Computer and IT equipment depends on a consistent power supply to stay on, but with the frequent load shedding can damage your computer and IT Equipment.

A sudden loss of power, as experienced during load shedding, can damage both your IT Infrastructure, data and your hardware. Powering down your system can, before load shedding , alleviate any damage to equipment and data:

If the operating system is busy passing important data while power is lost, the sudden cut will corrupt the files and even the operating system. 

In some cases, hard drive, head-and-write, which hovers over the spinning platters during operation, snaps back to PARK. If this happens frequently, the head arm will miss-align over time, causing it to touch and scrape the platter surface. This develops into a head disk crash where the hard drive is effectively damaged particularly if you have Solid State drives. It can also suffer catastrophic damage ranging anywhere from data corruption to total malfunction. 

Cloud storage is a good option to store your data as a backup, you still need to consider if you have an open file / folder it may corrupt at the time of load shedding. 

Considering the above, it’s a good idea to invest in some anti-load shedding precautions. It is recommended to install pure sine wave UPS or inverter with surge protection. 

Pick your UPS or inverter carefully 

  • Low watt inverter does not last very long
    • Consider how many batteries the unit has installed
    • How much equipment will you be running during load shedding?
    • How long will it take to charge the batteries between load shedding times
    • How long the load shedding is, the longer the batteries will take to charge
    • Solar is a great option
  • UPS is used to help 
    • Shutdown your systems
    • UPS will give the generator time to turn on
    • UPS is not going to last out a load shedding without a generator

DO NOT let your batteries go under 50% when you have load shedding, this will help keep the batteries healthy and last longer. 

Only run what you need and no extra equipment on your UPS or Inverter.


Running on a recommended small inverter 2Kw 24V 2x100A Batteries | includes 800W MPPT Solar Charge Controller optional | 220Vac Work on this scale of the load you use on above inverter at 50% battery loss Load 200w = 6hrs | 400w = 3Hrs

Not recommended 600w = 2Hrs | 800w = 1Hr 30mins | Max Load 1000w = 1Hr 10Mins
