How do you adjust voltage output on new Generac XG8000E generator? Current output 92 volts. Suspect rpm's need to be increased.

SOURCE: I disassembled my EM650 Generator and to clean out

Most generators (except the latest inverter generators)
produce power directly dependent on RPM's.
The governor adjustment is critical.
This usually is in the form of an adjuster that through a spring, applies a preload to the governor arm.
The governor arm is attached to a shaft that disappears into the motor. Inside there is usually a set of weights that when spun faster will attempt to slow the motor and when spinning too slowly will attempt to increase revs. The adjustment you need to make is to the preload spring.
They are very sensitive to the motor being in good tune so do the air cleaner, spark plug etc before trying to get it right. Under voltage can do more damage than over voltage so take your time and get it to a good steady correct voltage with your usual expected load on it. A safety trip out box gives you a way to test voltage with a load on & some protection.
Work safe

SOURCE: Guardian generac 10kw model 5502 does not output correct voltage

the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it

Sounds like Generator mode switch should be "ON".

SOURCE: how to adjust voltage output from generator ?

As long as your appliances are working properly I wouldn't worry. A 10V drop from the norm is not that crazy and certainly not abnormal. If it drops down to 205 or 200 then I would worry. I'm not familiar with the internal components of a home generator but I would imagine they are not as precise as the machines the power companies use. And when you look at it from a phase point of view its even less of an issue. There are 110-120V per single phase and 220-240V double phase. So on each phase your only dropping 5V out of that range. And as far as the needle jumping, again not very precise, and it will probably move even more while its generating. If the voltage does happen to drop more check for a loose neutral wire, that will often cause crazy voltages, but so far I see nothing to worry about.

Testimonial: "Thanks.... :)"

The voltage regulator board on this unit is notorious for failing. If you are handy, you can replace it yourself with basic tools and a voltmeter to set the output. The part is about 200 dollars. Good luck
