I have had power company types tell me they are very careful about touching dead circuits because people have not isolated they gensets from the grid. They have said there is great joy when they reconnect the mains back onto the grid with the knowledge that someone genset has now leapt from the ground.
Backfeeding shore power is very dangerous. It damages equipment and is a risk to power company service personnel.
There might be some off the shelf devices that will feed from multiple sources, but I am not sure why you would want to do this. If the intent is to have some kind of auto transfer device, there are much better ways to do this.
I misspoke. PLEASE forget the initial comment about shore power. I was think in context of generating AC to a secondary source using shore power. I will not back feed. I will not back feed. I will not back feed. I will not back feed. X 100.

I sure my inverter, alone, will not start the air conditioner anyway.
If it could I may be able to do the same thing. I have an automatic transfer switch, which must be what you are talking about. No, they are not. The inverter senses no incoming ac and takes over.
Inverters have pretty big surge capabilities, as long as your batteries will handle it.
Yes, that's what I'm talking about.

Might work. I have to manually disconnect the converter when feeding off the inverter but I could manually reconnect when the AC is up and running.

Some inverters can sync up to outside power. They can let you start two air conditioners on a 30 amp power feed, for example. They can also sync up to any generator. But in this case it's the inverter with the smarts, not the other power source.

I have heard of folks paralling a Honda 1000 with a Honda 2000, start the non-2000 first is the rule.
However I will say this.. It is important that the wave form of both "Sources" be very very close to identical.. now with two Honda EU generators the same basic software controls the waveform in both, Only the power handling stages are different (and generating and the motor size) So a Honda 1,000, 2,000 or 3,000 will have the same WAVEFORM,.
I'd expect a Yahama 1200, 2400 or 3600 (EF-####i) to also be comopatable but I'd want to check it out.
If you are looking at say a Kilbasa Contractor Generator.. (Ok that's a made up brand) I'd not expect great success.

I routinely parallel my EU2000i with an EU3000is when tailgating on extremely hot September weekends. This lets me run both my 15k and 13.5k air conditioners. I have even parelleled two EU2000i's plus an EU3000is with a three way box which has a 50 amp receptacle.
My Honda dealer says it can't be done.

as youngster i was always intrigued by generators of all sorts. in high school i had enough knowledge of gennys to know about paralleling generators and syncing them.
once at a carnival i watched the electrician parallel small generators.( 4 cylinder wesconsins 20 kw at most). what he did is just switched the breaker on . 4 or 5 generators were there and connected to same bus through individual breakers..... i asked him how does he sync them... he told me he just hits the breaker and the generators sync.. if way out of phase they trip the breaker and he repetes clicking on breaker. it was hit or miss... seems he was just luckly i never seen a breaker switch off.
back then i read about a light bulb batween generators to get an idea of phase difference... when the light goes out then u are close to being in phase. then hit the breakers.
in the navy we had a syncrosope in 360 degrees increments... you just speeded up one generator till the meter went to zero degrees. you could see it clock around and when paralleled they stayed synced.
this was for information i would never recomend any of the above... i have seen lots of sparks in my days. my mom and dad would shout " what the h... are you doing " after the house power went out for some reason the master breaker triped.... ;-)
when u play in the sand .... you can get stuck

Quote:No the Honda cannot sync with shore power or external non-honda generator
perhaps not with anything except another Honda
doing this will very likely damage the Honda and perhaps other property or even you Why would the Honda eu-series generator not be able to sync with shore power? How does it know the difference between shore power and another eu generator? The only possible answer would be for it to look for the 50 kHz switching harmonic on the AC signal, but IMO too many unfriendly loads would defeat such detection and render the parallel capability unreliable.
Why would the Honda be damaged? It is tolerant of power from another eu generator being applied to its output when stopped or running. Why would shore power damage something when Honda power doesn't?
Here are 2 threads claiming successful parallel operation of Honda and Kipor inverter generators. One of the threads references another report of success but the link to that thread doesn't work.

Just thinking out loud - I wonder if a Grid Tie In Inverter designed to work with wind & solar installations would allow you to add from your batteries to the generator? They are designed to sync to the power lines, shut down if AC input is interrupted. Not cheap, but neither are standard inverters that can sync with another AC source...
