Correct Generator Sizing Before Buying

A generator should match the real load, starting currents, phase requirement, runtime target and site wiring. Keystone helps you avoid buying a generator that is too small, oversized, noisy or difficult to maintain.

Essential loadsLighting, IT, pumps, security, refrigeration and priority equipment.
Electrical integrationATS/AMF, changeover, earthing, cabling, protection and labelling.
Runtime planningFuel tank size, operating hours, refuelling access and maintenance space.
Site conditionsNoise, ventilation, dust, rain protection, exhaust routing and security.
Keystone does not keep diesel generators in stock. We size, specify, source and install according to approved project requirements.
Site planning

Backup Power That Fits Real Conditions

Generator work is not only about the machine. The installation must consider safe placement, electrical protection, transfer switching, fuel access, noise, ventilation and future maintenance.

  • Load shedding and voltage changes
  • Fuel storage, refuelling access and runtime expectations
  • Ventilation, exhaust routing, rain protection and noise control
  • Service access for batteries, oil, coolant, filters and testing

How a Generator Project Works

01

Site & Load Assessment

We check current loads, future growth, phase requirements and essential circuits.

02

Generator Selection

We recommend practical capacity, canopy, fuel tank, controls, ATS and protection.

03

Installation & Wiring

We plan cabling, changeover, earthing, exhaust, ventilation, labels and testing.

04

Commissioning & Support

We test start-up, transfer, protection, load behaviour, maintenance access and reporting.

ATS, AMF & controllers

Generator Controller & Transfer Support

For existing generators, Keystone can help with practical controller wiring, ATS/AMF issues, start/stop faults and upgrade planning.

ATS / AMF Wiring

Transfer switching, mains sensing, start signals, interlocks and control wiring.

Controller Replacement

Support for replacing outdated or failed generator controllers where suitable.

Fault Tracing

Start failures, alarms, shutdowns, sensor wiring and transfer problems.

Remote Alerts

Monitoring and alarm outputs can be considered where the controller supports it.

We can support selected controllers such as DSE, ComAp, SmartGen and similar units depending on model, condition, documentation and parts availability.

Maintenance contracts

Generator Maintenance Agreements

For sites that depend on standby power, a planned maintenance agreement is better than waiting for a breakdown. Keystone can support single generators or multiple site generators with routine checks and practical reporting.

  • Scheduled inspections, oil, filter, coolant and battery checks
  • Start tests, transfer checks and basic load behaviour review
  • Fault follow-up, recommendations and service notes
  • Priority support for agreed maintenance customers

Frequently Asked Questions

Keystone checks the connected loads, starting currents, phase requirement and runtime target before recommending a suitable generator size.

Generator cost depends on capacity, brand, canopy, ATS, delivery, installation requirements and site conditions. Keystone confirms pricing after sizing and quotation.

Yes. Keystone provides generator fault support and scheduled maintenance. Emergency call-outs depend on location, availability and the nature of the fault.

Yes. We can install and support ATS panels, AMF control wiring and changeover arrangements for suitable generator systems.

Many diesel generators require service based on running hours and manufacturer guidance. As a practical guide, routine checks should include oil, filters, coolant, batteries, belts, alarms, transfer operation and load behaviour.

We can work with many common generator brands, including Cummins, Caterpillar, Perkins, FG Wilson, SDMO, Kipor and other diesel generator equipment, depending on condition, serviceability and parts availability. This does not mean Keystone is an authorised dealer, distributor or registered vendor for those manufacturers.

Yes, we offer comprehensive annual maintenance contracts (AMCs) for organizations with single or multiple generators. Contracts include scheduled preventive maintenance, priority emergency response, and detailed service reports.

Yes. For suitable sites, generator backup can be planned alongside solar and battery systems so loads are protected more efficiently.

No, we do not service small petrol generators. Our expertise is focused exclusively on diesel generators and larger power solutions for homes, businesses, and industrial applications. For small petrol generators, we recommend contacting a local small engine repair shop.

We primarily serve Lusaka and surrounding areas for routine services. For larger projects and maintenance contracts, we also cover the Copperbelt, Livingstone, Ndola, Kitwe, and other major towns across Zambia.
