Do you really need that inverter - pro's and cons

PUBLISHED 12 OCT 2020   

One of the few upsides of the recent lockdown was a lack of load shedding - but with the economy back in gear the burden on the Eskom power grid has increased once again. 

For households across Cape Town, the inconvenient prospect of power cuts has returned. Many homeowners are considering investing in an inverter to keep the lights on - but is this the wisest choice for you? 

In this article we’ll take a look at some of the pros and cons of installing your own power supply. 

Inverter vs. generator - what’s the difference?

Before we get into specific recommendations, let’s start with the basics about inverters and how they differ from generators.  

  • generator is a piece of machinery that produces electricity using fuel - typically some form of combustible liquid like petrol. 
  • An inverter is more like a giant battery that charges itself using Eskom power when the lights are on, and supplies power to your home when they go off. It doesn’t use any type of liquid fuel - but it requires large batteries to store power. 

The Benefits of using an inverter 

The biggest advantage of using an inverter instead of a generator is that it’s clean, easy, and doesn’t require much maintenance. 

Since an inverter is set up to charge itself automatically and switch on as soon as the power goes down you won’t need to worry about your CCTV system or fridge switching off if you’re not at home during load shedding. 

How much does an inverter cost?

There are various types of inverters available - and the price you’ll pay all depends on how much power you require. 

  • A small inverter that could power a few electronic devices for a maximum of four hours is likely to cost you between R6 000 and R10 000
  • If you’d like to power most of your lights and a few appliances, you’ll need a larger inverter with at least two backup batteries. This will cost roughly R40 000
  • At the higher end of the spectrum would be a 48v, 10 000w model that could power most of your household and could cost up to R70 000. 
A key decision that could boost your home’s value 

While inverters may not be cheap, they serve an essential purpose that will be necessary as long as load shedding exists. Convenience aside, installing one of these devices could make your home more desirable in the eyes of potential buyers or renters. Alternatively, you have the option of relocating an inverter in your new home.
