Sma Shadefix; Sma Smart Connected; Sma Speedwire; Surge Arrester Type 1+2 Or Type 2 - SMA Sunny Tripower X 12 Operating Manual

SMA Solar Technology AG 4 Product Overview

4.5.12 SMA ShadeFix

The inverter is equipped with the shade management system SMA ShadeFix. SMA ShadeFix uses
an intelligent MPP tracking system to determine the operating point with the highest output during
shading conditions. With SMA ShadeFix, inverters use the best possible energy supply from the PV
modules at all times to increase yields in shaded systems.
SMA ShadeFix is enabled by default.
The time interval of SMA ShadeFix is usually 6 minutes. This means that the inverter determines the
optimum operating point every 6 minutes. Depending on the PV system or shading situation, it may
be useful to adjust the time interval.

systems.
The products supports the encrypted system communication with SMA Speedwire Encrypted
Communication. In order to be able to use the Speedwire encryption in the system, all Speedwire
devices, except for the energy meter (e.g. SMA Energy Meter) must support the function
SMA Speedwire Encrypted Communication.

4.5.15 Surge arrester type 1+2 or type 2

The inverter has a DIN rail that serves as a mounting location for the DC overvoltage protection.
The DC overvoltage protection with surge protection devices of the type 1+2 or type 2 is available
as an accessory. The surge protection devices limit dangerous overvoltages.

4.5.16 Wi-Fi

The product is equipped with a Wi-Fi interface as standard. The inverter is delivered with the WLAN
interface activated as standard. If you do not want to use WLAN, you can deactivate the WLAN
interface.
In addition, the product has a WPS function. The WPS function is for automatically connecting the
