Huawei Solar Setup

See attached images.

2 Inverters: SUN2000-10TKL SUN2000-8TKL

Smart Meter 3phase

Huawei Luna 10 kWh battery

SDongle

Describe the issue

When trying to connect through Network via SDongle (double checked IP in my TP Link Deco M5) I get an Error for one of my inverters (the master inverter where my battery and SDongle is connected). When trying to connect just my 8TKL inverter the integration works fine. But as soon as I try with my 10TKL, either isolated or both of them with comma separated slave IDs I get an Error.

Have double checked the slave IDs in each Inverter as seen in the snaps above. SlaveID no 1 = 8TKL Inverter SlaveID no 2 = 10TKL Inverter Have also tried both ports 502, 6607 and also with on/off in all the variations with setting “elevate permissions”. Also triple checked in both Fusion Solar and app in Inverters and Dongle that Modbus is set to Enable Unrestricted.

Lost for ideas now so I`m reaching out for help here :)

This is a well done bug report. Thank you for that.

So when you setup the integration with the combination: 192.168.68.125, port 502 and slave id 1 it correctly sets up the integration for your 8TKL inverter?

In that case I would expect that "1,2" is the correct value to put in the slave id's fields.

If you're still experiencing issues. Please post the full logs (including pymodbus logs) where you first setup the integration with the 8KTL alone, then remove the integration again and try to setup again with the 10KTL included.

Note: I don't have an SDongleA or second inverter in my own installation. I've implemented support just by reading the technical manual, but without being able to test it in practice. I need proper logs of actual owners to understand how the system behaves in all possible configurations.

BIG thanks! Opposite order works, i.e —> “1,2”. Think it´s the only variation I haven`t tried and should have been the most logical to try :)

So at least in my case the Master Inverter (Slave 2) wasn `t the that should be first in order.

THANKS!
