Whether you want to ride out an outage or run through a full day without supply, we size and install inverter and battery systems in Randburg that do exactly what you asked for — no more, no less.
Randburg is defined by a broad, mostly residential belt of 1960s–80s freestanding homes now mixed with townhouse complexes and busy neighbourhood retail strips, and the electrical work follows from that.
Electricity in Randburg is distributed by City Power. Your responsibility as the owner starts at the point of supply and covers everything inside it — the board, the circuits, the earthing and the fittings. That is the part we look after, and the part a Certificate of Compliance speaks to.
Backup Power & Inverters services we provide in Randburg
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 Randburg
Complexes, clusters and estates
Cluster and estate living is a defining feature of Randburg, and it changes how electrical work has to be handled. Supply often runs through common-property infrastructure, work may need body corporate or estate approval, and the boundary between the unit owner's responsibility and the scheme's is frequently unclear. We are used to working within those rules and to putting the responsibility split in writing before we start.
Fit-outs, tenants and handovers
Commercial space in Randburg changes hands often, and each tenant leaves something behind — a data run, an extra circuit, a sign supply nobody documented. When we take on a fit-out we establish what is actually there before adding to it, so the next handover is cleaner than the last one was.
Ageing wiring and original distribution boards
A large share of the housing stock in Randburg predates modern wiring practice. We regularly open boards here that still have rewirable fuses, no earth leakage protection, or earth conductors that were never properly bonded. Insulation on older cabling also goes brittle with age, which is why so many "sudden" faults in Randburg turn out to have been decades in the making.
The compliance side, explained plainly
Two documents decide whether a solar or inverter installation in Randburg 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 Power
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 Power as part of every quote rather than quoting you last year's rules.

Backup Power & Inverters in Randburg — your questions answered
What can I run on an inverter in Randburg?
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 Randburg 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.
