SMA Solar Technology AG 4 Product Description
The inverter can be equipped with an SMA communication interface (e.g. RS485). This
communication interface will enable the inverter to communicate with special SMA communication
products or other inverters (for information on supported products, see www.SMA-Solar.com). The
interface can either be retrofitted, installed at the factory according to a specific order, or included in
the regular scope of delivery.
You can only set the operating parameters of the inverter via SMA communication products.
Depending on the type of communication, RS485 or Bluetooth, the parameters and messages are
displayed differently on the communication products.
Example: How the country data set parameter is displayed
For communication via RS485: parameter CntrySet
For communication with Bluetooth: parameter Set country standard
This manual specifies the parameter names and messages of the two types of communication.
In the inverter display, the parameters and messages are depicted independently of the connected
communication interface and may also differ.
The inverter is equipped with grid management functions.

Depending on the requirements of the network operator, you can activate and configure the functions
(e.g. provision of reactive power, active power limitation) via operating parameters (for information
on the functions and operating parameters, see the Technical Description "Operating Parameters" at
www.SMA-Solar.com).
The inverter is equipped with five fuse holders for string fuses. String fuses allow the inverter to protect
the PV modules against possible reverse currents.
Whether you have to install string fuses in the inverter depends on the reverse-current resistance of the
PV modules used and the number of strings directly connected to the inverter (for information on the
string fuses, see the Technical Information "Use of String Fuses" at www.SMA-Solar.com).
Use only the string fuses available from SMA Solar Technology AG (see section 13 "Accessories",
page 91).
Note that the string fuses are a precautionary measure only to minimise the risk of fire in the event of
an error, for example. Using string fuses does not guarantee that the PV array is protected against
consequential damage.
