Buyer’s Guide- What to Consider?
Choosing between best sine wave inverters may seem a difficult task unless you know certain factors behind them. Buying something that is affordable, efficient as well as upgraded is significant. Your electrical devices are mainly dependent on the power output of these inverters. Thus, you need to consider the different points given below before purchasing pure sine wave inverters.
1. Type of inverters
Inverters can be classified into various types on the basis of different characteristics. But, we take mainly two bases upon which inverters are divided into categories. On the basis of output, inverters can be classified as:
These are the ideal inverters to be used for residential purposes. This is because all of our electrical appliances such as microwave, TV, laptop, refrigerator, etc. are designed for the requirement of the sine wave. Sine wave inverters have a waveform voltage of sine wave that is much similar to the utility supply. Also, they are powered by rotating AC machinery. Although they are an expensive but suitable type of inverters for commercial and residential applications.
As the name suggests, they produce square waveforms. Plus, the usage of these inverters is very low as compared to others. If we connect sine wave appliances to square wave inverters, then they will get completely damaged. Very simple tools such as a universal motor can be connected with them.
They have a modified square waveform. We can also say that these fall under a mixture of sine and square waveforms. They can be connected to appliances like pumps, motors, fans, lights, etc. Basically, low powered devices are a perfect fit for them. But these modified sine wave inverters are noisy as compared to sine wave inverters. If you connect AC powered devices.
On the basis of the type of load, they can be classified as:
Generally, single-phase power is suitable for holding the commercial and residential load.
They are built to hold high industrial loads.
2. Power ratings
Power ratings of inverters vary between 50 to 50,000 watts. Bu these power ratings mainly depends upon surge ratings. This is why inverters come with both continuous and surge rating. You should check the inverter’s maximum surge protection. Well, it ranges from 20% up to 300%, but a standard surge rating is defined between 3 to 15 seconds. If your power requirement is 2000 then go for 2000 watt inverter. For most of the user power inverter 3000w pure sine wave capacity is enough and you can go for GoWISE Power PS1004 would be enough.
3. Battery size
The higher the number of battery size, the durable the inverter is. So, check the ‘ah’ value. It indicates as 100 mah, 150 mah, 180 mah, etc. Basically, ‘ah’ value tells us the extent of energy that a battery can store. Being other things equal, the battery size alone can rate down the performance of the inverter. Standard battery size is defined at 200 Ah. Thus, depending upon the number of devices you want to connect, choose the battery size accordingly. For inverter with high capacity battery you can go for Giandel 4000W Heavy Duty.
4. Volt Ampere ratings
VA ratings are compulsory as they determine the total voltage supplied to a group of appliances. You can also measure the VA rating for your inverter depending upon the power requirements of appliances. If you are considering to buy an inverter for home purposes, then simply divide the total power requirement by 0.8. The result is the VA that you need in your inverter. Generally, the power requirements for home are not more than 700 watts. In this case, VA ratings around 800-850 watts suit the best.
5. Additional protection
Pure sine wave inverters come with additional protection which also makes them popular among all. These exclusive features can be overheating, overload or overvoltage protection. While some inverters come with tag ‘surge protection devices’ or SPD. These all are necessary features in emergency situations.
You will find that most of the inverters are similar in features and design. Things that differ is the capacity. You do have to buy the most powerful inverter. Look at your requirements first and then choose the most suitable inverter for yourself. And if you stick to our list of top pure sine wave inverters, you will get the most tested and trustworthy inverters.
