The Definition of an Inverter for Dummies

What is an electrical inverter, and how does inverter systems work? In simple terms, an inverter is a device that takes direct current (DC) and converts it into alternating current (AC).

For beginners, understanding how inverter systems work can be simplified by knowing that they convert 12 volts of direct current (DC) into 120 volts (or 230V for South Africa) of alternating current (AC). This allows how to use a power inverter you to power household devices and electronics when you’re on the go. AC voltage is what we typically find in electrical outlets, and it’s what powers our homes and most of our appliances. So, what does a power inverter do? Well, it bridges the gap between these two types of electricity, allowing you to use DC power sources, like a car battery or solar panels, to run devices that require AC power. The inverter systems and their ability to switch between DC and AC makes them incredibly useful, especially when you’re on the go and need to power your gadgets or appliances.

The inverter will then supply your house or building with alternating current. The output voltage, input voltage, frequency, and power depend on the inverter design. They also depend on the circuitry of your inverter systems. The type of inverter and how an inverter work in detail will be discussed later on in this article.

How does an inverter work?

An inverter is a fundamental component in various applications, including solar power systems, backup power supplies, and more.

Here’s how an inverter system work:

1. Conversion Process:

The primary function of an inverter is to transform the DC electricity supplied by sources like batteries, solar panels, or fuel cells into the AC electricity used by most household appliances and devices. This process involves changing the direction of current flow and altering the voltage to generate a sinusoidal AC waveform.

2. DC-to-AC Conversion:

The inverter’s main circuitry consists of electronic components, including transistors or insulated gate bipolar transistors (IGBTs), capacitors, and control circuitry. These components work together to rapidly switch the direction of current flow, creating an oscillating voltage that produces an AC waveform.

3. Pulse Width Modulation (PWM):

Modern inverters often use a technique called Pulse Width Modulation (PWM) to generate the AC waveform. PWM involves switching the transistors on and off in a rapid sequence, varying the width of the pulses. By adjusting the pulse width, the inverter can control the magnitude of the output voltage.

4. Sine Wave Generation:

Inverters aim to produce an AC waveform that closely resembles a sinusoidal waveform, which is the standard form of AC power from the grid. This is essential for compatibility with appliances and devices that require a stable and consistent AC supply. In high-quality inverters, the PWM technique is used to approximate a pure sine wave output.

5. Control Circuitry:

The inverter’s control circuitry plays a crucial role in regulating the output voltage and frequency. It ensures that the AC waveform generated by the inverter matches the specifications required for safe and effective operation of connected devices.

6. Output Filtering:

After the waveform is generated, output filtering components such as capacitors and inductors help smooth out any fluctuations and harmonics in the AC output. This filtering ensures that the AC power provided by the inverter is of high quality and free from unwanted noise or distortions.

Overall, inverters play a pivotal role in enabling the utilization of DC power sources for a wide range of AC-based applications, contributing to efficient energy conversion and distribution.

How to use a power inverter

Now that we know how an inverter works, let’s briefly discuss how to use a power inverter.

1. Grid-Tied Inverter Systems

Grid tied inverter systems are inverters connected to the power utility. They need power from the electrical grid to function. We use grid-tied inverters to lower our power consumption and the amounts of energy consumed during off-peak periods.

During a power outage, your grid tied inverter shuts down. It isn’t useful as a backup for load shedding. You either need a separate battery backup system, or you will need a generator for power.

Large commercial plants use grid-tied inverters. Commercial plants use the bulk of their power during the day. Grid-tied inverters can reduce the cost of power significantly. The reason is that grid-tied systems produce power during peak periods.

We recommend you get a detailed analysis of your power consumption. What capacity per day do you consume? Do this before investing in a grid-tied system. A detailed report with a breakdown of hours, days, and maximum peak consumption is ideal. It will give you a clear sign of what inverter is best for your individual needs.

Why a Grid-Tied Inverter Is Not Ideal as a Home Backup System in South Africa

Grid-tied systems are not ideal applications for home use in South Africa. The reason is that most South African homes’ consumption is less during daytime hours. Grid-tied inverters don’t store power. This makes them cheaper than off-grid and hybrid inverter options.

2. Off-Grid Inverter systems

Off-grid inverter systems work independently from the utility. They supply power to charge the batteries of a battery inverter system.

Off-grid inverters fulfil the demand of the load to maintain loads in poor weather. They also supply the demand for night time consumption. An inverter home back-up system off the grid works well where there is no power from the utility.

Off-grid systems are also perfect where the demand for power is less. They are often more costly per KW than your grid-tied inverters. The reason for the higher price is that longer periods of runtime need more storage.

They are also to maintain the solar batteries and supply your battery bank. If you need additional power when the mains power is out, these types of inverters are ideal, although pricier.

3. Hybrid Inverter Systems

A hybrid inverter systems are a brilliant choice for the average household. A hybrid inverter is perfect for users looking for a self-sufficient solar and battery option. This you can do without disconnecting completely from the grid.

For households that don’t have too many blackouts, a hybrid inverter is the perfect solution. It can help you with a backup power source when there is a blackout or power failure. But it also connects to the grid when the power supply is stable. It’s the best of both worlds.
