Discover the new BESS energy storage technology that promises to put an end to off-grid systems, bringing more safety and reliability.
The recent blackouts in São Paulo left the city in the dark for days and the impact was so devastating that it caused an incredible 1.65 billion in losses for the retail and service sectors, highlighting the fragility of our electrical infrastructure. However, this situation could have been different if businesses and industries had access to more robust clean energy storage systems in their operations. Therefore, in this article we will present the BESS energy storage system, which outperforms off-grid systems.
Main difference of this type of clean energy storage
First we need to understand the meaning of BESS, an acronym that comes from English and freely translated means battery energy storage system.
This energy storage differs from traditional off-grid systems in its ability to serve large loads such as commercial and industrial needs, overcoming significant technical challenges.

In off-grid systems, problems such as battery imbalance and overheating can compromise efficiency and even more safety, making maintenance more expensive and much more complex. With BESS, these limitations are overcome and batteries are central components of the systems, where energy is stored.
Lithium-ion batteries are generally used for this type of system. To maintain the functioning of the component, there is also the BMS, the battery management system that monitors, manages and protects the performance of the batteries, ensuring safety and efficiency in their operation.
In this way, the BMS will ensure that the battery cells are charged and discharged in a balanced manner, in addition to monitoring the temperature, voltage, current and the overall health of the system to prevent overcharging or damage. All of this will maximize the lifespan of the batteries. Batteries.
Other BESS equipment that outperforms off-grid systems
Another component that makes the clean energy storage system stand out is the PCS, which stands for energy conversion system and is like an inverter for storage that outperforms off-grid systems. It converts energy from direct current to alternating current or from alternating current to direct current, it all depends on the application.
Finally, we have the EMS, which is the energy management system. It is the brain of the entire system, being able to control the use of stored clean energy, defining when to charge or discharge the batteries according to demand, the availability of energy sources and the conditions of the electrical grid.
This equipment coordinates the work between the different BMS, PCS and other auxiliary components of the energy storage system. Looking at the general composition of the BESS, we will still have other equipment such as transformers, protection panels, monitoring systems and others.
Main applications of clean energy storage system
What really stands out is the number of applications that BESS provides. The first is power backup, which could solve the problems faced by consumers in the city of São Paulo in critical facilities such as hospitals, data centers, industries and even supermarkets.
The BESS can act as a backup power source, ensuring supply in the event of a power grid failure. The interesting thing is that, unlike a traditional generator, the BESS kicks into action quickly, providing instant power to keep essential equipment running without interruptions, which is a big advantage.
Another application would be integration with clean energy sources such as solar and wind. BESS can act as a solution to store excess energy generated during periods of high production and solve the problem of intermittency, since the sun does not shine all the time and the winds do not blow 24 hours a day.
