Do Home Lifts Work in a Power Outage?

Do home lifts work during a power cut?

Yes — in the way that matters most. A home lift will not keep running normal trips on battery power, but almost every model sold in Australia is designed to get you safely to a landing and let you out when the mains supply drops. That is the job of the battery backup: not to keep the lift in service, but to make sure a power cut never leaves anyone stranded between floors.

The moment mains power is lost, an uninterruptible power supply (UPS) built into the lift takes over. It powers a controlled descent to the nearest landing, opens the doors, and keeps the cabin light, alarm, and emergency phone running. You walk out at a floor, not into a dark box halfway up a shaft.

Battery backup is a standard safety feature on residential lifts, not an optional extra. It is one of the core protections covered in our guide to home lift safety features, alongside door sensors, alarms, and emergency communication.

What happens if the power goes out while you are inside

Nothing dramatic. If you are in the car when the supply fails, the lift pauses for a moment, switches to battery, and then lowers itself slowly to the nearest landing under its own control. The doors open automatically and you step out. The whole sequence usually takes less than a minute.

No action is needed from you. There is no crank to turn and no lever to find. The cabin light stays on throughout, and if anything does go wrong, the emergency phone connects you to help.

How battery backup and emergency lowering work

The battery backup is a small sealed battery pack, kept charged from the mains, that sits in the lift controller. Lift makers call the controlled descent automatic emergency lowering, or automatic rescue.

On a hydraulic home lift, lowering is simple: a valve releases pressure gently and gravity brings the car down while the battery powers the controls and door. On a traction or screw-drive lift, the battery instead drives the motor at low speed to move the car to a landing. Either way, the descent is slow and controlled by design.

Three functions are kept alive that matter in a blackout: the cabin light, the alarm button, and the emergency phone or intercom. Under AS/NZS 1735.18:2002 — the Australian Standard for lifts in private residences — a home lift must provide for emergency operation and communication, which is why these functions are engineered to survive a power loss.

How long does the battery last?

Long enough for the job, with margin to spare. The backup is sized for rescue, not for a full day of trips. As of 2026, a typical home lift battery will complete the emergency lowering cycle and then keep the light, alarm, and phone running for a period measured in hours, not minutes — commonly rated for several emergency descents on a single charge.

Batteries wear. A backup battery generally needs replacing every three to five years, and checking it is a routine part of servicing. To see where standby power sits in the wider budget, our guide to home lift running costs breaks down electricity, servicing, and battery replacement.

Can a home lift run on a generator or solar?

It can, and for outages that last hours rather than seconds this is the real way to keep a lift in full service. A home lift draws modest power — most residential models run on a standard single-phase supply — so a suitably sized backup generator or a home battery system can keep it operating normally through a longer blackout.

Two options are common. A whole-of-home battery, paired with rooftop solar, will run the lift as just another appliance for as long as its charge lasts. Alternatively, a standby generator wired through an automatic transfer switch starts when the grid drops and carries the lift along with the rest of the house. Either approach is worth raising with your installer at the quoting stage, especially if you rely on the lift daily or live where outages are common. Compact residential models, including the small lifts for homes that suit tight footprints, are generally the easiest to back up this way because of their low power draw.

What this means for your safety

The blackout fear is understandable, and the answer is reassuring: a properly specified and maintained home lift will not trap you when the power goes out. The battery backup exists precisely so that a mains failure ends with you standing on a landing, not waiting for rescue. Keep the backup battery on its replacement schedule, test the emergency phone as part of routine servicing, and the protection stays in place.
