Predator 8750 / 9500 DIY Parallel Kit

- Here is how I went about building my parallel kit to run three generators all in parallel!! Not only that Ive also added the Predator 8750 into the mix and apparently it is actually parallel capable if wired with a Y cable and you are using a 9500 to sync with it. So you must first run the 8750 first as the master and then run the 9500 to synchronize to it.
Please note if you attempt to build this you are doing so at your own risk.

Predator generators are my most favorite
You should be using 10 guage wire. The 12 is rated for 20 amps. The 10 is rated for 30 amps. Each of those generators are good for 30 amps each leg. (yes, one of them is 29 amps and the other two are 31.
This video helped me consider other options for job site power management. Thank you!
Actually, those 9500 have a 50amp. Socket. You should be using #6 wire on 50amp circuits to obtain maximum load values. Under sizing wire reduces maximum amperage on your system. The first inverter gen is what is used to sync the other inverter gensets. So before starting the other two gens. Start and run for 30 seconds allow the motor to react and warm up before starting your other gensets. You can damage your inverter if it's unstable due to cold mornings of rough running engines. That why others use amp/voltage meters to monitor output voltage and regulation. If your first inverter gensets has a issue and you dobt catch it before starting your other gensets, damage can occur across each of the gensets.
I will never pull that much power. Yeah Im not buying that. Weve running them since this video and they been abused badly with no issues.
When running the gasifier two gensets = one running on gasoline. We dont have the equipment to pull the full 50 amps. The breakers will blow long before wiring will ever be an issue. There is a 30 amp main in the box it cant pull beyond that.
@@Thrive-Off-Grid I think your video is very informative, I just wouldn't want others to copy your design word for word using #12ga (20A) or a improper wire size That could cause damage. As your showing roughly 21KW of running amperage in your video there are people that will apply your design for uses that shouldn't. I heard your 'liability' statement, but most don't or don't care to follow standards. Thank u for your video and good luck with your endeavors.
@@36w3s.talbot4 Thats why I put a disclaimer. The point of the video is show how it works not the wireing. My set up is specific to our needs not someone "copying" Thats up to them to it right to meet there application.
I dont even know why I do these videos. I give up and will just stick to doing what we do.
@@36w3s.talbot4 Not to mention the 220 output on these generators are not 50 amp. They are 30 amp and if you get even close to that they will immediately fault out. The most two combined could put out is 50 amps. A short 12 ga cable is plenty capable of this.
Nice
If you are connecting to your house thru an interlock, you really should unbond the neutral and ground on the back of the panel(s). Simply remove the white wire from the grounding connector on the panel and insulate it.
Im not connected to an interlock or the utility. Im off grid.
@@Thrive-Off-Grid The primary panel in your electrical system is the only place your neutral and ground should be bonded... whether or not you are tied to the grid.
@@StanSimmons Its wired to the instructions that came with the inverter. So you are telling me every inveter in the world is is wired wrong? They al have four wire terminal blocks..
@@StanSimmons What the hell does it matter anyways. The com and ground are tied together somewhere anyways. They are typically terminated in a grounding block.
Ok yeah that is how it is wired into our inverter. Input block of our inverter is three wire input and four wire out to box. The live legs and the ground go to the input. But you should still wire this Y cable as four wire not everyone is going to wire into a panel. And I still dont get why it matters when the com and ground wires are bassically the same thing. They are both wired to ground terminal block inside the electrical box. I did wire our box it came pre wired.
Combining two of the 9,500 predators will that just higher the amp capacity and watts available? Will it still stay the same as of the 120v/240v available or will that go up as well? I have mixed 120v and 240v for what I need it for
It will just give you higher Amps/wattage.
For example instead of getting a huge diesel 15 thousand watts or more you can just get 2 smaller generators like this and run them in parallell for higher output power.
can you still put them in eco mode to save fuel? Awesome work!
Yes
Ok what happens if the master runs out of fuel or has an issue?
It won't matter. It will sync with the remaining 2.
I’m confused as to why you can’t do this with the 8750 if you have two of them?
