It shows OOS for me as well, but the page said to "Look below for substitutions". I didn't find any links, but they do list the same genny in a camo color. I clicked on the camo one and the price dropped to $299 in the cart, available for checkout but listed the color as blue, not camo. Who knows what you might end up with.

Thanks for the heads up.  Somehow my order went through after the reported out of stock.  If only I could parallel this with the Champion 2000 from last year's Home Depot sale.

I don't see why you couldn't.

They're both parallel-capable - and neither requires a special "interface" cable (besides the normal parallel cable).

As I have posted in this forum previously and Skibane noted, if they don't require a special connector or parallel device they should work in parallel fine.  I am using an A-iPower2000W/1600W with my Predator 3500 and run them together every month under load.  They Predator runs on NatGas, Propane or gasoline, and the A-iPower on gas.  It actually came with the parallel cables included and states on the box it will work with other brand gensets.  Look at the schematics for the brand parallel kit schematics to see how the wiring diagram illustrates the AC and parallel connections.  My opinion is that if you do not see some sort of "Black Box" in their kit, your cables will do the exact same thing as their wires.  YMMV, but this concept has been demonstrated several times on YouTube videos between many different brand gennys.

So my wife is wanting to buy a generator for her mom who lives in a remote Russian village that sometimes loses power. First off, it will be 220v. I assume since the voltage is doubled, an equivalent power rating will have half the wattage at 220. Does that sound right?

Also, I'm thinking we should get a dual fuel that can use propane. My logic is that this is better than it sitting with old gasoline in it and not working when she needs it. The Mom is 80 years old so she's not capable of doing much maintenance - it needs to be simple to operate.

Likewise, electric start seems like a necessity.

We don't expect to need it to run for exceptionally long periods of time. How long can I expect a moderate sized generator to run on a 20 or 40 pound bottle? The power load would be minimal - a small fridge, small microwave and a couple pumps (well & septic). And a couple light bulbs and a 46" LED TV. Not all operating at once, obviously.

Anything else I should consider? Any miscalculations?


ETA: This website has some decent looking models:

http://www.profpower.ru/category/kombinirovannye/

The electric start models are priced at 44800, 62290 and 81400.

A typical propane-fueled generator will consume right around 1 pound of propane, for every 1KW of power it is producing - i.e., if your load is 2KW, you'll be using around 2 pounds per hour.

Note that if your generator is a lot bigger than the load it's powering, fuel economy will suffer - So ideally, you don't want a huge generator spending a lot of time powering small loads.

There aren't any really small electric start generators.

Big generators are heavy. That'll affect shipping, and also her ability to move it around.

The voltage (and line frequency) varies by locale - In some regions, the line frequency is 50 Hz, rather than the more common 60 Hz. So, you'll want to make sure what you order matches what is used in that region.

Ditto for the power receptacles - Make sure she can plug her appliances into the generator without having to use adapters or splice on new plugs.

assume since the voltage is doubled, an equivalent power rating will have half the wattage at 220. Does that sound right?

No, the wattage stays the same, regardless of what voltage is being produced. For example, if a 120 volt generator is capable of producing 10 amps of current, that's 1200 watts. That same generator would only produce 5 amps at 240 volts - the same 1200 watts.

Thanks for the response! Wow, it uses more propane than I expected but still workable.

Thanks for setting me straight on the wattage!

I think we'd find a permanent place to locate the generator and have it wired into the house with a lockout panel. Labor is ridiculously cheap in Russia so it'll probably be a minor expense.

The generator i bought for us here in the US is an inverter model. Do they make dual fuel inverter generators?

Yes.

Here in the US, the vast majority of them are 120 volt only.

In the aftermarket, propane conversion kits are very popular for inverter models.

Not sure if you have to be a member to order.  I was already a member.  They show as out of stock now, but I have had one in my cart for a couple of days now, but the cart shows full price rather than the sale price.   I was able to order one earlier at sale price, and don't need a second one.  If I needed/wanted it I would probably call SC, confirm the generator was in stock, and then in light if the flyer showing the sale price and duration and try to get the sale price.

My honda 2000 ran for 26 hours straight during the power outage yesterday.  It used 2.2 gallons, give or take of gas.  I ran my fridge, and two power strips, with 2 tv's, 2 fans, my satellite receiver, gaming laptop and internet and modem.   It never left eco mode so it had wattage to spare.  Real world conditions in SE VA. It ran between 10 and 11 hours between topping off and I had a little less than a half gallon of a 2.5 gallon tank of gas left.  Great investment, the wife wants a whole house generator package though, who am I to say no.

Has probably been answered in this big thread somewhere, but will ask anyway. I just recently bought a Predator 2000 for a truck camper, no A/C, just LED lights, 2way gas/elec fridge, and a few outlets. The issue now is, that on Monday I'm picking up a new travel trailer with AC, microwave, gas/elec water heater and fridge, and a single slide, and your other typical TT electrical systems.

Should I just go ahead and pick up a 2nd Predator 2000 and parallel kit, or just go with a 3500 Predator? The original 2000 has been run about 15 minutes total after intial setup. I figure if I don't need to run the A.C., I should be fine with a single 2000. Can you hook up the 30amp parallel kit plug without having both units running, or would I have to just hook up to a normal 110 outlet on the genset?

If it was me, I'd stick with my current single Predator 2000 for a while, just to see if I really need any more power than I already have.

