It's been dark and rainy the past few days so the battery has done most of the work powering Big Trill. When getting up in the morning I noticed two things. First, I had forgotten to turn my outside light off. Second, with it using 1 amp of electricity each hour, the battery voltage was hovering around 12.1 which is about 50% capacity or so. Normally the voltage is around 12.6 or higher and the battery charge is above 80%.
When the fridge turns on it draws 2.5 amps for a short period, but the voltage remains constant.
Once the fridge turns off and the sky brightens up a little the voltage goes up a little, a good sign! This has been the pattern during this period of rainy days.
The good news is the 50 watt solar panel has been able to maintain power and can do so probably indefinitely if I'm careful with my power consumption.
