AC-coupled battery, no direct DC/PV MPPT input on the unit (solar comes via a paired microinverter), so solarInputW is null. Single unit inverter delivers 1200 W continuous from its own battery; output steps up to a 2300 W system ceiling via bypass/auto-boost only when chained with a second STREAM AC Pro or a STREAM Ultra, hence outputScalesWithModules true. The 800 W figure is the regulatory feed-in/socket cap on a shared circuit, not the hardware ceiling. Round-trip efficiency >=95% (AC-AC) per spec. Cycle life 6000 cycles to 70% capacity. Home Assistant supported via EcoFlow cloud API community integrations (Stream devices); no official local/Modbus interface documented (modbus null). P1/smart meter: works with EcoFlow Smart Meter and third-party meters (Shelly 3EM etc.). Weight reported 22.8 kg on EcoFlow.nl; some retailers list 21.5 kg.
