max_short_circuit_current_per_mppt_a Review required
200 (combined/unspecified) — EU datasheet 2023-12-18 (the record's original source)
UNRESOLVED — EU user manual 2026-02-24, p.54 - this session's extraction of the short-circuit row returned an implausible value ('100000 W'), i.e. the row could not be read reliably; the figure was NOT changed
extraction/row-alignment failure on the 2026 manual, not a documented disagreement
