At a bustling booth in Munich this June, ABB will unveil a breakthrough in solar power technology that converts sunlight into grid-ready electricity with up to 99.45% efficiency — a figure that redefines what’s possible in clean energy infrastructure. As the world races to deploy renewable energy at scale, the Swiss-Swedish tech leader is answering the call with its enhanced Proteus portfolio, a suite of power conversion systems engineered to maximize energy yield and strengthen grid stability across utility-scale solar and battery storage projects.
With global renewable electricity generation expected to grow by 60% over the next four years, according to the International Energy Agency, the demand for reliable, high-performance conversion technology has never been greater. ABB’s new Proteus inverters and battery energy storage systems (BESS) are built to meet that surge, delivering not only record-breaking efficiency but also ultra-clean power output with total harmonic distortion below 0.7%, reducing wear on equipment and extending system lifespan. Advanced hybrid liquid and air cooling, combined with a compact, modular design, slashes installation time and transport costs — critical advantages in remote or logistically complex project sites.
The Proteus BESS solutions go a step further, integrating bi-directional converter stations and intelligent control systems that enable black-start capability and grid-forming functions — essential tools for restoring power after outages and stabilizing grids increasingly fed by variable solar and wind sources. Designed to be battery-agnostic, the system can integrate with any battery chemistry, offering developers long-term flexibility. These systems are not just efficient; they’re built to last, with a 30-year service life and lifecycle support that consistently outperforms industry benchmarks in reliability and availability.
ABB brings decades of global experience to the table, having already installed over 120 gigawatts of power conversion capacity across more than 70 countries. From the sun-drenched deserts of India to vast solar farms in the American Southwest and China’s renewable megaprojects, ABB’s engineering and local service networks ensure seamless project execution. The company’s presence at Intersolar 2026 in Munich — where the new Proteus inverter will make its debut — marks a pivotal moment in the evolution of grid-scale renewable integration.
As the energy transition accelerates, the infrastructure beneath it must be just as resilient and forward-thinking. ABB’s Proteus portfolio isn’t just keeping pace — it’s setting the standard for what clean energy systems can achieve, proving that high efficiency, long-term reliability, and grid resilience can go hand in hand.
