Hi everyone, this is my first dip into HAOS world, although I’ve been in home automation for a while now.
The first thing I wanted to do is integrate my 2 existing inverters with built-in Wi-fi modules (a SUN2000-3KT and a SUN2000-6KTL) but I’m having difficulties having them both connected to home assistant at the same time.
Let me explain my setup and and I tried so far.
I have these 2 inverters, that are daisy chained via serial cable.
Both of these inverters have built-in wi-fi module (no separated dongle), that are both connected to my home network.
I do have installer access to both inverters and can change whatever.
What I did so far:
- I installed the wlcrs/huawei_solar/wiki
- and according to wlcrs/huawei_solar/wiki/Connecting-to-daisy-chained-inverters I checked both inverters through sun2000 app and they are both using the unrestricted TCP mode.
- I connected HA via a USB wi-fi adapter to SUN2000-6KTL which I think (but not sure how to check it) is the master. ( i do have the power meter connected to it)
- I opened the Huawei Solar integration and connected successfully from the first try to SUN2000-6KTL 192.168.200.1, port 6607, slave id 0. (even though the Comm address was set to 1)
- This successfully generated 2 devices (the 6kw inverter and power meter) and about 40 something entities, but no 3KW inverter.
- When i checked in the sun2000 app both inverters had Com address set to 1. So I changed the SUN2000-6KTL to 6, and left 3KTL to 1 because I though this might be an issue.
- I then deleted the integration and tried again but this time I tried all sorts of number combinations in the slave ID’s field (0,0 then 1,1 then 6,0 then 6,1, the 0,1) with no luck. following the guide from here Connecting to daisy chained inverters · wlcrs/huawei_solar Wiki · GitHub
- I even plugged 2 individual wi-fi adapters into the hass server and connected each to an inverter. This part worked, but apparently when going to the Huawei Solar under Settings ->Devices and services → add new entry, → Network, and when I attempt to connect to the second inverter, it times out. So I think the plugin doesn’t know which adapter to use and it attempts to connect to the same first inverted that I added first, since both have the same 192.168.200.1 ip.I’m sure I’m doing something wrong here
Conclusion, I can successfully connect and add to hass one inverter at a time, but I cannot add them both.
Ideas?
