Huawei SUN2000L

Post by stealth » Wed May 13, 2020 10:54 pm

Hi all,
is possible to use 123solar to monitor an inverter Huawei SUN2000L?
I connected this inverter in my network using WiFi and I discovered it; the goal is to monitor it using 123solar directly from WiFi network connection.
I already use the same installation of 123solar with another inverter, SMA in this case, and I use SBFSpot to connect
Thanks in advance

Hello,
If you can get data, it can be supported by 123s. Can you give me some data samples and url request ?

Hi Jeanmarc,
thanks for your response.
I can get data using an app on mobile phone when I'm connected in my wifi.
I see the inverter have the tcp port 502 opened but i don't know wich kind of connection I need to use to communicate with it.
Can you help me?

Hi,
I don't know about the LAN request, can you access it from a PC ? If so, in chrome press F12 > network and see what it request.
If you can give me data sample either from LAN or via RS485, it's should be fine.

Hi,
I see the port tcp 502 (Modbus) but i don't know the command used from the phone application.
Is there any protocol usable in 123solar inverter config?
I can't use the serial cable because the inverter is in a different building than my 123solar logger

It's not because you can read data from a propriatry application than you can decode the data. Once for all, i don't write com app :think:
The port is like a door nothing much.

With Android, maybe try https://developers.google.com/web/tools ... ging?hl=en or https://play.google.com/store/apps/deta ... ture&hl=fr
With RS485 cable, maybe get a try with https://www.modbusdriver.com/modpoll.html and try to read good registers.
