Want to add another string to flat

[HowTo]

Hi all

Want to add another string to my current setup.
Flat 5kW Sunsynk inverter.
6* JA 455W panels.

What to look for. 5kW inverter 13A +13A MPPT.
Most panels over 600W all exceed the MPPT amps of a 5kW system.

One explanation I received.
Sum of panels not to exceed 5kW?
Current 455W *6= 2730W
Other String 460W*5=2300W
Sum of both 5kW does this make sense?
