Single 1.92 kWh fixed unit, not module-expandable, so output does not scale with capacity. On-grid AC output is 800 VA nominal/max but datasheet footnote [1] states it is customizable via the S-Miles Home App up to 2000 VA (the 800 W is the default socket cap; 2000 VA is the hardware ceiling). Off-grid/backup port: 800 VA continuous, 1200 VA peak for 10 s. Max charge/discharge 1000 VA. Bidirectional DC/AC efficiency up to 96.5%; round-trip up to 87%. AC-coupled (plug into Schuko socket or microinverter), no PV MPPT input. Backup/EPS supported via firmware. P1 smart meter accessory enables AI-EMS. Home Assistant via MQTT (S-Miles Home App) and community integrations, not native. No documented Modbus support. Usable capacity percentage not stated on datasheet.
