Validated compatibility

This page documents a real-hardware compatibility path, not a model-name assumption. TSUN Local still identifies devices from the local protocol exposed by the inverter/logger combination.

✅ Community validationA TSUN Local user reported that the integration works on a real TSOL-MS800 and supplied an anonymized Home Assistant diagnostic.
☀️ Two MPPT inputsThe independently documented test unit is a two-MPPT TSOL-MS800 and exposes the expected PV1/PV2 telemetry path.
🧩 Tested hardware pathObserved serial prefix Y47E… with logger firmware LSW5BLE_17_02B0_1.08-D1.
📡 Connection resilienceThe tester reported weak Wi-Fi and periodic disconnects, while noting that AC energy values remain retained during connection loss.

Additional GEN3 / 02B0 field diagnostic — October 2026

A separate field upload labelled “TSOL-MS800 Balcony” captured an 800 W, two-PV GEN3 / 02B0 hardware profile. Its exact commercial model was not formally declared and no second Home Assistant test was supplied. The MS800 compatibility status above remains based on the independently validated real device.

Logger variantFirmware LSW5_SSL_02B0_1.05, profile 688:Tengsheng_G3 and anonymized inverter serial prefix Y00.
Complete capture144 raw registers, 15/15 successful read blocks and 3/3 coherent snapshots.
Protocol checks17-, 22- and 23-register reads succeeded; both selectors 0x02B0 and 0x0000 worked.
Evidence scopeAdditional 800 W / two-PV 02B0 protocol evidence; commercial model and Home Assistant operation were not independently confirmed in this report.

Local protocol path

TSUN TSOL-MS800 → local network → protocol 02B0 → TSUN Local → Home Assistant
Protocol: 02B0 on the tested unit. No inverter configuration writes are implemented.

Home Assistant setup

  1. Install TSUN Local through HACS.
  2. Restart Home Assistant.
  3. Add TSUN Local from Settings → Devices & services.
  4. Use automatic discovery when available, then verify the detected protocol and telemetry.

Validation evidence

Thanks to @Kmotr for the independent TSUN Local test and anonymized diagnostic. The same hardware owner previously documented the TSOL-MS800 02B0 register map and two-MPPT layout in ha-solarman issue #153. The TSUN Local result is tracked in compatibility issue #52.
