Load shedding turns a normal evening into a scramble for candles and lost Wi-Fi. The good news is that the right system keeps your lights, internet and essentials running through every stage. Here is a simple guide to backup power in Gauteng, from inverters and batteries to full solar, and how to pick what fits your home. For a full installation, see our energy services.
1. Start with what you actually need to run
Before buying anything, list what must stay on during an outage. Lights, Wi-Fi, a TV and phone chargers need very little. Fridges, microwaves and geysers need a lot more. That list decides the size of everything else.
2. Inverters and batteries: the quick win
An inverter and battery system charges from the grid when the power is on, then runs your essentials when it goes off. It is the fastest, most affordable way to ride out load shedding without a generator.
3. Solar panels: the long-term saver
Solar panels add free daytime power and cut your monthly bill. On their own they only work while the sun is up, so most homes pair them with a battery to carry that power into the evening.
4. Solar plus battery: the best of both
A solar and battery system gives you lower bills and reliable backup in one setup. The panels charge the battery by day, and the battery keeps you running at night and through outages.
5. What size system do you need?
Size comes down to two numbers: how much power your appliances draw at once, and how long you need to run them. A small home backup is very different from one that must keep a whole house going for hours.
6. Safety, wiring and lightning protection
Backup power must be wired in safely and certified. Good installs also include surge and lightning protection, which matters in Gauteng summers where storms can damage unprotected electronics.
7. Maintenance keeps it reliable
Batteries, panels and connections need the occasional check to stay at full capacity. A little maintenance now is far cheaper than a dead system on the night you need it most.
Choosing backup power in Gauteng
The right answer depends on your budget and what you cannot do without. Start with a load audit, decide between a battery backup or a full solar system, and have it installed and certified by a qualified team.
Key takeaways
- List your essentials first, then size the system around them.
- Inverter and battery is the quick win, solar and battery is the long-term saver.
- Always have it installed, certified and surge protected by professionals.
