When planning residential solar power systems, there are several decisions to make, including what size inverter you need, how many solar panels it will take to power your appliances and which type of solar system suits your home. In this guide, we explain how each system works, the equipment involved and the pros and cons of each option, so you can choose with confidence.
What Is an Inverter and Why Do You Need One?
As load shedding continues to disrupt everyday life across South Africa, more and more homeowners are turning to backup power solutions. At the heart of every reliable solar or battery system is a key component, the inverter. But what exactly does it do, and why is it essential for your home energy? An inverter is a smart solar energy device that converts direct current (DC) which is the type of current that is stored in batteries or rather produced by solar panels into alternating current power (AC) which is used to power appliances around your home. Without an inverter, your solar panels won’t be able to power your fridge, lights, or even your WIFI during loadshedding. In more basic terms – the inverter acts as the translator between your backup power source and your home’s electricity needs.
Types of Inverters for Home Use
1. Hybrid Inverters
Hybrid inverters are becoming increasingly popular in South Africa because they offer the best of all worlds. A hybrid solar inverter can utilise power generated from your solar panels, allow you to store excess power in the form of battery storage and use grid electricity when required. A hybrid system allows you to prioritise solar and battery usage to reduce your electricity bill while still having the safety net of the grid when solar generation is low. Many hybrid inverters also come with smart load management features and mobile apps that let you monitor your usage and system performance.
2. Off-Grid Inverters
Off-grid inverters are designed for homes that operate completely independent from the Eskom grid – either because they looking to generate their own solar power or often for remote properties or farms who may not have access to a reliable energy supply. This means that these systems rely solely on the solar panels and batteries to provide electricity during the day and night – this often means that you need to have more battery backup capacity installed to ensure you storing all excess energy required. These systems are therefore often more expensive and rather more planning to ensure that you have enough power to meet your households needs all your round.
3. Grid-Tied Inverters
Grid-tied inverters are then connected directly to the municipal power grid and don’t use any form of battery storage. These types of systems work by converting solar energy generated by your solar panels into usable electricity during the day. However, they do not include any form of battery backup power system so during loadshedding or power outages, they are dependent on the Eskom grid. This effectively means that grid-tied systems are for homeowners looking to save electricity costs by using solar energy during the day and are less concerned about battery backup power.
Pure Sine vs Modified Sine Wave Inverters
A pure sine wave inverter produces electricity that closely mimics the smooth, stable power you receive from the grid. This clean waveform ensures that sensitive devices such as laptops, TVs, refrigerators, and medical equipment operate efficiently, quietly, and without overheating or electrical noise. Because they use higher-quality components and offer more stable output, pure sine wave inverters are generally more expensive but they’re also more reliable and suitable for almost all home and business applications.
By contrast, a modified sine wave inverter generates a stepped or box-shaped current that isn’t as smooth. While it can power basic devices like lights, fans, and phone chargers, it can cause problems with equipment that includes motors or compressors. Appliances powered by modified sine wave inverters may run hotter, less efficiently, or even make audible humming or buzzing sounds. These inverters are more affordable, making them a budget-friendly option for simple backup systems, but they’re not ideal for powering sensitive electronics long-term.
Do I Need a Battery for My Inverter?
Whether or not you need a battery for your inverter depends on the type of system you choose and what you want to achieve. If your main goal is to stay powered during load shedding or outages, then yes — a battery is essential. The battery stores energy (either from solar panels or the grid) so that when the power goes out, your inverter can draw from that reserve to keep your lights, Wi-Fi, and appliances running. Without a battery, a typical inverter won’t have any energy to supply during a blackout. However, if you're using a grid-tied inverter purely to reduce your electricity bill during the day, a battery isn’t required — but you also won’t have backup power when the grid fails. On the other hand, hybrid inverters are designed to work with or without batteries, allowing you to start small and add storage later as your budget allows. That said, most South African homeowners choose to pair their inverters with lithium batteries for a reliable and uninterrupted power supply, especially with the unpredictability of load shedding in 2026.
Best Inverter Setup for Load Shedding?
Having a reliable solar powered solution can make a huge difference and give you that added peace of mind that you can carry on with your normal day to day life. One of the most practical and cost-effective options to deal with loadshedding is having a hybrid inverter paired with a lithium battery. Depending on the size of your property and what you looking to power – the inverter needed may vary but as a general rule of thumb a 5Kva hybrid inverter is perfect for powering essential household appliance such as lights, TVs or laptops during loadshedding. When combined with a 5kWh to 10kWh lithium battery and a small array of solar panels (around 3kW to 5kW), this setup allows you to charge your batteries from the sun during the day and run your home during loadshedding all without touching Eskom’s power.
Installation, Safety and Compliance
An inverter is only as reliable as its installation. Your system should be installed by a registered electrical contractor and issued with a Certificate of Compliance, which insurers often ask for when you make a claim. If your hybrid system is connected to the grid, it will also normally need to be registered with your municipality or Eskom. Our guide to solar registration in Durban explains the process.
Placement matters too. Inverters and lithium batteries need good ventilation, protection from sun and rain, and a safe location away from flammable materials. Our guides on fire protection for homes and protecting your solar system from theft cover how to keep your equipment safe.
What Size Inverter Do I Need?
| Inverter size | Typically suits | What it can usually run |
|---|---|---|
| 3kVA | Small homes, flats and townhouses | Lights, Wi-Fi, TV, laptops and chargers |
| 5kVA | Most family homes | Essentials plus a fridge, microwave and home office |
| 8kVA | Larger homes | Most of the house, including some heavier appliances |
| 10kVA and above | Large homes and small businesses | Whole-home backup and higher loads, often on three-phase supply |
What to Look for When Choosing an Inverter?
1. Understand Your Power Needs
Before making the decision on the size of the inverter you require – it’s important to have a clear picture of your household’s current energy consumption. This is important to ensure that you can keep all your core appliances running during loadshedding as the total wattage they require may influence what type of inverter you need to choose. If you’re unsure where to start, a quick consultation with a solar energy expert at EagleEyeSolutions or alternatively try using an online calculator.
2. Features That Add Value
Many of the modern inverters that you can purchase today come with a variety of cool and up-to-date features that can help make your life easier. Real time system monitoring via a smartphone app, load prioritisation settings and automated switching between solar, battery usage and grid supplied power are just some of the smart tools you may find that can help improve the convenience of your setup.
3. Support, Warranty, and Service
Solar energy systems, specifically solar inverters are a long-term investment, so it’s worth choosing a brand that offers quality after sales support and a solid warranty plan to ensure you are covered. This is not specific to the solar industry but rather if anything goes wrong, you’ll want to deal with a company with good communication structures in place and has trained employees available in your area. A reliable support structure can make all the difference when it comes to keeping your power system running smoothly.
