GenTech SA supplies the 40 kVA John Deere diesel generator around the confirmed PowerTech engine specification and the requirements of the application. Correct sizing should consider running kW, starting current, power factor, altitude, operating hours and the equipment that must remain powered during an outage.
Small business, retail, offices, farms, residential and light commercial standby applications where the calculated load fits this output class.
ATS / automatic changeover is included as standard for mains-failure operation. The generator can also be configured for solar-ready operation where a site control system calls the generator for load support or battery charging.
GenTech SA supports supplied generator sets with scheduled servicing, repairs, fault finding, replacement parts and technical assistance after delivery.
Generator selection should consider running load and starting demand. Motors, pumps, compressors and machinery can require substantially more power during starting, while altitude and power factor can reduce operating margin.
Faraday / Werna or equivalent quality is the standard alternator configuration, with Mecc Alte and Leroy-Somer available as quoted upgrades. Enclosure and project-specific arrangements can be considered according to the application.
GenTech SA welcomes John Deere generator enquiries throughout South Africa and selected African export markets. Transport, off-loading and project requirements are confirmed according to destination and scope.
Yes. GenTech SA includes ATS / automatic mains-failure changeover as standard on the generator build.
Yes. It can be configured for solar-ready operation where the site control system calls the generator to support the load or charge batteries when required.
