How do I get started with an inverter that is not yet supported - SunGoldPower SG10KHB-48

[jas67]

I have a SunGoldPower SG10KHB-48 hybrid inverter.

Sadly, I didn't research HA and SA support for inverters before purchasing this.

This might be a brand-labeled SRNE, but, I'm not sure.

Any help getting me started would be greatly appreciated!

If none of the existing profiles works you gonna have to get modbus rtu documentation from your manufacturer. 😉

Hi ! I've got SRNE inverter, also I've got modbus documentation, what the right algoritm to make new profile ?

Proly to copy over some of the existing one (e.g. deye_p3.yaml) to custom/ subfolder under inverter_definitions/ and update register addresses (and remove unrelated sensors) according to your documentation. 😉

I do it . I use for probe some registers but have got errors.
-are there any important registers?
-Do I need to restart the HA every time I change the inverter type in the settings?
-2 windows appear in the integration - is this correct?

Not really.

Do I need to restart the HA every time I change the inverter type in the settings?

No.

2 windows appear in the integration - is this correct?

I don't know what you mean.

Thanks for help
I solved my questions
now i get data from inverter !
features of SRNE inverters are 32 registers that can be read in one sequence, i think it would be good to describe in help where it changes
Now i have a question: my inverter does not have registers like Today Battery Charge (kWh), but there are registers like BatChgAHToday (AH) and BatVolt -- how can i multiply them and get kWh? i am not strong in programming. thanks

Does this software connect to the inverter through the logger stick as it comes from the factory, or is there something I must do to enable access?

I can obtain the IP address of the stick from my router. How do I get started with trying to make modbus TCP requests from my inverter to start to try to get this working on my inverter?
