Wels, January 13th 2011
Fronius International GmbH
The inverters Fronius IG Plus 35 – 150 generate the following max. sound power level (ref. 1pW) while
full-load operation according to IEC 62109-1, measured under the terms of ÖNORM EN ISO 9614-2:
Type of inverter Noise Emission Value dB(A), ref. 1pW
Fronius IG Plus 35-1 62,1 dB(A)
Fronius IG Plus 50-1 62,1 dB(A)
Fronius IG Plus 70-1 62,3 dB(A)
Fronius IG Plus 70-2 62,3 dB(A)
Fronius IG Plus 100-1 62,3 dB(A)
Fronius IG Plus 100-2 62,3 dB(A)
Fronius IG Plus 120-3 63,9 dB(A)
Fronius IG Plus 150-3 63,9 dB(A)
The cooling system of the inverter is done by an electronic temperature regulation as quiet as possible
depending on the power, the ambient temperature and the contamination of the device.
A value for the noise emission at the place of installation can’t be given for this device, as the actual
noise level strongly depends on the installation situation on-site, the grid quality, the ambient walls and
the general characteristics of the room.
