Charge connector or new inverter?

[YHATHANK]

I everyone.
I have an F5000 inverter and 15x 430w Eurener panels(6.45kwh TIC). I’m looking to buy either two fox EP5 5.18kwh batteries or a single EP11 10.36kwh battery. I’ve been made aware that I will possibly need a new inverter, as my current inverter is not compatible with batteries. I have also been told that the F5000 inverter can be made battery ready with a charge controller. What does this mean? And would that mean that I could hook an EP5/11 to a F5000 with a Charge controller?
Thank you.
