Do I have this right? (Adding Battery to Existing System)

My system has been up for a few years running 14 panels on IQ8+ microinverters coming down to a Combiner Box 5. We don't have A/C where we live and the panels have lowered our electric costs by over half but we still get boned during those peak times, 4pm-9pm, at .56c kWh.

I am looking into adding the newer 10C battery but it looks like I will need a few other things to make this work. Hoping I can get the confirmation or clarification of what is needed.

-Remove Combiner Box 5 and switch to Combiner Box 6C.

-Call local electric company and have them install my provided Meter Collar Kit

-Of course install new 10C battery

Is that basically it? Thanks
