What’s the difference?
Standby & Prime Power Generators 

Standby Power refers to generators that are ready to provide electrical power during an emergency situation such as a power outage.  These ‘back-up Generators’ switch on as soon as the standard utilities go down on your home or cottage. When the ‘utility power’ comes back on, an automatic switch transfers power back to normal services and the generator goes back into ‘standby mode’ – ready for the next outage!

Prime power refers to generators used to provide power continuously as the main power source not just back-up power.  Prime Power is often used when other utilities are not available such as remote areas where the grid is not accessible.

If you are looking for a generator on your Home/cottage/ small building etc.,
‘Standby Power’ should be Right for you!

These units are usually ‘air-cooled’, run by natural gas or propane,
installed permanently outside of the building.

Fully customizable for your home and power needs.
Generators range in sizes from approximately 7 kW to 22 kW.

The smaller units are usually installed to cover ‘essential services’ like the sump pump, furnace, water pump, etc.

The larger units can be installed with a ‘whole home’ transfer switch
so that you don’t have to pick the circuits/items you want covered.
(Power is still limited to size of generator)
