F4600 model RS485 support?

[gcmvanloon]

Hello,

I'm currently using Open API to get measurments from my inverter and that works.
However, I'm looking to get more accurate readings with a higher interval than the 3 minute interval provided by the API.

The documentation (page 19) of my inverter mentions connection with a PC over a RS485 connection.
So I bought a USB RS485 adapter and tried to get some readings.

I have not been able to get any data from the inverter to this day. There is no documentation (i'm aware of) that describes the registers (modbus?) that can be read or how to read them.
I'm beginning to doubt it the F4600 model is even capable of rs485 communication. (it has the proper connector for it though)

Does the RS485 communication need to be activated in the menu somehow?

Some help would be greatly appreciated.

This probably isn't much help as I don't know whether the F series supports modbus, I do know the T series doesn't, instead it simply transmits data packets on the RS485.

There are a couple of projects out there for the T series https://github.com/LucasTor/FoxESS-T-series is the most popular for the T series and seems to be maintained, also this one https://github.com/assembly12/Foxess-T- ... -Assistant - this issue appears to confirm that the F series isn't compatible https://github.com/assembly12/Foxess-T- ... /issues/14 but they have developed something that might help.

That last link was a very interesting read.
Thank you for keeping hope alive!

‘Happy’ to see more people have the same need for developing next step in automation. I did some testing with rs485 to lan/wifi but no luck on anything what looked like a converter parameter read. Did get the f3000 in a bus error twice so you should think something is happening on the bus..

Curious to experiences of others, look forward to replies on this thread
