Active power and reserve
The actual load in watts, load peaks and planned expansions determine the system more than the kVA number alone.
Powerful UPS systems for critical loads
UPS systems over 10 kVA are used when individual devices are no longer sufficient and entire server rooms, production areas, controls, building systems or technical systems need to be protected.
ERREPI supports you in selecting and designing suitable UPS systems over 10 kVA. We check the load, power reserve, connection type, battery concept, desired backup time, bypass, installation site, monitoring, commissioning and subsequent service.
For larger UPS systems, it's not just about the right power rating. It is crucial that the UPS, battery, power distribution, environment and operating concept fit together.
For server rooms, industry, building automation, elevators, security technology, production and critical infrastructure.
Project instead of individual device
In small UPS systems, individual loads are often the focus. For systems over 10 kVA, several technical points must be considered together.
The actual load in watts, load peaks and planned expansions determine the system more than the kVA number alone.
Network form, protection, sub-distribution, neutral conductor and protection concept must match the existing supply.
Battery capacity, battery cabinet, weight, temperature and later interchangeability should be taken into account early on in the design.
A larger UPS must be reportable, maintainable, testable and documented in a comprehensible manner during ongoing operation.
ERREPI clarifies the key technical data before power rating, accessories, bypass, installation site and commissioning are determined.

Critical loads

Elevators, machines, pump controls, test benches, security and communication systems as well as project-specific loads.
Fans, door controls, communication, lighting, operator stations, control transformers, sensors or other defined additional loads.
Not just power rating
The decisive factor is the actual active power in watts, including reserves for expansions, load peaks and aging.
Input, output, protection, neutral conductor, network type and existing sub-distribution must match the system.
The desired runtime determines battery size, space requirements, weight, costs and maintenance.
For larger outputs, external battery modules or battery cabinets are often used.
An internal or external service bypass can enable maintenance, testing or replacement in a controlled manner.
Battery operation, malfunction, remaining running time, overload, bypass operation and battery replacement requirement should be reported.
UPS and battery require appropriate space, ventilation, temperature, load capacity, connection space and access.
Heat emission, air flow, dust, temperature and room climate influence operational safety and battery life.
Connection testing, parameterization, functional testing, load testing, battery testing and documentation belong together.
Example structure
The UPS supplies defined loads or load groups. Depending on the project, IT, control, building technology or technical systems are prioritized separately. In addition, battery, bypass, monitoring, power distribution and service access are integrated into the overall concept.
A notice:The illustration shows a principle. Connection, protection, network form, protection concept, bypass, battery, installation site and responsibilities are checked on a project-specific basis.

Replace existing UPSFrom the load to the operational system
We record which loads should be protected and what behavior is expected in the event of a power failure.
We check power rating, load peaks, connection type, protection, network type, sub-distribution and expansions.
We select power rating, design, battery, running time, reserve, bypass, monitoring and accessories.
We consider space, weight, temperature, airflow, connection space, power distribution and service access.
Depending on the project, we provide support with delivery, parameterization, functional testing, documentation and subsequent service.
Operational reliability for years
For larger UPS systems, operation over the entire life cycle is crucial. Batteries, fans, error memory, load level, bypass, interfaces and environment should be checked regularly.
Checking operating status, load, battery, environment, ventilation, error messages, bypass, connections and interfaces.
Selection of suitable batteries, replacement, functional test and orderly disposal.
Analysis of alarms, short runtime, battery errors, overload, bypass operation, switching problems or communication errors.
Check whether the existing UPS still fits the current load and the desired backup time.
Evaluate whether repair, battery replacement, expansion or replacement of the entire system makes more sense.
Documentation of UPS type, battery date, loads, runtime assumptions, messages and follow-up recommendations.
Typical project case
A company operates several critical loads in a server and equipment room. Over the years, various smaller UPS systems have been added. The actual running time is unclear, batteries were replaced at different times and there is no consistent monitoring.
In the first step, the connected loads are recorded and prioritized. Power rating, connection, desired running time, space requirements, battery concept, bypass and service access are then checked.
On this basis, a UPS system over 10 kVA is designed. The most important loads are supplied in a structured manner, messages are passed on to monitoring and the battery replacement is documented in a planned manner.
The previously grown UPS structure will be replaced by a comprehensible, maintainable and documented solution. Power rating, runtime, monitoring, battery and service are clearly defined.

FAQ
This depends on the application, load, connection type, running time, battery, bypass, monitoring and installation site. From 10 kVA the UPS should be designed specifically for the project.
No. kVA describes the apparent power, kW the active power. When selecting a UPS, it is important to know what actual active power is required in watts or kilowatts.
A three-phase UPS can be useful or necessary if the connected load, existing supply, load structure or power distribution require it.
This depends on the load and battery size. The higher the load and the longer the running time, the greater the battery capacity, space requirement, weight and costs.
Yes, depending on the UPS system. External battery modules or battery cabinets are used when longer runtimes or higher reserves are required.
For larger UPS systems, a service bypass often makes sense so that maintenance, testing or replacement can be carried out in a controlled manner.
Yes. To do this, we check the existing power, connection data, batteries, bypass, interfaces, installation situation, load and desired function.
This depends on the battery type, temperature, load and age. It is important to carry out regular inspections and timely planned replacements.
Yes, if space, weight, temperature, air flow, connection space and service access are suitable. Battery, heat output and maintainability must be checked.
Yes, if the load profile, connection, load, protection target and environment are suitable.
Yes. Depending on the project, ERREPI supports delivery, integration, parameterization, functional testing, documentation, maintenance and later battery replacement.
If requirements are clearly defined, a product comparison is possible. We often recommend a technical check before ordering to ensure that power rating, battery, bypass, connection and accessories match the application.
No. A UPS bridges power outages immediately and protects defined loads. An emergency power generator can be useful in the event of longer outages and must be planned separately.
