Yes Clipper Creek was most helpful and they sent me a programming unit. You need to open the box but they give clear instrutions. You just download the program you want. They have a different firmware version for each possible maximum amp setting. So if anyone needs a high speed charge in NE Tennessee just let me know.
Nice work. So I guess you can control from your car how much you want to draw now.
Does anyone know if Tesla is making their own HPC for the Model S or is that also ClipperCreek? I'd assume they are making it themselves to make more profit.
This is a Tesla HPC so I think Tesla subs the manufacturing to Clipper Creek. Since I only installed a 70 amp breaker I limited the unit to a Max of 64 amps. I know that t is above the recommended limit but I set the standard charge on the Roadster to 48 amps. This is comfortably under the limit. It will be rare I need or use the higher rate at home.
I think most people will also set the power lower than 72A, most of the time.. You will just have the capability if you need it occasionally... You will need to put it on a 90A or 100A breaker if you want the 75A capability, and wire it with large gauge wire (like #3 or #4 for the 2 hots, the ground can be #8)
There is also the WHPC, that's $1,200. Thats their Wall Mounted High Power EVSE (it shouldn't even be called a charger, it's just a fancy interface/protection device)
Together they are $2,700
Go check it out on your configure page.
