| subcategory | stacked all-in-one residential ESS - hybrid (PV + battery) inverter plus stackable battery modules |
| variant_note | Four published system variants share one enclosure set and differ in AC output power and coupling: 8.0HS (8000 VA, hybrid), 10.0HS (9999 VA, hybrid), 8.0AS (8000 VA, AC-coupled), 10.0AS (9999 VA, AC-coupled). This record is 'Cygni 8.0HS'. The AU user manual title additionally shows an '-M2/M3/M4' suffix that appears to encode the number of stacked battery modules; that document was located but not fetched. |
