Critical Power
UPS systems,0.7 kVA to9.6 MW+.
Vertiv UPS systems, battery plant and power protection in Angola — sized from a load survey, installed and maintained by certified engineers in Luanda.
Why UPS matters
Unstable supply is the leading cause of downtime.
Grid instability in Angola drives more unplanned outages than equipment failure does.
Damage happens long before the lights go out.
Voltage sags, harmonics and transients degrade equipment continuously and invisibly.
A generator is not a substitute.
A generator covers the outage. Only a UPS covers the transition and the quality of the power itself.
The real question is commercial.
What one hour of downtime costs you, against the cost of protecting the load properly.
Vertiv UPS range
One platform from a single rack to multi-megawatt.
| Model | Capacity | Typical application |
|---|---|---|
| GXT5 | 0.7 – 10 kVA | Racks, edge sites, small IT rooms |
| ITA2 | 10 – 40 kVA | Comms rooms, small facilities |
| EXS | 10 – 80 kVA | Commercial buildings |
| EXM2 | 100 – 250 kVA | Industrial sites, medium data centres |
| Liebert EXL S1 | 300 – 1200 kVA | Large facilities, monolithic platform |
| PowerUPS 9000 | 250 kW – 5 MW | Modular, hot-swap, multi-megawatt |
Scalable.
Single units and paralleled systems, with modular capacity that grows with the site — up to and beyond 9.6 MW in a single installation.
Battery options.
VRLA for lower capital cost, lithium-ion for roughly three times the cycle life.
Kstar partnership.
For the 1 – 30 kVA band we also supply Kstar UPS systems — single-phase and three-phase — with the same survey, installation and maintenance scope.
Large-frame systems
Vertiv Liebert EXL S1Vertiv Liebert EXL S1
The proven monolithic platform
- Transformer-free design
- Up to 97% efficiency in double conversion, up to 99% in Dynamic Online mode
- Smallest footprint in its class, leaving more room for revenue equipment
- Up to eight units in parallel, distributed or centralised
- VRLA or lithium-ion battery systems
Vertiv PowerUPS 9000Vertiv PowerUPS 9000
The newest modular platform
- 125 kW power modules in a 1250 kW single frame
- Up to 97.5% efficiency in double conversion, up to 99% in Dynamic Online mode
- Up to 32% space saving against the previous generation
- Hot-swap power modules and static bypass — no shutdown to service
- VRLA, lithium-ion or nickel-zinc, with skid-mount and containerised options
Both platforms parallel to well beyond 9.6 MW in a single installation, and both are sized from a load survey rather than a nameplate figure.
Batteries
Autonomy, engineered.
We supply and install industrial battery plant from FIAMM and Leoch — VRLA and lithium-ion — engineered for the autonomy your operation requires, and replaced on a planned cycle rather than on failure.
How we work
Load survey
We measure what is actually there, including true power factor.
Sizing and redundancy
We specify N, N+1 or 2N against the operational risk you carry.
Supply and installation
Genuine factory equipment, installed by our own engineers.
Commissioning
Tested and handed over, with documentation.
Maintenance
Preventive contracts, on-call or 24/7 cover, with local spares.
