The Bison Whisper is a portable, air-cooled, single-cylinder, 680cc, 10kVA diesel generator. It comes with either 240V single-phase only or 415V/240V three-phase and single-phase output. The generator is mounted in an acoustic cabinet resulting in noise reduction, approximately 20db lower than the Bison Mark II Generator.

The Bison Whisper 10kVA Diesel Generator has a 680cc electric-start diesel engine, which produces 15hp, and is fitted with a low oil pressure alert system that shuts down the engine automatically.

The Bison Whisper comes complete with a remote start/stop key fob, 12V battery charging output and modified AVR (Automatic Voltage Regulator) that reacts to an inductive load, delivering a non-fluctuating current.

The Bison Whisper 10kVA Single-Phase Diesel Generator is ideal for running most of our Warrior single-phase machines and is also a powerful standby generator for the home to run household appliances during a power cut or outage.

The Bison Whisper 10kVA Three-Phase Diesel Generator is ideal for running most of our Warrior three-phase machines and can be used as a standby generator for a workshop to run machinery during a power cut or outage.


Three-Phase / Single-Phase Generator: 3P socket – 10kVA / SP socket – 3kVA.
Single-Phase Only Generator: 10kVA per individual socket but only 5kVA per socket if both are used simultaneously.

*We recommend purchasing the Automatic Changeover Switch. This unit can be wired into the Bison Whisper Generator. It will constantly monitor the mains voltage. If there is a power cut, the unit will start the generator and, after a few minutes, once the generator is warmed up, it will switch from mains to generator. Once the mains power has been restored, it will switch back from generator to mains and, after a few minutes, turn the generator off. This unit has a built-in battery charging circuit, which ensures the generator battery is always fully charged.

    Great customer service and back up


    I made a huge purchase in terms of money for a generator. All I can say is what a fantastic encounter I had. When I had issues, Warrior Welders replaced my unit within days without any hassle. Would I recommend them or use them again? It’s a huge yes…. This company actually has great customer service and back up. Thank you
