Don't know why you are downvoted. I used to run solar powered sites that would have 5 rainy days in a row in which only about 10% of solar generation was delivered during daylight hours. We started with only enough batteries to last overnight and ended up with 10x that. Then we added 33% more when the first set of batteries had a short life due to getting so deeply discharged.

Is 10x overnight demand close to 48h of average demand? If yes then original post was right.

My average day and night load was the same so I went from 12 hours to 120 hours worth of batteries and then could get through the 5 day storm, but with batteries depleted so badly they were essentially damaged. Now we have about 150 hours worth of stored energy for our loads.

we added a wind turbine as well which was great since some of the rainy stormy days had lots of wind. I don't understand my original posts parent's comment about (geo) diversity not helping.

He’s downvoted because he’s bringing on-the-ground facts to a political discussion about solar and wind.

It may have more to do with the "haha lol", which is an antipattern for rational discussion.

Humans are irrational. And it’s hard not to laugh at wind and solar.

But you are right. I would downvote if I was wrong and laughed at.
