Load shedding turns a quiet evening in Hillcrest into a scramble for candles and cold coffee. The good news: backup power has never been more affordable or reliable. The catch: there's a lot of marketing noise, and the wrong system (or a bad install) is money down the drain. Here's how to choose well.
First, work out what you actually want to run
Backup power isn't one-size-fits-all. Before looking at products, list what must stay on during an outage:
- The essentials — Wi-Fi router, a few lights, phone chargers, the TV. Small and cheap to back up.
- Comfort — fridge/freezer, a fan, maybe a small microwave. Mid-range.
- Everything — including the geyser, stove, kettle and pool pump. This is a different league entirely.
High-demand heating appliances — geysers, kettles, stoves, heaters — are the budget killers. Most home backup systems deliberately leave these off the backup circuit.
Your three main options
1. Plug-in inverter trolley / power station
The simplest option: a portable unit you plug appliances into directly. No installation, no certificate, fully portable. Great for keeping the router, a light and a laptop alive. The downside is limited capacity and the hassle of running extension leads.
2. Inverter + battery (hard-wired)
A fixed inverter wired into your DB board powers selected circuits automatically the instant the power drops — no plugging in, no noise, no fumes. This is the sweet spot for most Upper Highway homes: lights, plugs, fridge and entertainment stay on seamlessly. Add more batteries later as budget allows.
3. Solar + inverter + battery
Add solar panels and you're not just surviving load shedding — you're cutting your monthly bill and charging your batteries for free during the day. The upfront cost is higher, but in sunny KZN the payback can be very attractive, especially as tariffs climb.
Why correct installation matters more than the brand
This is where people get burned. A backup system isn't a plug-and-play gadget — it ties into your home's wiring, and a poor install is genuinely dangerous. Key things a certified electrician gets right:
- Proper changeover so your inverter can never feed power back into the grid — a deadly hazard for municipal workers, and illegal.
- Correct circuit selection so heavy loads don't overwhelm the inverter and trip it constantly.
- Safe battery placement and ventilation, with the right cabling and fusing.
- A Certificate of Compliance for the new installation — needed for insurance and peace of mind.
Common mistakes we see
"I bought a big inverter online but it keeps tripping when the kettle goes on." — Almost always an oversized load on an undersized or badly configured system.
Other classics: batteries stuffed into a hot, sealed cupboard; DIY wiring with no changeover protection; and systems sized for a brochure rather than the actual house.
