Just FYI, the average home uses 6 times this much power per day. This is great for some uses, but do not count on using this as a replacement for a generator.

I think that was the downside of the Mega 5.

I have the Mega 3 and my main use is to power the refrigerator and freezer. In an emergency, that would be my focus.

this would work well for me if I'm gonna pack for the whole house, I don't dry my clothes anyway. I just wash and hang them up, clothes last a lot longer when you don't expose to extreme heat.

Whatever math this is based on is wrong. Average US household energy use is approximately 30kwh a day, so technically only three times as much as this system.
