Describe the bug
PV_OPT keeps trying to set my inverter import/export current above the 100A limit of my inverter.

Expected behavior
I would expect PV_OPT to either retrieve the maximum value from the inverter or the config file and ensure that the value passed for export does not exceed that value.

HA version:
Core 2024.2.2

It looks like this is at least partially because the discharge power is being rounded up from 4840w to 5000w. In 3.8.10 try setting the Power Resolution to 0 (it will probably cause a divide by zero error in previous versions) and let me know if that helps. The trouble with the Charge Current Limit is that it is set dynamically by the BMS.

I'm afraid this is still happening.

My next charge is calculated at 102A, which cannot be written to the inverter as the limit is 100A.

Can a limit be set that caps the optimum charge current value?
