Optimize the installation
•
Check whether the interference from troubling devices can be sufficiently
reduced by simply connecting them to another circuit and/or phase.
•
Installing a spur line from the Sunny Boy Control to the inverter(s) can help
reduce the need for costly filters in installations suffering from heavy noise.
Filter the noise
•
Provide the section of the electric installation that is used for Powerline
communication with a wave trap.
•
Connect a suitable filter to devices that are still interfering (refer to section
11.1 Accessories”).
Reduce external interference by installing a frequency damper in a section of the
electric installation where no Powerline communication takes place.
Systematically following the above procedure will give you a clear overview of the
number and types of noise sources interfering with your transmission.
Add-on components such as wave traps, phase couplers, filters, and
dampers are commercially available products. You can purchase them
either from electrical suppliers or from SMA. Their installation takes
place in your home and must be performed by a qualified electrician.
