The panels are facing SW and SE due to the roof structure of the house. I didn’t want them to put a panel on any north-facing roof.
I was able to talk to them and upgraded my inverter from 7600 W to 10000 W at no cost. So I think I’m in a good place. Thank you all who commented in this thread!

Here is the thing, inverters work less efficient when they are underutilized. So a 10000w inverter may be less efficient than 7600w, if most of the time the power is 5000w. Since your panels are split between SW and SE, it is likely that 7600w would have been sufficient.
You can download software called SAM, and do a simulation with the two inverters. Although I suspect the difference will be negligible either way.
Of course getting a larger inverter will allow you to upgrade to a larger PV array in the future. So go for it.
