Standby Generators
Buy Standby Generators
Standby Generators are a critical buy for businesses, facilities, and operations that cannot afford unplanned power interruptions — including commercial buildings, data centres, healthcare facilities, manufacturing plants, and agricultural operations. Unlike portable generators, Standby Generators are permanently installed and configured to start automatically on grid failure, ensuring continuity of power with minimal delay. Wenbro supplies diesel Standby Generators across a range of kVA outputs to match the specific load requirements of your facility. For sites with lower or temporary power needs, our Silent Enclosed Generators or Open Frame Generators may be more appropriate. All units are supported by Wenbro’s in-house service team.

Frequently Asked Questions
What is the difference between a Standby Generator and a portable generator?
Standby Generators are permanently installed, connected to the building’s electrical system, and start automatically when grid power fails. Portable generators are manually operated and moved between locations. For critical facilities where power continuity is non-negotiable, a Standby Generator is the appropriate solution.
How quickly does a Standby Generator start when power fails?
Most diesel Standby Generators with automatic transfer switching (ATS) restore power within 10–30 seconds of a grid failure. The ATS monitors incoming supply and triggers the generator automatically, without requiring manual intervention. Contact Wenbro on 087 073 7777 to discuss ATS configuration options.
What size Standby Generator do I need for my facility?
Sizing depends on the total connected load you need to support during an outage — whether that’s the full facility or critical circuits only. Wenbro’s team can assist with load assessments to specify the correct kVA rating. Call 087 073 7777 for a consultation.
Are Standby Generators suitable for load-shedding applications in South Africa?
Yes — Standby Generators are widely used across South Africa to manage load-shedding in commercial, industrial, and agricultural settings. With automatic start capability and sufficient fuel reserves, they provide reliable power continuity throughout scheduled outages. Our Silent Enclosed Generators are also a popular choice where noise management is a requirement.
What maintenance does a Standby Generator require?
Standby Generators require regular servicing including oil and filter changes, coolant checks, battery testing, and load bank testing to ensure the unit will perform when needed. Wenbro’s in-house team provides scheduled maintenance plans for all Standby Generators purchased through us — call 087 073 7777 to arrange.
