Its a UPS.. APC Smart-UPS RT 1500 with an added 48v pack on the side of it.
Specs for this UPS indicate a +/- 5Hz auto sensing input frequency variance ... there's NO way your EU3000iS is outputting voltage with anywhere near this degree of frequency error, if any at all. This is a floating neutral / G-N bonding issue.
