As grid constraints tighten and renewable deployment accelerates worldwide, global engineering giant ABB has unveiled its new Proteus portfolio of photovoltaic (PV) and battery energy storage system (BESS) solutions.

 

The new portfolio is aimed at supporting the next wave of large-scale clean energy buildout.

 

The launch comes as utility-scale renewable electricity generation is projected to rise by 60 percent over the next four years, according to the International Energy Agency. ABB’s Proteus line is positioned as a high-efficiency power conversion platform designed for utilities, independent power producers, and renewable developers operating in increasingly complex grid environments.

 

“The global energy transition requires proven, scalable and reliable power conversion solutions,” said Daniel Gerber, Business Line Manager, Renewable Power at ABB. 

 

“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, delivers high performance and consistent project execution worldwide.”

 

Solar PV continues to dominate as the most scalable and cost-competitive clean energy source, powering rapid deployment across major markets including China, India, and the United States. That growth is driving stronger demand for efficient grid integration and stable, high-performance conversion systems.

 

ABB says the Proteus portfolio is engineered to meet that demand with inverter and station efficiencies reaching up to 99.45 percent, alongside ultra-low harmonic distortion below 0.7 percent—aimed at reducing equipment stress and extending system lifetime.

 

The platform also integrates hybrid liquid and air cooling for durability, while a compact design reduces installation complexity and logistics costs. The new inverter architecture emphasizes optimized airflow and enhanced build quality to support long-term operation across diverse environments.

 

On the storage side, rising renewable intermittency is accelerating demand for BESS capable of stabilizing grids and balancing supply and demand. 

 

ABB’s Proteus BESS offering includes bi-directional converter stations and advanced control systems with grid-forming and black-start capabilities. Its battery-agnostic design and low harmonic distortion target large-scale utility deployments requiring flexibility and resilience.

 

ABB highlighted its global footprint—more than 120 GW of installed power conversion capacity across 70+ countries—backed by engineering and service support for utilities, EPCs, and developers. Designed for a 30-year service life, the Proteus portfolio is supported by lifecycle services aimed at maximizing reliability and operational uptime.
