Installation of Generator Sets

Compliant installation, done right

We do all our electrical generator installations to meet or exceed SANS regulations, and electrical compliance certificates are issued after installation. An automatic transfer switch ensures the generator goes online without any manual procedures.

All generator foundation requirements are designed by a practising civil engineer, and design drawings are supplied for any foundation work.

Service of Generator Sets & Repairs

24/7 service & breakdown support

Our electromechanicians are highly skilled, qualified and experienced. We source spare parts only from the original generator manufacturer. All major breakdowns can be repaired on site or at our workshop, and our 24/7 standby team can attend to any mechanical or electrical breakdown.

Our technicians are qualified in both the mechanical and electrical fields — so you get the best of the two industrial trades involved in your generator installation. We offer standard service agreement contracts, with added options of diesel fill and a preventative maintenance programme.

FAQs

Frequently asked questions

Search or browse common questions about this service.

What backup power options do you install?
We install standby generators, inverter systems and battery backup — sized and integrated to suit your home or business needs and budget.
What is a changeover switch and do I need one?
A changeover switch safely transfers your installation between grid and backup power, preventing dangerous back-feeding. It's essential for a safe, compliant setup.
Can you size a system to my needs?
Yes. We assess which circuits and appliances you want to keep running and size the generator, inverter or battery system accordingly.
Is DIY generator connection dangerous?
Yes — connecting a generator without a proper changeover can back-feed the grid and endanger lives. Always have backup power installed by a qualified electrician.
Can backup power run my whole house?
It can, but it's usually more cost-effective to power essential circuits (lights, plugs, fridge, routers). We'll advise on the best balance for your budget.
Do you install inverters and batteries?
Yes. We install inverter and battery backup systems for quiet, automatic power during outages and load shedding.
Will the installation be compliant?
Yes — we integrate backup power safely into your DB board and can issue compliance certification for the work.
How long does installation take?
It depends on the system and your wiring. We'll give you a clear timeframe with your quote — many installs are completed in a day or two.
Can you wire only my essential circuits?
Yes. We can set up dedicated wiring so only your priority circuits draw from backup, maximising runtime.
Do generators and inverters need maintenance?
Yes — we offer servicing and support to keep your backup system ready and reliable when you need it.
How much does backup power cost?
It varies widely with the size and type of system. We provide a clear, no-obligation quote based on your needs.
Can you upgrade an existing backup setup?
Yes. We can improve, expand or make safe an existing generator or inverter installation.
What areas do you cover?
We serve the entire East Rand of Gauteng.
Do you offer free quotes?
Yes. All quotes are free and come with no obligation — just tell us what you need and we'll give you an honest price.
Are your electricians qualified and registered?
Yes. Our work is carried out and signed off by registered, wireman-licensed electricians who follow South African wiring regulations (SANS 10142).
Do you offer 24/7 emergency call-outs?
Yes — we provide 24/7 emergency electrician services across the East Rand for urgent faults such as power failures, tripping, sparking and burning smells.
Do you guarantee your work?
Yes. We stand behind our workmanship and use quality materials. If something isn't right with work we've done, we'll put it right.
How soon can you come out?
For emergencies we respond as fast as possible, day or night. For standard jobs we'll arrange a convenient time, often the same or next day.
What payment methods do you accept?
We accept common payment methods including EFT, and we'll confirm everything with your quote before any work begins.
