How Loadshedding Affects Businesses In SA

In recent years, loadshedding has become a pervasive issue in many regions, significantly impacting businesses across various industries. Loadshedding, a controlled shutdown of electricity supply implemented by utility companies (or Eskom in South Africa), can have severe consequences for businesses, ranging from financial losses to operational disruptions. Understanding the negative impacts of loadshedding is crucial for businesses to develop strategies to mitigate its effects and ensure continuity.

Top Solar Inverters To Choose From In South Africa

As South Africa faces frequent power outages and rising electricity costs, more and more people are turning to alternative energy sources such as solar power. A solar energy system with a backup battery and a solar inverter can provide uninterrupted power during load shedding, which is why installing one is now at the front of many home and business owners’ minds.

One of the most important components of a solar energy system is the solar inverter. Understanding the different types of solar inverters available in South Africa is crucial in deciding which of the top brands to choose from, and how to select the right solar inverter for your application needs. 

What is a Solar Inverter?

A solar inverter is a device that converts the DC (direct current) generated by solar panels into AC (alternating current) that can be used to power household appliances and other electrical devices or fed back into the grid. 

AC is the type of electrical current that is supplied by power plants and is used in most homes and businesses to power appliances, electronics, and lighting. AC voltage and current periodically change direction, meaning the flow of electricity switches back and forth in a regular pattern. 

DC, on the other hand, is a type of electrical current that flows in a single direction. It is commonly used in batteries and electronic devices, such as smartphones, laptops, and TVs.
We can therefore see why the inverter is such a critical component of a solar energy system, as it ensures that the energy generated by the solar panels is usable. 

Types of Solar Inverters:

There are several types of solar inverters available in South Africa, each with their own pros and cons. Here are the most common types of solar inverters available in the market:

Hybrid Inverter

Hybrid inverters, which are the most common type of inverter used in South Africa, are a combination of a grid-tied and an off-grid inverter, and so they can be used for both applications. This technology also allows you to store excess solar energy in batteries, which then can be used during power outages or at night when there is no sun.

They can operate in both grid-tied and off-grid modes, making it ideal for areas with unreliable electricity supply. Hybrid inverters can also be programmed to prioritise solar power over grid power, reducing electricity bills and minimising reliance on the grid.

Off-grid Inverter

This type of inverter is used in off-grid solar energy systems. It is designed to handle a range of loads and can be used with battery backup systems.

An off-grid inverter is designed to work with a battery bank and is used in standalone solar power systems that are not connected to the grid. Off-grid inverters are more expensive than grid-tied inverters but allow for complete energy independence, and they can be used in remote locations where grid power is unavailable.

Grid-Tied Inverter

Designed for use in on-grid solar energy systems, this type of inverter is only usable when mains power is available, as it is connected to the grid. It allows you to feed excess energy back into the grid to reduce your electricity bill. While this type of inverter is a great way to save money, it is not as useful in a context of frequent power outages. 

3-Phase Inverter

This type of inverter is used in commercial and industrial solar energy systems. It is designed to handle high loads and is more efficient than other types of inverters.

A 3-phase inverter is designed for use in commercial and industrial applications that require three-phase power. These inverters are capable of handling large loads and can be used in conjunction with battery backup systems.

Top Solar Inverter brands to choose from:

When it comes to choosing the right solar inverter for your solar energy system, selecting a reputable brand is crucial to ensure the highest quality and efficiency. Enertec Batteries offers a range of solar inverters from top brands in the industry. 

Here are some of the top solar inverter brands to choose from:

How to choose the right Solar Inverter for your application needs?

Choosing the right solar inverter for your needs can be a daunting task, especially if you are new to solar energy. 

Here are some factors to consider when choosing a solar inverter:

System Size: 

The size of your solar energy system will determine the size of the inverter you need. A small solar energy system will require a small inverter, while a larger system will require a larger inverter.

The size of the solar inverter should be compatible with the size of the solar panels in your system. A larger inverter may be necessary if you plan to expand your solar power system in the future.


Type of System: 

The type of solar energy system you have will also determine the type of inverter you need. If you have an off-grid system, you will need an off-grid inverter, while an on-grid system will require a grid-tied or hybrid inverter.


Inverters have an efficiency rating, which is the percentage of DC electricity that is converted into usable AC electricity. So, a more efficient inverter will convert more of the energy generated by the solar panels into usable electricity. Higher efficiency inverters can help increase your energy savings. 

The efficiency of the solar inverter is important as it affects the overall efficiency of the solar power system. 

Brand reputation: 

The reputation of the brand and the quality of the solar inverter should be considered when making a decision. It is important to choose a reliable and reputable brand that produces high-quality solar inverters.


The warranty offered by the manufacturer is another important factor to consider. A longer warranty period will give you peace of mind and protect your investment in the event of any defects or malfunctions.


Cost is another crucial factor to consider when choosing a solar inverter, but it should not be the only factor in the decision-making process. While it is important to stay within your budget, it is also essential to invest in a high-quality inverter that will last for years to come.


Some inverters have advanced features such as dual MPPT (maximum power point tracking), which can help optimise the output of your solar panels in different conditions, such as when they are partially shaded. Some solar inverters are also "smart" and can communicate with other devices in your solar system, such as batteries or energy monitors. This can help optimise your energy usage and maximise your savings.

There is no single "best" solar inverter, as it depends on various factors such as the application, system size, budget, and personal preferences. It is important to choose a solar inverter that is compatible with your solar panels and battery bank (if applicable), and that meets your power requirements. It is recommended to consult a professional solar installer or supplier to determine the best solar inverter for your specific needs and requirements.
