What is a Solar Inverter and How Does it Work?

Whether you’re looking to get off the grid entirely or you have the peace of mind that comes with a backup power system, the role of a solar inverter cannot be overlooked. 

So, what is a solar inverter? How does a solar inverter work? You’ve come to the right place. We’re passionate about helping others live more sustainably and are eager to share insights into how a solar inverter can help you do just that with the insights awaiting you below.

An off-grid solar inverter harnesses the boundless energy of the sun, transforming it into a symphony of sustainable power for your home. It’s the cornerstone of modern, eco-conscious living. 

We aren’t just going to show you how a solar inverter works, though. You’ll also gain tips on choosing the right one here at OffGrid Living Solutions and setting it up to transform your lifestyle once and for all.

What is a Solar Inverter?

First things first - what is a solar inverter? As we touched on earlier, it’s a pivotal component in a solar power system. 

Its primary function is to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity. This conversion is crucial because AC is the standard form of electricity used in homes and businesses for powering appliances and electronic devices. 

The inverter's role extends beyond mere conversion though. It also manages the power flow, ensuring optimal performance of the solar panels, and often provides system diagnostics and connectivity features.

They often come equipped with Maximum Power Point Tracking (MPPT), which dynamically adjusts the voltage and current to extract the maximum possible power from the solar panels, adapting to variations in sunlight and temperature.

In conventional power grids, electricity generation is centralized and typically involves burning fossil fuels, which emit greenhouse gasses. Solar power, in contrast, is a decentralized and clean energy source. 

The solar inverter is a key differentiator here because it allows individuals and businesses to convert and use solar energy efficiently, promoting a shift from centralized, emission-heavy power generation to a cleaner, more sustainable model. 

This shift not only reduces the carbon footprint but also empowers consumers with energy independence, mitigating reliance on fluctuating fossil fuel markets and contributing to a more resilient power system. That being said, how does a solar inverter work exactly?

How Does a Solar Inverter Work?

The technical process of converting DC to AC is sophisticated. However, we’ll simplify it as much as we can to help you gain an understanding of what this intuitive device does to allow for a cleaner source of energy. So, how does a solar inverter work?

Converting DC to AC: Technical Process​​​​

Solar panels collect sunlight and convert it into DC electricity. This DC electricity, however, is not compatible with most home appliances and the grid, which operate on AC. The solar inverter steps in to convert this DC electricity into AC.

In simple terms, the inverter takes the constant DC output and changes it into a sine wave, mimicking the AC power typically supplied by the grid. 

This conversion involves several stages: the DC from the solar panels is first 'chopped' at a high frequency to create a pulse-width-modulated (PWM) signal. This signal is then filtered to produce a pure sine wave, which is the type of AC used in homes and businesses.

Solar Inverter Efficiency and Performance

The efficiency of a solar inverter is a measure of how effectively it can convert DC into AC. Most modern solar inverters have efficiencies between 95% to 98%, meaning that only a small fraction of the solar energy is lost during the conversion process. 

High-efficiency inverters ensure that maximum power is available for use, thus optimizing the overall performance of the solar power system.

Performance is also dependent on other factors, such as the quality of the components, environmental conditions (like temperature and shading), and the inverter’s ability to provide stable power under varying load conditions. 

Inverters with Maximum Power Point Tracking (MPPT) technology can adjust the voltage to maximize power output throughout the day, adapting to changes in sunlight intensity and panel temperature. 

Some inverters also come with advanced monitoring systems, allowing users to track performance in real-time and identify issues for maintenance. We’ll talk more about features like these ones later on when we discuss choosing the right system. 

Different Types of Solar Inverters

Solar inverters come in various types, each designed to suit different solar power systems and requirements. Understanding these types can help in selecting the right inverter for a specific solar installation.

Battery Inverters

Battery inverters are specifically designed for use in solar systems with energy storage. These inverters convert the DC electricity stored in batteries into AC electricity for use in your home or business. 

