Huawei’s 506 kW Smart String Inverter wins Smarter E AWARD at Intersolar Europe 2026
Huawei’s new flagship product – the SUN2000-506KTL is the first 500 kW+ string inverter commercialised in the industry. It’s not just the simple upgrade in power and voltage on the previous generation of SUN2000-330KTL. The SUN2000-506KTL delivers three pioneering breakthroughs: industry’s first 1000 Vac PV string inverter, industry’s first grid-forming string inverter and with industry’s highest power density. It provides customers with four core benefits – optimised investment returns, enhanced grid-forming capabilities, efficient O&M and superior safety and reliability, and elevating the innovation of smart string inverter to a new level.
As the flagship product of Huawei’s next-generation utility-scale Smart PV solution FusionSolar9.0, the 506KTL string inverter is already in large-scale deployment. Since 2025, Huawei has rolled the solution out across diverse scenarios in the Chinese market, and international adoption is accelerating rapidly. More than 10 GW of projects globally are currently under construction using FusionSolar9.0, as developers across multiple markets have re-evaluated their designs in favor of the solution’s lower BOS and superior lifecycle economics.
Huawei is committed to supporting the energy transition with solutions that are technically leading, commercially robust, and built for the long term. By enabling solar plants to become intelligent, grid-supporting assets — not passive generation sources — to drive the high-quality development of the industry.
The smarter E AWARD is a great recognition of Huawei’s dedication in innovation. Huawei stated at the award ceremony that it was a great motivation for the team, and was far more than an honor, adding it is a powerful affirmation of Huawei’s persistent innovation pursuits, relentless technological exploration, and customer-centric philosophy.
Guided by the brand concept “Making the Most of Every Ray”, Huawei is committed to unlocking the full potential of solar energy by bringing more reliable, high-value and innovative solutions.
Huawei will always uphold open collaboration, working hand-in-hand with global partners to offer high-quality product and solutions continuously, and create a greener and better future together.
