The best pure sine wave inverters are the ones that can keep multiple sensitive electronics charged while protecting them from harm. Another important characteristics of the ideal pure sine inverter are solid warranties. If something goes wrong with the device, size, and weight, that won’t be too cumbersome for the intended use and comes with features that make them convenient. Check out this article for the best pure sine wave inverter.

Our Top Choices

Because the essential aspect of a pure sine wave inverter is to provide power to sensitive electronics, it’s important to pick one that will provide enough power. Individuals wishing to run medical equipment when the power goes out will have different needs than someone wanting to charge their laptop in the car. The higher the wattage, the more items or the more energy-hungry items can be used.

Having a device that provides several outlets will also be much more convenient depending on the use. Someone running multiple devices will want multiple outlets, whereas someone plugging their power inverter into a camper won’t need as many. The size of the device and its weight can also play a factor as certain scenarios may require something a little more mobile while others can be stationary.

The built-in protection systems and the warranty are major factors in making the best pure sine wave inverter. If one is being used daily for an off-the-grid home or providing power to someone living in an RV, then having full standard protection may not be enough. Additional features like an automatic restart function or Eco mode should also be taken into consideration. Then at the end of the day, the impact a new pure sine wave power inverter will have on a person’s checkbook should also be factored in.

Our List Of Best Pure Sine Wave Inverter

GoWise PS1004 Continuous Pure Sine Wave Inverter

GoWise PS1004 Continuous InverterIn terms of power output and convenience, the GoWise PS1004 Continuous Inverter makes it one of the best if not the best pure sine wave inverter on the market. It’s also surprisingly light in terms of weight compared to others on the list. The tradeoff, of course, is a device that is not only more expensive than modified sine wave inverters but other pure sine wave inverters on this list.

Power Output & Battery Requirements

The GoWise PS1004 pure sine wave inverter provides a continuous 3000 watts of energy on par with the WZRELB 3000W. It can achieve 6000 watts of surge power which, as opposed to a modified sine wave inverter, can actually be tapped into occasionally, though definitely not relied upon.

Like other inverters, it requires a 12-volt battery to function. The only one that doesn’t is the WZRELB 300W which requires a 24-volt battery.

Outlets

The pure sine wave inverter comes with three AC power outlets. The only other devices with that many AC outlets are the GoWise 2000W and the Voltworks 1500W, which both have less power. There is also a single USB port, surpassed by the Voltworks 1500 W, with two USB ports.

This is easily the best inverter in Ac outlets and raw power, but users may consider choosing the Voltworks 1500W to get the extra USB port.

Protection & Warranty

As is standard with pure sine inverters, the GoWise PS1004 comes with full protection. There is also a low voltage alarm to indicate when a connected battery is running low on charge, something shared by every device on the list except the Giandel 2200W.

Along with the other pure sine wave inverters in this review, a convenient LED display indicates whatever problems may be occurring along with current usage.

The GoWise PS1004 comes with a standard one-year warranty for replacement and repairs. The Giandel 2200W, Voltworks 1500W, BESTEK 300W, and Go Power! GP-SW3000-12 all have superior warranties by comparison.

Dimensions

At 22 x 9.3 x 4 inches, this pure sine wave inverter is a bit bigger than other options like the WZRELB 3000W, GoWise 2000W, Giandel 2200W, or the Go Power! GP-SW3000-12. In fact, it’s the largest inverter on the list, which could be an issue depending on the space it’s meant for.

This pure sine wave inverter is surprisingly light at 9.9 pounds, making it almost the same weight as the Voltworks 1500W, which weighs 8.96 pounds and has half the output voltage. It’s even less than half the weight of the Go Power! GP-Sw3000-12 at 21 pounds.

Other Product Notes

The device comes with a standard remote that’s includes every other option on the list. It also comes with a set of battery cables that is also standard, except for the Renogy 1000W or the Go Power! GP-SW3000-12. the inclusion of a battery cable isn’t all that notable, as the average user will likely replace any of the ones included on any device in this list.

Pricing is fairly high when compared to the WZREB 3000W with a similar offering. That being said, it’s almost half the price of the Go Power! GP-SW3000-12, so it isn’t the most expensive out there.

