About the Felicity Solar FLB48279TG1-AU 51.2V 13.98kWh LiFePO4 Battery

The Felicity Solar FLB48279TG1-AU is a floor-mounted LiFePO4 battery of 13.98 kWh at 51.2 V nominal, symmetrical in power: 7680 W and 150 A on charge, the same 7680 W and 150 A on discharge, with a 300 A peak held for 15 seconds and depth of discharge rated at 95%. Up to 32 units run in parallel. This model's record carries no cycle-life figure, so none is quoted here. Communication is unusually wide — CAN2.0 and RS485 to the inverter, plus WiFi and Bluetooth — with an LED for status at the cabinet, and protection is layered as BMS, Fuse, Breaker and MX+OF. The operating window is 44.8 V to 57.6 V, charging from 0 °C to 55 °C and discharging from -20 °C to 55 °C. Two weights and two sizes are published and they are not the same measurement: the product is 115 kg net at 895×450×235 mm, and the shipment is 124.5 kg gross at 1013×588×342 mm. The warranty is 5 Years. We are an authorised Felicity Solar distributor and supply the FLB48279TG1-AU from our own stock.
