ABB has unveiled its Proteus PV and battery energy storage system (BESS) portfolio, comprising high-efficiency power conversion solutions. The portfolio has been introduced to address the growing demand for reliable power conversion and grid integration solutions driven by the rapid expansion of utility-scale solar projects.
The enhanced Proteus portfolio includes inverters, stations and control systems with efficiency of up to 99.45 per cent, helping maximise energy yield. The systems deliver ultra-clean power output with THDi below 0.7 per cent, reducing equipment stress and extending system lifetime. The portfolio also incorporates advanced hybrid liquid and air cooling to improve long-term operational reliability, while its compact architecture reduces installation complexity, transport costs and on-site assembly requirements.
The new Proteus inverter features optimised airflow management and enhanced build quality for improved long-term reliability across a wide range of operating environments. Meanwhile, the Proteus BESS portfolio includes bidirectional converter stations and advanced control systems, with features such as grid-forming and black-start capability. Its battery-agnostic design and ultra-low harmonic distortion make it suitable for utility-scale battery energy storage projects.
