Keep reading as we will be discussing exactly what you’re looking for. On this website, we will go into detail on the best wave inverters, which if you didn’t know, are pure sine wave inverters (for reasons discussed below). On top of this, we will include expert reviews in order to substantiate our claims. There are a number of different wave inverters, each serving unique purposes. As a result, we creating this pure sine wave inverter buying guide just for you! Read on…

So what is a wave inverter?

A power inverter is a device that changes the current from DC (direct current) to AC (alternating current). Power inverters are used for a wide range of applications. A lot of portable consumer electronic devices that use batteries need power inverters to produce AC power. You came across this website because you are most likely interested in pure sine wave inverters. A pure sine wave inverter (to be referred as a “PSWI”) is a type of power inverter that produces a smooth sinusoidal AC waveform.Their counterpart, which are slightly cheaper, are called modified sine wave. A modified sine wave will provide peak voltage for just a few milliseconds. A PSWI will provide a much more gradual peak.

Why is a pure sine wave inverter preferred?

While a modified sine wave inverter can be used for a number of electronics. A pure sine wave inverter is preferred because the majority of electronic products and appliances that need to be plugged in work well with the standard power you receive from utilities as standard utility electricity is a pure sine wave. These electronic products were designed to work on a pure sine wave! With the increasing sensitivity of modern electronics and the exponential growth in technological advancements, more and more products require a true sine wave in order to operate effectively.

Determine which PSWI is best for you

If you are looking to purchase a PSW, it is no easy task as there are many models and they each have different features. Depending on your application, it is recommended that you thoroughly consider the alternatives and make an educated choice. The last thing you want to do is purchase a 400W power inverter and plug in an appliance that requires 1500W! As with any purchase, it is best to be informed! If you will be spending thousands of dollars on your electronics, it is necessary that you take the time to do your research. There are many factors to consider and we will do our best to outline them below. If we fail to mention something or if you have any specific questions, feel free to contact us or leave a comment.

Watt Power

First off, PSWI come in different watt sizes. Do you need a 1000W or a 2500W inverter? A laptop and a generator will not be able to run on the same power inverter. Others are safer, more efficient or come with a multitude of features like LCD display. All these features and differences in size add to the cost of the inverter. If you are cost sensitive, only a small sine wave inverter will work for you. However, this will limit your use. Our website features PSWI that come in a wide range of sizes. You will find them as small as 180 watts which can be powered by a USB all the way to the 12,000-15,000 watt range. Now you may be asking, I need a wave inverter for X what Y watt size should I get? We got you covered! Take a look at our Pure Sine Wave Inverter Watt Comparison Table where we list out the various power sizes and their recommended use.  It is recommended that you purchase an inverter with about 10% to 20% more power than what you need.

When you will be browsing our reviews, you will see the term “peak load” and “continuous load”. Peak load is the maximum capacity the PSWI can incur. As an example, say you wanted to start a motor. A motor needs an initial surge of high power to get it started and then it can run on less continuous power.  Say it needs 3,000 watts to get started and then it can continuously run at 1,500 watts. In such a case, you will look for a PSWI that can handle a peak load of at least 3,000 watts (4,000 would be recommended) and can continuously run at at least 1,500 watts (2,000 would be recommended). When you see the advertised watt they generally refer to the continuous load.

Features

Pure sine wave inverters come with a number of features. Small are as basic as you can imagine. Simply an outlet to plug in your device. Nothing more, nothing less. The more you are willing to pay, the more interesting the range of features. Technological advancements have grown over the years and this has spilled over to power inverters. On our website, we review a wide range of wave inverters so whatever feature you see below, you can surely find a PSWI with one of those features!

