About the Felicity Solar FLA24250WG2 25.6V 6.4kWh LiFePO4 Battery

The Felicity Solar FLA24250WG2 is a LiFePO4 storage module holding 6.4kWh of nominal energy on a 25.6V nominal bus, rated for 175A of continuous charge and discharge, which is 4,480W, with a 300A peak for 15 seconds. The unit weighs 49.5 kg, measures 400 × 402 × 275 mm, and carries a 5 Years warranty. Depth of discharge is rated at ≥95%, so at least that share of the 6.4kWh nominal energy is available on each cycle, and cycle life is rated at ≥6,000 cycles. The operating window runs 22.4-28.8V around the 25.6V nominal bus. Up to 15 units run in parallel for a maximum of 96kWh, and the enclosure is wall-mounted or floor-mounted with an IP21 protection degree for indoor siting. Packed for transport the FLA24250WG2 weighs 54.5 kg in a 512 × 472 × 333 mm carton, so the 49.5 kg figure is the module itself, not the shipment. We are an authorised Felicity Solar distributor and supply the FLA24250WG2 from our own stock.
