  1. Does the price include installation? No, the price doesn't include installation. Installations are all different and require varying length of cable, time and distances to be travelled. In addition to this installations need to be done by a qualified electrician to issue a valid Certificate of Compliance (COC) for your insurance. 
  2. Do we offer installation? No, but we do have recommended installers who will be able to assist you with your installation and sizing your generator.
  3. Does the price include delivery? All prices exclude delivery. Delivery is charged extra based on the distance and complexity of the delivery.
  4. Do I need anything else to connect the generator? Yes, you'll need either an Automatic Transfer Switch (ATS) or Manual change over switch in order to link the generator into your property's electrical distribution board. This is required by law to ensure that the generator and mains supply are adequately isolated from one another.
  5. What size ATS do I need? The recommended size ATS is based on the size of the generator, not the mains incoming supply. The ATS should be capable of taking the whole load from either mains or the generator as both will pass through the ATS switch. Therefore, whilst the recommended switch size will be correct for most installations, it may not be correct for your installation. You should ensure that an electrician performs a load test and checks this information.
  6. Tell me about the Warranty? The warranty is 12 Months or 1000 Hours whichever occurs first. It is a limited warranty. Travel to site is not included in the warranty. The goods need to be returned to the OEM located in Johannesburg, Nelspruit or Pietermaritzburg. Please refer to the Terms and Conditions of sale and the Warranty Card for further information on the warranty. Warranty is held with the agency where you bought the generator. If you have purchased your generator in Johannesburg then the warranty is held in Johannesburg etc.
  7. How long is this price valid? Pricing is valid whilst stock lasts and is subject to change without prior notice. Pricing on the website is indicative and should always be confirmed by Generators4Africa in the form of a written quotation.


PLEASE NOTE: ALL ratings are approximate and at SEA LEVEL. Engines need to be de-rated for altitude. A rough guide to de-rate performance is 1% for every 100m above sea level. I.e: A 20kVA at sea level is an 18kVA at 1000m above sea level (10% less) etc.

The generator will not be able to take the full load instantaneously. The load should be added to the generator gradually. 50% initially and then stepped up over time once engine is up to temperature.
