SOFAR SF-5KWH-L1 5.12kWh 51.2V Lithium Battery

The SOFAR SF-5KWH-L1 is a 5.12 kWh, 51.2 V low-voltage lithium iron phosphate (LiFePO4) battery for home energy storage. It works with 48 V hybrid inverters such as the SOFAR HYD-3~8K-LS1-PRO, HYD-10/12K-LS1 and HYD-5-20K-LT1. You can start with one and add more as your needs grow, up to 16 batteries in parallel (about 82 kWh). It mounts on the wall, stacks on the floor or fits a standard 19-inch cabinet.

Key features

Long-lasting LFP cells: safe lithium iron phosphate chemistry, 4.6 kWh usable energy per battery
Smart BMS: monitors cell voltage, current and temperature, balances the cells to extend cycle life, and protects against over-charge, over-discharge, over-current and high/low temperature
Easy expansion: up to 16 batteries in parallel, with automatic ID coding (just press the master battery's start button)
Flexible installation: wall mounted, bracket stacking or in a 19-inch cabinet
Clear status: 5-LED state-of-charge display plus run and alarm lights
Works with your inverter: CAN and RS485 communication, compatible with SOFAR hybrid inverters
Certified: UN38.3, IEC 62619, IEC 62040-1, SAA
