[RE-wrenches] Trace SW4024, 1998 vintage - Still OK for grid-tie?

[Jonathan Hill]

I used one made about that time in our home back in . It was the first grid-tie in the county and worked flawlessly for about ten years before we sold it. While it was approved at the time, I'm not sure if PG&E would approve it now, probably not. Might just do it!
