SMA Webconnect Data Module

In order to communicate with special SMA communication products or other inverters, the inverter is
equipped with the SMA Webconnect Data Module as standard. With the SMA Webconnect Data
Module you can use the Webconnect function and register your system in Sunny Portal.
The Sunny Portal will then be able to query the current data of your inverter (for information on
capturing your systems in Sunny Portal, refer to the user manual of the Sunny Portal at
www.SMA-Solar.com).
Class 1 wiring methods are to be used for field wiring connection to the terminals of the
SMA Webconnect Data Module.

485 Data Module

The inverter can be retrofitted with a 485 Data Module. The 485 Data Module enables the setup of
cable-connected RS485 communication for SMA inverters (refer to the installation manual of the
485 Data Module at www.SMA-Solar.com).
Class 1 wiring methods are to be used for field wiring connection to the terminals of the
485 Data Module.

Arc-Fault Circuit Interrupter (AFCI)

In accordance with the National Electrical Code
recognition of electric arc detection and interruption.
An electric arc with a power of 300 W or greater must be interrupted by the AFCI in the time
specified by UL 1699B. A tripped AFCI can only be reset manually. The 2011 edition of the
National Electrical Code
building must be fitted with a means of detecting and disconnecting serial electric arcs on the DC side.
If you prefer not to have that function, you can deactivate the arc-fault circuit interrupter via a
communication product (see section 8.4 "Changing Operating Parameters", page 42).
