I recently moved to a condo in Milwaukee with a 4 stall -detached garage wired for 110 service. Because the 110 line to each of the stalls is considered ‘common’ electricity, using this to charge my car is creating an issue. Having had a 220 line and Tesla charging unit in my previous home garage, ideally, I would like to have a 220 line to the garage that is metered to my electric service. However, the cost to do that was quoted as $5,000. In absence of that, I would like to use the 110 ‘common’ electricity and pay for the kWh used to charge my car. What is the best way to measure the amount of kWh I actually use? Is there a meter (like an appliance meter) that could be plugged into the 110 line to monitor my actual usage? What does Tesla recommend in situations like this? Thanks to all for their help!
