Key Features

Robust, practical and reliable diesel generator. Whether it’s for use as a standby or backup generator, or for prime running on a construction site, this is engineered to do the job. Designed by the technical team here at OMC specifically for demanding New Zealand conditions. Every feature is intentional: like the silent canopy made from fully galvanised sheet with heavy duty 120µm powder coating, or the bunded fuel tanks that come standard for safety and environmental protection. Fitted exclusively with Deep Sea Electronics controllers, for the ultimate in reliability. To maximise protection, we opted for marinized, triple-dipped LeRoy Somer Alternators to make these seriously robust.
The ST165C5 is suitable for a wide range of applications from backup or standby applications to construction sites, events, or farming. With a 4 Pole AVR Controlled alternator this provides mains quality power, ensuring your electronics are safe. This is also suitable to charge battery energy storage systems such as those connected to solar panel systems.
