I see, yes that's possible. I thought it worked the other way, basically it gets the power from the sun and the remaining from the grid.

What do you mean by "ev rates"? Where I'm based (Italy) I don't think we have those, you just pay based on the kWh you use. How do grid tie inverters work?

Yeah a battery in between will solve many problems. However as I said usually these EVs don't accept currents below 5A (from a 240V system) aka below 1.2KW. So even if you can get a higher voltage than the battery (>400V) with a converter the current would be too low.

Hi, someone told that 100W is not enough to power the charging system to actually charge the battery so that would be one of the reasons among others why this is not allowed.. Anyway it would have been cool to get "free" charge from solar directly at your own house just to experiment with cheap...

Have I asked something so idiotic as a beginner? :rolleyes:

Hello, I was thinking of creating a simple 12V 250W solar panel with an inverter to 120V or 230V AC to charge cars like the Volkswagen e-up at a very slow rate, maybe like add a 1kWh of charge in a sunny day. I'm talking without any battery in between, just straight from solar. However this EV...
