Two Renogy 100W panels, one Renogy 200ah battery, Renogy Adventurer charge controller.
I think I'm having an issue with my battery or charge controller or something is actually draining my battery very quickly. My battery has been hooked up for a few weeks and I've been using a few LED's for light while working on it in the evening with not much noticeable change in the % battery charge.
Yesterday we hooked up the solar panels and took the van out for a few days. I'm having huge swings in my %battey and volts according to the charge controller readout. The only load I'm running continuously is a Truckfridge 130. We've run the water pump in the last 24 hours a total of only about two minutes at about 10-15 seconds at a time.
I've gone from nearly 100% to about 50% in about 30 minutes today with nothing running but the fridge. Does this seem right? That's about 100ah drained in 30 minutes from just the fridge. Below are a few notes in readings from today. Any idea if I'm having some kind of a problem?
