My Renogy solar charge controller is showing my battery is 100% charged and my panels are bringing in power. The only things running are a dc refrigerator and the fan for composting toilet. My Victron gauge inside camper is showing my battery is down in the 80’s on percent. Why the discrepancy? Why aren’t 400 watts of solar on a sunny day not keeping that at 100%?
It’s actually a Renogy battery monitor inside camper.
