SMA ShadeFix – intelligent energy optimization
Established product features and integrated software solutions will ensure yield optimization throughout the life of the system. This is true even in the shadows. SMA ShadeFix is ​​a patented inverter software that optimizes energy output in almost any situation. SMA Smart Connected inverter monitoring provides added safety by detecting errors at an early stage and automatically reporting them to the installer.

SMA ArcFix – effective prevention of electric arcs
An Arc Fault Interrupter (AFCI) effectively detects possible electrical arcs in a PV system and the inverter stops supplying power before a fire can occur. SMA was one of the pioneers in introducing AFCI in the United States and has continually improved the solution over the past decade. In the future, we will equip all of our string inverters worldwide with our AFCI SMA ArcFix solution. In this way, we will consistently improve the already high safety standards of photovoltaic systems.

SMA Smart Connected – proactive communication in case of failures
SMA Smart Connected allows you to monitor your inverter for free through the SMA Sunny portal. If If the inverter fails, SMA will inform the system operator and installer in advance. This saves valuable working time and costs.

With SMA Smart Connected, the installer benefits from fast diagnostics using SMA. This allows the installer to quickly fix the problem and offer customers a number of additional and very attractive services.
