The Bison Whisper Standby Generator is a portable, air-cooled, 499cc, 6.5kVA diesel generator ideal for powering your home or a small business. As a backup power generator, it is the perfect machine to run your domestic household appliances during a power cut or outage.

The 12 litre tank will easily run for up to 12 hours at around 50% load, making this Bison generator ideal for all sorts of applications; such as domestic supply, catering, construction use and a source of power in an emergency. It is supplied with a wireless remote control allowing you to start up the machine from up to 100m away; perfect for those cold mornings on-site or from the comfort of your home.

The AVR alternator ensures that the power produced is stable and safe to use with any domestic electrical appliance in your home or business. The additional option of a Capacitor Smoothing Pack smooths out the current making the DSG entirely suitable for highly sensitive equipment, such as computers.

The Bison Whisper Standby Generator is designed for standby use. For a continuous power supply, we recommend a 1500rpm diesel generator.

*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.
