Frequently Asked Questions

The best switchboards for solar farms are modular, UL 891 certified switchboards. These are designed for flexibility, high reliability, and ease of maintenance, with options for main breaker or main lug output, and support for both direct and cable connections to MV transformers. EPEC’s switchboards are specifically engineered for solar, data center, and energy storage applications.

480VAC and 800VAC refer to the voltage levels at which electrical systems operate. 800VAC systems can handle higher power loads and reduce current (and thus cable size) for the same power, which can lower installation costs and improve efficiency. Both are supported by EPEC’s modular switchboards, which are designed to accommodate different voltage requirements for various applications.

A UL 891 switchboard is a type of low-voltage switchboard used for power distribution in commercial, industrial, and utility-scale applications. It is widely used in data centers, solar farms, energy storage, and EV charging infrastructure for its safety, reliability, and ability to handle high current loads.

Yes! Skidded solutions are pre-assembled, factory-tested units that streamline installation and reduce on-site labor. They’re ideal for fast-track projects, remote locations, or sites with limited space. EPEC’s skidded solutions ensure rapid deployment, consistent quality, and minimal disruption to your operations.
Yes, solar systems often require medium voltage (MV) transformers to step up or down voltage for efficient transmission and distribution. EPEC’s solutions include options for direct or cable connection to MV transformers, tailored for solar and EV applications.
The balance of system (BoS) includes all components necessary to support the main power-generating unit, such as wiring, inverters, switchboards, mounting systems, safety devices, and sometimes batteries and chargers. These components manage, convert, and distribute electricity safely and efficiently.
Yes, EPEC’s modular switchboards and skidded solutions are designed for easy upgrades and expansion, allowing you to add or replace components as your needs evolve.
Custom switchboards typically have a lead time of 16–24 weeks, depending on size and complexity, with options for expedited delivery in some cases.
Contact EPEC Solar Solutions’ support team for troubleshooting and maintenance needs. Our team provides ongoing support for all installed systems.
EPEC’s industrial solar equipment comes with comprehensive warranties, typically ranging from 1 to 5 years depending on the component.
Absolutely! Data centers are increasingly adopting solar infrastructure to achieve energy independence, reduce costs, and meet sustainability goals. EPEC’s solutions include advanced monitoring and backup systems to ensure data center reliability and uptime..
Solar energy is clean, renewable, and emits no greenhouse gases during operation. By switching to solar, you reduce air and water pollution, conserve natural resources, and contribute to global efforts to combat climate change. It’s a smart choice for businesses committed to sustainability.
