## About this series

Series Spring \| Rack-Mounted Battery (LV) are low-voltage LFP modules in a rack format, designed for clear expansion and easy service within a 19-inch cabinet. The applied chemistry, **LiFePO4 (LFP)**, offers higher thermal stability and resistance to overloads compared to typical NMC, translating in practice to increased safety for home and business use, as well as better parameter repeatability during frequent charging and discharging. Each module features an **advanced BMS** monitoring key operating conditions, along with solutions facilitating startup and diagnostics. For the user, the key advantage is that the series offers **a high number of cycles** and a long warranty-meaning a significantly lower cost of energy storage throughout its entire lifespan, without rapid capacity loss. The system is **scalable**-additional modules can be added in parallel as demand increases. Thanks to communication (e.g., CAN/RS485), the storage systems integrate well with hybrid inverters and off-grid installations, proving effective in homes, small businesses, and as a reliable backup power source.
