Exactly where did you discover this.......
In the ones that I have been into the generator is three phase AC variable frequency which is exactly what allows the generator to throttle up faster as more power is needed and reduce the throttle when less power is needed. This results in variable frequency at output of the generator, it varies from about 30 hz up to 400 hz, again three phase Then it is then rectified to DC. that is what appears ot the banana connectors......DC....The inverter in the generator takes this DC and inverts this into AC........The inverter in only one generator is used to provide the 60 hz. output
I have not torn into every inverter generator but the ones I have been into this is exactly how it was done.
I am way too curious on electricity to not dig into a variable speed generator that maintains constant 60 hz
Basic physics 3600 RPM 2 pole Generator ......60 hz...
Variable speed ......Variable frequency
It is not too hard to sync the inverters if both inverters are used but syncing two generators directly is not trivial, if one generator were to cough everything is knocked out of phase.....dead shorting each other out
Now you know how its done
Prove me wrong....
Thanks
@Tecnodave. I feel enlightened.
I think this helps explain why banana lead wires are such light gage.
Also, if I'm understanding correctly here, it seems that the inverter is best practice in joining (smoothing out) 2 devices, or inverters in this case.
I can't say I've seen very many parallel generator setups.
The theory of single inverter driving the output also is supported by fact that I'm able to directly connect to inverter control panel outlet, although it's only 30A. I wonder, however, if it should be the host inverter?
Taking this theory a step further, I wonder how the parallel wire kit is working with the NEMA 10-50R. I'd like to be connected at that point for the higher amp capacity, but not certain about the neutral path since that outlet is only 2 hot legs + 1 ground.
If only my case (#1 below) would have been designed something like #2 or #3 below from same company:
1 - 4500 (open frame) unit for some reason utilizes this OLD NEMA 10-50R (???)
2 - 7500W unit only uses banana leads while 50A outlet hooks directly from invertor (+++)
3 - 4500 unit parallel kit utilizes NEMA 14-50R, which includes NEUTRAL
Pose consumer dissonance :--(
My next step is to try hooking into my NEMA 10-50R with a ground fault tester.
I wonder if within my neutral topic is the topic of floating neutral (which I do have).
As I understand, if I have floating neutral, then the inverter needs to utilize my home panel ground system (Separately Derived System).
Thank you again !
