About the Felicity Solar FLH48100UG1 51.2V 5.12kWh LiFePO4 Battery

The Felicity Solar FLH48100UG1 is a rack-mounted LiFePO4 module of 5.12 kWh, 100 Ah and 51.2 V nominal; four to twelve modules build a 20.48 kWh to 61.44 kWh system at a nominal 204.8 V to 614.4 V. Two different figures: 5.12 kWh is one module, 61.44 kWh a full rack of twelve. Cycle life is rated at >6000; depth of discharge is a separate rating at ≥95%. System operating voltage spans 192-691.2 V, with a 192-576 V cut-off band and a 230.4-691.2 V charging maximum; one module works from 48 V to 57.6 V. Current is 100 A continuous, 120 A on a 15-second peak and 50 A recommended. Every module carries a smart BMS and breaker, a touch LCD, an LED, CAN and RS485. One module is 482.6×565×131 mm at 41.3 kg, the control module 482.6×565×150 mm at 10.3 kg, the package 562×687×250 mm at 45 kg. The IP21 enclosure charges 0 °C to 55 °C and discharges -20 °C to 55 °C, at 5-95% humidity, below 2000 m. Certified to UN38.3, CE-EMC, CB, EN IEC 62040-1 and IEC 62619; warranty 5 Years. We are an authorised Felicity Solar distributor and supply the FLH48100UG1 from our own stock.
