What do you need to know?

Renogy solar adventurer control. I haven't used my van in a few months - everything prior was fine. It's been sitting in the sun the entire time. I've been getting an E01 error off and on and my dometic fridge cooler won't power up. Looked up the error which means the batteries are being over discharged. Not sure what to do next? Multimeter to check the battery?



11.5 volts! That is super dead. I would check the easy stuff first. Disconnect your panels and check that you have voltage ( usually an 18v panel will output 23v when not loaded). If your panel work check your connectors. Then check your wires for continuity, putting a lead of the voltmeter on each end looking for 0 ohms.
Let us know how it goes
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..π
Iβm 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 youβre 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 π¬π
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.
