- Converts AC power from the mains to DC power and then back to AC power, but only when the mains power fails—also, converter AC to DC power for charging the battery when mains power is present.
- This means there is no switching delay when the mains power fails, but the lift will continue to operate smoothly without any jerk or interruption.
- Lift inverters are typically more efficient than online UPSs, as they only convert power when needed. This saves a lot of power compared to the Online UPS as Online UPS continues to draw extra power when Mains is present for converting it into AC to DC and then AC again.
- Lift inverters are also typically more compact and lightweight than online UPSs.https://www.kunwersachdev.com/thoughts/personal/lift-inverter-as-a-power-backup/11/
- Lift Inverters nowadays, called Emergency rescue Devices, have the option of working on a Lithium battery and can provide a backup time of up to 3 days. They can replace Generators and can save pollution.
- The lift Inverter or ERD can run on Solar power to save the grid power and make the environment green.
- The IOT feature enables the control of the Lift Inverter through Bluetooth, Wi-Fi and GSm to control and monitor the parameters of the Lift Inverter/ERD and control them remotely through the mobile application.
- Converts AC power from the mains to DC power and then back to AC power continuously, even when the mains power is available.
- This means that the lift always operates on clean, regulated DC power, regardless of the quality of the main power.
- Online UPSs have no switching delay, so there is no jerk or interruption when the mains power fails.
- Online UPSs are typically less efficient than lift inverters, as they constantly convert power.
- Online UPSs are also typically larger and heavier than lift inverters.https://en.wikipedia.org/wiki/Uninterruptible_power_supply
Comparison of Lift Inverter and Online UPS for lift back up

|very limited by Lead Acid battery size
Which one is better for lifting back up?
It depends on the specific requirements of the lift installation. If the lift is in a critical location, such as a hospital or a high-rise building, an online UPS may be the better choice, as it will provide the most reliable and uninterrupted power supply. However, a lift inverter may be a better option if the lift is in a less critical location or if cost is a major factor.
- Lithium batteries: Lift inverters can be powered by lithium batteries, which are more efficient and have a longer lifespan than traditional lead-acid batteries.
- Remote monitoring: Some lift inverters and online UPSs offer remote monitoring capabilities, which can be useful for monitoring the system’s health and receiving alerts in case of problems.
- Warranty: Some lift inverters and online UPSs offer longer warranties than others.
Both lift inverters and online UPSs can provide reliable backup power for lifts. The best option for a particular installation will depend on the lift’s specific requirements and the available budget.
