Well shot video. I understand what to do and how to do it. Should I place WHITE colored tape on the end of the NEW two each neutral wires I added. My fear is because they are black in color just like the other wire is black a second person may reverse the two black wires. If I placed white tape at the end of my two new wires that fear may be lowered. Red to Red, Black to Black, White to White.😀

Just used the white ones when you making it I had two extra black ones that’s the only reason I use those but I could just paint it white😅

[@alfievance]

Hello Gavin...question for you concerning the two preditor 9500 watt generators. Are the two Hots, Neutrals, and ground terminals coming from the 240 VAC 30 Amp 4 pole plug (far right location) .... are these terminals common (meaning each has continuity with the respective other terminal) with the opposing Red Hot, Black Hot, White Neutral, and Ground screw terminals associated with the ("parallel port terminals")? If this is the case... It seems a cleaner design would be to incorporate some 4 conductor SOO 10 Guage cable using a NEMA L14-30p 4-wire locking plug. That way it would be 30 AMP rated and cleanly tie the two generators together providing a single twist lock plug coming from each generator into the Duromax xp9000ih Parallel Kit box. My worry is there might be some unique circuitries in the parallel port terminal area that would get ignored and require only the method you have demonstrated. Thanks for your answer in advance.

[@GeneratorReviews]

We would have to chat about this. I can’t give you a straightforward answer.

[@alfievance]

@@GeneratorReviews I have since measured the continuity on the parallel ports and the L14-30 plug receptacle. The two Hots show continuity as long as the 30 AMP two pole breaker is closed. This could be a problem if the breaker were to open during operation. I now believe the PowerHorse cable should be connected in parallel between the two generators BUT not run the power through these same cables. This way the Inverters remain synchronized in frequency and voltage but we are NOT pushing the 30 amp loads through the parallel port banana connectors. I plan to run the loads through the 14-30 receptacles on each generator respectively since they all measure to have continuity. This allows the two invertors to always remain synced and it allows the loads to each have their own 2 pole 30 amp breaker for protection. This is how the PowerHorse 7500 watt generator company suggest doing it and I agree.

[@willyfromthehillies]

[@davidnachbaur6805]

[@paulgandy5259]

Question … most people are using there generators to run their homes in the event of an outage. Where is the benefit in running two generators in parallel if a 50A inlet can only handle around 12,500 watts total, which is less than what those two inverters combined would produce? Not a criticism but I’m trying to learn the process.

[@GeneratorReviews]

Great question. Let’s say you have a 5 ton AC and you try to start a second large load the second generator would cover the additional surge required to start the load and not trip your 5 ton AC.
Two generators also help with your generator running at 100%. It’s much better to have two Generator running at 50% for fuel efficiency, longevity and redundancy.

[@chrisxavier3782]

Great video

[@jrumlr]

awesome man

[@Gizmos1044]

It's very disturbing that Duromax doesn't connect the neutral in their parallel kit. It does specifically say 240V 30A, and 240V 50A above the receptacles, indicating it's not intended for 120/240V use, but their receptacles are 4 prong, and users will definitely be connecting their houses and/or RVs to it. This leaves your neutral floating and results in unpredictable voltages from line to neutral. One possible way it will work is if neutral is bonded to ground in the house or RV panel as well as in the generator. In this case they are using the ground as neutral, but this is definitely a code violation and a wide open for legal liability. RVs should typically not be bonded, hence why they use a 4-wire cord.
Note: you did not connect your neutral to the 30A receptacle, and I strongly suggest you do.

[@GeneratorReviews]

Thanks Gizmos
You’re right I need to connect to the 30amp as well
All great points 👍🏾

[@Kingkoopa00]

Do not connect neutral to the 30A outlet.
Duromax messed up SO much with this thing.
First, with the no neutral on the Plug *designed to have a neutral*. You try plugging anything that requires a 14-50 plug into that it will flat out not work. Things like dryers, ovens, and what not use both the 240V for the high power stuff, and 120V for circuitry. Not having a neutral will make the stuff waiting for 120V flat out not work at all. If they wanted to not have a neutral, they shouldn't have put a 14-50 outlet there, and instead put a 6-50 outlet.
Second, Two wires per screw lug in MANY locations on this device. You are really only supposed to have one wire per lug on outlets. Proper way to do it is with a proper wire splice with multiple pigtails. (They may have gotten away with it using crimp on terminals, but I don't really know if that changes the rule of one wire per terminal)
Third, the wiring diagram in the manual for this device is also completely wrong. It has both HOTS on the 14-50 outlet wired to each other. Then, it has the OTHER hot wire connected to the neutral. Finally, it has the 30A outlet labeled as an L5-30. L5 is ONLY 120V. It has one hot, one neutral, and one ground. It cannot be used for 240V. I don't know what the actual plug on the parallel kit is (it's labeled on the face of the plug itself), but since it's labeled on the front as 240V/30A, it HAS to be an L6-30. The L6-30 outlet only has two hots and a ground. NO NEUTRAL. So make sure you do not hook the neutral up to it. The way you did the neutrals on the 14-50 outlet is fine (even though those outlets are usually only designed for one wire per spot, as stated above.) At least you now have a proper neutral running to each generator, and to the neutral on the 14-50 outlet.
I don't know how the hell this thing made it past safety regulators with how it's wired.

[@smokeab4613]

​@@Kingkoopa00I have many questions for you. On a project I'm working on

[@kobradovits]

I think this is just another Chinese misunderstanding. In some countries they use just the red and black for a 220v appliances. They don't split the legs with a neutral. Looks like they offer that form of 220 with a ground and don't understand that alot if not most American 220v aplliances use seperate legs(Most AC's and some ranges). Now the funny part of all of this to me is the fact that Harbor Freight 1. Went back to Red Black Ground only connections. 2. They advertise their Par-Kit as for 50a@120v only.
I wonder how bad it would be to just link up two 30a connections to a 50a recepticle? From what I can tell the "Parallel" plugs are just another connection but without a breaker.

[@davidmarconi528]

​@@Kingkoopa00 thanks for your statement here You're really cleared a lot of things up and confirmed what I was suspecting. I've been reading all over the place to try and sort out how to make my own box to parallel two 240 volt generators but AI power did not make a parallel kit with a neutral either. Very similar to duromax. Frustrating unsafe and misleading when trying to use two units. I was thinking of doing what Gavin did here but since my generator does not have a neutral port I'm thinking I will have to use one of the outlets and wire up a plug with only a neutral. Does that logic sound correct to you?

[@smokeab4613]

Wouldn't you wanna unbound the neutral from the frame? If running as back up power to house. I'm learning thx

Tried to fit one of the wires from the DuroMax kit in the neutral socket and it doesn't seem to fit (maybe it's a safety thing so you cant plug it in wrong?) -Besides that, the PowerHorse wire is 12 awg, the DuroMax uses 10 awg

Because you want each generator to have it own path versus overloading one wire if one wire breaks, you still have the other one.

You should have grounding rods attached to those generators as per the manufacturer's instructions, otherwise nothing you connect to it will have a real ground which isn't safe especially if you're going to be hooking it up to a home transfer switch or expensive RV.
And before anyone says anything it's on page 8 in the generators owners manual where it states "To ground the Generator, connect a #4 AWG grounding wire (not included) from the Grounding Terminal on the Control Panel to a grounding rod
(not included). The grounding rod must be an earth-driven copper or brass rod (electrode) which can adequately ground the Generator". Manuals for previous versions of their generators suggest a ⅝ inch diameter grounding rod no less than 36 inches in length which seems to be the standard for generators.
