Comprehensive testing points the way to significantly reducing noise from central inverters
Reducing Noise in PV Power Plants
Typically, PV power plants are spread out over several acres of land far from residences, towns or cities. Up until now, central inverter manufacturers have not had to deal with noise emissions from the central inverters in and near such large industrial PV farms. In collaboration with the Rheinisch-Westfälischen Technischen Hochschule Aachen (RWTH University Aachen), SMA Solar Technology AG carried out comprehensive and complex testing to identify the sources of noise and ways to reduce it. We found that because noise emissions behave logarithmically, a 10dB reduction will cut the central inverter’s noise emissions by half.
