The ideal solution for an uninterruptible power supply (UPS) with Commeo
In private households, a short-term power failure that is rectified within a few seconds usually causes no further problems. However, the situation is different in companies and institutions. They often contain sensitive systems and machines that react sensitively to power failures. Even the smallest power fluctuations can be problematic for these devices. In addition to a complete power failure, even overvoltage or undervoltage as well as frequency deviations or harmonics can cause damage.
In particular, computers and servers in data centres, medical devices, sensitive measuring instruments, telecommunications systems, wind turbines, security equipment and critical infrastructure must be continuously supplied with power and protected against failures.
The ideal solution for such scenarios is an uninterruptible power supply (UPS). It ensures that the devices continue to run immediately and reliably even in the event of power failures. How the UPS works in conjunction with Commeo’s intelligent energy storage solutions is explained in the following article.
The difference to backup or emergency power supply
The uninterruptible power supply (UPS) is a form of backup or emergency power supply. In both backup power and emergency power supplies, the power is drawn from a battery storage system and replaces the power from the public grid or another regular power source.
However, both variants are associated with longer switching times or even manual switching. With the backup power supply, switching is usually automatic, but in practice it often takes one to five seconds. However, this seemingly short period of time can lead to malfunctions with sensitive current collectors.
Emergency power must sometimes be activated manually and normally only applies to predetermined consumers in a single-phase circuit, not to the entire operation. These backup solutions are therefore only suitable for applications in which a short-term failure does not cause serious problems. A temporary failure of the lighting, for example, does not usually cause any problems. Sensitive machines, on the other hand, can only cope with short power interruptions with difficulty, which is why special precautions must be taken in the event of a power failure.
What is the technology behind the uninterruptible power supply?
From a technical point of view, the uninterruptible power supply (UPS) mainly consists of three components: a battery storage system that supplies the backup power, a high-quality inverter and the advanced Energy Control System. With its powerSecure product, Commeo offers an intelligent combination of these components to guarantee a continuous power supply.
As soon as the system registers that the power from the public grid is failing, the battery storage system takes over the power supply within milliseconds. This time span is so short that even sensitive devices do not notice the failure and continue to function perfectly. In this way, the entire system is protected from the consequences of voltage drops or frequency fluctuations.
The battery storage system for an uninterruptible power supply
For an uninterruptible power supply to be successful at all times, it is crucial that the battery storage system is sufficiently large and configured to fit perfectly. This solution only makes sense if the size of the storage system can supply the consumers with sufficient power until the normal grid is available again.
When dimensioning the solution, it is important to quantify the failure risks and dimension the storage system accordingly. Commeo offers you various solutions to ensure the security of your energy supply at all times. These range from small, modular energy storage blocks (esbL) to large battery storage systems in container format. What all storage systems have in common is that they are based on modern NMC technology (lithium-nickel-manganese-cobalt-oxide), which is also used in the batteries of electric cars. These batteries combine high energy density with high cycle stability. Up to 10,000 charge and discharge cycles are no longer a problem for modern high-performance storage systems. High capacity and a long service life are the ideal combination for a future-proof and sustainable energy supply when it counts.
Commeo systems are perfect for ensuring an uninterruptible power supply (UPS). For example, they can buffer high start-up currents when starting systems or compensate for reactive power. The Commeo Edge UPS offers particularly long bridging times. With just 6.6 kWh, 20 kW of power can be provided for up to ten minutes. Both single-phase and three-phase supply is possible. The system can be individually configured and realised in the smallest of spaces.
