paralleling 6 kW single phase gensets

[junkhound]

Anyone accomplished this?

One has honda engine, the other a B&S. Have done paralleling with both gensets having GX Honda engine, but wondering if the governors on different brand single cyl gas engines will cause hunting or imbalance.

Might get around to trying it as just got a genset with the B&S engine, already have the Honda engine generators.

Parallel method used would be the simple single incandescent light bulb method and manual switch.

Is it even worth trying other than with inverter output type generators on that small of a unit?

Or is this more of a self amusement type of project?

The only ones I’ve seen, have been inverter type that don’t depend on generator rpm.

RPM is just a part of what needs to be done, they can be running same PRM and still have outputs not in phase with each other.

Yeah, and closed transition switches are not cheap!

That is the reason for the; ;incandescent bulb. Install across paralleling switch with switch open. Adjust RPM till close, light will slow to a 1 or 2 second bright dim cycle, close switch when bulb dark, Gensets in phase. learned that 60 years ago in generator class lab. using dc motor driven generators.

And then the presence of a common load will keep them in phase? If the load gets close to zero, can the generators lose phase with each other?

My thoughts as well, how do you assure they remain in phase? Seems they would tend to drift some without some sort of control that continuously monitors and makes adjustments as needed.

You might be able to make it work, but I bet that the dynamic response of each governor is different enough that one will soon be treating the other like a load and then, if you're lucky, you might still have one generator that still works.
