A pure sine wave inverter is essential if you want to power sensitive electronic devices using a DC power source. Sensitive electronic devices such as TV, laptops, and chargers cannot tolerate the distortion in the sine wave. The distortion can damage the appliance, so you need a pure sine wave to run such appliances. The only way to convert DC into a pure sine wave is by using a pure sine wave inverter. If you live off-grid or in an RV, then you need a pure sine wave inverter to power appliances.
Pure sine wave inverters provide safe power to appliances. Their distortion is very low, and the wave is almost like a pure sine wave. If you are looking for the best pure sine wave inverter, then you are in the right place. Today, we are going to discuss how you can select the best pure sine wave inverter. We will explain every term and important aspects. Moreover, we have also selected some of the best products that could solve your problems. So, stay with us.
How to Choose the Best Pure Sine Wave Inverter?
Choosing the best pure sine wave inverter is not an easy task. Not everyone is familiar with the terms, features, and functions. If you want to select an inverter according to your needs, then you need to understand everything about pure sine wave inverters. Therefore, we are going to discuss some critical aspects that you need to consider while buying a pure sine wave inverter. Let’s start the discussion.
The continuous power of a pure sine wave inverter shows the maximum power that the inverter can provide consistently. It’s continuous power, so you can expect to get this power continuously from the inverter. You can connect appliances, but the sum of the powers of appliances connected to the inverter should be less than or equal to the continuous power. For instance, if the inverter is rated at 1000W continuous power, then you can connect an appliance of 1000W or multiple appliances, but the power consumption should not be more than 1000W.
It is necessary to see this rating and get the inverter according to your needs. If you want to power an appliance that is rated at 1800W, then you need to get an inverter that has continuous power more than 1800W. Some inverters can bear a little more load than their rated continuous power, but it’s an exceptional case.
Peak Power/Surge Power
Peak power is the power that the inverter can provide for a short period of time. Some devices or electrical machines (such as a motor) take more power at the start. They draw more current, which is just for a few seconds. This is often known as surge current. For example, if the motor is rated at 1000 continuous watts, then it will take more power at the start. Thus, inverters have the capability to provide this surge power or peak power to start the appliance. If the inverter is unable to provide the peak power, then the appliance will not start. This is the second most important thing that you need to consider.
An inverter is an electrical device, so there can be any fault due to an unusual/abnormal condition. Any unusual condition can damage the inverter. So, there are protection features to protect it. Every inverter should have these protection features. The most common protections that you will find in almost all inverters are high/low voltage protection, overheating protection, and overload protection. Furthermore, there are usually one or two fans to prevent overheating.
If you connect the terminal in the opposite polarity, then it will damage the inverter. So, you need to be careful. But some inverters have reverse polarity protection, which keeps the inverter safe, even if you have connected the terminals in the wrong way.
Inverters have power outlets where you can connect the devices. All pure sine wave inverters have AC receptacles that can power AC appliances. There are commonly two or three AC receptacles. In some inverters, you will find a 5V USB port, which can be used to charge mobile phones, power banks, and other devices that require 5V DC.
Total Harmonic Distortion (THD)
Inverters convert DC into AC. While converting the DC into AC sine wave, there is a distortion in the wave. This distortion cannot be eliminated, and 100% pure AC sine wave is not achievable from the current technologies of inverters. Thus, the distortion should be as low as possible. A pure sine wave has only one frequency because it does not contain the harmonics that create distortion. The amount of distortion is represented as THD, which is a percentage. The THD of a pure sine wave inverter should be lower than 3%. If the THD is too high, then it will damage sensitive electronic appliances.
Some inverters can be controlled via remote. This is an excellent feature that allows you to control the inverter from a distance and keep the inverter away. The remote controller is usually wired.
This is an excellent pure sine wave power inverter that really provides a pure sine wave. The output wave has a very low total harmonic distortion, which is lower than 3%.