Connecting both together into a junction box that has a 50 amp plug.
Why can you do this with the 9500s but not the 8750s?
Because they are not capable of syncronizing the two phase. The 9500 units have the ability to syncronize to each other or another 8750 if it is fired up first. The 9500 will then syncronize its phase to the 8750.
Scary that you plugged into the third gen after the other two were running
If he touched the prongs on that cable it would have sucked. He'd probably be OK, but it would really smart! ⚡
So, you did fire the 9500 up first and then the 8750 and it worked. Interesting.
The 9500 is the primary larger generator, the 8750 is the same sinewave as the 9500 so the 8750 would sync to the 9500. Not like two governor style gensets like one at 5KW and the other at 7KW. You would need to regulate the 5KW generators governor to manually sync with the 7KW genset, this is why syncing two governor style gensets isn't worth the money to sync together. Unless you want to sit there and play power source engineer while everyone else is inside the house living well. Just another thought pure sinewave inverters are used in many modern gensets. You can actually have a governor style genset (older Type) larger of course say 8kw and you can sync a smaller inverter style pure sinewave genset say 5kw to the older 7kw as that would act as primary. that would give you 12KW of standby power. All our solar systems are all sinewave and most are grid-tied. That means wherever in the US you plug in your inverter, it will match the power on the pole. Same way uising the old gentsets as long as its putting out stable power say at 50% load.
I'm confused. In older comments you stated the 8750 had to be used as the primary because the 9500 is the one with syncing capability. If what you're saying in this comment is true and the 9500 is primary and the 8750 is syncing to it because they have the same sine wave, then why couldn't 2 8750's be paralleled?
@toddbeedham4744 He said in the video, if I heard right, he did it both ways.
@@Bob-cx4ze I figured the 9500 would be the one to do the sync. OK. Good to know. It's been a while since I watched it.
The three wire version on display here is not a three wire. It is a two wire with ground. I am unable to see it closely, but it looks like it would be for a 220 volt welder where it does not need the common.
do you have to start the 8750 first for everything to sync properly
Yes the 9500 only has the ability to sync. The 8750 if the 9500 is running first will not bring power online. So it must started first. Dont waste money on these inverters. If you are using it for off grid. Get a normal generator and use the money you save and buy an off grid invertet with built in battery charger. Use it to clean up the power. If you are going off grid you have to buy it anyways so there is no point in buying the inverter generators. The off grid inverter dont care if the power is dirty or not.
@@Thrive-Off-Grid got the 8750 for 400.00(display model) and already had the 9500 just wanted to maximize the power output for welding and plasma cutting
Technically if you had 3 inverter generators with the parallel ports, couldn't you wire a 3-way the same way?
Yeah Ive done it you can add as many as you like. As long as your wiring can support the load.
Can two 8750 be parallel
No you must use the 8750 as a master with a 9500. The 9500 can sync to it; But the 8750 can not sync to the 9500 or another 8750.
@@Thrive-Off-Grid Ha! My question gets answered. Thank you!!!\
Wait a minute ... If the Predator 8750 can sync to a non-inverter governor style genset, then why wouldn't a 8750 sync to a second 8750?
@@gkorenek Seems like he said he's able to start the 9500 first/use it as primary in another comment so the 8750 is doing the syncing if started up later - I was looking at getting two 8750 and I'm pretty sure he's wrong but I haven't tested it.
Edit: where did you see one synced to a non inverter gen? another video?
@h82fail & @Thrive Energy Systems my questions are: Can 2 "8750" type inverter generators be paralleled (this by hand-wiring a "Y" parallel cable connecting to each generator's A/B/N 240v 30 amp output connector)? Can inverter generators that do not have "cable ready" parallel ports still be paralleled by a hand-wired "Y" cable" since it appears that inverter generators with front panel paralleling ports, the paralleling ports are wired off the generator's 240V A, B, and neutral sockets? What would be fantastic is if there were a bible or ruleset published that lists what is functional & allowable to parallel inverter generators especially for inverter generators with no front panel parallel ports and even include paralleling inverter with non-inverter generator.,
they mast eat fuel
