Don't forget you have to add more AH in than went out just to stay even. Charging efficiency. That varies over the SOC range. On my Trimetric monitor I find I need to go to about 15AH "over" to get to the point where the batts (about 430AH worth of open flooded) are full by hydrometer count.
The Tri has an adjustment for that if you fiddle with it and every day were the same. (they aren't of course) I don't bother. If it gets to about + 15AH and solar is done for the day, I reset the Tri AH to zero. (on solar don't leave the Tri in auto-reset!) If it doesn't get that high, as is often the case on partly cloudy days, I don't reset the Tri. Only reset when you know your batts are full---not when the bogus Tri instructions say "full" is.
