So without further ado, let’s continue laying the groundwork for making the right decision.

What is an Inverter Generator?

Inverter generators are still somewhat of a novelty as the technology behind them is still new. They are 3-phase generators that produce AC current. The AC current is converted to DC and inverted back to AC power in pure sine wave that provides a stable and clean energy source often more stable and with less distortion than even electricity from the public mains.

They use technology derived from a combination of both generators and inverters hence the term “inverter generators.”

Conventional Generators vs Inverter Generator

There important differences between these two types of generators that you need to know about. If you want a comprehensive explanation on generators then we recommend you read: Inverter vs Traditional Gas Generator

— Conventional Generators

The ubiquitous conventional generators have been the alternative power supply of choice over the years. The basic concept is use an energy source (fossil fuel) to power a motor-alternator combination and produce electricity. This was all well and good and all that was available for many decades but these machines produce AC sine wave power which doesn’t exactly match the power received from our local transmission stations. The result was many years of complaints of lower efficiency, power fluctuations, frequent loss of power, noise, pollution and more.

Also, any fluctuations whatsoever are usually transferred directly to the supply and will affect any appliances attached unless you take further steps to protect your gadgets and equipment.

— Inverter Generators

Inverter generators came onboard to bridge the obvious gaps left by conventional generators. They are portable generators that are easy to move around, neater to operate, compact, more efficient and durable than conventional generators.

Deciding which of these to use will depend on a number of factors for and against either of them but by the time we explain its benefits, you’ll see why an inverter generator will be the obvious better choice for your needs.

Power Efficiency

The conventional generators have proven to be unbelievably inefficient, especially the smaller sizes. Getting the power supplied to remain at a constant level that’s safe for your electronics often requires that you take extra precautions like using a stabilizer since they don’t surge well.  This is particularly an issue when planning for the starting current for electric motors that will run off of the generator. Bigger sizes do better in this regard but will waste a considerable amount of fossil fuel when they run at less than three-quarters of their full load capacity for long periods of time. Leaving them to run at the norm of 3600 rpm whatever the load is an uneconomical option many owners have to live with.

Run Time

At the design stage, the objective with traditional generators is to basically get a required amount of power to where it’s needed and keep it running at that level. With big enough fuel tanks, this is not a major challenge.  You can have them run for 72 hours and even much longer non-stop once fuel supply is uninterrupted.

Inverter generators are designed to run for averagely 8 to 10+ hours so you’ll need to bear that in mind when you’re planning to use one. On the plus side, their fuel efficient engine design translates to a fuel  savings in the range of 40% compared to their conventional brothers.

Take it Anywhere you Need Power — Yamaha EF6300iSDE

Quality of Power

As explained earlier, conventional generators are just an engine to alternator combination that will run at a speed calculated to produce the desired AC frequency.  Alternator output is proportional to the load with no processing.

The ‘line power’ output inverter generators produce is of higher quality and helps improve efficiency with a resultant less strain on machinery and connected appliances. Its engine works with an efficient alternator to also produce AC electricity but doesn’t stop there. A rectifier converts the AC power to DC, capacitors smooth it out and “invert” it back into clean AC power to a specified frequency and voltage. The power produced is very well regulated, consistent and clean (hence the term pure sine wave).

When you consider the fact that most of the gadgets and electronics we use today, like mobile phones and laptops, come with highly sensitive microprocessors that are easily damaged with poor quality power supply, you’ll understand why a cleaner source is so important.

Inverter Generators Produce Clean Power

Portability

Inverter generators are surprisingly small and are being designed to get even smaller with lesser moving parts despite their power output. Many are just some inches larger than a medium sized briefcase. Many range in size from 30lbs to 50lbs. transporting them is a breeze using a car or other form of transportation.

The fuel tank, wheels and metal frame alone of a traditional generator make it heavy and bulky and can be a challenge to maneuver.

Noise

Do you know that the average conventional generator will produce sound levels of up to 75 decibels when in operation? That’s the same as an airplane jet engine. This is because they have to run at a constant speed to maintain the quality of power produced/desired, many times at full speed even.

Hands-down, the inverter generators win here as they are designed to be as quiet as possible. They come with mufflers, quieter engines and innovative sound-dampening technology so users are often surprised at how quiet they are. Additionally, the engine can adjust its speed to match the load demanded at any point in time using microprocessors and specially designed electronics. You’ll easily find models that will run at about 50 decibels, the same sound level as an everyday human conversation.

Max Power Output

Conventional generators are at the top of the game in this regard. You can find them from as little as 500 watts output to custom made models of up to 50,000 watts and above.

Inverter generators are made to be portable and quieter. Their output is much smaller ranging from 1000 watts to 6000+ watts. But don’t rule them out on account of this just yet. The parallel operation option is an arrangement that allows you to pair identical capacity inverter generators and effectively double the output. This arrangement allows you to still enjoy the benefits without resorting to the conventional models.

