Parallel generators

I have a Predator 3500 and just got a new WEN 50a parallel setup. Since the hookups and specs are pretty similar anyone try and run two dissimilar units together?

If you experiment with tethering 2 different brands you do so at your own risk. If the result is smoke and fire the warranty won't cover it.

Parallel

Heck I'm not going to be the first, just checking if anyone else has tried.

NOT a good idea !!!!! You might be successful and get a 120 VAC output on the parallel kit output, you might get 240 VAC on the 120 plug on the parallel kit or you might get "smoke" from the wires on the parallel kit or "smoke" from one or both of the generators... Then again, you might get an "instant bonfire".... Keep in mind that once you "let the magic smoke out of any electrical equipment" it becomes an anchor....

Nearly every owner's manual for generators that can be connected to increase output stipulates "same brand/same model/compatible model"... I have not yet seen one that says, "We connect to the competition's generators"....

Parallel

Thanks, I spent over 30 years in electrical and electronic systems and parallel connections ARE NOT additive

But parallel cable kits "hooked up in series on two units that are not wired the same" (one for series connections and one for parallel connections) are (or can be) additive.... That's where the novice should "not go there" and someone with 30 years of electrical and electronic systems" should be aware of the pitfalls.... YMMV

The generator manufacturer(s) will tell you whether you can parallel with other brands or even if you can do it with the same brand but different sizes.

Typically you usually only see two generators of the same brand and similar size run together, but that’s just my observation. I run a single Generac Gp3000i and that operates my entire camper.

99.999999% chance of smoke and fire.....well, at least for a short time until you let ALL the smoke out. In other words....Don't Do it!

I think the quick and easy answer is read the manual. Let us know what it says. Bet it says parallel only to same model generator. There might be several reasons that is important.

Now, if you want to run L1 off one generator and L2 off the other, that should be fine. Get a 50A - dual 30A splitter (which separates L1 and L2). Control the load on each line to be within the generator that is plugged into that line, and you'll be fine. (So long as L1 and L2 never meet - if you don't have any 240V appliances (very rare), you're good)

If the neutral in the adapter is common to both L1 and L2, I believe you will have a problem still. I've never used one of the adapters you are talking about, but it seems that the neutral is going to be common to the plug.

Yep, you’re right. Scratch that idea. The neutral is going to compete and have all sorts of reaction. Would have to rewire your main panel to isolate L1 and L2 grounds, and use 2 shore power cables. Totally not worth it!
Thx for the backup!
