New tandem sine wave generators

[2000 Damon]

With all this new technology coming out. IT's hard to keep up with it all. For instance. They have better generators and converters that put out better power sine wave production. This is supposed to reduce humming in fans and reduce the strain on a lot of appliances that don't run on pure sine wave voltage. Smaller generators put out less noise which is helpful when boondocking with neighbors or in a powerless campground. The smaller generators don't have the ability to run an AC unit but are capable when placed together IE 2 2000 watt pure sine wave generators. Honda, Yamaha and a couple of other companies have this technology on the market. The two like generators are placed together to allow 4000 watt continuous power. I was scheming and dreaming about buying 1 for battery recharge/trailer wide use except for A/C and then having the other available when it got real hot and I had to use the AC. But,I don't think it would help me with only having a 30 amp cable connection. to my trailer. I believe that both generators sync with each other to form like a 220 volt sine wave. One sine wave being 180 degrees out of phase with the other therefore creating the 220 volts. Is my thinking correct. Does anyone use these new sine wave generators to power a 30 amp circuit and get AC in their RV

Don't know how the technology works, but seems I have seen the tandem 2000s being used on a 30amp trailer.
And I think the 50amp circuits in RVs are 220, but with 2x110 legs for the extra amperage--not 220. Based on this statement, you probably don't want me re-wiring you house...

You were doing good up to this point.

Taking the points in reverse order

Two Honda, Yahama, or other parallelled generators (120 volt inverter kind) sync in phase to generate 120 volts, not 240 but 120.. It would be fair to compare them to two 12 volt batteries in parallel in this respect.

It is IN PHASE and it will work fine with your 30 amp trailer.

in fact the parallel cable has a standard 30 amp 120 volt outlet on it, Not sure which of two types it is.. Or let me look up a photo;

Found it, the Honda EU-2000i companion has a standard 30 amp 120 volt TWIST LOCK outlet, and they sell an adapter for a TT-30 plug.

But they work in phase so you get 4,000 watts (well around 3600 actually, note that is 30 amps) at 120 volts.

I appreciate the information. That helps me a lot in my choices for a generator. I couldn't imagine how they paralleled the two units to share the amperage draw on both units. Thanks again for your input
