Thought I would start a thread about the cost and logistics of installing your home charger solution. I'll start it by saying that I am installing a HPWC and a 14-50 outlet in my garage in 2 weeks. The 14-50 is a backup (belt & suspenders) in case the HPWC fails (not common but has been reported). I ordered my MX with the 72A charger. I have 200A service and my electrician did a load calculation and advised me that there is no problem installing the 100A breaker for the HPWC and the 50A for the 14-50. The run from the main panel to the HPWC and outlet is short - about 20 ft. I purchased the HPWC at my local Tesla store (Paramus) for $750. My electrician, who is a friend, has quoted me about $500 complete to run the conduit and install the breakers, charger and outlet.
