Types of Inverters


power inverter
Looking to purchase a power inverter? Then, take a look at the types of inverters below and choose the one that meets your requirements. There are two types of inverters to choose from, including the modified sine and the pure sine inverters. It is also worth mentioning that this classification is made with the output waveform in mind.

  • Pure sine wave inverter

    These types of inverters are great for sensitive 240-volt devices including laptops. It can be even better than the electricity that you have in your own home. As compared to the modified sine wave type, this one can be a bit more expensive. However, it is extremely useful, allowing you to operate multiple appliances when away from main power. This type of inverter is the AC waveform you can get from the generator. The main benefit of using this device is that all your home appliances are designed to run on sine wave AC. Plus, it is a form of rising voltage. It lacks harmonic oscillations that may cause interference on the radio. However, it will cost you a fortune to generate a sine wave in an inverter because of its excellent quality.

  • Modified sine wave inverter

    The modified sine wave delivers consistent power in order to run most household appliances properly. It is extremely popular and very affordable in comparison to the pure sine wave inverter. Although they are small and lightweight, they are highly efficient. In fact, the main benefit of using a modified sine wave inverter is that it is able to power most household appliances. In comparison to the pure sine wave, it is more economical, but it is also worth mentioning that it might have some problems with various appliances, including printers, microwave ovens and digital clocks. More than 50% of your appliances run well in a modified sine wave.

Things to Consider When Picking an Inverter

As mentioned above, there are so many models of inverters in the marketplace, that finding the right one could be a backbreaking task. You may find many different sizes and multiple brands of inverters. Therefore, in order to find exactly what you need, we have gathered a few factors that you need to consider before making a purchase.

  • Choosing the right inverter size

    The size of your inverter strongly depends on the watts/amps of what you want to operate. It is advisable to opt for a larger inverter than what you need. On the other hand, it is very important to know that a big inverter cannot be used for all your household appliances. While a TV is rated at 250 watts, a microwave is rated at 1000 watts and a laptop at 95 watts. Take a look at their continuous power and add 20 percent. This way, you will notice that the needed power will be over 1600 watts. What you need to understand is that your chosen inverter should be at least 10% to 20% more than your largest load.

  • Power efficiency

    The power efficiency is an important factor to consider when purchasing a high inverter. If you are still wondering why this is so important for an inverter, remember that an inverter has the main purpose to convert DC power into AC power. The higher its efficiency is, the less power it loses in the conversion. Furthermore, the lost energy becomes heat that warms up the inverter. Therefore, before making a purchase, take a look at its power efficiency.

  • Power wattage

    As you probably know, the power wattage is directly related to the continuous power wattage that an electronic device requires to operate. Additionally, there is the surge or peak power wattage which occurs when a device is turned on. However, household appliances that are equipped with a powerful motor need a very high surge power to start up.

  • Online real reviews

    With the explosion of the internet, it is almost impossible not to find some useful reviews about your favorite models. It is recommended to read customers reviews about the product you plan to buy. You may find some useful reviews which can help you a lot in your decision.

What is Behind our Ratings


inverter
After reviewing and testing several types of inverters, we can truly confirm that it is quite complicated to find exactly what you need if you have no idea about these devices. However, as outlined above, there are a few things you need to consider when looking for an inverter.

  • Peak power

    You should probably know that an inverter needs average or typical power and surge or peak power to operate. Peak power is the power that an inverter is able to supply for short time. There are a few household appliances, especially the heavy current ones that need peak power to start up. In what regards the typical power, this is the power that an inverter provides on a regular basis. Keep in mind that it is much lower than the peak power and it is used in estimating the capacity of the battery. With this in mind, the inverters should be sized for their typical continuous power and peak load.

  • Input voltage

    An inverter needs a stable DC power source to operate. The input voltage definitely depends on various factors, including size, capacity and purpose of the device. To better understand we have gathered a few examples:

  • Smaller inverters that run from a rechargeable battery require 12V DC
  • The most common standards for home energy systems are 24, 36 and 48V DC
  • They require 200 to 400V DC, when they use power from solar panels
  • They require 300 to 450V DC, when they use power from electric car battery

If you are interested in buying an inverter, make sure you opt for one that matches the voltage of your battery. In simple terms, if you are using a 12V DC battery, make sure you opt for a 12V DC inverter.

  • Output voltage

    The alternating current (AC) voltage of an inverter is regulated at 120/240VAC. It has to be the same as the grid line voltage, even if there are changes in the load that it is driving. This way, it is able to power various electronic devices made for standard line power. Also, it is very important to know that the AC output frequency of an inverter has the same standards as power line frequency, 50 or 60 Hertz. It is important to remember that electrical devices in the United States use 120V AC power, while in the rest of the world use 220-250V AC power.

  • Batteries

    As well as using the right size electronic devices and household appliances, it is also very important to use the right battery size. Batteries are able to sustain different draw currents without producing any damages. The maximum current draw for AGM (absorbent glass mat) batteries is 30% while for gel batteries is 25% and for flooded batteries is 10%. The runtime of an inverter is strongly related to the battery power of the device. In order to prolong its runtime, additional batteries should be added.

Our Verdict


There are so many models available on the market, that finding the best product is almost impossible unless you know what to look for. It should come as no surprise that we selected the KRIËGER KR1500 as the best product in the marketplace. It provides 1500 watts of continuous rate and 3000 watts of peak power. As compared to the ERAYAK 1000W, it features an LCD screen which displays the input and the output voltage. Plus, it provides more information about the battery level. The KRIËGER KR1500 is a lightweight inverter which comes with a pretty nice design. It measures 13.1 x 5.6 x 2.7-inch and weighs no more than 5 pounds. Although it comes with a lot of features, it doesn’t have a digital volt/watt meter like the Whistler XP3000i. The digital volt/watt meter is an interesting, useful feature which helps you monitor the power usage. What put it heads and shoulders above the rest is its price tag that is more than reasonable.
