Not updateing Invertor Solis Hybrid

[OneScuzzie2k]

I have a Solis Hybrid 6KW with Solarman, its working great reading all the information, I am trying to write back using modus for example to 43143 and 43144 to set Timed Charge Start and End, it seems to update on the Entities on HA, but the invertor does not change which I do not understand.

I have tried solarman.write_multiple_holding_registers and solarman.write_single_holding_registers all seem to update the relevant fields in the sensors but not the invertor
