pv_inputs_per_mppt Review required
2 (product page implies 3 MPPTs / 5 strings, i.e. 2/2/1) — existing ANMA record
3 (value returned for the 'No. of PV strings per MPPT' row under all three model columns) — datasheet V3 targeted read
probable row mis-alignment in the PDF text extraction (the '3' is almost certainly the 'No. of MPPTs' row). The Isc split 40/40/20 and the manual's 'PV3, PV4 -> MPPT2, PV5 -> MPPT3' both support a 2/2/1 string layout. Not resolved - existing value left untouched.
max_battery_charge_power_kw Review required
UNKNOWN (previously noted as 'Max power 43000 VA', column attribution unclear) — existing ANMA record
20000 W / 20000 VA — datasheet V3 (AU), SH20T column
the 43000 VA figure does not belong to the SH20T battery row; a targeted re-read of the SH20T column gives 20000 W / 20000 VA.
physical.weight_kg Review required
40 — datasheet V3 (AU), SH20T column, targeted three-column read
38 — user manual Ver17 p.9 technical table as returned by a full-page extraction
the manual table covers SH5T-SH25T; 38 kg is the SH15T value in the datasheet, so the manual extraction most likely picked the neighbouring column. 40 kg is the better-sourced SH20T value.
