The Importance of Inverters In South African Households

In South African households, where electricity supply can be unpredictable and subject to frequent disruptions, inverters play a crucial role in ensuring a continuous and reliable power source. With load shedding and power outages being common occurrences, having an inverter becomes essential for uninterrupted daily activities. Inverters provide the ability to switch seamlessly between grid power and battery backup, allowing households to keep essential appliances and devices running during blackouts. Moreover, inverters enable households to optimize their energy consumption by storing excess power generated from renewable sources like solar panels. By reducing reliance on the grid and embracing alternative energy solutions, inverters contribute to greater energy independence, cost savings, and a more sustainable future for South African households.

Understanding inverters

What is an Inverter?

An inverter is an electronic device that serves the purpose of converting direct current (DC) electricity into alternating current (AC) electricity. This conversion is essential because most household appliances and devices operate on AC power. Inverters enable the use of AC-powered equipment even when the available power source is DC, such as batteries or solar panels. They accomplish this by taking the DC input and electronically transforming it into a stable and regulated AC output. Inverters play a vital role in various applications, including residential, commercial, and industrial settings. They provide a reliable and efficient means of utilizing electricity from diverse sources, ensuring that appliances and devices can be powered seamlessly and efficiently. Whether it’s during power outages, off-grid living, or the integration of renewable energy systems, inverters serve as the backbone of modern energy management, enabling us to make the most of our electrical devices and systems.

What is the difference between Solar and Inverters?

Not much! They’re two components in one system. Solar panels capture sunlight and convert it into electricity, like a generator that runs on sunlight instead of fuel. This electricity generated by solar panels is in a different form called direct current (DC). However, most of our household appliances and devices use a different type of electricity called alternating current (AC). Here’s where inverters come in. They take the DC electricity produced by solar panels and convert it into AC electricity, which is what our appliances need to work. In other words, solar panels generate the power, and inverters make that power usable for our everyday needs. Together, solar panels and inverters create a seamless system that harnesses solar energy and transforms it into electricity we can use in our homes and businesses.

What is the difference between an inverter and a UPS?

An inverter and an uninterruptible power supply (UPS) are two distinct devices that serve different purposes when it comes to power backup. An inverter converts DC (direct current) electricity from a battery or another DC source into AC (alternating current) electricity, which is what most appliances and devices in our homes use. It ensures that when the main power supply goes out, the inverter kicks in and provides power from the battery, allowing us to continue using our devices. On the other hand, a UPS is a combination of a battery and an inverter. It not only converts DC to AC but also constantly charges its battery using the main power supply. So, when there is a power outage, the UPS seamlessly switches to battery power without any interruption. In simpler terms, an inverter is like a backup generator that only turns on when needed, while a UPS is like a generator that is always ready to provide power instantly during an outage, ensuring uninterrupted operation of our devices and protecting them from power surges or fluctuations.

Typically in household applications, inverters are used to power the entire house, or a large portion of it. And UPS’s are used to power one or very few appliances (like a TV, Computer or Wifi Modem).

Does an inverter need electricity?

Yes, an inverter needs electricity to function properly. However, it’s important to understand that an inverter doesn’t generate electricity on its own. Instead, it requires a power source such as batteries or solar panels that provide the initial DC (direct current) electricity. The inverter then takes this DC electricity and converts it into AC (alternating current) electricity, which is what our appliances and devices use. So, while an inverter itself doesn’t need electricity, it relies on a separate power source to provide the initial DC power that it can convert into usable AC power. This is why inverters are often used in conjunction with batteries or solar panels to ensure a constant and reliable supply of electricity, even during power outages or in off-grid situations.


Why do I need an inverter in my house?

In South Africa, we often experience load shedding, which means the power goes off for a while. That’s where an inverter becomes super handy. It’s like having a secret power source in your house. When the lights go out, the inverter jumps into action and gives you electricity from batteries or other sources. You can keep your lights on, use your appliances, and stay connected even when the rest of the neighborhood is in the dark. It’s like having your own mini power station, just for you! So, having an inverter in your house is a smart move, especially in South Africa with all the load shedding. It helps you stay powered up and avoid the frustration of being stuck without electricity. It’s like having a magic trick up your sleeve that saves the day when the power company lets us down.

Choosing the Right Inverter

Determining what size inverter you need to run your house is actually pretty straightforward. Here’s how you can figure it out in simple terms. Take a look at the appliances and devices you want to use during a power outage. Check their power ratings, which you can usually find on a label or in the user manual. Add up the power ratings of all the things you want to run at the same time. This gives you an idea of how much power you’ll need. Then, look for an inverter that can handle that total power requirement. Make sure to choose an inverter with a capacity a little higher than what you calculated to be on the safe side. It’s like picking a backpack that can carry all your stuff and a little extra. So, by adding up the power needs of your appliances and choosing an inverter with enough capacity, you’ll have the right size to keep your house powered up during a blackout.

Factors to consider when selecting an inverter to run specific appliances

Running a television: What size inverter do you need?

