A backup system is only as safe as its wiring. Cheap installations in Pretoria Central routinely skip the essential parts: correct changeover, DC protection, ventilation and earthing. We install systems that pass inspection and keep working.
Pretoria Central is the capital’s inner city — government precincts, university campuses, embassies and high-density residential blocks, much of it on older distribution infrastructure. 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.
Supply in Pretoria Central comes through City of Tshwane Electricity. If your whole street is dark, that is a network issue and we will say so. If it is only your property, the fault is inside your installation and that is exactly what we are here for.
Backup Power & Inverters services we provide in Pretoria Central
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 Pretoria Central
Compliance that someone will eventually ask for
Landlords, insurers and lease renewals in Pretoria Central all eventually ask the same question: where is the current Certificate of Compliance, and does it cover the work the tenant did? Getting that documented while the premises are trading normally is considerably cheaper than assembling it under pressure after an incident.
Apartment blocks and shared supply
Multi-unit buildings in Pretoria Central bring their own problems: shared risers, common-property boards, sub-metering disputes and faults in one unit that trip another. Work in these buildings needs coordination with the managing agent or body corporate, and clear documentation of where the fault actually was.
The compliance side, explained plainly
Two documents decide whether a solar or inverter installation in Pretoria Central 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 City of Tshwane Electricity
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 City of Tshwane Electricity as part of every quote rather than quoting you last year's rules.

Backup Power & Inverters in Pretoria Central — your questions answered
What can I run on an inverter in Pretoria Central?
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 Pretoria Central 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.
Is there a callout fee for Pretoria Central?
There is a callout and diagnostic fee for fault finding, which we tell you before we are dispatched. For quoted installation work the site visit is normally rolled into the quote. Either way you know the number before anyone gets in a vehicle.
