When the grid is down for hours and batteries are running low, a reliable generator with a safe changeover is the simplest way to keep business moving and the house comfortable. We install and integrate generators in Harare for homes, shops, offices, workshops and clinics — with clean wiring and a neat finish.
Our approach is practical: the right generator size, a compliant manual changeover or ATS (automatic transfer switch), proper earthing and surge protection, and a tidy handover anyone can use. No back-feeding ZETDC. No risky “DIY” cross-wiring. Just safe, dependable power when you need it.
We’ll help you choose petrol vs diesel, single-phase vs three-phase, quiet/enclosed vs open-frame — based on your actual loads: fridges and freezers, point-of-sale, security, pumps, servers, medical or workshop equipment. We aim for enough capacity to run essentials without abusing the generator.
Already have a generator that “sort of” works? We can rewire it correctly, add a compliant changeover, fix earthing, tame messy cabling, and label circuits so everything makes sense. We’ll also test under load and show you how to operate it confidently.
Safety matters. Generators produce high voltages, carbon monoxide and heat. We ensure proper placement, ventilation, fuel storage practices, earthing, RCD protection where required, and surge protection for sensitive electronics. Your system will be safe, neat and documented.
From Borrowdale and Mount Pleasant to Avondale, Highlands, Greendale, Marlborough, Westgate and the CBD — our Harare electricians install and commission generator systems that just work.
FAQs
1) Do I need a changeover switch or an ATS?
A manual changeover is affordable and reliable — you flip the lever to select ZETDC or generator, with no chance of back-feeding. An ATS does it automatically when the grid fails and restores when power returns. For homes and small offices, manual is often perfect. For shops, clinics and servers, an ATS is convenient and reduces downtime.
2) What size generator do I need for a typical home?
Most Harare homes run comfortably on 5–8 kVA for essentials (lights, plugs, fridge/freezer, TV, Wi-Fi, gate/garage, small pumps). Add borehole pumps, large ovens, welders or multiple geysers and you’ll need more. We’ll measure/estimate your startup currents and recommend a size that won’t struggle or burn fuel unnecessarily.
3) Petrol vs diesel — which is better?
Petrol units are cheaper upfront and fine for light-to-medium use. Diesel units cost more initially but handle heavier loads for longer hours, often with better fuel economy and longevity. We’ll suggest the best option for your runtime, budget and load profile.
4) Will a generator damage my electronics?
Not when it’s installed correctly. We wire a compliant changeover, set up proper earthing, and recommend AVR/inverter-type generators where needed. We also advise on surge protection and safe startup/shutdown sequences to protect TVs, point-of-sale, routers, CCTV and computers.
5) Can you integrate a generator with my inverter system?
Yes. We can configure the generator to charge batteries and/or power loads via your inverter/DB — with correct priorities, breakers and protection. The goal is smooth handover without tripping, nuisance alarms or overloading.
6) How noisy will it be — and where should it go?
Open-frame units are louder and should sit outside in a ventilated, weather-protected spot away from doors/windows. Enclosed/silent units reduce noise significantly. We’ll advise on safe siting, anti-theft measures, exhaust direction and rain protection to extend lifespan and keep the family/neighbours comfortable.
