Definitely not. It was my first time using Sol Ultra, and I did not expect it to run for 12hr+ continuously. Previously with 5.5 I had to coax it to go for longer than a half hour, so I just started a run and forgot to check back in on it. I think I'm learning how to use it more effectively now, and I could see a scenario where that could actually be worthwhile, but it's a bit of a shot in the dark if you let it go that long uninterrupted.
