Full time vanlifer here! I probably just need to revise some settings but I have no idea what any of it means as I'm new to this.
My setup is simple: One 175w Renogy panel. Victron 100|30 MPPT. One 100AH 12v Weize LiFePO4. That goes to a 1500/3000w invertor. I don't have a Victron BMS. I don't have any extra circuit breakers. The invertor has one built in so it's safe, I think.
I also have a couple 12v DC cigarette lighter style chargers attached directly to the battery recently. They have fuses. But my system worked for a couple weeks with those before something went wrong.
This setup was working great! Until a couple days ago when it died Immediately after the sun went down. I was running my fridge and a small fan all day. I also charged my phone once. But that's it. That definitely shouldn't have killed my batteries. Now it continues to die after the sun goes down.
I have screenshots of my MPPT settings here.
This, as you can see, was the middle of the day.
I checked for loose connections but didn't see anything. It would be nice if it worked again because I have ice cream in my freezer! I'm a newbie at this so please no big words?