Pros

  • With three AC outlets, it has more than the WZRELB 300W power inverter.
  • At 9.9 pounds, it’s more lightweight than the GoWise 200W power inverter.
  • With 3000 watts, it provides more continuous power than the Giandel 2200W pure sine wave inverter.
  • It’s almost half the price of the Go Power! GP-SW3000-12 pure sine wave inverter.

WZRELB 3000W Pure Sine Wave Inverter

WZRELB 3000W Pure Sine Wave InverterThe WZRELB 3000W is a great option for situations where modified sine wave inverters just aren’t up to the task of providing continuous power for sensitive electronics. It’s a cheaper but slightly heavier alternative to the GoWise PS1004 meant to be used in RVs, homes, and other heavy-duty projects.

Power Output & Battery Requirements

This pure sine inverter provides 3000 watts of continuous power, just like the GoWise PS1004 or the GO Power! GP-SW3000-12. It also has 6000 watts of surge power, but it’s not reliable at this level, like modified inverters.

Unlike other inverters on this list, the WZRELB actually requires a single 24-volt battery or two 12 volt batteries to provide the DC power. Every other option, even the bulky Go Power! GP-SW3000-12 only requires a 12-volt battery or equivalent solar panels.

Outlets

This pure sine wave inverter has two external AC power outlets like the Giandel 2200W, the BESTEK 300W, or the Go Power! GP-SW3000-12. The GoWise PS1004, the GoWise 2000W, and the Voltworks 1500W come with an extra AC outlet.

Unlike most of the other options, the WZRELB 3000W doesn’t come with a USB port. The only other inverter on this list that doesn’t have at least one USB port is the Renogy 1000W.

Protection & Warranty

Like all pure sine wave inverters on the market, it comes with the standard full protection measures. It does stand out by using a replaceable 50 amp fuse. The only other device that uses replaceable 50 amp fuses in the Voltworks 1500W.

It stands above the Giandel 2200W in that it does come with a low voltage alarm to indicate an issue with dc power.

There is a standard one-year warranty on the power inverter for both repairs and replacement, just like many of the other devices on this list. The Giandel 2200W, Voltworks 1500W, BESTEK 300W, and the Go Power! GP-SW3000-12 comes with better warranties.

Dimensions

The standard aluminum casing is a bit large at 21.7 x 9.5 x 3.7 inches though this is smaller than the GoWise PS1004. It weighs 11.42 pounds which is around the same weight as the GoWise 2000W or the Giandel 2200W. The GoWise PS1004 is much lighter while offering the same output voltage.

Other Product Notes

There really isn’t anything terribly unique about the WZRELB 3000W. It comes with the same remote control that the other devices have and includes the starter battery cables. The Renogy 1000W and the Go Power! GP-SW3000-12 doesn’t come with cables, but hardly anyone will use them anyway, so this hardly gives the WZRELB 3000W an edge.

One advantage the WZRELB 3000W has over the GoWise PS1004 and especially the Go Power! GP-SW3000-12 is that it’s cheaper. For users that don’t mind the extra weight and loss of an AC outlet compared to the GoWise PS1004, the WZRELB 3000W is a somewhat cheaper alternative.

Pros

  • This device provides the same 3000 watts of power for a smaller price when compared to the GoWise PS1004 power inverter.
  • At 11.42 pounds, it’s just a hair lighter than sine wave inverters like the GoWise 2000W power inverter.
  • It has twice the AC power outlets the Renogy 1000W pure sine wave inverter offers.

Cons

  • It does weigh more than the GoWise PS10004 inverter.
  • It doesn’t offer a USB port as the GoWise 2000W power inverter does.
  • The standard one-year warranty is less than the one offered by the Voltworks 1500W power inverter.
  • It’s one AC power outlet shy of the GoWise PS1004 pure sine wave inverter.

Power Output & Battery Requirements

The output voltage comes in at a steady 2000 watts, with surge power peaking at 4000 watts. The Giandel 2200W comes in with a few more watts by comparison, with both devices being superior to modified sine wave inverters.

