When the new UL3141 certification for power control systems appeared in late 2024, we didn’t see it as just another compliance challenge. We saw an opportunity to innovate, and to lead.

One of our customers urgently needed megawatts of new power, and the only path forward, working with the utility, was to certify our controller to this brand-new standard that was still in draft form. We connected with one of the engineers who helped write UL3141 to fully understand not just what it required, but why it existed and how it was meant to protect the grid. Those insights guided every design decision as we developed the hardware and software to meet an aggressive timeline.

A few months later, we delivered a first-to-market controller certified to UL3141, proving that our technology could meet the highest safety and interoperability standards while helping our customer bring new power online.

Our philosophy is simple: turn standards into strategy. By understanding the intent behind each requirement, we can design smarter and move faster. During the final stage of certification, a last-minute change was requested to how we detected a fault condition. Our team quickly updated the code, shipped it to the Fremont test site, and passed. This agility is what sets Critical Loop apart.

Now we’re building on that success with new certifications like IEEE 2030.5, expanding our controller’s ability to manage batteries, inverters, and generators. This controller is more than hardware, it’s the brain of a flexible interconnection system that can manage industrial-scale loads and integrate seamlessly with existing infrastructure.

As demand for intelligent, grid-ready systems grows, we see compliance not as a barrier but as a catalyst for progress. UL3141 didn’t just set a new standard, it gave us the chance to set the pace.
