Battery Backup Systems for Homes & Businesses
Keep the lights on, the fridge running, and your business operating — whatever Eskom is doing.
Load shedding is not going away. The question is how you deal with it.
South Africans have lost thousands of hours to load shedding over the past decade, and the grid remains under pressure. A battery backup system gives your home or business a reliable power reserve that kicks in automatically the moment the grid goes down — no generators, no noise, no fuel, no manual switching.
Whether you want to protect essential loads or keep your entire property running through any stage of load shedding, we design and install battery backup systems sized to your actual needs.
What is a Battery Backup System?
A battery backup system stores electricity — either from the grid, from solar panels, or both — and supplies it automatically when the grid fails. A battery inverter monitors your supply continuously and switches to stored power within milliseconds of an outage, before most appliances even register the interruption.
Used standalone, a battery backup system charges from the grid during normal supply and discharges during load shedding. Paired with solar panels, it charges from the sun first — reducing your electricity bill and extending your backup capacity at the same time.
The result:
- Seamless, automatic backup during load shedding
- No noise, no fumes, no fuel costs
- Protection for sensitive electronics and appliances
- The foundation for a solar upgrade when you are ready
Is a Battery Backup System Right for You?
Battery backup systems are ideal for:
Homeowners
Families wanting reliable protection from load shedding without the full commitment of a solar installation. Lights, Wi-Fi, a fridge, a TV, and phone charging — the essentials covered, automatically.
Home Offices & Remote Workers
Load shedding during working hours is a productivity and income problem. A battery backup system keeps your router, screens, and devices running through any scheduled outage without interruption.
Guesthouses & Short-Term Rentals
Guests do not want to sit in the dark. A battery backup system ensures uninterrupted power through load shedding, protects your reviews, and removes a variable entirely outside your control.
Retail & Small Businesses
Point-of-sale systems, refrigeration, lighting, and security — a battery backup system keeps your business trading and your stock protected through every stage of load shedding.
Medical & Sensitive Equipment
CPAP machines, home medical equipment, and sensitive electronics need uninterrupted, clean power. A battery backup system provides exactly that, automatically and silently.
How it works
1
Load Assessment
We establish which appliances and circuits you need backed up, how long you need them to run during an outage, and whether you want to add solar now or leave that option open for later. This determines the right battery capacity and inverter size.
2
System Design
We design a battery backup system matched to your backup requirements and budget — selecting the right inverter, battery technology, and capacity to cover your critical loads through a realistic load shedding schedule.
3
Installation
Professional installation by certified installers. Inverter, battery bank, wiring, and a dedicated backup distribution board — all installed neatly and safely to SANS standards, with minimal disruption to your property.
4
Support & Maintenance
Battery health checks, inverter servicing, and ongoing support keep your system ready when you need it. We are your long-term energy partner — not just a once-off installer.

“
For more than 8 years, my family and I have lived completely off-grid on our farm in Keurbooms, Plettenberg Bay, powered entirely by solar energy and harvested rainwater — with no Eskom and no municipal water.
During that time, we have built and connected four homes to a single off-grid system. Three of these homes are very busy Airbnb rentals, providing ongoing real-world testing of the system under varying occupancy and demand.
Living this way every day has given me firsthand insight into what truly works. The solar and water solutions I recommend are based on years of practical experience and a deep understanding of what it takes to achieve reliable, long-term independence.

We design and install battery backup systems for homes and businesses across the Garden Route, from George to Plettenberg Bay. Automatic, reliable protection from the moment it is installed.
Frequently Asked Questions
A residential battery backup system typically ranges from R35,000–R100,000 depending on the inverter size, battery capacity, and the loads you want covered. We provide a detailed quote after assessing your requirements.
Runtime depends on battery capacity and the loads drawing from it. We size your system during the design phase to comfortably cover your critical loads through a realistic Stage 4–6 load shedding schedule. Larger batteries or fewer loads extend the runtime accordingly.
A battery backup system switches automatically in milliseconds, produces no noise or fumes, requires no fuel, and needs minimal maintenance. A generator requires manual starting, fuel management, and produces noise and exhaust. For most residential and light commercial applications, a battery backup system is a cleaner and more convenient solution.
Yes. We design every battery backup installation to be solar-ready. Adding solar panels at a later stage upgrades your system to a full hybrid — charging your batteries from the sun and reducing your electricity bill alongside your load shedding exposure.
Lights, Wi-Fi router, television, refrigerator, computers, phone charging, and other essential appliances — a standard residential system handles these comfortably. High-draw appliances like geysers, electric stoves, and air conditioners require larger capacity, which we factor in during the design phase if needed.
Quality lithium battery banks typically last 8–15 years depending on usage cycles and system management. We specify batteries appropriate to your usage profile and advise on best practices to maximise their lifespan.
Yes. We install battery backup systems in Plettenberg Bay, Knysna, George, Wilderness, Sedgefield, and surrounding farms and estates throughout the Garden Route.
