Night has fallen.
With everything off but the fridge, I am drawing 1.0A. Normal is 0.5A. So in the 13 hours between no solar charging whatsoever and charging starting again, I will go from losing 6.5 to 13A. Not a huge deal, that’s only 1% battery capacity. But where is that phantom draw coming from? Perhaps my truck battery that mysteriously has the exact same voltage as my house batteries?
We’ll know more in the morning. L and I are going down to the saloon for a few beers and I’ll see where things are after a few hours of nothing but the fridge running.
