Buyers’ Guide (How to Buy the Best Pure Sine Inverter for You)
1. Know the different types of pure sine wave inverters available
Low-frequency pure sine wave inverters use a large copper transformer. They tend to be bigger, are more expensive, and weigh more. Low-frequency units tend to be better for equipment that requires a high starting power. Compressors and air conditioners often need a low-frequency unit as well as any equipment that you’ll use regularly and for long periods.
High-frequency pure sine wave inverters use smaller transformers and other electrical components. They tend to be much lighter and cost less. For occasional users and smaller electronic equipment and devices, a high-frequency unit works well.
If you’d like a smaller unit that’s easy to carry around and fits into smaller spaces, a portable pure sine wave power inverter fits the bill. Similar to our top-rated solar generator, these portable units will weigh very little and sometimes come with a convenient handle built-in. They’ll also, often come with a durable cigarette lighter for plugging into your vehicle on the go.
Commercial grade pure sine wave inverters will supply higher watts of continuous power for industrial applications. Commercial grade units deliver enough power to run higher-end equipment that requires substantial amounts of electricity.
These units will be much heavier than the more portable types and are better suited for a more permanent position.
2. Know how much wattage you need
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, and even our best off-grid refrigerator of the year fits into this wattage range.
Other equipment that typically fits within this range includes ¼” and ½” drills, chargers for battery-powered tools, credit card machines, engine block heaters, and halogen flood lamps (6).
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 (6).
To further understand sizing in this wattage range, this article is particularly helpful because it shows you how to size an inverter efficiently to run a microwave.
Devices and appliances that have an operating wattage of 3000 watts or more include convection toaster ovens, air compressors, electric chainsaws, and high-pressure washers (6).
Many pure sine ac power inverters for RVs fit in this category, as their equipment often requires higher power draws. For my 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.
3. Find the Top Deal for You
Warranties for pure sine wave inverters will vary from manufacturer to manufacturer. Pay attention to the warranty, return policy, and other policies, and make a comparison. The warranty on most pure sine wave inverters will be somewhere between one to five years, similar to most solar equipment – like our top solar dusk to dawn lights. Choosing solar equipment with a decent warranty will ease your mind if anything does go wrong with your units in the future.
Pure sine wave inverters are available for a wide range of prices. As you compare prices, features, and power, also pay attention to shipping costs and policies. If you have a camping trip coming up or you’re preparing for another time-sensitive situation, make sure your new pure sine wave power inverter is going to arrive on time and that it won’t cost too much to have it delivered.
You can often find limited-time deals on pure sine wave inverters, so keep an eye out for promo codes or other offers while shopping. And if you find one that meets your requirements and comes recommended, you might want to jump on it before the deal runs out!
Then, to always keep tabs on the hottest limited-time deals in the solar industry, bookmark Your Energy Blog and our popular posts like our solar lamp post reviews. That way, you’ll have immediate access to the web’s one-stop shop for all things solar.
The cost will vary from unit to unit and will increase with the number of added features and higher power, similar to the most solar products, like solar-powered gate openers. Be sure to compare prices of similar models and take into account any deals, offers, and the shipping cost when determining the final price. Also, everyone loves a great deal, but don’t settle for a unit that you may have to upgrade later just because the price looks good.
A high-quality pure sine wave power inverter should last for quite some time and isn’t meant to be purchased repeatedly. It can be frustrating to buy a unit with a lower price tag and then have to spend more money later once you discover you need more power to run all your devices and equipment. Higher price tags can seem daunting, but remember, you’re paying for quality, efficiency, and power.
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, but if your device uses a rectifier or can be powered by a DC adapter, it may not be necessary. (7)
For more information on this, you can check out our guide comparing pure sine wave inverters vs modified sine wave inverters.
The main advantage of a pure sine wave inverter over other types of inverters is that all appliances and devices are designed to use the sine wave. (8) Using a pure sine wave power inverter means your devices and appliances will run more effectively and will be better protected.
The best pure sine wave inverter is ultimately the one that fits your needs the most. The optimal fit for you will be the one that has the necessary power and features for your intended use. You’ll also want to look for an energy-efficient unit that’s quiet and has safety features to protect your appliances and devices.
