The newly developed SMA Sunny Boy 4.0 inverter enables faster installation and simple commissioning thanks to the new web interface. Connection to the Internet is via Wi-Fi or Ethernet connection. This newly developed web-based interface enables configuration with a smartphone or in the classic way on a laptop. The 70 percent regulation or even the 0 percent regulation required in Germany is ensured with the installation of the SMA Energy Meter or SMA Home Manager 2.0 through direct communication.