It runs off of a 12 battery or equivalent solar panels to generate enough of a charge. The only option on the list that is different is the WZRELB 3000W at 24 volts.

Outlets

This pure sine wave inverter boasts three AC power outlets. The only other devices with three AC outlets are the GoWise PS1004 and the Voltworks 1500W.

It comes with a single USB port which is fairly standard. Though the Voltworks 1500W comes with an extra. The Renogy 1000W and the Go Power! GP-SW3000-12 doesn’t have any USB ports by comparison.

Protection & Warranty

Like other power inverters, the GoWise 2000W comes with a full series of protective measures to guard against various problems. It also uses a replaceable 50 amp fuse similar to the Voltworks 1500W.

Like many other devices, it also comes with an alarm to indicate low voltage from the power source. The only one not to have this feature is the Giandel 2200W.

In the event of any problems, there is a standard one-year warranty on the device for repairs and replacements. For better warranties, users should consider getting the Giandel 2200W, Voltworks 1500W, BESTEK 300W, or the Go Power! GP-SW3000-12.

Dimensions

The GoWise 2000W power inverter is run of the mill in terms of sizing. Its durable aluminum casing measures 17.1 x 9.3 x 4, which is similar to the size of the Giandel 2200W or the Go Power! GP-SW3000-12.

It also weighs about 12 pounds which puts it above the WZRELB 3000W but just shy of the Giandel 2200W in terms of weight.

Other Product Notes

Like the other options on the list, the GoWise 2000W comes with the standard remote control and includes battery cables. The Renogy 1000W and Go Power! GP-SW3000-12 do not.

The GoWise 2000W is the cheapest in its class, with only the Voltworks 1500W, BESTEK 300W, and the Renogy 1000W. Strictly from a cost standpoint, this is the cheapest option that provides 2000 watts of power.

Pros

  • Three AC power outlets and a USB port make it as convenient to use as the GoWise PS1004 inverter.
  • A standard size and weight make it easy to install and use in most projects instead of the bulkier Go Power! GP-Sw3000-12 inverter.
  • The price is reasonable for what’s being offered in terms of warranty and wattage.

Cons

Giandel 2200W Pure Sine Wave Inverter

Giandel 2200W Pure Sine Wave InverterThe Giandel 2200W power inverter offers a bit more in terms of watts at the cost of a higher price tag. Some of the convenience is lost compared to others, but it does gain a better warranty than what is considered standard. All in all, it’s still an average pure sine wave inverter with a few subtle differences that might make it more appealing to some users.

Power Output & Battery Requirements

Unlike modified sine wave inverters, this device provides a steady flow of 2200 watts with peak power at about 4400 watts. This puts it above the GoWise 2000W by 200 watts of continuous power and 400 watts when comparing surge power.

It requires the standard 12-volt battery to operate. According to the manufacturers, one difference is that a 20A solar controller is included in the Giandel 2200W that sets it apart from the other options on the list. However,h this is only relevant if the user uses solar panels to achieve the output voltage.

Outlets

The Giandell 2200W is like most power inverters in that it offers two AC outlets. The GoWise 2000W, GoWise PS1004, and Voltworks 1500W come with an additional AC outlet.

There is also a single USB outlet for use with smart devices. The Voltworks 1500W has an extra USB port, and the WZRELB 3000W, Renogy 1000W, and Go Power! GP-SW3000-12 doesn’t have any by comparison.

Protection & Warranty

Like other pure sine wave inverters, the Giandel 2200W comes with all of the safety features out there. One major benefit to the Giandel 2200W over others is that it’s the only one with an auto-restart function. After a brief period of time, with no further issues, the device will turn itself back on, useful for momentary disruptions like power surges.

It also uses a replaceable 30 amp fuse. The only other devices with this feature are the GoWise 2000W, Voltworks 1500W, and the BESTEK 300W.

This device is unlike most standard power inverters in that it boasts an above-average warranty at 18 months for repairs and replacements. The BESTEK 300W has the same 18-month warranty and only the Voltworks 1500W or the Go Power! GP-SW3000-12 has higher warranties.

One difference from others on this list is that the Giandel 2200W does not alarm for low voltage. Any other option in this review would have this feature.

