About the Felicity Solar FLA12280-EU 12.8V 3.6kWh Battery
The Felicity Solar FLA12280-EU is a 12.8V LiFePO4 battery holding 3.6kWh of nominal energy, rated for a continuous 1,875W of charge or discharge and 2,500W for 15 seconds, with a depth of discharge of ≥95% and a cycle life of ≥6,000 cycles. Charging is capped at 14.4V and 150A, and the operating window runs 11.2-14.4V. Peak charge or discharge current reaches 200A for 15 seconds. Sixteen FLA12280-EU units wire in parallel for 57.6kWh, so the bank grows with the load instead of being replaced. Note that the ≥95% depth of discharge, not the 3.6kWh nominal figure on its own, is what governs how much energy you can actually draw. Each unit weighs 26kg net and measures 379×241×286mm, in an enclosure rated IP21. We are an authorised Felicity Solar distributor, and the FLA12280-EU is covered by a 5 Years warranty.
