About eleven months of the year I depend exclusively on solar power for electricity to charge my laptop, phone, hot spot and camera. The system works like this:
But sometimes I have shore power, like during the past month at Forrest's place. Since I'm parked in a shady spot, and since there has been a lot of overcast, I've been using shore power, via a battery charger, to keep my house batteries charged. The primary thought in my old head was, "Keep the house batteries charged," so it took me a while to realize I had an even sillier setup when it came to charging my electronic devices.
Too bad my refrigerator is DC-only. Otherwise I could just plug everything directly into shore power. Ah well, van dwelling means compromises.
