The 40 kVA Deutz diesel generator is a GenTech SA built power solution for standby, commercial and industrial applications. It combines the confirmed Deutz engine specification with SmartGen automatic control, a brushless AVR-regulated alternator and ATS / automatic mains-failure changeover included as standard. Faraday / Werna or equivalent quality is the standard alternator configuration, with Mecc Alte and Leroy-Somer available as quoted upgrades.
GenTech SA supplies the generator configured for mains-failure or solar-ready operation, with an automatic changeover switch included as standard, nationwide delivery options and commissioning support.

The correct 40 kVA generator depends on the connected load, starting current, operating pattern and installation conditions. GenTech SA can review motors, pumps, compressors, refrigeration, machinery, solar chargers and other equipment before finalising the Deutz generator configuration.
A 40 kVA Deutz diesel generator can be considered for appropriately sized workshops, commercial buildings, agricultural operations, machinery and standby-power applications. Final suitability depends on the real load profile and starting requirements.
ATS / automatic changeover is included as standard for mains-failure operation. Where required, the generator can also be configured to work with a solar and battery system when the site controller calls for generator support or battery charging.
GenTech SA supports supplied generator sets with scheduled servicing, repairs, fault finding, replacement parts and technical assistance. Long-term support and serviceability should form part of generator selection.
Generator sizing should consider both running kW and starting demand. Motors, pumps and compressors can require significantly more power during starting, while altitude and power factor can reduce available operating margin.
Deutz-powered generator sets can be supplied with sound-attenuated or alternative enclosure configurations depending on the project. Canopy design, ventilation and access arrangements can vary according to generator size, application and availability.
GenTech SA welcomes generator delivery enquiries throughout South Africa and selected African export markets. Transport, off-loading and installation requirements are confirmed according to the destination and project scope.
Yes. GenTech SA includes ATS / automatic mains-failure changeover as standard on the generator build.
Yes. It can be configured for solar-backup operation where the site control system calls the generator to support the load or battery charging when required.
That depends on running load, motor and compressor starting current, operating hours, altitude, power factor and site conditions. GenTech SA can review the application before quotation.
Yes. Nationwide delivery enquiries are welcome, and selected export requirements can also be quoted.
