SD51-100 is a reliable energy storage solution developed for residential energy storage systems and commercial applications, featuring a compact design, high efficiency and long-lasting LiFePO4 (Lithium Iron Phosphate) technology. With its 51.2V nominal voltage, 100Ah capacity and 5.12 kWh energy storage capacity, it safely stores energy generated by solar power systems, provides uninterrupted power during outages and helps reduce energy costs.
The built-in LCD display makes it easy to monitor the battery’s operating status, state of charge, voltage and other key information. Its Bluetooth connectivity enables real-time monitoring and control via mobile devices. The intelligent BMS system protects both the user and the battery’s long-term operation through overcurrent, overvoltage, overcharge, over-discharge and short-circuit protection. A 100A continuous charge/discharge current and 200A peak current provide high performance and stable operation for everyday energy needs.
With a service life of up to 6,000 cycles, a natural cooling system and a robust metal enclosure, SD51-100 is an ideal solution for residential energy storage systems, solar energy applications, UPS and backup power systems, camper vans and mobile living vehicles, boats, off-grid systems, and small to medium-sized commercial businesses. Its compact construction, low maintenance requirements and high safety standards provide efficient, reliable and sustainable energy storage performance for many years.
