But when you''re drawing current, the regulator has to deliver longer lasting pulses of current to replace the lost charge. It turns out that narrow pulses have more high frequency energy than longer pulses, and promote buzzing more. The buzzing itself is a mechanical motion due to the pulsed magnetic field.
The use of battery storage helps the grid to remain stable due to its ability to respond quickly to changes in energy demand. Grid-scale battery storage has the potential to significantly assist in the renewable energy transition. Noise has emerged as a key environmental impact challenge in the development of BESS. But why?
Where Does the Noise Come From? Solar batteries do not have any moving parts. So, they do not produce much noise compared to generators and other power backup systems. The only sound you may hear is a faint buzzing or humming noise from the solar inverter. This device is used to convert the DC energy from the battery into AC energy.
