In the Netherlands, we have a “return delivery fee”.

TWHAT?!?

I have a Sofar 2700TL-G3 inverter.

Sofar are the hardest to control in my experience. :-/

Good evening,
I have a Deye SUN-6K-SG03LP1-EU inverter with Stephan integration and it works.
I don’t see some sensors and wanted to try yours. Which definition of inverter should I use?

davidrapan · January 14, 2025, 7:19am

Hi @Francesco78, you can select Auto.

davidrapan · January 21, 2025, 9:44am

Hi @000al000! Hope you are doing well!

Could you please provide me w/ a result of the following:

In Developer tools > ACTIONS > Solarman: Read Holding Registers (Modbus Function Code 3)
Set Register: 10000, Quantity: 70
Click PERFORM ACTION

Thank you very much!

Awesome! Thank you.

I see you already have 8 packs :

"10002": 8

I will add dynamic reading of all packs (according the register above) in to the repo soon!

It will be displayed as separate device similar to Solarman App.

davidrapan · February 7, 2025, 12:29am

Hi @000al000!

One technical question… are they different packs or modules?

And how does the view look like in the Solarman App?
Or maybe how it’s physically interconnected?

Edit: Can you also show me register reading of 10070 w/ count set to 9?

I have no experience with this, so please help me create some kind of mental concept so I can implement this nicely into the integration, thanks!

000al000 · February 7, 2025, 7:33am

In Deye Cloud it look like sub batteries with main “virtual battery”

“Virtual battery” is presented always, even if only one battery is connected

Physical it’s look like standalone batteries connected by CAN cables

One battery

Four battery (for example)

davidrapan · February 7, 2025, 1:37pm

Awesome! Thank you. And the view of provided values?

Edit: So on the batteries they say MODULE but in reality they are packs w/ each having its own BMS… hmm…

I’m thinking if I should make integration to create just single additional device which will contains all the packs or… separate device for each pack… what do you think?

000al000 · February 7, 2025, 4:04pm

“Virtual battery”

One of ща real battery

For me now i just copy each one of 8 battery to yaml so i have a lot of garbage… But i working

davidrapan · February 7, 2025, 4:23pm

I personally think that because values for whole battery are provided by already present sensors we don’t have to add them again (registers 10000 - 10031).

What we want are values from registers 100032 and above which really brings additional value and those we can add as individual devices for each pack…

Inverter* Battery Pack 1 (as new device connected trough Inverter*)
Inverter* Battery Pack 1 Voltage (as new sensors)
Inverter* Battery Pack 1 Current
Inverter* Battery Pack 1 , etc.

*Name of the device which is set during configuration…

And how many new devices is added will be controlled by reading from register 10002 which defines number of connected battery packs…

davidrapan · February 9, 2025, 3:52pm

Hey @000al000, I just released new version, can you test it out for me?

Thank you!

000al000 · February 10, 2025, 12:35pm

I installed new version, but use own yaml for inverters, so no changes :))
I test default yaml, but later…
BTW count of battery pack may be up to 64

And i read addion data:

I don`t know how decode MOS Status, Warning1, Warning2, Fault1, Fault2, Software version number, Hardware version number but read them Firmware is useful, i updated firmware for my batteries to new version, because of some problem

davidrapan · February 11, 2025, 2:19pm

I have fixed those scaling inconsistencies and added additional sensors (some as attributes). Thanks!

Were the sensors added as separate device(s)?

000al000 · February 11, 2025, 2:47pm

Now, it’s look like early

My config

With new entities

Bimbo009 · February 20, 2025, 2:45pm

I’m currently looking to set the query interval from 5 to 20 seconds or higher. I actually wanted to integrate EVCC via the WiFi logger. I don’t know yet whether this is even possible. I stopped the integration and then tried it but without success. For me, EVCC is still in its infancy.

francisjmm · February 25, 2025, 11:47am

Thank you very much for your work, I find it impressive. Are you considering setting up a Johnray inverter?

raghathol · February 26, 2025, 6:05am

I’m looking to set up an automation system. Specifically, I want to trigger the activation of devices in my home when my solar production exceeds my consumption by 1 kW. For this, I would need a sensor that can provide real-time data on the potential peak production of my solar panels.

Is it possible to configure this kind of automation with the current Solarman software with my deye htbrid? If so, could you guide me through the steps or recommend any compatible sensors that could help?

Thanks to everyone willing to assist <3