Dimensions

The aluminum alloy casing measures 15.7 x 9 x 3.5 inches. This makes it quite a bit smaller than the GoWise 2000W, which has a smaller voltage output.

It does weigh 12.91 pounds which makes it heavier than the GoWise 2000W. Even the WZRELB 300W and the GoWise PS1004 are smaller while offering more power output.

Other Product Notes

Once again, this product matches standard perks by offering remote control and includes battery cables. The only ones that don’t have the starter battery cables are the Renogy 1000W and the Go Power! GP-SW3000-12.

The Ginadel 2200W is expensive for offering 2200W. The WZRELB 3000W is a cheaper alternative while offering 800 more base watts. The GoWise 2000W is a much cheaper alternative while offering similar power capabilities.

Pros

Voltworks 1500W Pure Sine Wave Inverter

Voltworks 1500W Pure Sine Wave InverterThe Voltworks 1500W stands out amongst other pure sine wave inverters for offering a much longer warranty than what’s standard. It also has the largest number of outlets to provide for maximum convenience. It is expensive in terms of wattage compared to others, but it may be worth it for those who intend to use it frequently and want some peace of mind.

Power Output & Battery Requirements

The Voltworks 1500W offers 1500 watts of continuous power, unlike a modified sine wave inverter. This makes it one of the lower outputs on the list, with only the BESTEK 300W or the Renogy 1000W being lower.

It requires a 12-volt battery to provide the needed power supply just like any other device reviewed, except for the WZRELB 3000W, which needs a 24 volt.

Outlets

There are a total of five outlets across this device, making it the most of any option. There are three AC outlets similar to the GoWise PS1004 and the GoWise 2000W. It also has two USB ports, just like the BESTEK 300W.

Protection & Warranty

The Voltworks 1500W comes with the standard measure to protect against various electrical issues common in these devices. It also has a replaceable 50 amp fuse, also seen in the GoWise 2000W.

This product also stands out with an incredible 3-year warranty. This puts it far ahead of the standard one-year warranty options on the list. The only device that even comes close is the Go Power! GP-SW3000-12 with a two-year warranty.

Dimensions

The Voltworks 1500W aluminum casing comes in a fairly standard size measuring 14.6 x 8.15 x 3.48 inches. This makes it smaller than the Giandel 2200W but larger than the Renogy 1000W, which makes sense given it sits between the two in terms of power.

It weighs a light 8.69 pounds which is even smaller than the GoWise PS1004. The only devices that weigh less are the BESTEK 300W and the Renogy 1000W.

Other Product Notes

As is typical with power inverters on the market, it comes with remote control and battery cables.

The pricing also seems consistent with the Voltworks 1500W as it’s cheaper than the more powerful Giandel 2200W and more expensive than the Renogy 1000W. However, users can purchase the GoWise 2000W for an extra 500 watts of power for another ten dollars.

Pros

  • The three-year warranty is even higher than other above standard options like the BESTEK 300w.
  • With three AC outlets and two USB ports, it offers more than even the GoWise 2000W.
  • It’s very lightweight at 8.96 pounds, making it lighter than even the GoWise Ps1004.
  • It’s cheaper than the WZRELB 3000W.

BESTEK 300W Pure Sine Wave Inverter

BESTEK 300W Pure Sine Wave InverterThe BESTEK 300W is the ideal power pure sine wave inverter for those long days in the car or out camping. Unlike a less reliable modified sine wave inverter, this will easily power small electronics like tablets, smartphones, and laptops. It’s by far the most portable pure sine wave inverter on the list.

Power Output & Battery Requirements

It may not be much, but this 300-watt pure sine wave inverter will beat out even a slightly larger modified sine wave inverter. It’s at the bottom of the barrel compared to other pure sine wave inters on the list. The next one up is the Renogy 1000W that comes with 700 more watts.

Like other power inverters, it still requires a 12-volt battery or the same power supply level from solar panels.

Outlets

This little device still comes with two AC outlets like the bigger WZRELB 3000W, the Giandel 2200W, and the Go Power! GP-SW3000-12.

It stands out a bit thanks to having two USB ports. The only other device to have two as well is the Voltworks 1500W.

