Hello,
I have a new Huawei SUN2000-6KTL-1, I am using Huawei FusionSolar Android App to setup and configure inverter. The inverter integrated WiFi is configured and connected to my house WiFi.
Firmware is updated (software version V200R001C00SPC124 and MBUS firmware is to V100R001C00SPC320). Modbus TCP is enabled unrestricted. The installer password is set.
I can open TCP connection from computer to port 6607. Slave ID is 1. Additional Huawei power sensor is connected and visible in the app.
After HACS and wlcrs/huawei_solar installation. I am unable to initially connect - “Reading from the inverter failed” . In logs I see:
logger: custom_components.huawei_solar.config_flow
Source: custom_components/huawei_solar/config_flow.py:114
Integration: huawei_solarCould not read register value, has another device interrupted the connection?
Traceback (most recent call last):
File “/usr/local/lib/python3.10/site-packages/huawei_solar/huawei_solar.py”, line 356, in _do_read
response = await self._client.protocol.read_holding_registers(

File “/usr/local/lib/python3.10/asyncio/tasks.py”, line 445, in wait_for
return fut.result()
pymodbus.exceptions.ConnectionException: Modbus Error: [Connection] Connection lost during request
What other devices / connections is possible to have / how to disable them?
Should I disable Huawei cloud connection inside FusionSolar app (“Management System” connection to EU / global servers)?
I can use the mobile app and device commissioning as installer with password on the same/home network. If this “device commissioning” needs to be disabled, how to do it?
