With South Africa’s current energy supply situation, wealthier households may be planning a switch to entirely off-grid power solutions to escape load-shedding, but a majority of South Africans cannot afford such products.
There are more cost-effective solutions available that can keep essential equipment running during a load-shedding session.
Eskom has announced stage 4 load-shedding until 05h00 on Saturday, and expects to reduce to stage 2 load-shedding for the remainder of the weekend until 05:00 on Monday.
Currently, load-shedding is scheduled in sessions of two hours with an additional 30 minutes to switch networks, and the frequency of sessions varies depending on the current stage.
One of the most cost-effective ways to weather a two-hour rotational blackout is a battery backup system that can charge when power is available and supply energy during an outage.
If your only aim is to keep your Internet online during load-shedding, a small UPS or power bank with a DC port will best fit your needs.
Larger UPSs can be used to power your Internet connection, as well as a PC or TV through a load-shedding session.
Power solutions for your entire house can be pricey — you can expect to pay more than R20,000 for a small load-shedding kit.
However, if you need to power a few essential appliances through a session of load-shedding, there are several small petrol generators available to fulfil your requirements.
There are several online tools available to estimate the power usage of your appliances and electrical equipment.

Petrol generators are available in a range of sizes with varying power outputs. Even the larger generators listed below will not be able to power multiple power-hungry appliances with elements.
However, if your aim is to power some lights, your refrigerator, TV, and computers in addition to your Internet equipment, then a petrol generator can help you meet these needs.
