ABB has re-entered the power electronics market with the launch of its new Proteus portfolio, offering advanced power conversion solutions for the solar photovoltaic (PV) and battery energy storage system (BESS) sectors.
The new product range follows ABB’s acquisition of Gamesa Electric and includes high-efficiency 4.7 MVA central solar inverters with up to 99.45% conversion efficiency, alongside bidirectional converter stations and advanced control systems for energy storage applications.
ABB said the Proteus portfolio is designed to support grid stability, renewable energy integration, and large-scale clean energy deployment.
The company plans to officially showcase the new solar inverter range at Intersolar Europe 2026 in Munich.
The launch marks ABB’s return to the power electronics business after exiting the sector in 2020, reflecting growing global demand for solar and energy storage technologies as the clean energy transition accelerates.
