Describe the bug

Plugin connects to the inverter correctly, though throwing a warning, and all values remain either 'Unknown' or just 0. Behaviour is since 2024.12.01 but I had not updated since the breaking changes HASS version 2025.1.0. Reverting to a previous version fixes the issue.

Integration Version

2025.01.6

Homeassistant core version

2025.1.0

Inverter brand

SolaX Power

Plugin used

plugin_solax.py

Serial prefix

MC208T

Inverter firmware versions

ARM 1.15 DSP1.18

Connection Method

Waveshare Adapter

Dongle firmware

V1.452

Additional context

The following solutions I tried without success:

  • Restarted inverter & RS485 adapter
  • Reconnected RS485 adapter
  • Run without PocketLAN (v3) connected
  • Restarted home assistant
  • Reconfigured inverter in home assistant
  • Removed and added the inverter back in home assistant

Reading the holding register 0x318 (0d792) returns 0x0000 in Open ModScan.

Have same issue with X3-MIC Gen2. Added some logging and enabled debug modbuspy, but not sure what the output means for now.

If I try same 0x351 with nodered modbus I get:

Which seems correct as old version was displaying this value as 11000W

Found the issue, at least for my inverter:
Device info
X3-MIC
by SolaX Power
Firmware: DSP v1.117 ARM v1.113
Hardware: Gen2
Serial number: MC210TIXXXXXXX

Registers 0x367 and 0x371 are not supported (anymore ???) by the inverter and return error. After updating allowedTypes for the registers to GEN3, so it does not get picked for my inverter, the plugin started working.

It was this commit which added unsupported registers:

Nice! I tested this on my instance as well and I'm finally getting values again! I'm not sure if I can implement this fix tho, I don't know the codebase well enough for that.
