Best Pure Sine Wave Inverter Reviews | You Can Buy In 2019
There are two places where inverters will be of use—which is indoor and outdoor.
The former is straightforward, in a way that you might have an emergency and the inverter comes handy. On the other hand, the latter is a bit direr since you're not in the comfort of your home.
You might be outdoor camping or even mountain climbing. And there are a lot of issues that are prevalent in any of those situations.
Fortunately, most of them (the norm like food, tents, flashlights, and weather resistant wears) would have been handled, but still, there usually remains a major one.
That is electricity. You have to provide power for your time outdoors—and though, some just use a power bank, it'll eventually run out.
Therefore, the perfect choice in this particular situation is an inverter. It is easy to set up and best of all,it is budget-friendly and reliable. You just have to select one, which the following teaches you how to do.

What Is A Pure Sine Wave Inverter
A Pure sine Inverter is a device or circuitry that changes direct current to alternating current that is DC to AC power in such a way that the voltage rises and falls smoothly with a smoothly changing phase angle and also changes its polarity instantly when it crosses 0 Volts.
Things to Consider Before Buying an Inverter
These are the factors you have to take into consideration before buying an inverter.
What's the Duration of Your Stay?
For outdoor applications, it wouldn't do to opt for an inverter whose capacity is small when your trip will last for a while. Likewise, this goes both ways—wherein, if you don't see yourself using that much time outdoor (ever), you don't need to purchase anything extravagant.
On the other hand, do keep in mind that a little bit more power wouldn't hurt especially if you're planning to use it at home. Still,we digress; it's far more economical to save money where ever you can since you might not even use the inverter to its full potential.
Does it have the Needed Safety Features?
As a matter of fact, the inverter you want to purchase must (not should) have the necessary features for safety. Obviously, this helps in the prevention of unsavory situations that anybody would rather avoid.
Your next inverter purchase must come with an auto reset feature, audio alarm for notifications, and circuit protector for protection from overheating or overload.
What is the Inverter Going to Power?
Just because your duration is short doesn't mean the consumption won't be high. This is the reason why the types of equipment that the inverter is going to power play a big role in the selection process.
If you're using devices like refrigerators and heaters, obviously, the consumption rate will be high. But if you only need to charge your phone and laptop, you might have to cut down on the battery capacity that you choose.
The Type of Battery
This directly connects to how much power you personally want. That said, there are 3 different types of batteries that you can choose for your inverter: The lead acid batteries, tubular batteries, and maintenance free batteries.
The first needs occasional maintenance to function efficiently and you need to refill the electrolytes regularly.
The second one is far better at power consumption and doesn't need much maintenance.
Finally, the last one needs no maintenance as the name sounds. They're also more expensive than the others, charge faster, offer more power, and are overall better.
The inverter that you buy, make sure it comes from a reputable company with services that can handle mostly any issue you might have. Also, warranty (its length and terms) is another factor that the company should be able to easily process.
Pure Sine Wave vs. Modified Sine Wave – Why Pure Sine Wave is Better?
With the above being a combination of pure sine wave and modified sine wave inverters, there is a particular reason why the former have a higher number on the list.
That reason, simply put, is safety. Certain devices with AC motors such as;
Will never fully run off of a modified sine wave inverter. As a matter of fact, some will not even work, and the ones that do work will generate a lot of heat while will lead to circuit failures.
The cause of all of this is pretty straightforward. Modified sine wave inverters have higher total harmonic distortion (THD), which forces the above appliances to generate a lot of heat.
This is as opposed to pure sine wave inverters, that have lower total harmonic distortion and thus, generate less heat (like a lot).
Nonetheless, modified sine wave inverters do come at a cheaper price than the pure sine wave inverters. But for full access to all devices with complete safety ensured, a pure sine wave inverter is unbeatable.
How to Size Your Pure Sine Wave Inverter
A good pure sine wave inverter should have enough capacity to power the devices you have. If you use only one device that's easy to get your desired inverter. But it is tough to determine when you use more than one device. Don't your you just need to calculate the total consumption.
Notice on your device that how much wattage your device need to run. You will get it somewhere on your device. You may get voltage and amperage ratings instead. Use this equation to get your watt.
Amps x Volts = Watts
Your inverter >= Total (Watts) x 1.2
After getting the wattages of your devices you will add them together. Well, this number will be the smallest pure sine wave inverter that could possibly suit your needs. Now you need to add between 10 and 20 percent on top and then buy a pure sine wave inverter that size or larger.
The other factor to keep in mind when determining the necessary size of a pure sine wave inverter is the difference between Running Watts and Starting Watts.
Starting Watts is the wattage that a pure sine wave inverter can supply for short periods of time when the demand spikes, while Running Watts is the limit for normal operation. If your electric device needs 1000 watts, then you need a pure sine wave inverter that has a running watts rating of 1000 watts.
User Guidelines for Using Any Inverter
1. Use the Standard Battery Cables Packaged with the Inverter
This should be done in order to avoid errors or issues that you might otherwise face if you're using cables not tailored to handle the inverter's power flow.
2. Make Sure not to Overload Your Inverter
Regardless of the type of device you're using, do not load too much on the inverter. For example, if you want to use a fridge that'll take “X” amount of power, make sure you use an inverter with “3X” to “5X” continuous power. Likewise, the cumulative demand for a variety of devices should be calculated before you'll load them on the inverter.
3. Turn the Load Off Before the Inverter After Every Use
With the inverter powering your fridges, heaters, and computers, you must always switch them off first before turning the inverter itself off. By doing this, you avoid unwanted complications that might otherwise leave your appliances/devices in poor conditions.
Note: This also applies when turning on your inverter. Always turn off the load (fridges and computers), before you start using it.
4. Avoid Direct Sunlight
To promote your inverter's lifespan, you should always avoid it having direct contact with sunlight. Instead, keep it in a cool, but dry environmental to enhance its lifespan and performance.
5. Avoid Certain Unhealthy Connections
Like the above, to maintain the inverter's lifespan and to also avoid certain scenarios, never connect the inverter to the grid power and also never switch the connection terminals (negative and positive pole).
Provided that you want to select an inverter (not excluding modified sine wave inverters), we've included most of the factors that you have to take into consideration before purchasing one.
Alternatively, if the time and effort don't appeal to you, then you can go through the 5 inverters above, and pick anyone that you prefer the most.
