So, I pulled the trigger (thanks everyone for the help in making an informed purchase), not time to prep the garage.
I ended ordering a 85kWh battery and the HPWC and dual chargers.
I mostly work from home, but have to drive Sacramento to San Jose (220 miles round trip) about once a week, but sometimes more often and on consecutive days.
I have a 4.9kW solar system on my roof (thank you Solar City) with the idea that I would use that for daytime charging of my Model S. At the same time, the local utility offers a dedicated ToU meter with a special rate for EVs thats about $0.03kWh cheaper off-peak.
My concern is for days when I have back-to-back trips, I want to minimize my costs for charging off the grid. I am wondering if it makes sense to have my utility add the dedicated ToU feed and have a switchbox or the like installed so I can flip over to the cheaper ToU power at night.
Any thoughts on this? I kinda think this might be over-complicated to save $0.03 cents/hr.
