Eric,<br>
A Trace 2548 with automatic generator start? I don't believe there ever was such a thing. I suspect that you're referring to either a SW4048 or SW5548. If so, your first step is to check the error codes, some of which are found in Menu Heading 2 (for generator-related
issues) and the rest in Heading 5. Any "Yes" message as you scroll through them is a good hint.

This inverter is at least 13 years in service, likely more. Sounds like a pre-GTI Y2K system. The units are remarkably robust and reliable, but it may well have a glitch in the firmware or voltage/frequency sensors. The extra inverter is your ace in the hole,
once you determine what the issue is.<br>