If you want to run a television using an inverter, you’ll need to consider the power requirements of your TV. Firstly, look for the power rating, which is usually mentioned on a label located at the back of your TV, or in the user manual. It’s usually in watts (W) or sometimes in volts (V) and amps (A). Once you have that information, you can choose an inverter that can handle that power requirement. For example, if your TV needs 200 watts of power, you’ll want to get an inverter that can handle a little more than 200W. By checking the power requirements of your TV and choosing an inverter that can provide enough power, you’ll be all set to enjoy your television even when the lights go out.

Powering a refrigerator: Calculating the right inverter size

When it comes to powering a refrigerator with an inverter, you’ll need to consider its power requirements, especially its startup power. First check the label on the refrigerator or its user manual to find its power rating. This rating is usually given in watts (W). Once you have that information, you’ll want to choose an inverter that can handle at least 20% more then what’s listed. This is because the startup power needed by your refrigerator is greater than its running power. Having an inverter that can match the startup power requirements of your refrigerator, you can ensure that it has enough power to keep your fridge running smoothly during a power outage.

Battery Considerations

How many batteries are needed for an inverter?

The number of batteries needed for an inverter depends on the power requirements of the devices you want to run and how long you want them to run. In simple terms, think of batteries as fuel tanks that store electricity. The more power you need and the longer you want to use it, the more batteries you’ll need. To determine the number of batteries, consider the capacity of each battery (usually measured in ampere-hours, or Ah) and the voltage required by your inverter. Divide the total power requirement by the battery capacity to get an estimate of the number of batteries needed. It’s like figuring out how many gas cans you need to fill up your car for a long road trip. Keep in mind that using larger batteries or connecting batteries in parallel can increase the overall capacity. So, by considering your power needs and the capacity of batteries, you can determine the right number of batteries for your inverter setup.

How many hours does an inverter battery last?

The number of hours an inverter battery lasts before needing to be recharged depends on two main things, the capacity of the battery and the power consumption of the devices connected to the inverter.

The capacity of the battery is typically measured in ampere-hours (Ah). So, if you have a 100Ah battery and your devices draw a total of 10 amps, the battery will last approximately 10 hours (100Ah divided by 10 amps) before it needs to be recharged. Keep in mind we do not recommend using 100% of your battery capacity as it will shorten its life cycle. These calculations are a rough estimate and can vary based on factors like battery age, efficiency, and any other power losses in the system. So, it’s important to consider both the battery capacity and the power consumption of your devices to get a general idea of how long the battery will last before requiring a recharge.

What is the lifespan of an inverter battery?

Estimating the lifespan of an inverter battery is like guessing how long a toy will last before its batteries run out. It depends on a few factors. Firstly, the quality of the battery plays a role. Higher-quality batteries tend to last longer. Secondly, how often you use the battery and how much power you draw from it affects its lifespan. The more you use it and the more power you take out, the shorter the battery life. Lastly, how well you maintain the battery matters too. Regular maintenance, such as keeping it clean and properly charging it, can extend its life. Generally, you can expect an inverter battery to last a few years, usually around 3 to 5 years. But remember, just like toys, batteries eventually lose their juice and need to be replaced.

How long will my TV run off a 100Ah inverter battery?

In simple terms, the duration your TV will run off a 100Ah inverter battery depends on the power consumption of the TV and the efficiency of the inverter. TVs usually have a power rating indicated in watts (W). To estimate the runtime, divide the battery capacity (100Ah) by the power consumption of your TV in amps (A). For example, if your TV consumes 50W of power and operates at 240V, it would draw approximately 0.21A (50W ÷ 240V). With a 100Ah battery, the TV could potentially run for around 476 hours (100Ah ÷ 0.21A). However, please note that this is a rough estimate, and other factors such as inverter efficiency and battery condition can affect the actual runtime. Therefore, it’s important to consider these variables to get a general idea of how long your TV can run on a 100Ah inverter battery.

How long does it take to charge an inverter battery?

The time it takes to charge an inverter battery depends on the capacity of the battery, how many batteries you have, the charging speed of the charger and its efficiency. Typically, a standard charging process can take several hours. For example, if you have a 100 amp hour battery and use a charger that can deliver a charging current of 10 amps, it may take around 10 hours to fully charge the battery. 

Keep in mind that batteries should never be discharged fully as it can damage them. Some batteries can be discharged lower than others before needing to be charged. A lead acid battery should never discharge lower than 50% of its capacity. Because of this, lead acid batteries take a shorter time to fully charge. For lithium-ion batteries the depth of discharge is much higher than lead acid batteries. We recommend using on average around 80% of the battery capacity before it needs recharging. This means that your lithium-ion battery will take longer to charge then your lead acid battery. 

It’s important to consider the battery capacity and the charging specifications of your charger to get an approximate idea of how long it will take to charge your inverter battery. If loadshedding is too regular, your battery will not be able to fully charge off the main power supply. This is where getting solar panels installed is recommended.
