The Risen 20.48kWh LiFePO4 Battery is a scalable energy-storage solution built from four 5.12kWh stackable battery modules. Each module has a 51.2V nominal voltage, 100Ah capacity and 5120Wh rated energy, giving the complete system approximately 20.48kWh nominal energy and 400Ah combined capacity. The batteries use LiFePO4 chemistry and feature an integrated BMS for battery management and protection. Communication ports include RS485, RS485A and RS485B, while SOC and ALM/RUN indicators make it easy to monitor battery status. Each battery module includes an ON/OFF switch, reset function, DIP switch and protected positive/negative terminals. The stackable configuration provides a neat and organized energy-storage solution for solar systems. Model SH5KFL.
