ABB Launches Proteus PV and BESS Portfolio to Support Utility-Scale Renewable Energy Expansion

As grid constraints and renewables expansion accelerate, ABB has launched its Proteus PV and Battery Energy Storage Systems (BESS) portfolio. With utility-scale renewable electricity generation expected to grow by 60 percent over the next four years, according to the International Energy Agency, the Proteus portfolio delivers high-efficiency power conversion solutions for utilities, power producers and renewable developers worldwide.

ABB will present its new Proteus solar inverter at Intersolar 2026, June 22–25, Munich, Germany at stand B3.250.

Daniel Gerber, Business Line Manager, Renewable Power at ABB, said, “The global energy transition requires proven, scalable and reliable power conversion solutions. With over 120 GW of power conversion capacity installed to date, ABB combines its enhanced portfolio of PV, BESS and control systems technologies, global presence, engineering, manufacturing and service capabilities, delivering high performance and consistent project execution worldwide.”

 PV is acknowledged as the most scalable and cost-competitive clean energy source that is serving an essential role in achieving global net-zero targets, supporting further industrial electrification and advancing the energy transition. The rapid growth of utility-scale solar projects in major markets such as China, India and the USA is driving the demand from developers and producers for reliable, high-efficiency power conversion and grid integration solutions.

ABB’s enhanced Proteus portfolio can meet this demand. Inverters, stations and control systems deliver industry-leading efficiency up to 99.45 percent, maximising energy yield. Ultra-clean power output with THDi below 0.7 percent, reducing equipment stress and extending system lifetime.

Additionally, advanced hybrid liquid and air cooling supports long-term operational reliability, while compact system architecture lowers installation complexity, transport costs and on-site assembly requirements. The new Proteus inverter features optimised airflow management and enhanced build quality, delivering greater long-term reliability and performance across a wide range of operating environments.

Variable renewable energy sources are increasing grid variability and driving unprecedented demand for BESS solutions that bridge generation and consumption while ensuring grid stability, reliability and continuous power supply. ABB’s Proteus BESS solutions include bi-directional converter stations and advanced control systems. Advanced features, such as grid-forming and black-start operation, combined with its battery-agnostic design and ultra-low harmonic distortion, make it the optimal inverter for utility-scale BESS projects.

ABB has installed over 120 GW of power conversion capacity to date and operates in more than 70 countries, supporting utilities, EPCs and developers across every major region. With decades of expertise in power conversion and grid integration, ABB delivers proven solutions backed by local engineering and service capabilities that ensure technical support and reliable project execution. Designed for a 30-year service life, the portfolio is supported by comprehensive lifecycle services that consistently outperform industry benchmarks in reliability and operational availability.
