    Doesn't say if it has pure sine wave or not I haven't found any other reviews so beware if your thinking of using this on sensitive appliances laptops, tablets even microwave as it may cause problems or worse . Fyi for the best possible you need pure sine wave inverters .

    • +9

      This site https://www.mygenerator.com.au/briggs-stratton-2400w-inverte…

      I think that's what power smart is?

      • +4

        Your right my mistake after looking in the specs I found it .You'd think they would headline that as its a important feature these days .

    • +10

      This isn't a UPS, which has to take stored power and build the AC signal. As a generator it's going to produce (pure sine) AC, so that's not a product spec to search for. If anything, the additional DC outlets would be more concerning.

      The brand website does call out being ok for sensitive electronics though.

      • +6

        It likely isn't a ac generator but a DC gen with inverter. The fact it lists inverter in the specs suggests this. They are often done this way as you can be more efficient and hold a steady frequencyuch easier as the digital response time is much quicker.

        Laptop powersupplys are much better so even pwm inverter will be fine, the filter caps will take it out.

        • -1

          You mean AC gen with inverter, not DC gen with inverter. If it was converting DC to DC that's called a "DC to DC converter."

          • @[Deactivated]: No, they mean DC generator with inverter to convert to AC. This will produce a pseudo sine wave as it's done with power electronics as compared to an AC generator that will produce a clean sine wave.

            • +2

              @anthonaut: They may mean that but as someone pointed out a couple of posts down they're wrong. It's not a DC generator, it's an AC generator with AC inverter for power stabilization. It's much easier and cheaper to produce AC in the first step because lighter/thinner/cheaper copper motor windings are used, plus the expense of the circuitry to turn DC into a pure 240V sine wave is prohibitive. A glance comparing the price of 12V DC to 240V AC modified sine wave inverters someplace like Jaycar, compared to their 12V DC to 240V AC pure sine wave inverters, demonstrates a DC motor to an AC sine wave would become so expensive to make no-one would buy them.

      • +1

        If its not generating DC what is it inverting to output AC?

      • +9

        You're right that they do produce a pure sine wave, but the problem is that the frequency and voltage is unstable because the little petrol engine has poor speed control in general, and especially with varying loads.

        The method used to keep the output frequency/voltage stable is to convert the generated AC into DC, then invert the DC back to AC using precision MOSFET's in parallel with a big capacitor which produces a sine wave that has both a stable voltage and frequency:

        https://www.anker.com/blogs/home-power-backup/what-is-an-inv…

        As an aside, this is also how variable speed drives work, just with the MOSFET operation having variable instead of fixed intervals.

        The downside is that you actually don't end up with a pure sine wave (even if advertised as such) as the output AC is now actually DC chopped up by the MOSFET's, but it is far preferable to the unstable AC naturally produced by the generator.

        • +2

          Interesting, thank you for the explanation. Does this result in a less stable/clean output than a say a standalone 12V or 48V DC -> 240v AC inverter running off a battery, or do they both operate/invert with the same circuit arrangement?

          • +3

            @howcan: You're welcome! You're right in saying they both have the same circuit arrangement except the battery powered inverter is obviously missing the rectifier part that the generator has because its already starting off with a DC source (battery).

            Assuming you have a quality inverter they should be about the same.

    • Yeah as mentioned, generating electricity from rotary motion generates a sine wave by default. There isn't electronics trying to replicate a sine wave from DC like in UPS or power inverter.

    • +2

      Most electronics don't give two shits about input power quality. 99% rectify and cut it up themselves anyway internally. I've used 120VDC in power outages to run my laptop power supply no fuss.

      Pure sine wave is more relevant for analogue-style equipment (eg. Induction motors and the like, in fridges). I can't actually think of many things most people would have in the house that cares about good power quality (because it's mostly uncaring electronics XD)

      • Pure sine wave is up to 30% more efficient than modified sine wave inverters.

  • How long it will run in full capacity with 3.8L fuel ?

      • +1

        doubt it's a linear relationship - there will be heat loss etc associated with turning it on and probably just stay the same even with the increase in load. Not sure how much, though. Fun fact, by my calculation this thing only needs to be able to run for 3 hours at full load to give an EV more range than a ICE car with the same amount of petrol.

