We Size the Generator Before You Buy
A generator should match the actual load, starting currents, backup priorities and site wiring. Keystone helps you avoid buying a generator that is too small, oversized, noisy, hard to maintain or unsuitable for your building.
| Site Type | Typical Loads | What We Check |
|---|---|---|
| Homes & Apartments | Lights, sockets, fridge, gate motor, router, pump | Essential circuits, noise level, placement, changeover and budget. |
| Offices & Shops | Computers, tills, routers, CCTV, printers, lighting | Business hours, phase requirement, ATS, surge loads and runtime. |
| Clinics & Schools | Lighting, ICT rooms, medical equipment, pumps, admin loads | Priority circuits, safety, fuel planning, maintenance access and noise. |
| Factories & Warehouses | Motors, compressors, pumps, lighting, offices, security | Starting current, load sequencing, three-phase balance and protection. |
| Critical Sites | Server rooms, telecom, access control, CCTV, fire systems | UPS bridge time, ATS timing, redundancy and maintenance response. |
Backup Power That Fits Real Site Conditions
Generator installations in Zambia need to consider load shedding patterns, fuel availability, dust, heat, rain protection, voltage changes, access for service teams and safe exhaust routing. We plan the full installation, not only the machine.
Tank size, consumption, refuelling access and operating hours.
Canopy type, neighbour impact, airflow, exhaust and security.
Earthing, changeover, ATS, protection, labelling and cable sizing.
Service space, battery checks, coolant, oil, filters and testing.

How a Generator Project Works
Site & Load Assessment
We check current loads, future growth, phase requirements and essential circuits.
Generator Selection
We recommend practical capacity, canopy, fuel tank, controls, ATS and protection.
Installation & Wiring
We plan cabling, changeover, earthing, exhaust, ventilation, labels and testing.
Commissioning & Support
We test start-up, transfer, protection, load behaviour, maintenance access and reporting.
Generator Controller Wiring & Upgrade Services
We specialize in wiring, installation, and upgrading of generator control systems. Whether you're working with modern digital controllers or restoring an older generator with analogue controls, our team delivers clean, standards-compliant wiring for optimal performance.
Controller Brands We Can Work With
Controller names are shown for equipment familiarity only. Keystone is not claiming authorised dealer, distributor, registered vendor or manufacturer-partner status for these controller manufacturers.
Upgrading Old Generators With Modern Controllers
Many older generators still operate with analogue or relay-based controllers. While these systems are simple and durable, they lack modern functions such as:
- Automatic Mains Failure (AMF)
- Remote monitoring & alerts
- Digital meter readings
- Engine protection & fault logging
- Safety shutdown features
- Load management & sync
What the Upgrade Involves
- Rewiring engine sensors (oil pressure, temperature, speed)
- Connecting alternator voltage/CT feedback
- Adding start/stop control circuits
- Configuring AMF/ATS functionality
- Setting up remote monitoring and alarms
The Result?
A generator that operates like new—with improved safety, better performance, and modern automation features. Give your old equipment a new lease of life with DSE, ComAp, SmartGen, or your preferred brand.
