Vertiv Liebert-EXS

The Vertiv EXC is a modern, fixed-capacity UPS platform designed for commercial and light-critical applications where load is well defined and reliability and serviceability are priorities.

Unlike fully scalable modular UPS systems, the EXC uses serviceable power modules to reduce downtime during maintenance and repairs, while system capacity is defined at installation.

We support the full lifecycle of Vertiv EXC systems — from supply and installation through to battery replacement, maintenance, and fault response.

Vertiv EXC UPS Supply

We supply Vertiv EXC UPS systems for:

• New installations

• Replacement of ageing UPS platforms

• Projects where modular growth is not required

System selection is based on:

• Connected and future load assessment

• Required autonomy (runtime)

• Site layout and electrical constraints

• Battery technology selection

Because EXC capacity is fixed, correct sizing at the start is critical. We focus on right-sizing, not overselling.

Installation & Commissioning

Installation and commissioning are carried out to ensure the system operates as designed from day one.

Scope includes:

• Mechanical installation and positioning

• AC input, output, and bypass connections

• Battery system installation and integration

• System configuration and parameter setup

• Functional testing and handover

Commissioning ensures:

• Stable operation under load

• Correct transfer between operating modes

• Verified alarm and monitoring behaviour

Battery Replacement & Battery Support

Although the Vertiv EXC is a relatively new platform, battery systems remain a consumable component and will require attention over time.

We support:

• VRLA battery replacement

• Battery inspections and testing

• Runtime verification

• Preparation for planned battery change-outs

Battery work is carried out with:

• Minimal disruption to site operations

• Clear understanding of bypass and protection requirements

• Correct handling and disposal procedures

Preventative Maintenance & Fault Response

Regular maintenance is essential to maintain reliability and availability.

Maintenance services include:

• Visual and mechanical inspections

• Power module checks

• Cooling and fan inspections

• Control and alarm verification

• Early identification of wear or degradation

For operational sites, we also provide:

• Fault investigation

• Corrective maintenance

• Support for existing Vertiv EXC installations not originally supplied by us

Why Work With Us on Vertiv EXC Systems

• Practical experience with modern UPS platforms

• Clear understanding of EXC design limitations and strengths

• Honest advice on suitability and lifecycle expectations

• Focus on long-term operability, not just installation

This matters particularly with newer UPS platforms, where real-world support capability is often more important than brochure specifications.

Service Coverage

• KwaZulu-Natal (KZN)

• Nationwide support for projects and multi-site customers
