I need to install a charging point for our Model S in a rural location with no enclosed garage. What have others done in this scenario? We experience extreme outdoor temps. I am not sure if the HPWC is rated for outdoor use? We are in Canada and are considering this product, which would seem to deliver 72 continuous amps, less than the 80 from the HPWC: https://suncountryhighway.ca/wp-content/uploads/2012/06/SCH_CS_Brochure.pdf Any feedback welcome!