Protection & Warranty

The BESTEK 300W has all the same protections present in other inverters to protect against things like power surges. It even has a low voltage alarm that isn’t found on the Giandel 2200W.

It also uses the replaceable 40 amp fuse that devices like the GoWise 200W, Ginadel 2200W, and the Voltworks 1500W use. However, this is the only one to utilize 40 amp fuses specifically.

One significant downside is that the BESTEK 300W doesn’t have an LED screen like any other inverters on this list. Unlike the others, it does have a power indicator light, but the LED screen would be far more useful than a simple light in all reality.

It does slightly redeem itself with an above standard 18-month warranty similar to the Giandell 2200W. The only devices with better warranties are the Voltworks 1500W or the Go Power! GP-SW3000-12.

Dimensions

The BESTEK 300W is smaller than other pure sine wave inverters atsize  8.1 x 5.3 x 2.6 inchee. The next size up is the Renogy 1000W, and it’s almost twice the size.

It also weighs an incredibly lightweight 1.4 pounds which is a third the weight of the Renogy 1000W. It may not win in the power output or protections market, but it is easily the most portable pure sine wave inverter on this list.

Other Product Notes

The BESTEK 300W forgoes the traditional starter battery cables in favor of a cigarette lighter. It is the only inverter on the list to have the ability to plug into a cigarette lighter.

It is also the cheapest by far. The closest pricing is the Renogy 1000W, and it costs more than three times the amount of the BESTEK 300W.

Pros

  • Its small dimensions and size make it very portable, unlike the bulky and cumbersome Go Power! GP-SW3000-12.
  • A convenient cigarette lighter makes it easier to charge in the car than the Renogy 1000W.
  • The 18-month warranty is above the standard found on the GoWise 2000W.
  • It has more USB ports than the WZRELB 3000W.
  • It is by far the cheapest pure sine wave inverter on the list, less than a tenth of the Go Power! GP-SW3000-12.

Cons

  • With 300 watts, it’s very limited in running compared to even the Voltworks 1500W.
  • It only plugs into a cigarette lighter, limiting the functionality instead of connecting directly to the battery like the Renogy 1000W.
  • No LCD or LED display to indicate issues or performance like the one found on the Giandel 2200W.

Renogy 1000W Pure Sine Wave Inverter

Renogy 1000W Pure Sine Wave InverterThere aren’t many flash or perks that come with the Renogy 1000W pure sine wave inverter. It certainly can do the job it is built for, but it seems better suited to serve as something integrated into a camper or van. At the end of the day, it will still beat even the best-modified sine wave inverters when it comes to power electronics.

Power Output & Battery Requirements

Unlike a modified sine wave power inverter, the Renogy 1000W pure sine power inverter will hold a steady charge of 1000 watts with a peak of 2000. This makes it smaller in output than the Voltworks 1500W but more than the BESTEK 300W.

To accomplish this, it needs to be connected to a 12-volt battery or enough solar panels to provide the same power supply level as any of the other inverters.

A unique feature of the Renogy 1000W pure sine wave inverter is that it comes with an ECO power-saving mode to minimize the power draw. This may make it a more appealing option for some users than any other inverter on the list.

Outlets

The Renogy 1000W pure sine power inverter is unusual in that it only offers a single AC power outlet. All of the others have at least two, and the GoWise PS1004, GoWise 2000W, and the Volt works 1500W come with three.

It also doesn’t have any USB ports, though this is shared by the WZRELB 3000W or the GO Power! GP-SW3000-12. In terms of outlet options, the Renogy 1000W ranks at the bottom.

Protection & Warranty

This pure sine wave inverter is the latest protection for various electrical problems, just like the other inverters. It also has a low voltage alarm not present in the Giandel 2200W.

The Renogy 1000W comes with the standard one-year warranty found on most devices. Some users may prefer a better warranty like the Voltworks 1500W, which also comes with more power.

Dimensions

The Renogy 1000W aluminum casing is measured at 13.4 x 7.6 x 2.8 inches. This makes it just a little more compact than the Voltworks 1500W.

It does weigh lighter than usual at 6.42 pounds making it the second lightest option after the BESTEK 300W.

