| SolaX Inverter Modbus | Works Local | Serial SZG and firmware TJ1 recognised as PV GEN2 X3Saved copySummary - Recognize Growatt inverters with serial prefix `SZG` and firmware prefix `TJ1` (e.g. serial `SZGDCL505K`, firmware `TJ1.0`). - Map both to `PV | GEN2 | X3` (3-phase PV, 2 MPPT), matching the local fix that cleared the `unrecognized Growatt inverter type` error. - Fixes #2261. ## Test plan - [ ] With an SZG / TJ1 Growatt on Modbus, confirm setup no longer logs unrecognized inverter type - [ ] Confirm 3-phase PV entities populate (grid L1/L2/L3, PV1/PV2 strings) - [ ] Review that classification as GEN2 remains appropriate if a named nameplate model is confirmed later Made with Cursor Excerpt saved from GitHub on 2026-10-23. | PR #2262 · 2026-08 |
