FranklinWH aPower battery certified to standard normally reserved for data centers

FranklinWH Energy Storage has received TIA-942 certification for its aPower battery storage system. The Telecommunications Infrastructure Standard for Data Centers from Telecommunications Industry Association (TIA) specifies the minimum requirements for data centers, including site location, architectural, electrical, mechanical, fire safety and security requirements.

TIA-942 ensures the reliability and availability of equipment. Extending the standard to home energy systems provides homeowners the confidence that they will have power when it is needed, FranklinWH claims. Adopting the data center standard offers consumers and partners a transparent, objective assurance that the energy storage system performs to the highest standard of reliability and robustness, with ultra-clean and stable UPS-grade power delivery.

“With this certification, we are raising the bar for residential energy storage, giving homeowners added confidence that their system will perform when they need it most,” said Gary Lam, CEO of FranklinWH. “TIA-942 is a rigorous, measurable standard trusted by the world’s most critical facilities. Bringing this level of proven reliability to the home means performance isn’t just promised, it’s verified.”

Developed by the TIA and accredited by ANSI, TIA-942 certification evaluates infrastructure across power systems, redundancy, monitoring, fault tolerance and overall resiliency. The standard is issued by Enterprise Products Integration (EPI) and defines four increasing levels of reliability, each requiring stringent engineering and system design to minimize downtime and ensure continuous operation. It is widely considered the leading standard for uptime in data centers and other always-on facilities and, until now, had never been applied to residential energy systems.

The standard defines four rated levels, with rated 4 representing the highest level of redundancy, fault tolerance, maintainability and resiliency. For decades, the standard has served as one of the most rigorous and complete reliability frameworks. FranklinWH’s aPower received TIA-942 certification across the full rating spectrum, from rated 1 through rated 4.
