Because conversion is not entirely without noise, please be careful about where you install the system.
Unfortunately, the conversion of direct current into alternating current cannot be performed without any noise. Therefore, we recommend not installing the inverters directly in the living area, but rather in a protected area outdoors, a garage, or in a suitable cellar space.
Further information on the installation site requirements can be found in the installation manual that is included with every inverter. Alternatively, the manuals are also available on the SMA website under ‘Service’, in the download area for the relevant inverter.
As a rule, the relevant values of all our inverters comply with or are even below the permissible limiting values for noise emissions.
Furthermore, when the inverter is not feeding in power to the power distribution grid, it switches off automatically and disconnects all poles from the power distribution grid. In this status, the inverter does not make any noise.
