Understanding Load Shedding in South Africa
Eskom has been cutting power to South African homes since 2007. For residents in Pretoria, Centurion, and Gauteng, it is not just an inconvenience, your alarm goes offline, the fridge defrosts, the internet drops, the gate motor stops working, and you cannot cook dinner.
South Africa's power grid is not getting fixed anytime soon. Backup power is no longer a luxury, it is a necessity. The upside is there are more options now than ever before, from a R3,000 UPS that keeps your Wi-Fi alive to a full solar and battery setup that takes you off the grid entirely.
Below is every major load shedding solution available to Pretoria homeowners in 2026, with realistic costs and honest pros and cons.
Current Load Shedding Reality
- Eskom manages load shedding in stages from Stage 1 (1,000 MW shed) to Stage 8 (8,000 MW shed)
- The City of Tshwane publishes separate load shedding schedules for Pretoria residents
- Stage 2 load shedding can mean 4+ hours without power per day
- Higher stages can leave homes without power for 8–12 hours daily
- Even during periods of reduced load shedding, the grid remains vulnerable to sudden outages
Generator Solutions for Your Pretoria Home
A generator installation in Pretoria remains one of the most popular and reliable backup power solutions. Generators can power your entire home or selected circuits, depending on the size and type you choose. They offer immediate, high-capacity power that other solutions may struggle to match.
There are three main types of generators suitable for residential use:
Petrol Generators (Portable)
Affordable and widely available. Ideal for powering essentials like lights, a fridge, and charging devices. Typically range from 2 kVA to 8 kVA. Running costs are moderate, but they require manual start-up and can be noisy. Prices start from around R5 000 to R25 000 depending on output.
Diesel Generators (Standby)
More fuel-efficient than petrol generators and better suited for longer outages. Available in larger capacities (5 kVA to 20+ kVA) for whole-home backup. Diesel generators are more durable and have lower running costs per hour, but they have a higher upfront price, typically R15 000 to R80 000 or more for residential units.
Automatic Transfer Switch (ATS) Generators
The gold standard for convenience. These generators detect a power outage and start automatically within seconds, then switch back once grid power returns. Paired with a diesel or LPG generator, an ATS system ensures seamless power continuity. Installation with a changeover switch typically costs R8 000 to R20 000 on top of the generator price.
Important: Generator Changeover Switch
By law in South Africa, all generator installations must include a properly installed changeover switch to prevent back-feeding into the municipal grid, which is extremely dangerous. INC Unlimited installs all generator changeover switches in full compliance with SANS 10142 regulations. View our electrical services for more details.
Inverter and Battery Backup Systems
An inverter battery backup in Pretoria is arguably the most popular modern solution for load shedding. These systems store energy in lithium-ion or lead-acid batteries and automatically supply power to your home the moment the grid goes down, silently, instantly, and with zero intervention required.
Unlike generators, inverter systems produce no noise, no fumes, and require minimal maintenance. They can also be paired with solar panels for a hybrid system that reduces your reliance on Eskom even when load shedding is not active.
Lithium-Ion (LiFePO4)
The premium choice. Lithium batteries offer 5,000+ charge cycles, are lighter, charge faster, and have a 10-year lifespan. Popular brands include Hubble, Pylontech, and Freedom Won. A 5 kWh lithium battery costs R15 000 to R25 000.
Lead-Acid / AGM Batteries
A more affordable entry point at roughly R3 000 to R8 000 per battery. However, they are heavier, have fewer charge cycles (500–1,000), and a shorter lifespan of 2–4 years. Best suited for budget-conscious setups.
Inverter/Charger Unit
The brain of the system. Converts stored DC battery power to AC power for your home. Quality inverters from brands like Victron, Sunsynk, and Deye range from R8 000 to R30 000 depending on capacity (3 kW to 8 kW).
Typical System Cost
A complete 5 kW inverter with 5 kWh lithium battery setup for essential circuits (lights, plugs, Wi-Fi, alarm, gate motor) typically costs R30 000 to R55 000 fully installed in Pretoria.
Solar Panel Installation in Gauteng
Solar installation in Gauteng has taken off. Pretoria gets 8 to 10 hours of direct sunshine per day in summer, some of the best solar conditions in the country. A properly sized system does not just keep the lights on during load shedding. It slashes your monthly electricity bill year-round.
There are three main types of solar installations for residential properties:
Grid-Tied Solar (No Battery)
Solar panels feed electricity directly into your home during the day, reducing your Eskom consumption. Excess power may be fed back to the grid if your municipality allows it. This is the most affordable solar option (R40 000 to R80 000 for a 3–5 kW system) but provides no backup during load shedding since it shuts down when the grid is off.
