ABB launches high-efficiency power conversion Proteus PV and BESS portfolio
- June 17, 2026
ABB has launched its Proteus PV and battery energy storage systems (BESS) portfolio.
With utility-scale renewable electricity generation expected to grow by 60 per cent over the next four years, according to the International Energy Agency1, the Proteus portfolio delivers high-efficiency power conversion solutions for utilities, power producers, and renewable developers worldwide, a release by ABB said.
ABB will present its new Proteus solar inverter at Intersolar 2026 (June 22–25, Munich, Germany) at stand B3.250.
PV is widely 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.
Proteus: Solar
ABB’s enhanced Proteus portfolio can meet this demand. Inverters, stations and control systems deliver industry-leading efficiency up to 99.45 per cent, maximizing energy yield. Ultra-clean power output with THDi below 0.7 percent, reducing equipment stress and extend 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 optimized airflow management and enhanced build quality, delivering greater long-term reliability and performance across a wide range of operating environments.
Proteus: BESS
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.
Over 120 GW of power conversion
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, the ABB release added.
