Worth knowing: Many OEM level 1 chargers will work at level 2 (up to 208V/240V, 8-12A). Do your research, your milage may vary.
The price difference of charging at home verses paid chargers very quickly covers the cost of a charger, even without the tax credit.
Go for the highest amperage level 2 charger you can reasonably install. For example, even if the car is limited to 7.8kW, the 9.6kW chargers are only a little more expensive and may work out better for your next EV.
If anyone knows of a level 1 or level 2 charger that can output 6A (lowest in the spec) let me know. That would be convenient for solar.
I have the Emporia L2 charger and it's been working perfectly charging at 48A 11.4kW.
I just checked the settings in the app and you can manually dial it all the way down to 6A.
It also has automated rates that integrate with load sensors, but I haven't explored that yet since I'm on flat ToU and full NEM.

The oem L1 charger that came with my ioniq 5 can be dialed back to 6amps.
6 amps? Would that even be worth it?
When my bolt trickle charger drops to 8 amps I get quite annoyed!
I just plugged some numbers into this website. Assuming a Bolt at 20% to 80%, it would take 3 days to charge. As opposed to about 2 with 8 amps.
But if you’re charging exclusively with solar, and assuming 12 hours of sunlight, it would take 6 days.
I think having a way to charge the car off solar panels is going go become part of everyone's normal emergency kit in the future.
They keep getting cheaper, portable battery generators are getting cheaper and people are buying them to take camping or keep a fridge going for a short period. It's like the step between now, and everyone having a grid connected solar/home battery.
But with a couple portable solar panels and a portable battery, you'll be able to slowly power your car in an emergency. Might be slow, but it's better than no gas at all.