        • +1

          Fun fact, by my calculation this thing only needs to be able to run for 3 hours at full load to give an EV more range than a ICE car with the same amount of petrol.

          3.8L of petrol can move a Corolla Hybrid 100km. You'd be lucky to get 15% efficiency out of these rudimentary engines which would only be about 5kWh from 3.8L of petrol. 5kWh would only take you 35km in an average EV. Subtract charging losses from that as well.

          I haven't run the numbers, but this doesn't sound right. This would require this generator motor to be drastically more efficient than the vehicle's motor under comparison - which seems unlikely.

    • +26

      Few things you need to know… Don't let fuel sit inside these for too long as it goes bad… 3 months tops. Run them dry when storing… I pull spark plug and put teaspoon of motor oil, replace spark plug and turn over 3 or 4 times when I'm winter storing. It will be harder to start when you bring it out of storage.

      • +4

        sweet, thanks mate.
        i would have done none of those things for sure, if you didn't give me those hot tips.

      • +12

        This - Run it in under load so its ready for when you need it.

        Fill with oil (they come without oil) - Ideally run a non-friction modified/mineral/"running in" oil - Warm it up for a few minutes - Put load on it - Change oil at 30min of use. Repeat process 2-3x.

        A lot of metal will come out, this is normal.

        Complete the storage procedure quoted above.

      • Have also heard that when you store (small engines generally) pull starter cord to locate eng on comp stoke so all valves are closed, to reduce valve face seat deterioration.

        • +2

          Should have read reviews first. Watch for leaking oil. Many of these soon start leaking from the shaft seal. You might be able to buy a better quality seal. Change it fast before oil flings around and gets on everything, eating plastic, dissolving the pull cord, eating off stickers and paint, etc. You won't see it for a while either because it will be dripping inside behind the pull cord cage.

          Also all those Chinese brands are crap really. People think they're saving money by not buying a Honda or Yamaha, but the Chinese crap uses more oil due to wider engine tolerances, so the ongoing cost of oil quickly eats up any initial saving. They're also noisier (some caravan parks for example won't even allow you to start a generator if it's not a Honda), and they're poorly machined meaning they wind up with shaved metal in the sump, which recirculates around the engine scoring the piston/rings/bore making it worse.

          Oh and out of Yamaha & Honda I'd forget Yamaha. Yamaha ONLY supplies parts to authorized repairers and there's far fewer of those than Honda. While Honda parts are available for purchase online like ebay.

        Yes , Honda are better
        and for only 4 times the price ,
        and made in Thailand now ,
        and with recalls on the overheating inverter ect.
        On early eu22 anyway.
        You won’t find a second hand jap made eu20 for this price .

        This b&s has a three year warranty , with a replacement a short drive/boat away at bunnys if it carks it in the middle of a storm , flood ect .

        • Doesn't change anything I've said. Pay a few times less, spend a few times more in oil (AND fuel which I forgot before). And warranty is pretty much useless because most, maybe all manufacturers, consistently and deceptively blame the owner most times for most things thus voiding the warranty anyway. I hear it constantly in camping and caravan/motorhome forums. At least with Honda you can buy many parts and repair it yourself or a mate who knows how to repair his own mower. No chance of this with other brands like Yamaha.

          • +1

            @[Deactivated]: Oh and you won't be getting a replacement from Bunnings during a storm or flood. I live NSW where the power went out for several days a few years ago. The local Bunnings had no power either. The store was shut half of day 1, then they trucked a huge generator in inside a shipping container to power the registers and lights, and the generators were all sold out in less than 15 minutes. i.e. Someone already with a generator would use it first, then it would break down, but the few generators in Bunnings would have sold hours/days before.

          • @[Deactivated]: But you’re not dealing with the manufacturer , great thing about buying from a big box store like Bunnings is that they will replace on the spot with a receipt .
            Might be worth confirming with bunny’s before buying that this is there policy with generators ,
            but they do with everything else from what I understand .
            ( Yes , if available )

            If you’re going to recommend a Honda the old eu20i or eu30i would be my pick.

            If you can’t afford 1 then this is a tempting option if you have the need for backup power .ie QLD and northern rivers .

