Looking at your setup again... I would bet the culprit is your AGM batteries. They hate being deeply discharged, and it doesn't look like you have a dc regulator after the battery which would prevent this.

Good advice..👍
I’m not following how a regulator in and of itself helps. What you need is some circuit to prevent leakage once you hit some threshold (Undervoltage Protection). I suppose it could be a regulator but could be much simpler
A caveman tier solution could be just unplug the battery if you know you’re not gonna use it after at least a week bc what probably happened was you leaked a few mAs for like a year a went into deep discharge nostr:npub1h8ktyt8zvqc8dcpk7yh9gq6fs0csqcujlkqdwwspwgtef9ral6xqzugdky
I am taking it to camping world today 😬👀
I would honestly recommend looking at an all-in-one solution, I have used several Bluetti units and I can't say enough good things about them.