Other Product Notes

While it comes with the standard remote control present in most inverters, the Renogy 1000W’s is unique in that it can also be used to activate the ECO mode only seen in this device.

It also stands out for being one of the only inverters on the list not to have battery cables, and the other is the Go Power! GP-SW3000-12. While the BESTEK 300W also doesn’t have battery cables, it offsets this with a charger plugs into the cigarette lighter. Admittedly this shouldn’t be a deal-breaker as the starter battery cables that come with the other devices should be replaced with something better anyway.

While the Renogy 1000W is the second cheapest option, it isn’t much cheaper than the Voltworks 1500W. For fifty dollars, more users may consider upgrading for the extra 500 watts.

Pros

  • Unique ECO Mode lets it conserve power more efficiently than other devices like the Giandel 2200W.
  • At 6.42 pounds, it’s lighter than the Voltworks 1500W.
  • It’s the cheapest option aside from the BESTEK 300W while offering three times the watts.

Cons

  • 1000 watts may not be enough to run things that the more powerful Voltworks 1500W would be capable of.
  • One AC outlet is far less than the standard two that come on products like the Giandel 2200W.
  • There is no USB port.
  • The one-year warranty is low, especially compared to the Voltworks 1500w.
  • No cables are a minor issue, but it is standard to receive cables.

Go Power! GP-SW3000-12 Pure Sine Wave Inverter

Go Power! GP-SW3000-12 The Go Power! GP-SW3000-12 is a beast in terms of durability and performance. Unfortunately, that does come with a high price tag and a cumbersome product compared to others on the list. It’ll do the job, but it may not be appropriate for every situation.

Power Output & Battery Requirements

This power inverter boasts a 3000-watt output power with a 6000 peak potential. This puts it on par with the GoWise PS1004 and the WZRELB 3000W in terms of power.

It also requires the standard 12-volt battery required by everything that isn’t the WZRELB 3000W.

Outlets

The Go Power! GP-SW3000-12 comes with two AC outlets, just like the WZRELB 3000W or the Giandel 2200W. It does not come with a USB port. In terms of outlets, the GoWise PS1004 pure sine wave inverter has it beat on both fronts.

Protection & Warranty

This inverter comes with multiple protection systems present in the other pure sine wave inverters. It also stands apart from the Giandel 2200W in that it has a low voltage alarm.

It also has an above standard two-year warranty. The only better offering is the three-year warranty found on the Voltworks 1500W.

Dimensions

The Go Power! GP-SW3000-12 pure sine wave inverter is large, measuring at 17.8 x 6.5 x 8.2 inches, though this is smaller than the GoWise PS1004.

It does weigh a heavy 21 pounds despite its smaller size. The closest in terms of weight is the Giandel 2200W, and it’s still almost half that at 12.91 pounds.

Other Product Notes

Like others on the list, this pure sine wave inverter is capable of being controlled via remote. Unfortunately, the remote does not come with the product and must be purchased separately, an annoyance only present with this pure sine wave inverter.

Another unusual deviation is that it does not come with its own starter battery cables like the Renogy 1000W. Most users would want to replace these anyway, but, strangely, something standard wouldn’t be included with this pure sine wave inverter. Especially considering the price tag.

On that point, it is easily the most expensive pure sine wave inverter anyone can buy from this review. It is twice the price of the GoWise PS1004, and that was already considered expensive. With the less-than-standard offerings and the high price tag, the Go Power! GP-SW3000-12 ranks lowest compared to the other devices here.

Pros

  • 3000 watts should be more than capable of running just about anything the GoWise PS1004 could.
  • It comes with a two-year warranty making it better than even the Giandel 2200W with its 18-month warranty.

Buying Guide For Best Pure Sine Wave Inverter

Features To Look Out For Pure Sine Wave Inverter

Power Output

The basic responsibility of a pure sine wave inverter is to convert incoming DC power from a battery or solar system and convert it into useful AC power. Because of this, the types of devices and equipment used will dictate how much wattage is needed.

