A lift inverter, also known as an elevator inverter or elevator UPS, is a device that provides backup power to an elevator in the event of a power outage. It does this by converting DC power from batteries into AC power and converting the AC power to DC power to charge the batteries. It can run the elevator/lift motor and a complete lift on the battery power. The same device also charges the batteries.
The Lift Inverter/ERD (Emergency Rescue Device) has the potential to be a significant technology for lift backup, offering several advantages over traditional methods like generators or UPS systems. Here’s why:
Benefits of Lift Inverter/ERD:
Uninterrupted operation during power outages: The main advantage is ensuring smooth lift operation even during power disruptions. This prevents people from getting trapped and minimizes inconvenience, especially for those with accessibility needs.
Faster switching time: ERD boasts near-instantaneous switching between mains and battery power (less than three milliseconds), avoiding noticeable interruptions or jolts in the lift movement. So lifts work uninterruptible in case of power failures.
Safety features: ERD systems often integrate features like automatic floor-leveling and door opening in case of power failure, further enhancing passenger safety.
Environmental benefits: Unlike generators, Lift Inverters/ERD systems are quieter and produce no emissions, making them a more sustainable option.
Because of instant backup in case of power failure, lift failures become almost 10% higher compared to the inability of lifts when the lift inverter is not installed.
The latest Lithium battery system makes the Lift Inverter system compact, and the life of the batteries increases three times compared to Lead-acid batteries used for backup power.
The latest Wi-Fi-based monitoring and controlling features make them very tech savvy, and lift maintenance data can be captured online and helps to maintain lift maintenance on time.
However, it’s essential to consider some limitations:
Higher initial cost: As mentioned, the initial installation cost of ERD systems might be higher than alternatives like generators.
Battery capacity and charging time: The backup time depends on battery capacity, which might need to be scaled based on the building’s requirements and expected power outages.
Limited applicability: ERD systems are primarily suitable for smaller to medium-sized lifts. Large or high-rise buildings might require more robust backup solutions.
The Lift Inverter/ERD technology holds significant promise for the future of lift backup. Its safety, reliability, and sustainability advantages make it a compelling option for various building types and applications. However, it’s crucial to consider its limitations and suitability for specific needs before making an investment decision.
Can the battery Inverter/UPS operate the lift? Yes, lifts can work on inverters. Inverters are increasingly being used as a backup power source for lifts. Inverters convert DC power from batteries into AC power; These are 3-phase Inverters which can then be used to run the lift motor, which is also 3-phase operated. This allows lifts to continue operating even during a power outage. Nowadays, the Lift Inverter/Lift UPS is also called Emergency Rescue Device or ERD. https://suvastika.com/whats-lift-inverter/

The amount of time a lift can run on an inverter will depend on the size of the batteries and the load on the lift. However, most inverters can provide backup power for several hours.
There are several advantages to using inverters as a backup power source for lifts. First, Lift inverters/Lift UPS are more compact and quieter than diesel generators. Second, inverters do not produce emissions, which can be important in environmentally sensitive areas. Third, Lift Inverters/Lift UPS/ERD are more reliable than diesel generators and require less maintenance. https://www.saurenergy.com/solar-energy-news/solar-powered-centralized-off-grid-ups-for-lifts-in-multi-story-buildings
As a result of these advantages, inverters are becoming increasingly popular as a backup power solution for elevators. They offer a safe, reliable, and environmentally friendly way to keep lifts running during power outages.
Here are some of the benefits of using Lift inverters/Lift UPS/ERD for lifts:
Increased reliability: Inverters are more reliable than traditional diesel Generators, making them less likely to fail. This is important for lifts, as a failure in the power supply can lead
to serious injuries or even death.
No Switching Time: The Lift Inverter/Lift UPS/ERD has no switching time as it works seamlessly during the power failure, and no jerk or such feeling occurs. Lift operates uninterruptedly as if no power failure occurred.
Space saving: The new Lithium battery backup operated Lift Inverter/Lift UPS/ERD has saved space in the lift room and increased the life of Lift Inverters.
Improved efficiency: Inverters can help improve the efficiency of lifts as the maintenance of lifts goes down 50% as there is no stoppage of lifts due to power failure, which becomes the major factor of lift failures.