They are ideal for retrofitting a battery into an existing solar system or when you wish to keep the battery system separate from the solar panels. 

Battery inverters are crucial in systems where energy storage is a priority, ensuring that stored solar energy is readily available for use during peak demand times or when the sun isn't shining.

Central Inverters

Central inverters are large-scale inverters used primarily in commercial or utility-scale solar installations. These inverters can handle substantial power loads, typically in the range of hundreds of kilowatts to megawatts. 

They are characterized by their large, cabinet-like size and are designed for high-volume, high-efficiency solar power conversion. 

Central inverters are suitable for large solar farms or commercial installations where a significant amount of solar energy needs to be converted and managed.

Hybrid Inverters

Hybrid inverters, also known as multi-mode inverters, are designed to work with solar panels and batteries. They can manage energy from solar panels, store excess energy in batteries, and supply electricity to the grid or for local use. 

Hybrid inverters enable a seamless transition between these different modes of operation, making them an excellent choice for systems where energy independence and flexibility are essential. They are particularly useful in areas with variable electricity costs or frequent power outages.


Microinverters are small-scale inverters installed on each solar panel. Unlike traditional inverters that manage the output of multiple panels, microinverters optimize the performance of each individual panel. 

This is especially beneficial in situations where solar panels are subject to shading or orientation differences, as the performance of one panel does not affect the others. Microinverters enhance the overall efficiency of the solar system and provide more detailed monitoring of each panel's performance.

String Inverters

String inverters are the most common type of inverter used in residential solar installations. They are called 'string inverters' because a series or 'string' of solar panels is connected to them. 

These inverters convert the collective DC output of these panels into AC electricity. String inverters are a cost-effective and reliable choice for most standard residential solar systems. 

However, their efficiency can be affected by shading or panel orientation issues, as the output of the entire string is only as strong as the weakest panel in the string.

Quick Tips on Choosing the Right Solar Inverter and Getting it Set Up

Selecting the right solar inverter and ensuring its proper setup is a critical step in maximizing the efficiency and longevity of your solar power system. Here are some essential considerations to guide you through this process.

What Makes a Good Solar Inverter?

A good solar inverter should have a high conversion efficiency, meaning it can convert the majority of the DC power from the solar panels into AC power with minimal loss. Look for inverters with efficiency ratings of 95% or higher. 

Additionally, it should be durable and reliable, with a robust design to withstand environmental conditions. 

Features such as remote monitoring capabilities, easy maintenance, and compatibility with your solar panels are also important. 

Lastly, ensure that the inverter is certified and complies with local and international standards.

Selecting the Appropriate Size of a Solar Inverter

We cannot express the importance of proper solar inverter sizing highly enough. The size of the solar inverter should match the output of your solar panel system. 

A common rule is to choose an inverter with a capacity about 10-20% higher than the total peak output of your solar panels. This allows for potential expansion and ensures that the inverter can handle peak production on sunny days. 

However, an inverter that is too large can be less efficient and more expensive, so finding the right balance is key. This is something we can help you navigate through - so don’t hesitate to reach out.

Weatherproofing and Placement of Solar Inverters

Once you’ve actually chosen your inverter, it’s paramount that you set it up in the right place. Solar inverters should be installed in a location that protects them from extreme weather conditions, especially if they are not inherently weatherproof. 

Considerations include protection from direct sunlight, rain, and extreme temperatures. Some inverters may require a weatherproof enclosure if they are to be installed outdoors. The placement should also allow for easy access for maintenance and monitoring.

Monitoring and Control: The Solar Inverter Display

Modern solar inverters often come with a display or interface that allows you to monitor the system's performance. This can include real-time data on power output, energy consumption, and system efficiency. 

Some models offer remote monitoring through a smartphone app or web portal, enabling you to check your system's performance from anywhere. This feature is invaluable for maintaining the health of your system and optimizing its performance.

By considering these aspects, you can choose a solar inverter that not only meets your current needs but also offers flexibility and efficiency for future demands.
