Amount of Solar for AC 300 in Split Phase

Hello, I have an AC 300 with 6 340v solar panels split between the charge controllers. I wish to add another AC 300 for Split Phase operation. Can I add the same amount of panels to the second Ac300 or am I at the maximum? Thanks

An equal number of solar panels can be added. The PV inputs of the two AC300s are separate and independent.