FeatureDescription
USB PortsWith the growth of small electronic devices that can be charged by USB, power inverters have grown to include USB connections. This feature is mostly seen on inverters will smaller watt sizes.
LCD displayMore expensive inverters will have LED displays. These indicate your power levels.
Solar chargerNot as efficient as AC power inverters, you can now find inverters that utilize green solar energy in order to charge your devices.
Power jump starterHow great would it be if you're car battery died and you had an inverter with power jump starter than can connect directly to your car battery?
Built-in air compressorInverters that are designed specifically for car use may include a built-in air compressor. This can be especially useful to pump tires and even sports equipment.
Overload & overheat protectionThis is a standard feature that you should find on any quality inverter. This ensures that the PSWI does not blow up if you plug in too high of a powered device! Pricier inverters even contain audible alarms to let you know when you are getting close to peak. If the inverter you are looking at purchasing is not equipped with this featured, I'd be worried and would stay away.

Cost

The cost varies from PSWI to PSWI. As we said earlier, pure sine wave inverters are generally more expensive than regular power inverters or modified sine wave inverters. The cost also increases with the number of features and power. On our website, we will feature reviews for a number of different PSWIs and some will surely be in your price range, whether you are looking for a low price one or a higher priced one with a lot of power and many features. Nevertheless, there are many deals to be had if you are purchasing them on the Internet. We will do our best to update you with the latest deals. If you are looking for a particular inverter at a certain price, send us an email or leave us a comment and our team will research and find you what you’re looking for!

    I am going around Australia free camping and I am looking for as a priority a very reliable PSW for all round use one that won’t fail on me. If you known a very reliable brand on the Australian market that would be great. I have a120 watt glass Matt battery and a180watt solar pannel. I’m not sure all the things I will be running at this stage but possibly general house appliances like a 1000w toaster for example would be greatful for your help. Thank and all the best Michelle.

  • kay says:

    Thanks,what size of inverter do I need to power three 1 HP air condition and how many watts of solar do I need to charge a 150amps /48volts battery

    • Al says:

      You need a lo frequency inverter of 20,000 watts to start and run 3 A/C
      if they have a chance of starting at the same time also about 10, ooo watts of solar panels . This battery is not large enough to run the a/c units continuously !

    • Ken in Las Vegas, NV says:

      It is not reasonable to run super high power appliances from solar charged batteries, unless it is for very short periods (hair dryer, toaster oven, skill saw, drill, microwave, electric kettle, etc.). Cooking, heating and cooling will have to be done with very little electricity– maybe LP gas or alcohol for cooking, LP gas for hot water, LP gas or wood stove for heat, fan or evaporative cooler for cooling, etc.

  • James Millington says:

    Will a whistler pro 3000 Watt psi handle a 800 Watt refrigerator. Concerned about starting wattage.

  • Mike Hart says:

    What is the best inverter to use to run a 220 volt 2 hp submergible pump, a refrigerator, and freezer,from a battery bank that will be charged by a water powered generator

  • Don MacGlashan says:

    Although a GFI (ground fault interrupter) may be a good feature if operating ini a dry area like in a heated, dry building, they may not be useful in a car, truck, or RV. Most of them are too moisture sensitive and annoyingly keep tripping. I think for vehicle use, a inverter without the GFI feature is a better choice.

    Why was Exeltech not mentioned? From my research, this is the best of the best pure sinewave inverters, of course it may be more expensive than other brands. I read that it is used in medical equipment, and studio/sound devices because of low noise. It is also used across 20 US embassies and not one has failed.

  • Lester says:

    Hi, good day. I am planning to put up a 100W solar panel and planning to use it on 2 submersible pump for my koi pond, 25W and 16W aquamaster brand. Any recommendation for the type of PSWI I need to use. Also, are these just the stuff I need for setting up a solar power system (solar panel and PSWI). Your respond will be greatly appreciated. Many thanks.

    • Bill says:

      Battery and a charge controller if you plan to run the system around the clock. Otherwise it will only run in the day.

    Hello. We are living off grid out of a 5th wheel trailer. We have two 6v batteries and will recharge them with a generator. We will look to add a portable solar panel in the future. Our goal is to run a toaster oven or an instant hot water heater (1500w) and our central heating at the same time off of just batteries, so I was looking at a 2000-3000+Watt invertor. Do you have any recommendations for a suitable unit for us to look into? Thanks
