Base unit 1.92 kWh LFP, expandable to 11.52 kWh with up to 6 batteries; AC inverter output is fixed at 1200 W and does not scale with added battery modules (capacity scales, not power). Grid feed-in is software-capped to 600 W or 800 W depending on SKU (EF-EA-HD-M2K-600 / -800); the 1200 W figure is the hardware AC outlet/inverter ceiling. Max charging 1050 W, max discharging 1200 W. 2x MPPT at 500 W each = 1000 W PV. Backup via AC outlet bypass (10 A); Dutch retailer cites 2300 W total when combining 1200 W battery output with grid bypass, but bypass is pass-through, not battery inverter capacity. Round-trip efficiency not published on datasheet (forums cite ~85-88%, unverified, left null). Usable depth-of-discharge percentage not published. Home Assistant via community integrations (hassio-ecoflow-cloud), not official. Modbus support not documented.
