I have the standard ATS switch on the solar installation. My network gear and computers don't like the switchover time when the grid fails.
Now I have a couple of very basic UPS's to prevent reboots/crashes of those pieces when the grid fails. I only need UPS power for less than a second or two.
As I'm always interested in improvement, I'm wondering if there are ATS switches that are fast enough to prevent the reboots without requiring UPS protection for computers and network gear.
