So Irma blew by and tested my battery backup. Friday evening multiple transformers atop power poles outside my home exploded or burnt in such a way that made a loud electrical shorting noise and lit up the sky a blue-greenish color for a few seconds. And then everything went dark. Except my 3d printer..



Ya unfortunately this happened about 5 hours into the 13.6 hr print from the above post and the battery backup is good for ~ 2 hours. So I lost the print anyways but this counts as a test of my backup system and it kicked in and worked flawlessly and the printer never missed a beat. We got our power on today. Still no internet/cable and bad cell phone reception in areas. I am on the east coast of South Florida. In Broward County.
