We'll use anything from 80 to 120 Ah, depending on if we use the toaster oven for dinner. That includes hair dryer for my wife, two or three cups from the Nespresso, and maybe playing the HomePod for a few hours, which I've taken with us for the last few trips - sounds great in the trailer. And our 12v fridge, which may draw ~30Ah/day, give or take. So, after a heavy use night and morning, the batteries will be at ~70%, sometimes 65%. On a light night, it might be at 90% when we leave in the am. We can go on ultra savings mode and only lose ~5% of our battery life overnight - inverter off, no more than 2 lights on in the trailer and none outside, meaning the fridge is the biggest draw.
Recharge depends on the conditions. If we're in deep shade like we were last week in the smokies, the solar will basically keep up with the fridge and parasitic draws during the day and so each night will progressively drain the batteries. On a really sunny day, no trees, it might recharge before noon, even from 70%. The lowest we've had it when camping is 40%, I think. We can go to down to ~10% before things start to fail.
We made the mistake last week of doing two heavy use nights in a row while in a shady spot, assuming that when we moved to another campground that we'd have sun. The next campsite was even shadier, so we managed to keep the loss at a minimum for a few nights before deciding to go to a nearby KOA for a night to recharge. That's the first time in 15,000 miles that we had to do that, and had we not gotten complacent about the batteries, probably could have avoided it. And arguably we could have toughed it out without the inverter, but I wanted my coffee and had no backup for the Nespresso. Poor disaster planning on my part.
I'm sure that the smaller panels get shaded by the AC in low sun, but they're connected in parallel so one panel going out doesn't affect the others.
Obviously I like Victron equipment as a combined system; but if even you get a stand alone battery monitor, I think it's hard to beat the Victron BMV battery monitor with bluetooth. It's an easy add-on to the stock Oliver system and gives what seems to be a very accurate reading of the battery state.
