We have a detached two car garage/carriage house with 100 amp service. I had an electrician out 2.5 years ago to get a quote for a Nema 14-50 before my husband took delivery of his S only to learn that we don't have enough available amps out there. Options were to either run a new circuit to the carriage house to update the service from 100 to 150 amps or disconnect the existing 60 amp furnace circuit, run a gas line to the carriage house, and replace the existing electric furnace with a gas furnace, thus freeing up the 50 amps needed. Both options were $$$$ so we elected to do neither, and my husband has been charging his S by plugging it into an existing dryer outlet in the garage and using an EV charger in his parking garage at work once a week. He is a very low mileage driver (1 mile commute!) so this has worked well for him. I am taking delivery of my X hopefully by the end of the month. We are in the planning stages for a garage/carriage house renovation to begin this winter after our carriage house tenant moves out. Right now our 2 car garage is really only a usable one car garage because the existing furnace and hot water heater on the left side of the garage don't allow an S or an X to pull all the way in. In the short term I plan to park my new X where I always park, which is in the parking pad in front of our home (uncovered, no charger). When hubby is at work and I am home during the day, I can pull into the right side of the garage and charge. He can park and charge there at night, as he currently does. In a pinch (don't tell Elon), I can run over to the supercharger that is about 1.5 miles from my home. What should we plan to do once we renovate the garage/carriage house? We will definitely be relocating the furnace and hot water heater up to the carriage house floor so we can park in both sides of the garage. Should we upgrade the electrical service and add a 14-50? Or a HPWC? (The other slightly cheaper option is to run gas service out there, thus freeing up the extra amps needed for a 14-50.). We have looked into solar panels but were told there is too much tree cover. We have a solar panel company coming out next week to confirm. What if one of our kids gets a Model 3 down the road? Any thoughts on long-term charging plans with multiple Teslas? All of this is slightly comical if you could see the very rough alleyway that we drive on to access the carriage house and the many stairs between the carriage house and our main home. Picture main house right at the street and carriage house at bottom of gully way below. I will continue to park in the parking pad unless I need to charge! Thanks in advance.
