4 level modularity for maximum flexibility

Its modular design allows easy system resizing by addition of power modules. Maintenance operations can be done without powering down the system and without switching to bypass line.

Continuous savings

Certified maximum efficiency in all modes of operation: 96% in double conversion mode, thanks to patented Green Conversion technology, 97% in active filtering mode, 98% in ECO mode and 99.5% in UHE mode. With smart-parallel control unnecessary modules are switched off to further enhance system efficiency

Low environmental footprint

UPSaver® can feed at maximum efficiency any load up to unit power factor and its transformer-free design makes it lighter and more compact for a higher environmental sustainability.


4 UPS in one for maximum versatility

UPSaver® can operate in all International Electrotechnical Commission classified modes of operation: double conversion (VFI), active filtering (VI), ECO mode (VFD) and Ultra High Efficiency (VFD).

Low maintenance cost

Green Battery Management and Green Conversion technology save battery life, by mitigating the major root causes of battery ageing, such as ripple current and floating charge micro currents. UHE mode of operation dramatically increases the duration of wearing components.

Maximum safety

    UPSaver® comes with both detection circuitry and input terminal disconnection contactor for maximum operator safety.


UPSaver® is based on 100 kW or 200 kW unit modules and an I/O module for cable connection, system bypass and user interface. Unit modules have removable sub-modules for easy maintenance and low MTTR.


Configuration options include N+R redundancy, distributed and centralized static bypass.


The I/O module is designed to allow unit modules hot connection and disconnection without switching to bypass line.


Users can set any of its 4 modes of operation or activate UPSaver® strategy algorithm, which dynamically sets the best one according to mains conditions, to provide critical loads with high quality power at the highest efficiency.


Unit input power factor, input THDi <3%, programmable soft start and hold-off features make UPSaver® your Genset’s best friend.
