max_ac_power_kw Review required
13.2 — datasheet 2026-04-24, 'Max. AC Output Apparent Power 13200VA'
19.2 — this session's extraction of the manual 2026-03-19 p.49, 'Max AC Apparent Power 19,200VA' (12K column)
almost certainly a row/column misalignment in the manual extraction (19200 W matches the max PV input power of the neighbouring SG02LP1 family, and 13200 VA = 1.1 x 12 kW is the consistent Deye value); the datasheet figure is stored
