Technical file: Pi LV1
The Pytes Pi LV1 is a modular low-voltage LiFePO₄ energy storage system combining the BMU battery modules with the BCU main control unit. Together, they form a scalable, safe and high-performance solution for residential and commercial solar systems, backup power, and off-grid applications.
The system is designed for fast installation, simple expansion, and stable daily operation. One BCU controls and manages stacked BMU modules, providing intelligent monitoring, communication with inverters, and complete system protection.
