Hi

Just added my Growatt Mod 4000TL3-XH to the Solar Edge App. The inverter connected well but no values are displayed. Any suggestions what I can do?

I think you better can ask it in this topic.

hey,

just to be sure did you do this , it does not have modbus support out of the box.

and also can you send me a diagnostic report

also I hope the app will be pushed tomorrow and then I can start changing the official forum.

Is it me, or are you using the wrong app? Growatt is not the same brand as Solar Edge?

The Growatt inverters work with the solar panels app:

Solar Edge just mentioned a couple of weeks ago that they are supporting Growatt as well. However I have SoloarEdge at my house in Switzerland and here the screen looks the same. No Values

The App connected very well to the Growatt and Solar Edge system bit does not show anything

it is about modbus tcp, all inverters work the same , only different registers mostly

do you have modbus installed and enabled like in the pdf? and more stuff is coming to control your inverter.

Ok, nevermind, learned something new today :slight_smile: Thanks!

Need to ask the Provider if modbus is installed. I habe no idea just installed the App on my homey. Will Check let you know

probably not , this is a hobby solution and not a professional device. you can buy it somewhere

I have a client asking for a solution of making a remote automation running his Growatt battery storage. The Homey and your app looks like an solution. A question, is the KMTronic always needed, also for a 10KTL3-XH?

As I understood your app it will be able to control the charge from AC and discharge, with different times and also set power limits, correct?

Thanks

Hey

for growatt I think it should work, I am solaredge fanboy and don’t own growatt but indeed you need a device so homey can do modbus comm and talks to growatt. But what I see and heard, Growatt can handle almost all devices. many people uses other devices than KMTronic

Off course , the test version of this app has pull requests of growatt users and they do some complex advanced flows. with SOC and dynamic prices , or not allowed to deliver back

But check the growatt modbus registers for your device and also home assistant forums. But like always installing it , make it work is 1 thing but fine tuning with PV, dynamic prices is another thing and always takes a lot of work.

thanks Edwin

Thanks for the reply, I’m aware of the programing
of flows etc, it was just a question if the modbus interface was needed for all Growatt inverters but then I understand, thanks for the info :+1:t2:
