Backup power in Tembisa is about choosing what stays on. Lights, Wi-Fi, gate motor, alarm and a fridge is an affordable system. Adding the geyser, the stove and the pool pump is a different conversation — and we will have that conversation honestly before you spend anything.
Tembisa is one of Gauteng’s largest townships — dense original housing, extensive backroom rental accommodation and a substantial informal and small-business economy. That mix is what makes the electrical work here so varied — and why we keep teams working this area rather than sending someone across Gauteng.
Because Tembisa falls under City of Ekurhuleni and is supplied by Eskom and Ekurhuleni Energy, anything that touches the connection itself follows their process and their timelines. We work to those rather than promising you turnaround times that are not ours to give.
Backup Power & Inverters services we provide in Tembisa
Load assessment
We measure what you actually run and tell you what it costs to keep each of it alive — before you commit to a system size.
Inverter installation
Correctly rated inverters installed with proper AC and DC protection, isolation and labelling.
Lithium battery banks
Battery sizing for real autonomy, with correct ventilation, mounting, fusing and communications to the inverter.
Essential-loads sub-board
A separate backed-up board so the circuits that matter stay live and the rest do not drain your battery.
Generator changeover
Manual and automatic changeover panels wired so that back-feeding into the network is impossible.
UPS for offices & equipment
Protecting tills, servers, access control, gates and medical or lab equipment through outages and dips.
Solar-ready installation
Systems wired so panels can be added later without replacing the inverter or redoing the board work.
Repairs to existing systems
Fault finding on inverters that trip, overheat, alarm or no longer charge, and replacing failed batteries.
What we see in Tembisa
Backrooms, tenants and shared boards
Where rooms are let out in Tembisa, one board frequently ends up feeding several households with no sub-metering and no clear split of circuits. It is a common source of both disputes and overloads. Separating the supplies properly costs less than most people expect and settles the billing argument permanently.
Business premises and trading hours
With the amount of commercial activity in Tembisa, a lot of our work here has to happen around someone's trading day. We schedule shutdowns outside business hours where we can, isolate only what we must, and keep the parts of the installation that pay the bills running while we work.
One fault, several unhappy neighbours
In blocks around Tembisa a single failing appliance can take out a shared earth leakage unit and put several units in the dark. Isolating that means testing unit by unit rather than guessing, and it is far quicker when the building has a current circuit schedule — which is something we leave behind whenever we work on a common-property board.
The compliance side, explained plainly
Two documents decide whether a solar or inverter installation in Tembisa is legal, insurable and safe to leave running. Most of the complaints we are called in to fix come down to one of them being missing.
An electrical Certificate of Compliance
Required for every solar or inverter installation regardless of size, because connecting one alters your electrical installation. It is also the first document an insurer asks for after a fire or lightning claim. Only a registered person may issue it, and only after testing the installation.
SSEG registration with Eskom and Ekurhuleni Energy
Any system connected to the grid — even one that never feeds power back — must be registered as small-scale embedded generation with your supply authority. Registration needs a compliant inverter, a single-line diagram and your COC. A genuinely off-grid system with no grid connection does not need registration, but still needs a COC.
Municipal fees, timelines and any registration amnesties change regularly. We confirm the current position with Eskom and Ekurhuleni Energy as part of every quote rather than quoting you last year's rules.

Backup Power & Inverters in Tembisa — your questions answered
What can I run on an inverter in Tembisa?
That depends entirely on size. A modest system comfortably covers lights, Wi-Fi, TV, gate motor, alarm and a fridge. Geysers, stoves, kettles, tumble dryers and pool pumps are heavy loads that push you into a much larger and more expensive system — we will show you the numbers either way.
Does an inverter installation need a COC?
Yes. Connecting an inverter alters your electrical installation, so it requires a Certificate of Compliance. Insurers routinely ask for it after fire or surge claims, and a system without one can leave you exposed.
Can I add solar panels later?
Yes, provided the inverter is chosen with that in mind. We size and wire systems in Tembisa so panels can be added without replacing the core equipment — worth doing even if solar is a year or two away.
How long do batteries last?
Modern lithium batteries are typically rated for thousands of cycles and come with multi-year warranties. Lifespan depends on depth of discharge, temperature and how the system is configured — a badly set-up system ages a battery far faster than the datasheet suggests.
Can you fix a system another company installed?
Yes. We inspect, test and report on what is there, then quote the corrective work. Common problems we find are undersized cabling, missing DC protection, no changeover and no certification.
Can you give me a price over the phone?
For standard items — a COC inspection, a board change, a standard point — yes, we can give you a realistic range immediately. For fault finding, nobody can honestly price a repair before they have found the fault, and anyone who does is guessing.
