Inverter source have become increasingly popular over the preceding few age . They are promoted as being well-situated to use , quieter , and more economical than gas generator . They also shoot a line few emission , so they are more eco - well-disposed .
Exactly what is an inverter source ? Both modern and conventional generators produce electrical energy . They typically are portable and pass on some form of fuel to convert mechanical vitality into jump current ( AC ) power . Through fresh applied science , inverter author then convert the AC office into verbatim current ( DC ) power , then back into AC power . The result is a more stable and cleaner business leader genesis than in schematic generator technology .

But before you junk your erstwhile flatulence - guzzle ogre and trounce out on the late technology , we ought to reckon beyond the plug , and answer a few key questions . What advantages does an inverter source have over the regular models we ’ve been using for decade ? What are the downside ?
TRUE: Inverter generators run more quietly than regular generators.
First off , inverter generators have much better mufflers than those on established generators , which can expect like picayune more than a dome can with holes in it . Second , a standard generator usually has a fixed speed , whereas on aquiet inverter generator , microprocessors regulate output .
Clement Feng , vice President of the United States of product management atBriggs & Stratton Energy Solutions , says : “ A key reason why inverter generators operate more efficiently and quieter than ceremonious generators is because they align their locomotive engine running speed based on the electrical load . It ’s similar to how a automobile engine revs up when it needs to provide more power . established generator always run at the same speed , typically 3,600 RPM [ gyration per minute ] , no matter the electrical requirement . ”
It has also been said that inverter generator are quieter simply because they are smaller . Although historically this was true , they are stupefy bigger and more powerful all the time . Even prominent inverter generator still produce less haphazardness than their ceremonious counterpart , however .

FALSE: An inverter generator produces less power than a comparable portable generator model.
Technically , there is some truth to this downside of inverter generators . But generator baron is rated in watts ( W ) , so a 5,000W portable inverter generator produces precisely the same ability as a corresponding 5,000W established portable generator . Motor size of typical contender are similar too . The conventionalChampion 5,000W generatorhas a 224cc gasoline engine , and so does the equivalent5,000W inverter from Westinghouse .
However , if maximum top executive is the goal , then presently even the largest inverter generators can not quite match steady models . The largest inverter we base is aDuromaxrated at 16,000 watts , whereas the largest conventional find is a 28,000W modelling fromWestinghouse .
TRUE: Inverter generators often are more fuel-efficient.
This is generally genuine , but modern conventional models can also be very effective . It can be surd to tell , since manufacturer do n’t often give fuel consumption figures for generators . or else , they give figure runtimes . The challenge here is that these are never ply at 100 percent load ( maximum superpower output ) . Commonly , the runtime indicates 50 pct load , but even this is not a standard .
Once again , the Champion and Westinghouse role model offer a comparability . The ceremonious Champion runs for up to 14 hours at 50 percent load , and has a 5 - gallon fuel tank . The inverter Westinghouse run away for up to 18 hour from a 3.4 - gallon tank but that ’s at 25 pct onus . So while it ’s true that inverter generators are very fuel efficient it ’s crucial to assess each model on its full specifications .
FALSE: All inverter generators run exclusively on gasoline as a fuel source.
This was true a few years ago , because when they first seem , a gasoline inverter generator was your only choice , but this is no longer the case . Today , many of thebest inverter generatorsare available as dual - fuel manikin .
The twofold fuel we are talking about are gasoline and propane . In other words , dual - fuel inverter source can be attached to a standard 20 - pound propane army tank as an substitute fuel source . It ’s important to point out that maximum office outturn is lower when using propane because it does n’t burn as expeditiously as gasoline . For example , the Westinghouse generator featured above drops from 5,000 watts to 4,500 watts while on propane as a source .
TRUE: Inverter AC power is safer for plugged-in electronics.
This is genuine , with some elucidation . Most conventional generators also bring forth AC power . The problem is that their output fluctuates . This is called entire harmonic distortion ( THD ) . Anything above 6 pct THD can harm electronic devices , and conventional generators deliver anywhere from 9 pct to 30 percent .
The THD on inverter author can be as humiliated as 3 pct , and rarely varies . In fact this is where the “ inverter ” name originates , since an inverter author first produces received AC , then inverts it to DC . Complex electronics pick up the signal , and invert it back to AC that is now safe for laptops , tablets , phones , and other sensitive electronics .
FALSE: Inverter generators are less expensive than most portable generators.
The investment you want for a little inverter generator will generally purchase you a considerably more powerful conventional model . Whether it ’s deserving the investment will depend on your needs . If you require something lightweight that ’s safe for electronics , an inverter author is a must . If you want something that canpower the whole house , it ’s likely to be a conventional mannikin .
That said , it is possible to find some very good deals on inverter generators . When investigating thebest author brandsrecently , we detect that Ryobi , WEN , PowerSmart and Sportsman all offer competitive option .
TRUE: Generally small and lightweight, inverter generators are easy to set up and transport.
This is how inverter generator ab initio gained popularity . They were much humble and lighter than conventional models , making it more practical to take a generator camping or tailgating . Most were also easy to start , something that was often a challenge with traditional generators .
However , inverter generator are n’t all small . For exercise , theDuromax 16,000 wattis a prominent enough inverter author for dwelling function , and meets many of the requirements found in our utilitarian guide tohow big of a author you needin an emergency .
FALSE: All running inverter generators need more frequent refueling.
This depends on one ’s definition of “ frequent . ” ThePowerSmart 2,350 watt inverter generatoris a compact example that weighs just 40 pounds . The fuel tank is only 1.05 gallons , but it will course for up to 10.5 hours at 25 percentage onus . The popularHonda EU2200has a fuel armoured combat vehicle of just 0.95 gallons , but will extend for around 8 hours at 25 percent load . Yes , there are conventional generators that need refueling less often , but they are also much big and enceinte . It ’s important to assess which matters most before choose .
TRUE: Many inverter generators can be connected together in parallel for more power.
Connecting inverter generator in analogue can literally double the power production available . However , it ’s not simply a head of blend and matching any two inverter generator . Some are not parallel - adequate to . Those that are must also be of the same output potential and frequency to keep damage to one or the other . They do n’t have to be selfsame models , but it is the easiest route . You will also need a suitable parallel cablegram or outfit to yoke them up .
FALSE: Inverter generator lifespan tends to be on the shorter side.
Lifespan is very difficult to assess because conditions of use and maintenance can make a huge difference . According to several independent sources , inverter author typically will last between 1,000 and 2,000 minute when in good order looked after . With ordinary use , this could equate to around 10 to 15 years . That ’s not really a short lifespan , and is similar to lifetime quoted for conventional portable generators .
A note about generator safety : All generator produce carbon monoxide ( CO ) which is potentially lethal . Even small-scale inverter generators should never be used indoors . TheAmerican Red Crossoffers more elaborated prophylactic advice .
