Two Certifications in Hand, Advancing into North America: WidenEdge Earns SGS North America and California High-Standard Grid-Connection Certificates

As the new-energy transformation accelerates into deeper waters, the global energy-storage market is embracing unprecedented growth opportunities. Recently, WidenEdge's flagship product—the MGC grid-forming inverter—was officially awarded the North America and California high-standard grid-connection certificates issued by the internationally authoritative certification body SGS. This milestone achievement marks the full opening of a new era for WidenEdge energy storage. With the spirited attitude of "Exploring a New Carbon Frontier, Setting Off Now," the company is embarking on a new North American journey alongside its global partners.

Securing the "Two Keys" to North American Grid Connection—Hardcore Technology That Passes the Highest Standards

It is well known that the North American market has some of the world's most stringent grid-access standards and technical specifications. Drawing on outstanding foundational technology, the WidenEdge MGC grid-forming inverter has secured two heavyweight certifications, truly achieving "worry-free grid connection" and "a direct route into California."

The First Key

UL 1741 SB certification—ensuring worry-free grid connection. The UL 1741 SB certification that the WidenEdge MGC grid-forming inverter has passed is a rigorous standard built on the IEEE 1547-2018 and 1547.1-2020 specifications. Under this standard's demanding tests, WidenEdge's products demonstrated excellent grid adaptability, with their outstanding voltage ride-through and frequency ride-through capabilities fully verified. In addition, the product fully supports grid-support functions such as Volt-VAR and Volt-Watt, providing a solid technical backbone for stable grid operation.

The Second Key

California CSIP V2.1 conformance certification—a direct route into the California market. As a benchmark for new-energy market access in North America and worldwide, California places highly challenging demands on smart inverters. WidenEdge's product not only met the complex requirements for smart inverters under CPUC Rule 21, but also passed all five BASIC control tests, successfully obtaining California CSIP V2.1 conformance certification. This marks WidenEdge's hardcore qualification to land smoothly in California, a highland of energy storage.

A Grid-Forming Core and Wide Voltage Compatibility—Showcasing Ultimate Product Strength

Behind these technological breakthroughs lies WidenEdge's continuous cultivation and innovation in the underlying architecture of the inverter. The newly certified MGC grid-forming inverter is the crowning achievement of WidenEdge's R&D strength.

A SiC silicon-carbide grid-forming inverter that delivers powerful performance. Built around an advanced SiC silicon-carbide grid-forming inverter as its core technology, this product series substantially improves overall equipment performance. In terms of specifications, the product supports 480 Vac three-phase output and offers three power ratings—120 kW, 150 kW, and 180 kW—for flexible customer selection. More importantly, in weak-grid environments and off-grid scenarios, the WidenEdge MGC grid-forming inverter can establish a stable grid, safeguarding system continuity and reliability.

A single unit compatible with mainstream North American voltage levels. To address North America's complex grid conditions, WidenEdge built exceptional compatibility into the product from the very start of its design. A single unit can adapt to the mainstream North American voltage levels of 208 V, 240 V, and 480 V. This broad voltage compatibility greatly expands the product's range of applications.

From Certified Products to Customer Value—Fully Empowering the Commercial Success of Projects

For WidenEdge, obtaining certification is not the end goal but the starting point for converting technical advantages into commercial value for customers. Guided consistently by the core principle of "from certified products to customer value," this compliance certification delivers a leap in core value for North American customers across three dimensions.

A clearer compliance path

 The dual certification of UL 1741 SB and California CSIP V2.1 fully covers grid-connection, grid-support, and smart-communication specifications. This makes WidenEdge's products the most direct "passport" for equipment selection and grid-connection compliance in North American projects, making the path to compliance clearer than ever before.

More robust project delivery. 

With a complete set of core certifications, WidenEdge inverters can substantially reduce repeated testing and design rework during project delivery. This advantage strongly mitigates the potential risk of grid-connection delays, helping customers bring projects online faster and seize an early edge in generation revenue.

More reliable grid coordination

Rigorously verified voltage/frequency ride-through, together with grid-support functions such as Volt-VAR and Volt-Watt, enables the PCS to form a stable grid in complex scenarios including weak grids, microgrids, and off-grid systems. This exceptional reliability of grid coordination genuinely safeguards the long-term safe operation of the system.

This is an important step in WidenEdge's globalization strategy. The company continues to live out its brand philosophy of "Powering From the Edge," dedicated to bringing the industry more reliable and innovative products.

This November, WidenEdge will make a major appearance at the RE+ exhibition in Las Vegas with its newly certified MGC grid-forming inverter. We sincerely invite peers and partners from the global new-energy industry to visit and exchange ideas. See you in Las Vegas this November!
