Site limit control not working or lagging behind

[Macgregorsound]

Describe the bug

When changing the site limit of the setup, the active power limit goes to 90% and the system does not listen to the site limit value. Sometimes after 2 hours it will respond and start working as expected.

Expected behavior

Site limit is set from 55000W to 200W max export, the system should then start to run in zero-export mode (solar keeping up with internal consumption)

I think to change the Site Limit (solaredgemodbus_i1_site_limit) you need to send a "Commit" and that effectively resets the inverter. It isn't a viable thing to change regularly because of this as it takes 1-2min to come back online (on my system at least).

If you want to stop the system generating/exporting energy, then the way to do that is by using solaredgemodbus_i1_storage_discharge_limit as that doesn't require a restart of the inverter and takes effect quickly.

my HA entity 'number.solaredge_i1_storage_discharge_limit' is not available. Has it changed identity?

My retailer remotely curtail export at negative FiT, by the look of it by dropping Site Limit to 0. If each change incur a reset, @cyberkryten, I will reach out to the tech team at the retailer to change their approach, if I can make it work myself first.
