MPPT PV charger limitation

I have system with 6000Wp of panels (two strings parallel. In each string 8x375Wp serial) connected to MPPT 400/100 PV charger. System is with two Pylontech US3000c batteries and with Multiplus II 48/5000/70-48.

My problem is that I can't see production from PC charger bigger than 3,6kW. Is this power limited by batteries where maximal charge current is 74A ? Or what can be reason? When I will switch on appliances is sume of 4kW, 3,6kW is directed used from PV charger and 0,4kW from batteries.

In this case in theory the panels should produce more power.

But is the sky clear? Which direction are the panels facing?
