That's interesting. I hadn't considered the efficiency aspect. L2 would be a pain to install where I live, I'm thinking. It's a bungalow and the breaker box is about as far from the driveway in the basement as is humanly possible. So lots of wiring and drilling to bring the power out to where it's needed seems likely.
From what others are saying, I probably do not need L2 for my modest driving needs, but the efficiency aspect could imply it would eventually pay itself back in energy savings. But if I have essentially what amounts to the worst case scenario in terms of upfront installation cost, that could take a long time…
Off the top of my head, I think L1 is like 75% efficient and L2 is closer to 95%, so it's a pretty significant efficiency drop. For me though, it's a similarly difficult install, and I've just got so many other other projects on the go that I've just never made it a priority. Maybe one day if I ever get solar installed...
