How to Manually Update UGREEN UPS Firmware in UGOS Pro

Updating UGREEN UPS firmware manually is a short process, but the prerequisites matter: you need an official UGREEN UPS, a supported UGOS Pro version, the correct firmware package for your UPS model and enough battery charge to complete the update safely.

This guide shows you how to download the correct firmware, run the manual update in UGOS Pro and restart the UPS and NAS in the required order. If you want to understand why a UPS matters during an outage, see our guide to what to do after a NAS power outage.

Quick Guide: How to Update UGREEN UPS Firmware

Before You Start

Applicable Version: UGOS Pro version 1.14.10.0037 or above.

Interface note: Screenshots and interface labels in this guide are for reference only. The actual display may vary depending on the system or application version, so follow the interface shown on your device if minor differences appear.

• This tutorial applies only to official UGREEN UPS devices.
• Make sure the UPS is properly connected to the NAS and successfully recognised by UGOS Pro before starting.
• The UPS battery must be at least 50% before a manual firmware update can begin.
• Obtain firmware files only from the UGREEN Download Center or official UGREEN technical support channels.
• Do not use firmware from unverified sources, and do not disconnect the power or communication connection while the update is in progress.

If you are using a third-party UPS, contact the manufacturer to confirm whether firmware updates are supported and how they should be performed.

How to Download UGREEN UPS Firmware

Before starting the update in UGOS Pro, download the firmware package for the exact UGREEN UPS model you are using.

Prerequisite: Make sure your NAS is connected to the UGREEN UPS through the UPS communication cable and that the UPS appears correctly in UGOS Pro.

1. Visit the official UGREEN website and open the UGREEN Download Center.
2. Under Select model, select UPS. Then choose the UPS model you purchased from the product model list to open its dedicated page, for example US3000.

3. On the corresponding firmware download page, click Download.

4. Save the latest UPS firmware file to your local computer. UGREEN UPS firmware is typically provided in .bin format.

Before moving on, confirm that the downloaded file is intended for your exact UPS model. Using the wrong firmware package can prevent the update from completing correctly.

How to Manually Update UGREEN UPS Firmware in UGOS Pro

1. Log in to UGOS Pro and open Control Panel > Hardware & Power > UPS.
2. Confirm that the system has successfully detected the UGREEN UPS device. The interface should display information such as the current battery capacity and remaining available time.

3. In the UPS information section, locate Current firmware version and click Manual update.
4. In the pop-up window, click Browse, select the .bin firmware file you downloaded and click Confirm to begin verification and the firmware update.

Important: Do not operate the device or disconnect the UPS power or communication connection while the firmware update is running. Wait for UGOS Pro to indicate that the update has completed successfully before moving to the restart procedure.

Restart the UPS and NAS After the Update

After the firmware has been successfully updated, restart the UPS and NAS in the following order so the new firmware can take effect properly:

1. Shut down the NAS properly.
2. Unplug the UPS power cord from the AC outlet.
3. Press and hold the power button on the UPS to turn it off completely.
4. Wait a few seconds, reconnect the UPS power cord and press the power button to turn the UPS back on.
5. Once the UPS has started normally, power on the NAS.

UPS Button Operations

• Power on / Mute: Single press
• Power off: Press and hold for 10 seconds
• Enter power-saving mode: Double press

Check Your UPS Power Protection Settings

Once the UPS and NAS are back online, you can review the power protection settings in UGOS Pro. Depending on your setup, you can configure Auto Shutdown Mode or Standby Mode to respond after a custom time, when the UPS battery falls below 15%, or immediately. Auto Turn On can also allow the NAS to power back on automatically when mains power returns. Choose the settings that best match how you want your NAS to behave during and after a power outage.

Frequently Asked Questions

What should I do if the UGREEN UPS firmware update fails?

Make sure the firmware file is the original file provided by UGREEN, that the download is complete and that you selected the package for the correct UPS model. If the issue persists, contact UGREEN technical support.

Will updating the UPS firmware delete data from my NAS?

No. The firmware update applies to the UPS module and does not modify data stored on the NAS. However, do not interrupt the firmware update or disconnect the UPS while the process is running.

Why can’t I start a manual UPS firmware update when the battery is low?

The UPS battery must be at least 50% before the manual firmware update can start. If the battery level is below 50%, allow the UPS to charge and try again once it reaches the required level.

Can I use firmware for a different UGREEN UPS model?

No. Download the firmware for the exact UPS model you are updating. If you are not sure which package applies to your device, check the model in the UGREEN Download Center or contact UGREEN technical support before starting the update.

Conclusion

Keeping UPS firmware current is part of maintaining a reliable power-protection setup for your NAS, not simply a one-off update task. The key is to treat firmware changes as controlled maintenance: use only model-specific files from official UGREEN sources, perform updates when the UPS is in a stable state, and keep track of the firmware version you are running. If an update behaves unexpectedly, avoid trying different firmware packages at random and check with UGREEN technical support first.