Should be able to use the parallel kit with just one generator. All it does is connect the AC output of two generators in parallel, so it doesn't have any way of knowing that you don't have a second generator connected to it.

Naturally, if all you want to do is adapt your 30 amp RV plug to a conventional 15 amp receptacle, there are a lot cheaper ways of doing it than with a parallel kit.

LOL, had one of those adapter plugs as early as this morning. Remembered I had set it on top of my tire after I had already driven 100 miles from the campground I was at the last 4 days

Really wish I had the new travel trailer with AC, was very hot in NE Wyoming the last few days. Pretty sure a single 2000 won't run the AC.

A 15k BTU A/C running on high would need at least 1800 watts to be safe

Looking for some guidance on using my Champion 2000 inverter generator as a light weight substitute for my 17500 Generac.  I have a transfer switch to isolate from outside service when I run the Generac.  I’m looking to take the Generac offline and use the Champion as a night time generator running a few lights, a fan and an O2 concentrator.  If I use thIs adaptor to tie into my 50 amp power cord, and open all circuit breakers but the one or two powering the 120 volt outlets in the bedroom, are there any issues I need to be concerned about?

Thank you for any input.

Does that particular adapter have both legs of the 240 volt receptacle internally connected to the 120 volt plug, or just one of them?

If it's just one, only half of your residential circuit breakers will receive power.

Look for the cord and look at sellers items.  They make anything in any combination you need.  You can even contact them I believe for a custom one.

I picked up the big brother this week - so far I've only broke it in but I like it. Like you I have a 240 well and 30 amp plug (so on paper can carry max of ~7500 watts). Reason I chose it over the smaller version: electric start (and pull back-up), 7000 running but at 25% you're running 1750 which I'm good with for our needs, and finally the bigger one consumes .40 gals/hour @ 25% load while the smaller is .35 gals/hour @25% load. Figured I'd rather run at 25% on the big one than 50% on the smaller more often. And the $$ wasn't that much more.

It's *slightly* less loud than a regular genny. Don't expect typical inverter noise levels - for that you need to drop 4K on the Honda.

@brcarls:

I finally do now. Running off genny since yesterday evening. It's like the power never went off can use just about everything without flipping breaker switches. The Champion has an "eco-mode" that seems to keep up with the power demand and steps up the motor without anything dimming - can be turned off. Had almost no draw last night and a single tank lasted just under 11 hours. Ran geothermal this morning (haven't tried that in conjunction with well yet) and genny got louder and drank a lot faster but everything worked. I'm quite impressed.

Are two generators with a junction box better than one separate generator?
It seems like probably as you can then take one when you don't need as big of generator. Or am I missing something?

2x the maintenance, 2x the noise, a lot of extra "stuff" when it comes to junction boxes and extended run tanks.  Overall, a lot of extra hassle IMO

My dad had 2ea Honda 2000 with parallel cables, extra fuel tank, etc.  It took up more storage space, was louder and much bigger effort to setup than my 1ea Champion 2800 (3400 wasn't out at the time).

I used that Champion hard for years,  eventually made a extended run tank for it and it could go for 40hrs.    We ended up buying a larger RV and the little Champion 2800 couldn't handle the 15k BTU A/C reliably ... much less any other loads.   A 3400-3500w generator would have been fine for just normal RV usage,  BUT we use our trailer mostly at the race track and run tire warmers as well which draw 2400w for the two sets

So I ended up buying a Cummins/Onan 5500w that puts out 120/240.  I have one 23a leg wired dedicated for the A/C unit and the other 23a leg for everything else.   I also have the 2 legs wired to a 240v 30a outlet so I can plug in 240v equipment if needed OR plug into my house for backup!

Yes,  yes it does... it's logarithmic.  Also, please note I sad "2x the noise"  not "twice as loud"

I have have two Honda 2000s. When I ran them after irma I could not hear if one quit. The difference if any is not discernable.

I have run 2 Honda 2000's side by side to a single Honda 3500.  The 2 -2000s are significantly louder than the single 3500.    I have also run 2-2000s vs 1-2000 ... two are louder.   Just like kids,  2 kids are louder than one

Do your two kids have certified db data sheets?

If the man wants two units he should buy two units.

If you add two sounds of equal dB level you just add 3. For instance 50 dB + 50 dB is 53 dB.

To add sound sources of decibel level a and b you use this formula:

   Total dB = 10*log(10^(a/10) + 10^(b/10))

Total dB will always be a+3 when a=b.
So the generator I am looking at is rated at 56 DB. So it would be 59 decibels which is negligible.

2x the flexibility
2x the ability to tailor production (and therefore fuel consumption) to the load.
2x the redundant backup in case one unit fails.
2x the ability to take one unit to another area on the property or loan it out.
2x the ability to change the oil on one unit while the other remains operating.
2x the ability to cannibalize one unit to keep the other running.

That is where my mind went. 2X maintenance isn't a big deal for a generator, very low cost. I will be buying some property and would rather not haul a large generator around to power a smaller tool that doesn't need something that big.

Does it matter?  You would ignore it and say that you don't like kids.  Just like you ignored how logarithmic addition works

Agreed.  But he asked if 2 was better than 1.   I don't think it is... you do.

Depends.  Lets say you want to run an RV A/C  a single 2000w unit will not work reliably.  So it takes 2-2000s.  If one goes down,  you can't run your A/C even though you have one still running.
