Uninterruptible Power Supplies of highest efficiency at 2024

[Kiriakos GR]

Just checked today due curiosity mostly,  Energy Star organization and their listed database.

In about 15 minutes of time, I did discover that since 2016, a new race started regarding Uninterruptible Power Supplies of highest efficiency.
Unfortunately for most consumers, the major race starts at models supporting 3000W or higher.

Energy Star, this is American certification, and most contenders are brands interested to conquer this market.

At smallest Wattage, 750W the winner is CyberPower - PR750ERTXL2U
Efficiency at 75% Load Min Config Lowest Dependency (ac): 98.6

At 3000W+ the winner is Minuteman - EXR3000RTHV
Efficiency at 75% Load Min Config Lowest Dependency (ac): 99.2


And here we have an example of how product marketing this distorts true test results. 
Tripp Lite - AGPS8294 : SUINT1000LCD2U
900W unit
Efficiency at 75% Load Min Config Highest Dependency (ac): 96.4
At their website they inform of Power Factor 1.0  ( zero losses )