            • +1

              @beach bum: Yeah I guess so. It's a disgrace we have to buy with returning/refund already in mind. It takes manufacturers no more effort and only a few $ more to build these things right in the first place. e.g. Higher rated temp/quality capacitors, thicker circuit tracks, etc. But there's no ongoing money rolling in on products that last much beyond warranty.

              The 20i was great but I believe the output was slightly lower and the circuit different in that it started fewer aircons. (With the 22i there's at least one online store guaranteeing it will start your aircon.) That's easy solved though by buying a smaller or soft-start aircon.

              I hadn't heard that yet about the boards frying but I expect (if they have any brains) that will be fixed pretty fast, given most people who are unaware of the fewer-Yamaha-and-dealer-only parts issue sway between buying Honda and Yamaha.

              30i is great too, but more fuel, heavier obviously, louder… So in the case of at least some caravan parks and showgrounds, buyers will find themselves without power when ordered to turn it off and/or get lots of dagger stares and abuse from other "residents."

              • @[Deactivated]: The 30i is quieter than the 20or22i with better insulation ,larger exhaust and not that much heavier , fuel economy should be close with a similar load .

                • +2

                  @beach bum: I forget the figures now but checked a few years back, and the ongoing cost of increased fuel made the 30 not worth getting for the occasional power boost needed for say an induction hotplate for 15 minutes or aircon for a few hours in the peak of summer when you can't leave for a cooler area because you've booked the site. It made more sense to get the 20/22 and turn everything else off while cooking/cooling. (Or get two of them, link together, and only start the second one when needed so you use less fuel the other 90% of the time.) But maybe fuel used has come down now. (Different if you need all the wattage all the time though.)

                  Annoyingly "better" exhausts do little to nothing to reduce noise. It's natural to think most of small engine noise comes from the muffler because we "see" the smoke coming out and the engine vibrating, and have heard our car muffler rust out - but the excessive noise isn't the muffler. There's videos of people on youtube trying (and failing) to reduce noise this way. The reason generators are so noisy is due to the engine having less physical mass. i.e. Thinner engine walls. We're actually hearing the piston/crankshaft - the internal engine noise.

                  e.g. Car engines have more cylinders but are much quieter due to having a greater mass of metal that keeps most of the noise "inside" the engine. (Think an idling lawnmower compared to a car. Most of us could idle our cars all night long without anyone knowing. But do that with a small engine, and it's "bikies" time.

                  That's why those aluminium boxes people bolt onto the rear wall of their caravans are pointless. Just one more thin layer that does little to nothing for noise. (Better off digging a hole and lowering the generator into it.)

                  • @[Deactivated]: Anyway the 30 is quieter ,
                    You can tell the difference from the smaller version .

  • +2

    Annoying that manufacturers don't usually nominate sound levels at 25%, 50%, 75% and 100% of full load. Just to provide all the data for customers to compare. Also, they never nominate in which direction they measure - one side of the machine may be louder than the other…

    • I think the rating in Australia is 500mm from the exhaust for Engines.

      Sound will drop a few db per metre depending on environment and humidity.
      I'm not very scientific or knowledgeable in sound testing but I assume a db rating 500mm-1000mm from the user at the loudest result in regards to the angle.

      I'll take any explanation someone can provide though, I'm probably going to go down a rabbit hole on YouTube this evening on the loo

    • You can run two together in parallel with an appropriate cable.

    People talking about using it when you experience blackouts. Another option which I do, have a 2kw inverter and big jumper cables and use your car as a generator.
    Most alternators will generate at least 1kw, and here you have a large amount of fuel stored safety no spillage etc will run for much longer.
    Sure the kW/L isn’t as efficient but for the odd blackout doesn’t really matter and no additional generator maintenance is required and you are more confident it would start.
    Even for camping, unless you were running the generator all day, the car generator idea is cheaper and easier.

    • Interesting concept, and hadn't really thought it. A 2kw inverter will cost roughly half the price of this genny too wouldn't it?

      • Yeah, I bought a renogy unit for just under $300, can use it for a lot of other things too

        • Can't BELIEVE I hadn't thought about running the coffee machine off the car with an inverter when we go camping. This makes perfect sense. Just run the car for ten mins while making the perfect coffee. Absolutely brilliant. You ARE a genius! Any idea how many kw's a little 1.5L turbo diesel would generate (if the battery is healthy) via the alternator?