Price

If there’s only one area that conventional generating sets beat inverters, it’s in the area of price. No doubt about it, comparing units of the same capacity and output, inverter generators cost much more than traditional models. You need to consider if you can forgo the many benefits of models like the Yamaha EF6300iSDE just because of the price. From experience, we can safely say that in the long term, the many advantages and savings on fuel consumption are well worth the price tag. Our maintenance tips later in this guide will also help you get the best out of your investment.

Why buy an inverter generator?

By now you’re probably wondering if you need one of these machines. Here are a few scenarios where you’ll want to buy one.

They are indispensable for the great outdoors. Going camping, fishing or hunting anytime soon and you want to have at least some level of comfort? Buy one of these. It’ll keep your phones charged and provide other electricity powered comforts with less noise and inconvenience.

You can use them in your RVs and at camping sites. The reduced noise level is an added advantage to avoid angry neighbors knocking at your door at midnight (conventional generators will get a lot of angry knocks, guaranteed).

If you live in an area that has frequent storm related power outages, it’s advisable to get one.

Construction workers use them a lot especially when they need to work in the early hours of the morning in residential areas. The low noise levels allows them work interrupted.

— Important Features to Consider When Buying

All inverter generators are not the same. The technology behind them may be but in the field, some factors can affect how much you enjoy using it. Here are a few tips to help you choose one:

Some models come with controls that easily switch automatic power saving and power-boost mode when there’s need for short surges of power.

Look for models with smart control panels that help you monitor the voltage output, frequency, run time, overload warnings and so on.

Though they are designed to be relatively quiet, noise levels will vary from one brand/model to the other. The load at which it’s running will also affect the noise level. Generally, you can expect them to run at about 50 to 60 decibels.

Buy a unit that is easy to maintain, operate and move around.

Some, not all, units come with accessories like parallel cables (for parallel operation connection), spark plug wrench and battery-charging cable etc.

— How big of a generator do you need?

Knowing the right size of inverter generator that will supply your power needs and still remain within your budget will save you a lot of frustration, false starts and money too.

Start by checking the power requirements for every appliance you intend connecting to the inverter. Ideally, the unit should run at not more than 70 to 75% of its maximum load for extended periods of time. If you will be running a number of appliances with starter motors, it may be best you consult an expert to help you do the calculations. Below is a general guide to help you.

Small Inverters up to 1KW (1000 watts) — Can power laptops (0.65KW) and other small appliances like coffee makers, mobile phones, tablets and smaller flat screen TVs.

Medium Sized Inverter Generators up to 3KW (3000 watts) — These will power microwaves, hand held hair dryers, toasters, small air conditioning units and so on. Note that you’ll need to rotate appliances at some point especially when you are running the air conditioning so as not to overload the unit.

Large Inverter Generators up to 6KW+ (6000 watts) — If you don’t want the hassle of constantly monitoring the overload indicators and rotating appliances, get a larger model. It will also save you from having to top up fuel at regular intervals. These sizes will power your fridge, cooker, microwave and other appliances at the same time.

Remember that it’s always better to err on the side of caution and go for a bigger rather than smaller model especially if you have many people using it. The fuel economy design of most of these inverters will match engine speed to load so you won’t lose much as compared to this same situation using a conventional generator.

Maintenance | Inverter Generator

This is an expensive piece of machinery you can’t afford to mishandle. A little bit of extra care will allow you use it for many years. Here are a few thing you can do in this regard.

• Charge the battery at intervals. Once a month would do. Run it for about 30 minutes or just plug the battery into a charger.
• Monitor the display panel for any LED warning lights flashing while it’s in operation. Especially for overload warnings.
• If you’re going to leave it idle for a long time (6 months to 1 year), ensure you drain the oil. Use a flat and shallow oil pan to do this. Also drain the gas and use foamed oil to spray the engine and coat all the surfaces. Carefully disconnect the wires and clean them to prevent corrosion.
• Always keep the unit away from any source of humidity and of course, regularly wipe the exterior with a soft cotton cloth to keep it clean.

Final Thoughts : Yamaha Generators

Getting an inverter generator to replace your conventional one should not be so hard a decision to make. We believe the facts discussed here are the most critical ones you’ll need to consider and will help you make the right decision.

Yamaha is one brand you need to seriously look at as it continues to awe with its compact models and innovations in cutting edge technology. Best of all, the peace of mind you’ll have when running your delicate electronics is something that will make life easier for everyone involved. Yes, they are a bit expensive compared to other economy names out there but the value they offer means they remain in a class of their own.

If you want a cheap (and powerful) gas generator there are plenty of those out there but all generators are not created equally so it’s important that you decide upon your priorities before making a decision on which generator to buy.

If you want a balanced generator that is quiet, powerful and can run your sensitive tools and electronics then I absolutely recommend the Yamaha EF6300iSDE. The only negatives art that it’s expensive and doesn’t have the option to run a second unit in parallel. Not sure why Yamaha didn’t add that feature since it’s so common nowadays. But luckily you do have an alternative with the Honda EU7000iS which, although a little more expensive, is actually better and has the option to run in parallel if (and when) you want to scale your power needs.
