Faster Battery Charging
My son has 2x GC2 batteries at 232AH and a WFCO 8955 charger and it’s about 20’ from the batteries. While he also has 160W of solar he wants faster charging with the charger and 2KW gen with reduced g...

MPPT for an array that small is a waste of money. There does need to be a charge controller for the Array, but a PWM is cheaper, and will likely work better than the MPPT.
GC2 battery charge voltages, wired as 12v, 6v is 1/2 totals:
Bulk: 14.2
Absorption: 15.3
Float: 13.4
Equalization 15.6
It doesn't matter what the charger / converter kicks out a far as voltages. With wire voltage loss what matters is the voltages AT the batteries wile charging.
As mentioned, with 20' from charger to batteries, you would need very thick wire to be charging at proper voltages.
