Frequently asked questions

Answers are plain text on the page for search engines and buyers alike.

What will a 150 kVA generator actually run?

At about 120 kW of prime power, this unit covers mixed commercial loads — lighting, HVAC packages, refrigeration, lifts and IT — provided the largest motor starts are within the set’s surge capacity. We size final selections against your measured or estimated load profile.

Is installation included with the 150 kVA Three Phase Silent Diesel Generator?

Supply can be unit-only or turnkey. SANS 10142-1 compliant installation, AMF integration and a Certificate of Compliance on handover are available nationwide. Ask for a site-specific quote.

How noisy is the silent canopy?

This set is rated at approximately 74 dB(A) at 7 m under standard test conditions. Site layout, barriers and load profile affect the figure you hear on the ground.

Standard cover is 24 months. Genuine Cummins and alternator parts are held for common service intervals, with regional breakdown response across Southern Africa.
