A limitation of the CS-100 is it can't accommodate the optional keypad payment mechanism. The CS-60 is the highest amp charging station Clipper Creek makes that will take the keypad. I don't know why. If a municipality or property owner needs to be able to charge for electricity, the CS-60 is the best they can do. That's why Fredericksburg ended up installing the CS-60 rather than the CS-100 that Tesla owners in Austin recommended. It's still a huge step forward from the overpriced and underpowered 30A Chargepoints
Here is a CS-100 with the optional keypad mechanism. Solar powered though so it's free.
