Battery Sizing Validation

Hi all, working on sizing my battery packs and this is what I have worked up for consumption.

I am looking at two 214Ah AGM marine batteries to begin with for a total of 428Ah. I can expand it if needed. I will have solar, probably in the range of 1.1KW

So... Looking for people to set me straight on capacities and suggestions where I am leaving things out.

In the solar section, the chart shows it will take 17.6 hours to charge. I am assuming that is how long you need to have your solar panels generating electricity to supply the expected load. However, 17.6 hours is not realistic. Perhaps 4 to 6 hours depending on your location and angle of insolation.
