Disadvantages of pure sine wave inverters

How to Pick the best pure sine wave inverter with automatic transfer switch

The best thing about pure sine wave inverters is that they convert the DC from the batteries to AC, which is almost similar to what you get through the grid system. The current is palatable for refrigerators, laptops, and sound systems.

No doubt, there are several pure sine wave inverter models on the market. However, you cannot always take the claims of various manufacturers at face value. The following factors will help you get more bang for the buck.

Function

The primary function of power inverters is to convert electrical energy from direct current to alternating current. They come in an extensive variety of options and power functions, depending on your needs.

For example, you can get a power inverter to back up a building in case of an outage or powering a car radio. What do you want the inverter to do for you?

Output Size

Ideally, the size of the pure sine wave inverter should be a tad higher depending on the usage or output requirements. The first step is usually to figure out the power requirements and then add 15% of the total to accommodate the overhead. Here, we are talking about continuous wattage.

The Efficiency of the Inverter

Inverters will have different efficiencies depending on the model and brand. The conversion of the current will generate heat, and some power will be lost in the process.

For example, you may lose up to 10% of the battery power, or even more. What matters is the efficiency gap of the inverter. So, what can you do to get the most efficient inverter?

One thing you can do is take the specifications, and of course, the reviews from other users. Or remember to turn the inverter off when not in use.

Battery Power

The battery power is another critical consideration. Well, it makes no sense to get an excessively high wattage inverter well you only require a few hundred amps.

You would be dealing with a case of drained battery if that were to happen. No doubt, pure sine wave inverters cost a pretty penny, and you must get the right one.

The best pure sine wave inverter with an automatic transfer switch is always worth the cost that you pay. The excellent quality sine wave inverter is efficient, and versatile in that you can use it on a wide variety of equipment, and protective for your equipment.

Don’t take a chance with your sensitive electronic equipment such as laptops and refrigerators, among others.
