TSOL-MP3000 Home Assistant — Local Integration

✅ VALIDATED TSUN HARDWARE

What TSUN Local exposes from the MP3000

The TSOL-MP3000 is a validated reference device for TSUN Local's TITAN / 1511 support. Home Assistant entities are created from the data actually returned by the inverter.

☀️ Six PV inputsVoltage, current, power, daily energy and total energy for the detected MP3000 PV inputs.

⚡ AC productionAC voltage, current, frequency, power and energy information.

🚨 Readable alarmsActive inverter alarms can be presented as localized descriptions with stable diagnostic codes.

📡 CommunicationOnline state, last successful communication, duration and consecutive failures.

🧩 Device informationFirmware and inverter information where exposed by the native 1511 blocks.

🛡️ Advanced diagnosticsAdditional read-only diagnostics remain disabled by default until you choose to enable them.

Validated local protocol path

The MP3000 support is based on repeated read-only captures from real TSOL-MP3000 hardware. Native 1511 blocks for inverter settings/status and PV1 through PV6 have been read successfully.

TSUN TSOL-MP3000 → local network → TITAN / protocol 1511 → native read-only blocks → TSUN Local → Home Assistant

✅ Real-device validation includes PV1 through PV6. The native A3/A4 blocks have been read successfully on the physical MP3000, including the per-input daily-generation positions.

Read-only by design

TSUN Local is intended for monitoring. It does not implement inverter configuration writes, country/profile changes, grid-protection writes or inverter control commands.

Normal Home Assistant useProduction, energy, communication, alarms and device information remain the everyday interface.

Expert diagnosticsAdditional field-validation and grid-related values stay read-only and are disabled by default where appropriate.

Install through HACS

For normal use, install TSUN Local and let the integration discover the compatible inverter on the local network.

Technical documentation

The public documentation keeps detailed protocol and field-validation evidence separate from the normal Home Assistant setup path.
