What happens to a home lift when the lights go out?
If you're weighing up a home lift for a Ghanaian household, this is usually the first real question, even if it isn't always asked out loud.
The worry is a fair one
Dumsor has taught most Ghanaian households to plan around the power going out without warning. So it's entirely reasonable to picture the worst version of a home lift: someone mid-floor, the cabin stopped dead, no way down until the grid comes back. That fear is exactly why a lift built for Ghana has to answer this question before any other.
The answer: gravity, not electricity, brings you down
A Nibav home lift doesn't hang from a cable or push up on hydraulic fluid — the cabin rises and falls because of a change in air pressure inside a sealed cylinder. That matters here because descent doesn't depend on the motor running. If mains power cuts out at any point, the cabin simply floats down on gravity to the ground floor, and the doors can be opened as normal.
You are never trapped between floors by a power cut.
Battery backup covers the rest
While the cabin itself doesn't need power to descend, a few things still benefit from staying on during an outage — so a backup battery keeps the cabin lights, fan, alarm, and GSM communication running for roughly 30 minutes. That's enough time to complete the descent comfortably and stay in contact if needed, without the cabin ever going dark or silent.
It runs on the power you already have
A Nibav lift is designed around single-phase household supply · zero power on descent — the same single-phase circuit already feeding most Ghanaian homes. There's no need for a three-phase upgrade or a dedicated transformer.
- Going up draws power comparable to a large home appliance — nothing your existing wiring can't handle.
- Coming down uses almost no power at all, since gravity is doing the work.
- It runs comfortably on an inverter or solar setup, and on a household generator — the kind of backup arrangements already common in Ghanaian homes.
How this compares to a conventional lift
Conventional hydraulic and traction lifts weren't designed with Ghana's power reality in mind. Here's how the two approaches differ.
| Nibav vacuum home lift | Conventional hydraulic / traction lift | |
|---|---|---|
| Electrical supply needed | Single-phase household supply | Three-phase supply, often a dedicated feed |
| Machine room | None — the turbine sits on top of the cylinder | Separate machine room usually required |
| Hydraulic fluid | None — the system runs on air, not oil | Hydraulic oil reservoir, subject to leaks and servicing |
| Backup power cost | Small backup battery built in for lights, fan, alarm, comms | Larger UPS or generator transfer often needed to ride through outages |
| Behaviour during an outage | Cabin floats down on gravity to the ground floor | Typically stops in place until power or backup is restored |
