What is the results of the energy audit you did? Understand that using solar/battery versus grid or generator that ratings are not what you actually get. You need to allow for all the losses. So as example your energy audit shows need of 500wh per day. Your system will likely need to be able to develop at least 3-4 times that in order to account for losses, loads and return to a state where you can start the next day without being already partially depleted. Thus 1500 to 2000wh. Does your design incorporate all of this? If not than every day you have to subtract from your battery the amount you do not meet full restore capacity from solar. This will give you run time until a generator or shore power becomes available.
A 206ah 12v battery is able to deliver 10.3 amps for 20 hours before completely discharged (10.3 *12= 123.6 watts per hour for 20 hours). Or it can deliver ~2400 watts in 1 hour before dead.
ETA: There is also one other factor that I forgot to mention. Your panels might be sufficient to recharge your battery and supply loads during the peak of the day. However any additional power they could supply is lost once your batteries become charged. The panels no longer see the battery as loads. Amount of storage and amount of generation for loads is a strange dynamic.
