Configuration

Specifications

Single-phase 230V plug-in (Schuko) battery, 1.92 kWh per unit, expandable to ~7.7 kWh (up to 4 stacked battery modules per unit). Each STREAM AC unit has a fixed 800 W built-in microinverter; adding battery modules increases capacity but NOT the 800 W output ceiling, so outputScalesWithModules=false. Multiple STREAM AC units (up to 6) can be installed, each with its own 800 W inverter, so total household output scales at the system level (e.g. 2 units = 1600 W), but no single unit exceeds 800 W. The STREAM AC variant has no PV/solar MPPT input (solar requires the STREAM Microinverter, Ultra or Pro models); solarInputW=null. AC charge input 800 W. No native P1/smart-meter dongle; smart-metering done via EcoFlow Smart Meter, Shelly or Homey. No backup/UPS output. Round-trip efficiency not published by manufacturer (a Dutch review cited ~63% at low load, anecdotal, not used). Usable capacity percentage not published. Cycle life 6000 cycles to 70%, 10-year warranty.
