Is your feature request related to a problem? Please describe.

I am extending the number of panels of my installation using the garage roof. With the extension I am going beyond the maximum number of allowed (Hoymiles) ten inverters. I would need to have 11 :-(

Describe the solution you'd like

Any chance to get the maximum number of inverters increased in the standard "opendtu-generic.bin" (at least to 14).

Describe alternatives you've considered

Thanks to a running discussion in German I am aware of adjusting the file:
OpenDTU/include/Configuration.h
old: #define INV_MAX_COUNT 10
new: #define INV_MAX_COUNT 14
It is mentioned that more is not possible because of the config size.

The other alternative of adding additional OpenDTUs would be possible but if there is a way around I would appreciate it. The integration into Home Assistant would be simpler staying with one piece of hardware

Additional context

It is limited to 10 because of the available memory in the ESP32.
But you are free to test it with 14. I will not increase the value because of possible stability issues.
