We install and repair backup power across Westonaria: new inverter systems, battery replacements, generator changeover panels, and rescuing installations that were done badly the first time.

Known for a deep-level mining town on the far West Rand, serving mine operations, contractor yards and surrounding residential areas, Westonaria keeps our teams busy across every kind of installation from single plug points to three-phase distribution.

Westonaria sits within Rand West City Local Municipality, with Rand West City and Eskom (supply area varies) as the supply authority. Any work that changes your connection — a capacity increase, an embedded generation system, a new connection — goes through them, and we prepare the documentation that process requires.

Backup Power & Inverters services we provide in Westonaria

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 Westonaria

Loads that punish a weak connection

Motors, compressors, welders and refrigeration plant in Westonaria draw hard on start-up and expose every marginal termination in the installation. A connection that is merely tight enough will survive a domestic load for years and fail on a factory floor in months, which is why thermal scanning under load finds problems that a visual inspection never will.

The compliance side, explained plainly

Two documents decide whether a solar or inverter installation in Westonaria 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 Rand West City and Eskom (supply area varies)

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 Rand West City and Eskom (supply area varies) as part of every quote rather than quoting you last year's rules.

Backup Power & Inverters in Westonaria — your questions answered

What can I run on an inverter in Westonaria?

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 Westonaria 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 Westonaria?

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.
