The UPS Score assessment evaluates the relative ranking of a UPS based on its state. The score is between 0 and 100, with 100 being the best possible score.
How is the Score calculated and reflected?
The score calculation is based on anonymous benchmarking of the following factors against comparable devices:
- Temperature of the battery
- UPS Age
- Battery Age
- If the UPS has either a Critical Alarm or a Lifetime Alarm, indicating end-of-life for the device
- Unbalanced, for a 3-phase UPS, where the phases are not equally balanced
The scores are evaluated as being either:
Poor (0-33) displayed in red
Average (33-66) displayed in orange
Good (66-100) displayed in green
On the Assessments page, a quick insight into the distribution of assessed devices is indicated in the UPS Score.
Recommendations based on the score
Based on a factor in a score with a poor evaluation, a related recommendation is given. For example, if a battery is old, there is a recommendation to replace the battery.
On the UPS Score page, you can filter for a specific score or recommendation.
Recommendations appear on every tab in the UPS Score details page.
Since a significant change to any of the factors of the score will impact and update the score for the UPS, there is a dedicated view for all the significant changes that influenced the score on the Changes tab of the UPS Score details page.
Note: Data quality improvements in the March 8, 2020 release generate a more precise UPS score. As a result, you might see a change in your UPS score.
Critical and lifetime alarms that impacted the score are displayed on the Alarms tab, with the title, description, and general information about the duration.
The latest addition to the UPS Score is an extension of the battery information, with details about the wear of the battery.
Tip: IT Expert Administrator users can now update the Last Battery Replacement date on a single device. See Single device configuration
Battery wear information is currently available for:
- Single phase Smart-UPS
- 3-phase Smart-UPS
- Single phase Galaxy UPS
- Some 3-phase Galaxy UPS only Supported Galaxy 3-phase UPSs
- Symmetra UPS Supported Symmetra UPSs
Note: UPSs with lithium batteries are not included in the UPS assessment at this time.
The Battery wear tab contains three segments of information related to the wear.
- Battery details indicates the current wear of the battery. When the wear is beneath the recommended threshold of 40%, the wear is indicated in red. The wear also indicates an expected end-of-life (EEOL) year and month for the battery. If the temperature of the battery is not optimal (25°C / 77 °F), an additional expected end-of-life at ideal temperature is given if there is at least one month of additional lifetime for the battery.
- Main factors of wear indicates the impact of the three factors that contribute to the calculation of the battery wear: Temperature, Age, and the cumulative count of registered discharges (cycles).
- Health projection is a projection of the decay of the battery over the time it has been monitored. The graph includes both the EEOL and the EEOL at ideal temperature, if present.
UPS Score details page on the Battery tab indicates a battery wear beneath the threshold of 40%
In case of available battery wear model data, the first tab will be extended with the battery health wear in percent.
What does this mean for you?
The UPS Score assessment gives you insight into your UPS using a score calculated against comparable devices.
You can use the score as an indication of how close the components, or the device itself, is to its end-of-life, and determine whether the device is being used in a optimal way.
Life expectancy can vary greatly depending on factors such as whether you proactively perform routine maintenance.
The UPS Score assessment gives the most accurate indication of the state of your hardware when you're using the latest Gateway version and a self-test has been run on the UPS.
