Features of the Best Sine Wave Inverters

If you know what you are looking for, it isn’t that hard to get a great sine wave inverter that matches your needs. However, if this is your first time getting a sine wave inverter, there are some things that you will need to learn.

Enough Maximum and Continuous Power Loads

Remember that there is a difference between the maximum and continuous power loads. Start by making sure that the maximum power load is more than you estimate needing. Then, be sure to check that the continuous power capacity will work with the needs of your devices.

Proper Wattage Rating

The wattage rating of your pure sine wave inverter gives you an idea of what type of devices that the model works for. If you only need to charge cell phones, for example, anywhere around 50-watts should be enough. Larger appliances can typically require 2000-watts or more.

Safety and Protective Features

Using any sort of electrical device comes with an inherent risk. One small mistake can be dangerous. This is especially true for demanding devices such as pure sine wave inverters.

Make sure there overload protection features. This is one of the most basic things we find in each of the best pure sine wave inverters. Safety should always be a top concern of yours when you use potentially dangerous products like these.

Easy Interface and Use

Certain pure sine wave inverters are a lot easier to use than others. For example, certain models have an LCD display which gives you a lot more information and overall easier experience.

Many people can encounter a learning curve when they get their first pure sine wave inverter. In order to make things easier on yourself, make sure that you have a general understanding of the interface and how to use the device in advance.

Long Enough Battery Life

Make sure that you know how long your battery will last before you make a purchasing decision. It is common for people to encounter issues with battery life. If you want the best possible experience, a model like the Samlex Solar PST-300-12 is ideal since it has the ability to hold solar charges.

Most Common Issues People Have with Pure Sine Wave Inverters

• Low Wattage: When using a pure sine wave inverter, it is important that the device matches the watt rating that you need. If you don’t have enough maximum power, you might not be able to use the device as you expected to in the first place.
• Low Continuous Load: Maximum power specifications are often seen as a reflection of what the device is capability on a continuous basis. Continuous power levels are usually not the same as the maximum power, and a pure sine wave inverter won’t operate on maximum power all the time.
• Long Charging: The big battery that your pure sine wave inverter uses need to be recharged if you expect to you use it for the long-term. Make sure the charging length and capabilities match your expectations so you don’t get let down later down the road.

Before Buying a Pure Sine Wave Inverter

A power inverter is basically a device that is specifically designed to convert current from direct current (DC) to alternating current (AC). So, what about a pure sine wave inverter?

Simply put, the modified pure sine wave inverters will convert direct current to a form that is friendly to the various AC gadgets and appliances you would like to plug in.

A good example of a pure sine wave current is the standard utility electricity you tap from the grid. While a conventional inverter will give you an AC output, when connected to a DC power source, the output waves may not be safe for your valuable gadgets.

1 Overload Protection Features

When dealing with any power source, precaution should be exercised. As such, it is advisable to buy an inverter that has the necessary safety features. Overload protection is one of the most important features, in this regard. Unfortunately, this feature is not available in most of the affordable units in the market.

Although you may be looking forward to saving a few bucks on the purchase, the cheapest pure sine wave inverter is not the way to go. Without overload protection, your inverter will just blow up if a higher powered appliance is connected to it.

Most of the leading products in the industry feature overload protection. As such, the unit will adapt when a too high powered device is connected.

2. Continuous and Peak Loads

This is another aspect you need to be very careful about when shopping for the best pure sine wave inverter. First things first, the peak load of a power inverter is not the same as its continuous load. The peak load is the maximum load the unit can handle.

However, you need to understand that an inverter cannot function at peak loads. As a matter of fact, the leading products can only support the peak load for a few seconds. The continuous load, on the other hand, is the load the product can support and still function normally. Again, this boils back to the type of devices and electronics you will be connecting to the inverter.

3. Additional Features

While the above mentioned considerations are mandatory, the right features to have on your inverter will depend on your own preferences. Modern pure sine wave inverters are packed with a multitude of convenience and aesthetic features. You really do not need all of them. Here are some you may need to consider. Though:

• Display – An LCD display makes the inverter easier to operate and interpret. However, this feature will also affect the pricing of the inverter. This is why most of the affordable options do not have an LCD display.
• Air compressor – Some modern pure sine wave inverters have a built-in compressor. This is particularly beneficial if you intend to use the inverter on your car battery. As such, you may use the compressor to pump the tires. You will not need this feature if you will be using the inverter on your solar power system.
• Solar Charging Support – Though designed to run on almost any DC power source, not all inverters allow for solar charging. If you need an inverter for your solar power system at home, you need to buy a model that supports solar panel charging.

Ready To Buy The Best Pure Sine Wave Inverter?

Regardless of the intended application, the choice of the right inverter does not have to be a hard one. As a matter of fact, you do not to be an expert in the field for you to choose a pure sine wave inverter. Basically, you just have to get a unit if the right wattage and suitable peak and continuous loads.

Other than that, you should ensure that the product has the right safety features. It does not matter what features you are looking for, this guide will help you choose the best pure sine wave inverter.
