Compact and scalable – all in one system

From grid-connected BESS supporting FCAS, arbitrage, and balancing support to off-grid BESS and SAPS. Smarter microgrid control, remote diagnostics, and future-proof flexibility with a high-density, liquid-cooled battery cabinet for outdoor energy storage.

Built for future-proof performance

Engineered and designed in Europe. Combining robust engineering with high-quality components to deliver modular, scalable and reliable energy storage for critical applications and demanding environments.

Resilient by design, reliable in use

Pixii BESS feature built-in redundancy, active monitoring, and automated recovery protocols. This ensures secure operation even under failure or cyber threat, ideal for mission-critical energy storage needs.

Comprehensive Service Level Agreement (SLA) and support

Proactive maintenance, fast response, and certified installers help maximize uptime and extend lifespan. SLAs secure optimal performance and ROI throughout the system lifetime.

Delivers 261kWh of nominal energy in a compact, IP55-rated outdoor cabinet for demanding environments

Scalable and modular by design – expand capacity effortlessly from 261kWh to multi-MWh systems

All-in-one

Combines battery storage, power conversion and intelligent energy management in one compact outdoor system, built on Pixii’s proven modular platform.

Safe and intelligent

Liquid cooling, fire suppression, smoke detection and IP55 ensure safe operation. Pixii EMS optimises energy distribution, load management and battery performance.

Flexible and scalable 

Scales to multi-megawatt systems for peak shaving, renewables, EV charging, backup and microgrids. Front access and standard interfaces simplify maintenance and integration.
