Inverter-charger upgrade inquiry - Help Needed!

I've been upgrading my DC electrical system on my 2002 Beneteau 411, which I purchase out of charter. My vessel now has a high output 120 amp Alternator with a smart regulator (ElectroMaxx), a Sterling Power digital isolator, and a digital battery monitor for system management. I've also upgraded my house bank from 200AH to 480AH with the 6V Trojan T-125 batteries. However, I did not upgrade my 20 Amp Dolphin Battery Charger.

My vessel has 220vac electrical but I'd like to add and inverter which could meet my 110 vac needs which are minimal, i.e. computer, cell phones chargers and maybe a microwave, when I'm cruising.

Maybe I'm complicating matters, but the answer I'd like to know if I could install a 120 vac 1800-2000watt/30-40 amp inverter/charger and still maintain and operate the 220 vac system on my boat when I'm on shorepower to run my A/C. This way I can upgrade my battery charger to 40 amps & have the benefit of 120 VAC when I'm cruising. How complicated would such an install be?
