Image: Wartsila. The noise of battery energy storage system (BESS) technology has “exploded” as a concern in the last six months, an executive from system integrator Wartsila ES&O said. BESS units primarily emit noise from their cooling systems, but balance of system (BOS) components like inverters and transformers also produce noise emissions.
The main noise sources from a BESS facility are: Like any electronic device, grid-scale battery systems operate most optimally and safely at an ideal temperature and humidity. Therefore, various air or liquid cooling and heating systems are used.
Inverter and BESS firm Sungrow pointed out to Energy-Storage.news in a recent interview that its latest generation product increased the energy-per-container from 2.5MWh to 5MWh but the max noise emissions went from 79dB to 75dB. Energy-Storage.news' publisher Solar Media will host the 2nd Energy Storage Summit Asia, 9-10 July 2024 in Singapore.
The core and coil noise are caused by electromagnetic forces which occur two times for every cycle of AC power. Like the inverters, this results in a 120-hertz primary sound source, along with its harmonics. The third source of sound is from cooling fans mounted outside the transformer.
