Some brands are already well established in this niche and their products have been prioritized. But other lesser-known brands were also tested. The main features considered were continuous power, peak power, power supplies, outlets, warranty, price and reliability. Inverters were immediately excluded from testing if they were unreliable or had defects that made them dangerous to use.

What you should pay attention to when buying a pure sine wave inverter

There are many features to consider before choosing the right pure sine wave inverter for you. I've put together a buying guide detailing the different types, features, and brands to consider before making your purchase. Read on to find out which features are important to you.

Types of pure sine wave inverters

pure sine waves

Pure sine waves have a smooth, continuous waveform with a uniform phase angle that allows for a clean, constant output voltage that rises and falls smoothly and changes polarity instantly when it crosses the zero volt line.

Modified sine waves

These sine waves are choppy and their voltage rises and falls abruptly. Phase angles are sharper and less uniform, resulting in harsher and less predictable voltage delivery. Polarity changes on the zero voltage line do not occur instantaneously, they take time to occur and leave gaps in the power supply to your electronics and devices.

Key Features of Pure Sine Wave Inverter

continuous power

The most important thing when buying a pure sine wave inverter is the continuous output. The continuous power should be twice as high as what your devices consume. For example, if you want to run a 150 watt TV, you need an inverter with at least 300 watts. If you want to use multiple devices at the same time, you need to add the total consumption and multiply by two to see how much continuous power you need.

The pinnacle of power

Continuous power refers to long-term operation at normal wattage, while peak power refers to the maximum wattage an inverter can deliver for a very short period of time. Many inverters have a maximum power rating, also called maximum surge power, that is twice their continuous output power. For example, a 3000 watt inverter can have a maximum output power of 6000 watts. One appliance where spike spikes could be a problem is a refrigerator. To run a refrigerator continuously you need about 800 watts, but once the compressor starts up another 1200 burst watts are required. An inverter that operates such a refrigerator would therefore require a maximum output power of 2,000 watts.

power plug

Different pure sine wave inverters have different power consumption. So you have to think about what kind of devices you usually power and what sockets they need. For example, some models have three standard US outlets but only one USB port, while other inverters may have more USB ports but fewer standard outlets.

security features

The goal of using a pure sine wave inverter is to safely power your devices. These products have a variety of security features to protect your devices. Here are the main protections to consider: thermal protection, overload protection, over-voltage protection, under-voltage protection, under-voltage protection, and short-circuit protection.

power supply

Most pure sine wave inverters come with cables connected directly to the battery terminals. However, some inverters, usually smaller ones, come with a cord that allows you to draw power from your vehicle's cigarette lighter socket. So if you plan to use your inverter in the car and on the go, you should pay attention to a cigarette lighter connection.

Brands of pure sine wave inverters


RenogyIt started as a small student project at Louisiana State University and was founded in 2010, although it manufactures its products in China. The brand produces a range of products and specializes in the renewable energy niche. The pure sine wave inverters this company makes are high quality and reliable, but they come with the price that comes with such qualities. Renogy specializes in relatively large inverters, making them better suited for people who need a 1,000- to 3,000-watt model.


specificationswas founded in 2007 and is headquartered in Paris, France. The company produces a range of electronic devices, but specializes in inverters. It has one of the widest ranges of inverters in the industry, producing models from 75 to 2,000 watts. Inverters of this brand are ideal for anyone who needs a low consumption model, like an inverter that you would use with your cigarette lighter. Bestek inverters offer excellent value for money, but the brand never compromises on the build quality of their products.


Kriegermanufactures products under its own brand and produces private label products for various customers in territories such as the USA, UK, France, Portugal, Australia, Israel and South Africa. This brand's inverters are high-end and their high prices reflect that, but they all come with a five-year guarantee so you can buy with confidence. Krieger only makes inverters from 1,100 to 4,000 watts, so it's not the brand for those who want an energy-efficient model.

Tips and Tricks

As with something you've been making for decades, along the way you'll learn a few tips and tricks for choosing and/or using the right product. This is the case with us and pure sine wave inverters. To help you fill the information gap, here's a sampling of what we've learned along the way.

  • The cigarette lighter socket in your vehicle is probably only rated for 150 watts. So if you need more power, you have to draw power directly from the battery.

FAQ on pure sine wave inverters

you have questionsUnithas answers!

Q: Do you really need a pure sine wave inverter?

A:If the device or device you are using uses an AC motor, you should probably use a pure sine wave inverter. Examples of devices that require a pure sine wave inverter are refrigerators, compressors and microwave ovens.

Q: What size do I need for a pure sine wave inverter?

A:You need a pure sine wave inverter to meet the continuous peak power demands of your devices. Your inverter should have a continuous power output that is twice the amount consumed by the devices. For example, if you are using a device that uses 200 watts of continuous power, you will need a pure sine wave inverter that is 400 watts of continuous power.

Q: Do I have to keep my inverter on all the time?

A:Some inverters can stay on all the time, while others need to be turned off when not in use. Check what the manufacturer recommends for your particular model. But while you can leave your inverter on all the time, it's still a good idea to turn it off from time to time to give its components, especially its fans, a rest.
