PixiiBox 48/3300
Multi-function two port power conversion unit
All-in-one box
The PixiiBox is a multi-functional power conversion unit for energy storage systems. It operates as a single-phase, bidirectional grid-tied inverter, an MPPT converter for PV panels, and a rectifier or inverter. This flexibility allows seamless integration into diverse system designs.
Save costs through battery services like peak shaving, PV self-consumption, power boost and backup power.
The BESS that pays for itself by generating revenue from various electricity markets to maximize ROI.
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.
Modular, scalable and flexible
The modular design enables scalability to meet any power requirements, with hot-swappable modules ensuring unmatched serviceability and reliability. The PixiiBox can autonomously support the grid or be remotely controlled through the Pixii Gateway. Its compact, efficient, and versatile design makes it an ideal solution for energy savings and grid stability. Can be used as single and 3-phase configurations.
