COMMUNITY VALIDATED ON REAL TSOL-MS300 HARDWARE

TSOL-MS300 in Home Assistant — validated local 02B0 monitoring

A real TSUN TSOL-MS300 has been validated with TSUN Local, confirming the 02B0 path, one detected PV input and coherent 300 W telemetry on independent hardware.

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 validation@nxenara supplied repeated read-only hardware dumps from a real TSOL-MS300, consistently identifying the 300 W unit on the validated 02B0 path.
☀️ One PV inputThe tested TSOL-MS300 exposes the expected single-input telemetry path with coherent PV voltage, current and power values.
🧩 Tested hardware pathSerial prefix Y00, logger firmware LSW5_SSL_02B0_1.04 and logger profile 688:Tengsheng_G3.
🔁 Repeated evidenceSeparate captures reproduced protocol 02B0, rated power 300 W, maximum designed power 300 W and plausible live AC/PV telemetry.

Local protocol path

TSUN TSOL-MS300 → local network → protocol 02B0 → TSUN Local → Home Assistant
Protocol: 02B0 on the validated unit. Rated power is reported as 300 W. No inverter configuration writes are implemented.

What the validation confirmed

AC telemetryVoltage, current, frequency, power and daily energy were present and plausible in the supplied captures.
PV telemetryThe single PV input returned coherent voltage, current and power values across repeated captures.
DiagnosticsInverter temperature, rated power, maximum designed power, output coefficient and logger metadata are available through the 02B0 path.
Model assignmentThe 300 W hardware signature uniquely matched the declared TSOL-MS300 within the contributor's multi-inverter test set.

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 protocol 02B0 and the single detected PV input.

Validation evidence

Thanks to @nxenara for the independent TSOL-MS300 hardware validation and the repeated read-only dumps provided on 2026-09-14. Those captures confirmed the 02B0 / GEN3 path, one PV input, 300 W rated and maximum designed power, serial prefix Y00, logger profile 688:Tengsheng_G3 and logger firmware LSW5_SSL_02B0_1.04.
