How to read this page

Confirmed by this dataset

  • The verdict is derived from bound canonical entities, not fuzzy matching.

Not assumed

  • Missing pinout, firmware, cable or DIP data does not mean none is required.
  • A source-listed setup value is not automatically treated as a manufacturer-recommended method.

Exact-pair interpretation

Why GW29.9K-ET + BYD HVM 13.8 is listed this way

Compatibility basis

This published page binds the exact inverter GW29.9K-ET to the exact battery model BYD HVM 13.8. The current database resolution is CONDITIONAL under ET (15-30kW). The verdict is produced from the stored manufacturer-source relationship for these canonical entities, not from fuzzy search similarity or a generic voltage-class assumption.

Communication setup recorded for this Pair

No communication setup is added to this page unless it exists in the stored source evidence.

Evidence coverage

The result is backed by 1 page-level evidence record on page 3 of GW_BATTERY_COMPAT_20260901_EN_V029.1 (2026-09-01).

No extra wiring, DIP-switch, firmware, cable, charge-limit, or pinout claim is created from absence or analogy.

The source attaches 2 explicit conditions to this Pair; the condition text is shown separately and is not generalized to other models.
