Fake news said that perpetuum mobile is not possible. Take that, naysayers!

Ah yeah, the ability to pass power in both directions at arbitrary rates seems pretty important for that use case. Otherwise you'd have to charge the battery with the sun, discharge the battery into the car (while presumably wasting good sunlight). The setup you have sounds like it avoids most of that.

So a good sunny day is good for what, 3 kwh into the car?

I’ve gotten as much as 4, but 700w of panels can vary… shade and heat play a big part in it. I also wasn’t super vigilant of putting up my portable panel, unless I knew I needed the power. When it was up, I generally got about 2.5, but it performed better when I was in places like the Mojave desert and the sun was completely unobstructed all day.

I also charged at a lot of level 2 chargers across the country, that are usually free, and could put power back on the 2kwhr pack from the cigarette lighter outlet in the car, so I generally stayed topped off before the sun even started shining. That’s why I didn’t always use the panels. Not necessarily something to plan into a daily routine if you aren’t traveling. It was a trade-off from having a level 2 chargers at my house.
