Solar Inverters

Solar Inverters are the heart of any Solar Power or Load Shedding Kit.

The primary function of the Solar Inverter is to convert DC power into AC power which we use in our homes. Solar Batteries store DC power, so the inverter will also convert the energy coming from the battery into usable AC power.

Another task the inverter has is to manage the charge and discharge of your battery, ensuring the overall health of your Solar Power or Load Shedding system is in good nick.

Types of Inverters

You have four main types of solar inverters, Grid-Tied, Off-Grid, Hybrid and 3 Phase Inverters.

Each has its own specific needs, so it’s essential to understand which one will suit your needs.

To better understand the types of Inverters and you’d prefer to not read our guide, watch our short video guide.

Different Capabilities

You are presented with a different range of inverters because you have specific energy needs. This is why we encourage everyone to read our solar guide, which covers all the basics.


Hybrid

Your Hybrid Solar Inverter is the best option overall. It can be used as a Grid-Tied and Off-Grid solar solution.

Its main advantages are that it can blend energy sources (Solar, Battery & Grid) to make the most efficient system possible.

The blending capabilities of the Hybrid are a guarantee that you are not wasting any produced solar power. They are an excellent investment because of this feature and will see you saving thousands of rands on grid-supplied electricity in the long run.

Off-Grid

The classic Off-Grid inverter has been around for quite some time.

A major downfall of these types of inverters within Solar Power Kits is that if your usage exceeds the amount of solar power you are producing, the Off-grid inverter will switch over to the grid. Ultimately seeing you waste precious (and free) solar power.

However, they are more affordable than a Hybrid inverter and work perfectly in Load Shedding Kits. But, if you want to add solar later, we strongly suggest a Hybrid Inverter.

A Quick Guide on Off-Grid Inverters | Solar Advice


Grid-tied

A Grid-tied Inverter allows you to switch between solar and grid power. When solar power is available, it will be used as the primary energy source. But when solar energy is low, it switches to grid power.

Grid-tied systems are ideal for homes or businesses that use most of their power during the day and want to substitute their grid usage with solar power.

3 Phase

3 phase power supply requires a 3 phase inverter.

However, if you are looking for a 3 phase hybrid inverter but can’t find the size you need, you can also use one single-phase inverter on each of your phases, so you’ll need 3 single-phase inverters if you want all 3 phases covered.

Whatever the application, we have a solution.

Choosing the Right Inverter

Buying the right solar inverter in South Africa is very important, but you’ll need to have a goal in mind when choosing one.

Hybrid Inverters can be used in Off-Grid and Grid-Tied systems. They are versatile, making them the best choice.

If you’re planning on adding solar panels to your load shedding kit at a later stage, the Hybrid Inverter will be your best bet due to the blending capabilities of these inverters.

If you’d like to supplement your daily grid usage with solar power, a Hybrid is recommended again due to its blending capabilities.

Inverter Prices

As you can see from the listings above, the solar inverter prices differ. While the Hybrids cost more than Off-Grid inverters, the Hybrid offers more bang for your buck, and this is what you’re paying for. Prices also vary depending on the size of the inverter and the brand name.

A quick Google search for solar inverters for sale will give you many options but be careful of choosing the cheapest option available. Do your research and speak to a few solar professionals for advice.

Quality Inverter Brands

Brand names matter when you shop for solar equipment.

Reputable brands become firm favourites for a reason, and this is mainly due to the reliability of the product.

Most Lithium-ion brands are compatible with Deye inverters making them a top choice amongst installers.

Goodwe

Goodwe is a company that specialises in converting solar energy. And the models it has produced up to now paved the way for all its major projects. From Korea and Holland to India and Turkey, Goodwe is responsible for projects scaling 10MW and upwards.

Voltronic & Voltronic Types

For individuals on a budget looking to start their journey with solar power, Axpert is a familiar brand name in the solar market. Designed and developed by Voltronic Power (established in 2008 as UPS solution specialists), Axpert inverters have built a reputation for being incredibly stable and efficient.
Voltronic Type Inverters are essentially a copy of the Voltronic Inverters. Even Growatt Off-Grid Inverters’ design is based on the original Voltronic Inverters.
