Too many variables for a direct answer including what the starting state of charge is.
Realize that your 55 amp converter doesn't constantly charge at 55 amps.
You have BULK charging which will start at 55 amps on a low battery but slowly decrease as the state of charge increases up to about 80%.
Then the converter should shift to ABSORPTION mode where it applies a constant voltage to the batteries which again decreases the charging rate as the state of charge increases.
Most boondockers find it takes at least 3 to 5 hours to fully recharge their battery bank. This is where solar or a small inverter generator helps in the equation of topping off the battery bank so you don't need to run the big generator for so long.
