Of course, and it works well too. When I moved houses from solar wind to solar + mains I switched my e450 off, this is only 4 years ago; it works fine. I love that machine ; it looks the part and it's indestructible. My company in the early 2000s was running on sparcstation 5s, a lot of them (they were giving them away by that time); I have them all in my garage and they all work still.