Hybrid Solar (With Battery)
Combines solar panels with a battery bank and hybrid inverter. During the day, solar charges the batteries and powers the home. During load shedding or at night, the batteries take over. This is the most popular option for Pretoria homeowners seeking both savings and backup. A 5 kW hybrid system with 10 kWh storage typically costs R80 000 to R150 000 installed.
Off-Grid Solar
Complete independence from Eskom. Requires a large solar array, substantial battery storage, and careful energy management. While achievable, this is the most expensive option (R150 000 to R350 000+) and is generally only practical for homes with moderate energy consumption or those in areas with very unreliable grid supply.
The South African government currently offers a 25% solar panel tax incentive for individuals, allowing you to claim up to R15 000 per person on your tax return for qualifying solar PV panels installed at your residence. This can significantly reduce the effective cost of a solar installation.
UPS Systems for Essential Equipment
An Uninterruptible Power Supply (UPS) is the simplest and most affordable entry point for load shedding protection. UPS units are designed to provide short-duration backup power, typically 30 minutes to 4 hours, for specific devices like computers, Wi-Fi routers, security cameras, and alarm systems.
While a UPS will not power your entire home, it is an excellent solution for keeping critical electronics running during shorter outages or as a bridge until a generator starts up.
Pro Tip: Layered Approach
Many Pretoria homeowners combine a UPS for instant protection of sensitive equipment with a larger inverter or generator system for extended outages. This layered approach ensures your alarm, cameras, and internet stay online during the few seconds it takes for the main backup system to kick in.
Gas Solutions: Stoves, Geysers & Heating
Not every load shedding solution needs to involve electricity. Switching key appliances to gas is a practical and cost-effective way to reduce your dependence on the grid. Gas stoves, gas geysers, and gas heaters operate completely independently of Eskom, meaning they work perfectly during any stage of load shedding.
Here are the most popular gas alternatives for Pretoria homes:
Gas Stoves & Hobs
Freestanding or built-in gas hobs start from around R3 000 to R12 000. They provide instant heat, precise temperature control, and zero electricity usage. Installation requires a certified gas installer and a valid Certificate of Conformity.
Gas Geysers (Instant)
An instant gas geyser heats water on demand without a storage tank. Prices range from R4 000 to R12 000, with installation costing an additional R3 000 to R6 000. They use LPG gas and are ideal for households wanting hot water regardless of power status.
Gas Heaters
Portable and fixed gas heaters are an effective way to keep warm during winter load shedding. Prices range from R800 to R5 000. Always ensure adequate ventilation when using indoor gas heaters.
LPG Supply
LPG (liquefied petroleum gas) is readily available throughout Pretoria and Centurion from suppliers and retail outlets. A standard 9 kg gas cylinder costs R250 to R400 and lasts 2–4 weeks depending on usage.
Comparing Load Shedding Solutions: Cost vs Benefit
Choosing the right backup power solution in Centurion or Pretoria depends on your budget, energy needs, and how much of your home you want to keep running during outages. Here is a side-by-side comparison of the main options:
| Solution | Typical Cost | Runtime | Best For |

Choosing the Right Load Shedding Solution for Your Home
There is no single best solution, the right choice depends on your specific circumstances. Here are the key factors every Pretoria homeowner should consider before investing in a load shedding solution:
Assess Your Power Needs
Start by listing what you absolutely need to keep running during load shedding. For most homes, this includes lights, the fridge, Wi-Fi router, alarm system, gate motor, and a few plug points. A 5 kW inverter with a 5 kWh battery can typically handle these essentials for 4–6 hours.
Consider Your Budget
Be realistic about what you can afford. A UPS at R2 000 or a gas stove at R5 000 is far better than no backup at all. You can always start small and expand your system later, many inverter setups are modular and allow you to add more batteries over time.
Think Long-Term
While a generator has a lower upfront cost, ongoing fuel expenses add up. A solar hybrid system costs more initially but can pay for itself within 5–7 years through electricity savings, even outside of load shedding periods.
Property and Lifestyle Factors
Consider your roof orientation (north-facing is ideal for solar in South Africa), available space for batteries or a generator, noise sensitivity (generators vs silent inverters), and whether you work from home and need uninterrupted power.
Resale Value
A professionally installed solar or inverter system can increase your property value in Pretoria. Buyers increasingly look for homes with existing backup power solutions, making it both a practical and financial investment.
Why Professional Installation Matters
Regardless of which load shedding solution you choose, professional installation is not optional, it is essential.
