ABB Launches Proteus PV and BESS Portfolio

18 Jun 2026 CW Team

The company will present its new Proteus solar inverter at Intersolar 2026, scheduled from 22 to 25 June in Munich, Germany.

Daniel Gerber, Business Line Manager, Renewable Power, ABB, said the global energy transition requires proven, scalable and reliable power conversion solutions. He added that ABB, with over 120 GW of installed power conversion capacity, combines PV, BESS and control systems technologies with its global engineering, manufacturing and service capabilities.

According to ABB, solar PV continues to play an important role in supporting net-zero goals, industrial electrification and the wider energy transition. The growth of utility-scale solar projects in markets such as China, India and the USA is increasing demand for reliable, high-efficiency power conversion and grid integration systems.

ABB said the Proteus portfolio includes inverters, stations and control systems offering efficiency of up to 99.45 per cent. The solutions also deliver ultra-clean power output with THDi below 0.7 per cent, helping reduce equipment stress and extend system life.

The portfolio features advanced hybrid liquid and air cooling for long-term operational reliability. Its compact system architecture is designed to reduce installation complexity, transport costs and on-site assembly requirements. The new Proteus inverter also includes optimised airflow management and enhanced build quality to support reliability across different operating environments.

For energy storage applications, ABB’s Proteus BESS solutions include bi-directional converter stations and advanced control systems. The solutions offer features such as grid-forming and black-start operation, along with a battery-agnostic design and ultra-low harmonic distortion for utility-scale BESS projects.

ABB said it operates in more than 70 countries and supports utilities, EPCs and developers across major regions. The Proteus portfolio has been designed for a 30-year service life and is supported by lifecycle services for long-term reliability and operational availability.

MEMU Suspension Disrupts Commuters Between Vadodara And Dahod

The Vadodara–Dahod Mainline Electric Multiple Unit (MEMU) service has been temporarily suspended for 26 days after its rake was diverted to Odisha to manage the surge in passenger traffic during the annual Rath Yatra in Puri. Indian Railways redeployed several MEMU rakes from different zones to meet the additional travel demand for the festival scheduled from the seventh of July to the second of August. As a result, train numbers 69233 and 69234 operating between Vadodara and Dahod will remain cancelled for the duration. Railway authorities advised passengers to use alternative train service..
