How to Buy the Best 24 Volt Inverters?

05/03/2022

Dabbling into solar energy means sorting out all the elements that will make up your whole solar setup. You’ve read and learned all about the essence of this renewable energy, solar panels. Now, it’s time to move on to the next component of your solar system: inverters. Since there’s a lot to consider, we’ve put together this 24V Inverter Buyers Guide to help you at each stage of the buying process. 

24V inverters are less common than 12V inverters, and most people choose them when they have to power appliances of over 3000 Watts with their solar system. As you read this 24 Volt Inverter Buyers Guide, you’ll understand the basics of 24V inverters, their best uses, what role they play in your system, and relevant considerations in the purchasing process.  

24v Solar Inverter Basics

The first thing you need to know before purchasing an inverter is what they are and what they do. 

A power inverter is a device that converts low-voltage DC (direct current) to standard household AC (alternating current) power. This energy conversion allows you to use electricity for powering everyday appliances. Inverters don’t produce energy on their own. They draw energy from other electrical sources producing DC, such as batteries or solar panels. The DC power source needs to provide enough voltage to meet the energy demands of the appliances. 

Like solar panels, inverters have different voltage and wattage ratings. The inverter’s input voltage varies according to the design. Nonetheless, 12, 24, and 48 volts are the most common options. 12-volt inverters are commonly used in small systems, like RVs, whereas 24 and 48 Volts inverters are a popular choice for home energy systems.

Types Of Solar Inverters

There are mainly two types of solar inverters: pure sine wave and modified sine wave inverters. 

Pure Sine Wave Inverter

Pure sine wave inverters produce the same power as utility companies. Their output voltage comes in the form of sine waves, a very harmonic and smooth waveform with little distortion. Since the current rises and falls smoothly below zero, they are perfect for running the most sensitive electronics. Pure sine wave inverters are more expensive, and homeowners typically combine them with modified sine waves inverters in a large solar system. 

Modified Sine Wave Inverter

Modified sine wave inverters are more affordable and less efficient. Still, they are the most common among home solar systems. Modified sine waves inverters also produce power waves. The main difference is that the current takes the form of a square, abrupt wave. You can power most of the electronic devices with modified sine wave inverters. However, they’re not ideal for running delicate appliances that require a smooth and clean current.

How To Buy A Solar Inverter

In this section, you’ll find explanations of the essential aspects you have to consider when purchasing an inverter.

How Many Outlets Do You Need?

How many outlets you need depends on how many appliances you want to run off the inverter. Most inverters come with dual AC outlets, but there are inverters with up to four outlets. Some inverters also come with USB outlets to avoid using adaptors and large plugs to charge cell phones. 

If the inverter’s inbuilt outlets aren’t enough, you can always plug in a power strip to your inverter output receptacle, and then plug the various devices into the power strip.

Noise

It’s normal for inverters to make a certain amount of noise. In most cases, it is the internal cooling fans preventing heat buildup. You can also expect higher noise when inverters are sustaining a high output for long periods of time. Still, most high-quality inverters are usually very quiet, and their noise is tolerable. 

If the noise level is a primary concern for you, you can check your inverter’s noise level in the datasheet to ensure it will be silent. Also, you should install your inverter far away from bedroom windows or places where you spend lots of time. 

Modified sine wave inverters can make a vibrating, humming noise when connected to certain appliances or devices, like computers or hair dryers.
