If you're connecting your shore power cord to your generator, you will only get charging capability up to whatever the Progressive Dynamics converter can provide...45 amps DC in this case.
Watts = volts x amps
630w = 14v x 45 amps (the charging DC voltage will generally be around 14v)
So the PD converter will be drawing around 630 watts.
If you have an 1800w generator, it looks like your generator will be capable of outputting far more than the PD converter can actually use.
The only way to take advantage of your generator's full output for battery charging would be to run it through a different battery charge controller capable of handling that higher output.
1800w = 120v x 15a (AC)
1800w = 14v x 128a (DC)
Theoretically, your generator could supply up to 128 amps of DC current at 14 volts. That all depends on whether some separate battery charge controller could even handle that much current and whether your battery bank is large enough to charge at that rate. Plus wire hefty enough to handle that current.
