By using Modbus register 56 I can toggle between "low" and "high" frequency as per PV / ESS assistant setup, but I would like to have more than one option.
If possible I would like to write 3 Freq values between 50Hz and 52Hz.
- 50.6 Hz
- 51.2 Hz
- 52 Hz
Is there a register that is not on the common Modbus Register List that allows this functionality?
The end goal is to do load control via frequency shifting over a large off-grid network.