For instance, a refrigerator or an air conditioning unit will rely upon many watts to start and then stay running. Charging a smartphone or handheld speaker isn’t going to need nearly the same power output. So before anything else, future buyers should consider the power needs to dictate which pure sine wave inverter to look at. This is especially true when building a solar generator at h0me.

Here’s a rough idea of what each level of wattage can run:

  • 3000 watts – Large appliances like an air conditioner, water heater, or clothes dryer.
  • 2000 watts – Small appliances like coffee makers, microwaves, or blenders.
  • 1000 watts – Good for things like water pumps, televisions, and fans.
  • 300 watts – Small handheld devices like smartphones, speakers, and battery packs. Could run a single appliance like a fan or television by itself.

On a side note, in some cases, a modified sine wave inverter may be a cheaper alternative to powerless sensitive items like water pumps or phone chargers. But anything with delicate components, it’s almost always better to go with a pure sine wave inverter. There are other factors to consider, but generally speaking, this is the main difference between choosing a pure sine wave inverter vs. a modified one.

Outlets

Concerning the power output, the outlets are also an important factor to consider. Users will need many AC power outlets and possibly even a USB port to ensure they are usable and charge simultaneously.

Admittedly if the pure sine wave inverter is being installed in an RV or home, this is less of a priority as devices will plug into the outlets in the walls and not the power inverter. But if it’s a portable pure sine wave inverter or one that will provide power to just a few things without being wired in, then it is important to have enough outlets for the job.

It’s also important to note that just because a power inverter has multiple outlets doesn’t mean it can support multiple devices simultaneously. A 1000 watt inverter won’t run a microwave, a blender, and a radio simultaneously, even if it has three AC outlets.

Protection & Warranty

Having the right protection is important with a pure sine wave inverter as they are often used to charge sensitive electronics, which tend to be expensive to replace if something goes wrong. It’s standard for pure sine wave inverters to come with protections for things like overloading, short-circuiting, low voltage, reverse polarity, overheating, and other issues. Many will also have audible alarms to indicate low voltage.

When choosing the right, pure sine wave inverter, the warranty plays a big role as well. For users planning on something more intensive like connecting a power inverter into a solar-powered generator to charge home, having a longer warranty will be a high priority to ensure it lasts that long.

But if it’s something that will be installed in a camper that’s only used on vacations a few times a year, then having a smaller warranty may not be so bad. It’s also important to note that many of these devices have fused to protect against problems and may just need a new fuse instead of being entirely replaced through the warranty.

Dimensions

The size of the pure sine wave inverter will also be an important consideration, especially if installing in a camper, van, or RV where space availability is limited and weight is a concern. It might be better to downgrade if it’ll make a better fit or could necessitate some space alterations if a larger, more powerful device is needed. When installing a power inverter, keep in mind that it needs some space to breathe. The fans need room to run, and boxing the device in on all sides is asking for it to get overheated.

Other Product NotesOtherr elements of pure sine wave inverters may play into deciding which one to go with. Most come with remote control capabilities that allow them to be turned on or off from a distance to avoid accessing it directly. This can keep the device from running unnecessarily and be a major convenience if it’s located in a hard-to-access place in the home or RV.

Some of the newer model power inverters will have settings like an Eco Mode or automatic shutoff function. This can be a great way to avoid taxing the device and make it even more hands-off. LED and LCD options can also provide valuable information to indicate how well the device is performing, if the battery is low, or if the solar panels aren’t charging enough. It’s also helpful for diagnosing various problems that may arise.

Final Thoughts

No one size fits all when it comes to pure sine wave power inverters. Wattage requirements are the biggest factor and can range from something simple to charge a phone to something that keeps medical equipment on when the power goes out, and the backup generator kicks on.

Any power inverter should have full protection against any hazards that face electronic equipment. At the very least, surge protection and low voltage indicators are a must-have with any device.

Then finally, the price can have an impact on which device is chosen. Pure sine wave inverters aren’t cheap and can run a few hundred dollars. But when it comes to powering and protecting thousand-dollar laptops, power tools, appliances, smartphones, and other items with high price tags, it’s more than worth the cost. Still, it’s worth comparing and contrasting the different models and what they offer to ensure the right amount of money is spent on what’s needed for the intended project.
