Not sure why you are not able to poll. Were you using the correct slave ID 100?
See image below for parameters to read register 2705 for example, I get response value 12, which is correct for my system.

I am not sure what you are doing wrong. As you can see above it is working well for me.

No option to writable registers for charging current to the MPPT.

You can write DVCC charge limit which is a system charging limit, write to register 2705 for this.
