Fully integrated, pre-wired and factory configured system that reduces the installation time significantly.
The BESS that pays for itself by earning from electricity markets and saving cost through peak shaving and power boost.
Built for future-proof performance
Designed and manufactured in Europe. Combining robust engineering with high-quality components to deliver modular, scalable and reliable energy storage for critical applications and demanding environments.
Secure, connected, and compliant
Our 48V systems are built for always-on operation. Encrypted communications, secure remote access, and full GDPR compliance, enabling uninterrupted connectivity, real-time insight, and maximum ROI through value stacking.
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.
Scalable high-capacity PowerBase
Supports up to 540 kW and 1.8 MWh. Designed for scalable energy storage with high-density battery modules. Ideal for long-duration use and large-scale site configurations.
1. The stated power and energy capacities are baseline, or nominal, values. Actual performance can vary and may be constrained by several factors, including the state of charge (SoC), state of health (SoH) of the system, as well as thermal conditions. 2. A 3-phase connection requires at least three PixiiBoxes, one for each phase.
