2 generators simultaneously for backup power
Here is a question i thought some of you might have a thought toward. I am planning on getting the champion inverter gennie for some general use. However I was thinking about some backup power for m...

Pre-proven disaster ready to pounce. Paralleling generators is an artform. The generators must be similar. Same type of voltage regulator. Neutrals connected. An incandescent lamp connected parallel with both L1 Phases. Speed MUST BE EXACT between the two prime movers. 60 Hz right on the nose.
When the generators are out of phase the light bulb will light up. Slowly but surely the light bulb will dim then go out. Count the seconds the light is out. Wait for another lighting of the bulb and when it goes out again count to one half the total time the lamp remained off the first time.
If the lamp stayed off 6-seconds the first time count to three then trip the main switch to on. The generators are paralleled. Instrumentation is mandatory. Two ammeters are mandatory.
Fun & Games will begin if the genertors are not identical in both capacity and govenor response. One willead the other will lag. One or both will start surging.
You don't really want to get too deep into all this do you?
Dual voltage generators NEVER offer a 120vac output anywhere near the advertised wattage of the machine. If you operate dual voltage machine for max 120 volt output get a transformer.
