Honda eu3000is - Output Voltage 127V
I have a new Honda Inverter eu3000is generator and noticed that when we use it, the UPS we have connected to it doesn't like the honda's output voltage and won't switch off battery. I measured the ...

My VOM does measure frequency so it would be quick and easy for me to check before moving on to other possibilities.
Every Honda EU series genset owner knows (or should know if they read the owner's manual) that these gensets are wired with a floating neutral output, as detailed on Page 37 of the EU3000iS owner's manual ...
"System Ground
Honda portable generators have a system ground that connects the generator frame components to the ground terminals in the AC output receptacles. The system ground is not connected to the AC neutral wire. If the generator is tested with a receptacle tester, it will not show the same ground circuit condition as for a home receptacle."
Many devices such as an EMS will interpret this floating neutral as an open ground and refuse to pass voltage through to it's output - your UPS is likely doing the same. What is not likely at all is your EU3000iS varying frequency. By all means check it if you have the means but I'd bet if you G-N Bond the genset's output your UPS will be quite happy with the signal it's seeing.
