How To Choose The Best Pure Sine Wave Inverter For You (Top 3 Tips)

1. Find out how much Wattage you need

When picking a pure sine wave inverter, the most important factor to keep in mind is its power output, which is rated in terms of Watts: 

0 – 1000W

Devices and appliances in the 0 to 1000 watt range will generally include cell phones, ceiling fans, DVD players, gaming consoles, incandescent light bulbs, mini Christmas lights, computers and monitors, laptops, satellite receivers, stereos, tablets, TVs, etc. Even our best off-grid refrigerator of the year fits into this wattage range.

Other equipment that can typically be powered by such inverters includes ¼” and ½” drills, chargers for battery-powered tools, credit card machines, engine block heaters, and halogen flood lamps (8).

1000 – 2000W

Devices and appliances in the 1000 to 2000 watt range typically include coffee makers, hairdryers, irons, microwave ovens, laser printers and fax machines, toasters, and vacuum cleaners. This range also includes equipment like 8” circular saws, bucket heaters, fiber optic splicers, 4 ½” grinders, hammer drills, heat guns, reciprocating saws, shop vacs, space heaters, and table saws.

If you’re choosing an inverter for your microwave, we recommend reading this article first to know what to look out for (and prevent any potential mishaps!). 

2000-3000W+

Devices and appliances with an operating wattage of 2000 watts or more include convection toaster ovens, air compressors, air conditioners, electric chainsaws, and high-pressure washers.

Many pure sine AC power inverters for RVs fit in this category, as their equipment often requires higher power draws. For all the RV owners out there, you can check out our guide on how to install an inverter in a camper to see what your potential setup could look like.

If you’re still not sure about how much power you’ll be needing, we recommend reading this solar generator buying guide and following the steps to create a table of all the devices you’ll be running on your inverter. This will help you plan your usage effectively. 

2. Consider the peak output, efficiency, and protection system

Pure sine wave inverters generally also have a surge output (or peak) rating, a maximum efficiency, and certain protection circuits inside them. To make the right decision, you should consider these based on your budget and use cases: 

Surge Output

Whenever a device is switched on, there’s usually a short, very high intake of current into the device. This especially happens with high-power appliances like blow dryers and microwaves. This is known as a ‘surge’. 

These surges can be up to twice as powerful as the actual operating wattage of the device. So, a 1000W microwave may have a surge of over 2000W. Hence, you have to make sure that your inverter’s surge rating can handle this. Else, it may fail and damage the device you’re trying to run.

Efficiency

The efficiency of an inverter refers to how it converts the input power (from the battery) into output power. Essentially, a more efficient inverter means that it will provide higher output power for a lower input power; hence your battery will last longer too. 

As we mentioned, choosing an inverter that’s 20-30% larger than your required power is a safe option as some inverters may have reduced efficiency under heavy load. This may result in damage to your appliances as well. 

Protection

Having an inverter stop working when you need it the most is a bad experience, but what’s worse? An inverter that ends up damaging your expensive appliances. To avoid that, high-quality inverters have a bunch of different protection circuits in-built that’ll prevent electrical malfunctions. 

The common protection systems found cover overload, under/over-voltage, overheating, and short-circuiting. Some go beyond this with GFCI ports, which prevent grounding errors that could cause shock. 

To ensure that inverter manufacturers stick to high-quality materials, there are several safety standards that they need to be certified by. We recommend choosing one of these if safety and reliability are your main concerns. 

If you’re going to use your inverter regularly, we recommend choosing one with the highest protection systems. Some inverters also feature a Universal Protection Circuit (UPC) that’s even more robust and reliable than individual systems.

3. What other features do you need? 

We’ve already discussed the essential factors to look out for. But what other features do you need? Inverters nowadays include a host of features that are designed to make your life easier and more comfortable. Some of these include: 

• An LED display to track the current power usage
• LED indicators for any faults/errors 
• A remote toggle switch to control the inverter 
• USB ports to charge your electronics 
• Extended warranties for better reliability 
• Portable design with carrying handles

Ultimately, you should pick the one that falls within your budget, but still offers all the features and the power you’ll be needing. 

Our Final Verdict: How to Buy the Best Pure Sine Wave Inverter Today

Now that you’ve seen all our reviews of the top pure sine wave inverters to choose from, all that’s left to do is select the model that’s right for you. If you’re still not entirely sure which one to choose, here’s a wrap-up:

For the best of the best, we can’t recommend the AIMS 3000W inverter enough. It’s reliable, robust, safety-listed, sleek, and still comes in at an affordable price.

FAQs

• Do you really need a pure sine wave inverter?

  It all depends on the types of devices or appliances you’ll be running. If your appliance uses a motor or is a delicate piece of medical equipment, you probably need a pure sine wave power inverter for efficiency. But if your device uses a rectifier or can be powered by a DC (direct current) adapter, it may not be necessary (9). A modified sine wave inverter may work for you in that case (and be cheaper!).

  For more information on this, you can check out our guide comparing pure sine wave inverters vs modified sine wave inverters.

• What is the main advantage of a pure sine wave inverter?

  The main advantage of a pure sine wave inverter over other inverters is that it simulates the AC current you receive at home. Almost all appliances and electronics are designed to use this AC sine wave (10). Hence, using a pure sine wave power inverter means your appliances will run more effectively and will be better protected from malfunctions, as compared to modified sine wave inverters.

• What is the largest pure sine wave inverter?

  The largest pure sine wave inverter, as per our review, is the EDECOA 3500W. It offers a continuous output of 3500 Watts, with surge protection up to 7000W. This makes it one of the most powerful and largest consumer-level pure sine wave inverters available in the market. It’s the best choice for energy-hungry appliances like microwaves and refrigerators.
