FAQ

Battery energy storage systems, also known as BESS, are innovative solutions that enable the efficient storage of electricity. These rechargeable batteries have the capability to store excess energy during periods of low demand and release it during peak demand, ensuring a balanced and reliable power supply.

Battery energy storage systems operate using advanced technologies that efficiently store and manage energy. They are equipped with control systems that monitor energy levels, optimize charging and discharging cycles, and ensure a reliable and stable power supply.

Battery Energy Storage Systems can store energy from renewable sources such as solar panels and wind turbines, ensuring a sustainable and environmentally-friendly energy storage solution.the power grid during off-peak hours when electricity demand is low, allowing for efficient utilization of excess energy and reducing strain on the grid.

The storage duration of battery energy storage systems relies on various factors, including the battery technology used, the energy capacity of the system, and the rate of energy discharge. However, they are designed to store energy for sufficient duration to meet the needs of different applications.

The use of Battery Energy Storage Systems can also contribute to a more efficient use of renewable energy sources, such as solar or wind power, by storing excess energy generated and using it when there is a lower supply.

At our factory, we have implemented a robust quality management system that guarantees the excellence of our battery energy storage systems. This system encompasses various quality control measures, such as thorough material inspections, in-process checks, and final product testing, to ensure consistent and reliable performance.
