I have installed a Victron Easy Solar 5000 with two Pylontech US3000 batteries and 12x330 canadian solar panels.
In the beginning the system produced up to 3800 w of power but is seems the installer limited the PV to first 1600 w and then to 2600W.
What would be the reason be for this , since I need more PV for my house at midday.
When I asked the installer his reply was that I need to install more batteries then he can "open up" the system. This seems to me not right.

I think the installer is correct.
What you are using during sun should be generated extra, the battery is just not capable of being charged faster.
If the batteries are fully charged the PV Panels are still producing only 2600 W
If there are more load the load is drawn from the batteries and a bit for the grid if the batteries are on 40 % all the load are drawn from the grid and PV
You are best off to discuss this with your installer until you understand their point of view, or if you think they are still doing the wrong thing, seek another local professional opinion.
There could be many reasons to limit the solar. But the only one that matters is your installers reason, and you have to talk to them to try to understand.
One note is that a 40% minimum state of charge still leaves a lot of usable capacity in the Pylontech. They can be discharged daily down to 15%.
You may WANT to keep more in reserve if night time grid blackouts are common.
