If the device does not respond to Modbus queries, then there is little I can offer in advice. You could test the connection with other software, as explained here for instance: https://github.com/wlcrs/huawei_solar/wiki/Connecting-to-the-inverter#testing-the-serial-connection . It's mentioned as a test for the serial connection, but also applies to TCP-connections. Maybe unplugging and re-inserting the dongle helps? Or you can do a full power cycle of the device (AC and DC side)? |

Has the slave id changed? |

Looks indeed a bit similar as our case. Try an upgrade of the Dongle to at least SPC126 (latest is SPC133). Our 10 kW inverter pair at SPC141 works since longer with that. |

Hello!
Up until yesterday I was on a temporary setup with a SUN2000-5KTL-M1, Everything worked fine with the integration.
Yesterday the company that did my installation received and installed the Intended inverter
SUN2000-10KTL-M1.
Firmware:
SUN2000-10KTL-M1: V100R001C00SPC148
SDongleA-05: V100R001C00SPC125
The Dongle is the same as used with the 5kW interver previously.
I made sure my installer enabled unrestricted access on the MODBUS TCP setting.
Port 502 is confirmed to be open by various softwares.
I removed my existing Huawei Solar Integration with the 5kW inverter
and I am trying to add the 10kW Inverter to the integration without success.
EDIT: [Adding Integration over Network, @ Port 502, tried slave ID 0,1,2. ]
According to logs the connection to the inverter is established but there is a register value
not being able to be read. I do not know where to go from here. My setup is not in the "confirmed list".
Please advise.. I miss my PV data!
