Fully integrated, pre-wired and factory configured system that reduces the installation time significantly.
EMS for remote monitoring, configuration and control, eliminates the need for complex on-site configuration.
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.
Easy deployment
The system is designed for easy deployment, shipped with batteries installed, and can operate autonomously or be integrated with higher-level energy management systems.
