Why I am getting only 440Watt? Mppt 100/30 , 3 x165 serial and 2 Parallel ,Total 6 panels.

In my solar system, I connected 3 12v 165W panels in series. I also connected the panels connected in series with the same value in parallel. In summary, I have a battery charging power of 6x165 watts with a total battery charge of 990W. I have a 100/30 Mppt Smart charge controller. My battery is 12Volt 400 Ah lifepo4. At noon, I get Max 420 Watts of power on my Maximum mppt device. My panel direction, angle and outside temperature are at the required values. Why can't I get 800-900 Watts of power? What is the reason ? How should I connect the panels? Could I have a mistake?

My inverter is 12 Volt 1200 Watt Phonex.

It is 30 Amps max you can get from your MPPT into the 12V battery.
See the data sheet.
You would need a bigger MPPT or one more MPPT in Parallel and divide your panels
