your specific site conditions.
Whether you are designing a next-gen 800VAC solar plant or upgrading a critical data center, you need equipment built for the task.

Developers are moving to 800VAC to minimize cable losses and reduce overall Balance of System (BoS) costs. As inverter technology advances, standard 600V infrastructure is often reaching its limit regarding efficiency.
Standard off-the-shelf gear is often insufficient; you need specialized Molded Case Circuit Breakers (MCCBs) tested specifically for 800VAC operation. EPEC manufactures UL 891 Switchboards fully rated for these higher voltage applications to ensure safety and code compliance.
We provide custom-engineered switchboards designed to fit existing footprints while upgrading protection to modern standards. This allows you to integrate modern inverters without the massive cost of trenching new cable.
Our systems use modular Power Distribution Units (PDUs) that allow you to swap and upgrade modules without tearing down the entire rack setup. They also feature intelligent monitoring to track load balancing and prevent downtime.
