Hi BFL13,
175 amp-hours per day / 24 =~ 7.3 amps per hour. (but we don't know how that 175 amp-hours has been arrived at)
During the day time (lets say 10 hours) all of that 7.3 amps is going to be provided by the solar panels.
That leaves approximately 102 amp-hours to be replaced.
The 55 amp charger less the 7.3 =~48 amps to replace the 102 used from the bank.
The bank is AGM and they start to taper at about 95% state of charge. The bank is 830 amps so the last 5% is about 41.5 amps. He gets 55 less the 7.3.
I can see no reason why a generator needs to be run at all under that scenario unless there are several rainy days in a row.
The controllers are less than optimal. I used the voltages from the flooded choice.

I have not done a detailed calculation (your job) but I doubt you can restore 175AH during daylight with only a 55amp charger. Just not enough time in the day. Most folks in that situation have to run their gens and use high amp chargers for an hour or two in the morning before they can leave the rest to solar, and hope to get to full before dark.
