Set and Forget Backup Power

Unlike a portable generator, a home standby unit is permanently installed and switches on automatically, so you are covered even when you are not home.

Automatic Operation

Detects an outage and starts itself within seconds, restoring power without any manual setup.

Runs on Gas or LPG

Connects to your natural gas line or an LPG supply, so you never need to store or refill fuel.

10, 13 or 20 kVA

Choose the output that matches your home's size and the circuits you want to keep running.

Peace of Mind During an Outage

A home standby generator is installed by a licensed electrician alongside your switchboard, and monitors mains power around the clock. When an outage is detected, it starts automatically and transfers your home to generator power, then switches back once mains power returns. This means no more manual generator setup, no extension cords, and no gap in power to essential circuits.
