30% SoC is only during the winter months (Late Dec, Jan, Feb) after a couple days of overcast/ rainy days. Our daily usage runs 150-200ah during the shorter day light days. I don't turn the inverter off, that by itself 48ah daily.
This time of year the solar system is producing 5-7kwh daily. I'll switch the Norcold over around 9am till 6pm. Between fridge, laptops, phones, booster, tv, dvd player, there could be 30-40a constant load and still be charging 35-45a. With those loads I'll be fully charged by 1pm. If I didn't turn the fridge over and run extra stuff by 10am I would be full.
