OK Steve,
Hang on....
This is the simple answer of what they are telling you:
Put the converter/charger as close to the bank as you can. (A)
Run the 120V power to it in the same size wire that is there and from the original breaker. (B)
A - You need to be close to the bank to cut the line loss that will make the charger less capable. I.E. a 0.5 volt drop (what you will get with 30 amps on 18' of #10 wire) will cut a 50 amp charger to about 30 amps and there in nothing you can do about that but shorten the cable and/or make it heavier - Lot$ Heavier.
B - The power requirement will still be about the same on the AC side. This is because the current will be 1/10 of what it is on the 12V side.
If you install that 100 amp charger correctly, it will be too large for a pair of GC2s. The heating during a hard charge will shorten their life and increase the water replacement required.
If this did not clear things up, try again, I'm here a lot.
I did goobs of boat work before the depression, and this sort of thing came up a lot.
