Backup power for every outage
PowerCut
PowerCut supplies practical backup power for homes and businesses in Randburg, Johannesburg and across Gauteng. We help size, supply and support inverter and lithium battery systems for load-shedding, power cuts and day-to-day reliability.
Right-Sized Backup
PowerCut helps clients choose inverter and lithium battery combinations that match essential loads, expected outage duration and room for future expansion.
Reliable Equipment
The focus is on dependable backup components selected for daily practicality, steady performance and compatibility with South African load-shedding conditions.
Safe Compliance
Installations must be completed by a registered electrician and issued with a certificate of compliance, while grid-tied systems also require municipal registration.
Local Support
Based in Randburg and serving Gauteng, PowerCut supports residential and commercial clients with product guidance, installation planning and after-sales assistance.

We supply inverter and lithium battery backup solutions sized for the way South African homes and businesses actually use power. That can mean keeping the lights on, running Wi-Fi and security, keeping a fridge going, or supporting a small office with computers, routers and point of sale equipment during load-shedding. The right setup depends on what must stay on, how long you need backup and what sort of loads you are carrying.
Our focus is on essential backup, not wasteful oversizing. We work with practical system parts that are commonly used in residential and commercial settings, including inverter units, lithium batteries, changeover equipment, protection devices and the wiring needed for selected circuits. In coastal or humid areas, good installation practice matters even more, because moisture and heat can shorten the life of poor quality work.

- Changeover solutions for safer switching between supply and backup

Sizing starts with what you need to keep running
A proper site assessment is where backup sizing should begin. We look at what needs to stay powered, the total load in watts or kilowatts, the starting surge of appliances and the number of hours you want to cover during an outage. A small home with lights, a fibre router and a TV needs a very different setup from a family home with a fridge, kettle and work-from-home equipment, and a business setup is different again.
We also consider future growth. If you plan to add more batteries later, or you want to start with essential loads and expand step by step, the system should be selected with that in mind. Battery chemistry, inverter capacity, cable size and protection all need to match. A battery that looks strong on paper can still underperform if the rest of the system is not matched correctly. That is why proper sizing matters, not guess work.

Fitted by registered electricians, signed off properly
All installations must be done by a registered electrician, and the finished work must include a Certificate of Compliance where required. If the system is grid-tied, it also needs to be registered with the local municipality. That applies to many households and businesses in Gauteng, and it is important to get the paperwork right from the start. Safe wiring, proper protection and correct changeover arrangements are not optional.
We support the process from site visit to final commissioning. That includes checking the site, planning the circuit layout, setting up the inverter and batteries, confirming protection devices, testing the changeover and helping with the information needed for compliance. In some properties, especially older homes or mixed-use premises, the existing wiring needs attention before backup can be connected properly. Sorting that out early saves time later and avoids nuisance faults.

We work with homeowners, landlords, small offices, shops, home businesses and other commercial clients who need dependable backup during outages. In Randburg and Sandton, many clients want compact systems for apartments, cluster homes or offices with limited space. In Pretoria and Centurion, we often see larger homes and business premises that need more battery capacity. In Midrand, Fourways and Roodepoort, clients commonly ask for setups that can support both comfort and work during repeated load-shedding.
Different properties need different answers. A household may want to keep the internet, lights and a few plugs on. A retail space may need till equipment and communication systems running. A professional office may need server room support or a controlled shutdown plan. We focus on the practical side of backup power so the system fits the property, the usage pattern and the available budget without overcomplicating things.

Do you help with sizing a backup system for my home?
Yes. We assess what you want to keep running, how long you need backup and whether you want room for future battery expansion.
Who is allowed to install the system?
A registered electrician must do the installation, and the completed work must include a Certificate of Compliance where required. Grid-tied systems must also be registered with the local municipality.
Which suburbs do your installers reach?
We work from Randburg and support clients across Johannesburg, Pretoria, Centurion, Midrand, Roodepoort, Sandton and Fourways, with broader Gauteng coverage by arrangement.
Where our installers travel
From our Randburg base, we supply and support clients across Johannesburg and surrounding Gauteng areas. That includes Randburg, Sandton, Fourways, Roodepoort, Midrand, Centurion and Pretoria. We also assist homes and businesses in nearby suburbs where reliable backup has become part of everyday planning, especially during long outages or repeated municipal interruptions.
If you are comparing options, it helps to start with a site assessment and a proper backup plan. We can then look at what must stay on, how the system will be wired and whether you may want to add more battery capacity later. Write to PowerCut through the contact page form and we use that to gather the basics before moving to the next step. That keeps the process orderly and makes it easier to plan correctly from the start.

What happens after the system is switched on
Once a system is running, most calls are about growing it: a second battery when the family grows, a solar input added later, or a changeover switch moved when the DB board is upgraded. We keep the original sizing sheet and wiring notes for every Randburg and Gauteng install, so an upgrade starts from what is already on the wall.
Sifiso Ngobeni plans each system and signs off the sizing. Ayesha Ntuli books site checks, Marnus Rabie leads the electricians on site, Nompumelelo Sigcau orders and tracks equipment, Sibusiso Govender handles after-install visits and Rentia Fouche answers the phone and the contact form.
