To elaborate: this would work only if the two generators could somehow be made to run at exactly the same speed and be locked in phase (actually, 180 out of phase). With your typical generators, this is impossible without extensive modifications. Much better off to get a 240V generator.TonyWilliams said:jpokoraw1 said:Would this work to link two generators together to build a 240v outlet? http://www.quick220.com/" onclick="window.open(this.href);return false;

No.
Modified sine wave inverters = power pulse generators. These inverters output +170V for a time, 0V for a time, -170V for a time (same time as +170V), then 0V again. This repeats at 60Hz (or 50Hz, depending on your country).garygid said:The wall (Grid-Powered) outlets usually have pretty good sine wave waveshapes, and only infrequent spikes.
A "modified sinewave" inverter (or generator) actually outputs a 2-step square wave, with the waveshape looking like a 2-layer wedding cake up, and the same (but inverted) down. So, it essentially has 8 substantial "spikes" each cycle, or 480 "spikes" per second.
Some electronics do NOT like that type of input, while some other devices do not care.
So, the "modified sine-wave" is NOT a sine-wave, but just advertising, similar to a "Range Extended EV".

Can someone please tell me what is supposed that two 100K resistors do? how do they "trick" the EVSE?QueenBee said:JeffL said:The generator needed neutral and ground joining to run the Leaf charger, but I checked with the manufacturer and this is OK with this model, and is quite usual in the UK (TNE rather than PME for those who care) when using generators.
Just to clarify that I think Ingineer has made it clear that this bonding between neutral and ground should be done with a 1/2 watt 100k ohm resistor and a second one from the hot leg to ground.
smkettner said:^^^^ As far as I know your neutral and ground should be bonded (connected) at the main breaker panel.
Should not be relying on any "earth" ground to connect ground and neutral.
The resistor is to trick the evse on a generator without the neutral/ground bond as it has a floating ground. Should not apply at home.
Hmmm, I wounder how did you found I am from Portugal ;-)QueenBee said:From what I read in Portugual their ground isn't floating but it is connected to the buildings grounding electrodes only. They don't bond ground and neutral at the panel like we do in the US. I presume this is the issue.

Your are correct, ground isn't floating but it is connected to the buildings grounding electrodes only, here in Portugal.
