The inverter may make noises when in use which may be perceived as a nuisance in living areas. The noises may vary depending on the power and installation site, and other loads can influence noise generation.
In living areas, we do not recommend installing an inverter on gypsum plasterboard or other similar surfaces, in order to prevent the occurrence of audible vibrations.
As long as the inverter does not show an error message, it is assumed that the device is working properly.
In the event of very loud or unusual noises, observe when these occur, if there are any regularities to the noises, whether several or all devices are involved or just some, and contact the SMA Service Line for further consultation.
An inverter specialist will work with you to provide a precise explanation and subsequent steps to remedy the problem as quickly as possible.
