Electrical Engineering - Parallel Generators


Expert: cleggsan - 9/15/2009

Question
Hi
I have two of the Honda generators EU200i with manufacturers recommended parallel kit reliance HP K2011.
To run my house during an outage, I desire to come out of the 30A plug on the reliance unit, then split the circuit into (2)-15A plugs.
I do this with the intent of plugging one plug into a 15A protected circuit that feeds to one side of my main house breaker buss. The other plug would be fed into a separate 15A protected circuit, feeding to the other side of the buss.

I experimented with this setup using a single generator to each side of the breaker buss, but I have been reluctant to run the two parallel generators in this manner. I don't understand what would happen to my 220 circuits in the house. The power from the reliance is not synchronized, is it? It looks just like a cheap breaker box. If it is not synchronized, am I heading for trouble? AM I ok as long as I don't run 220 appliances?
Thanks  

Answer
The combining kit has a synchronizing link between the two generators.  These Honda units are inverter based and they can easily be synched; that is why the paralleling concept works.  For conventional generators that are based on conventional generators it is dangerous to parallel them.

The output of the Honda's are not synchronized with the utility company, so it would be dangerous to run back power while connected to the outside world.

As to the rest of your question I recommend you contact with an expert who has had direct experience with running the Hondas in parallel operation.

Best wishes,
C
