Configuration
8.1
Configuration Procedure
Once you have commissioned the inverter, you may have to adjust various settings via the rotary
switches in the inverter or via a communication product. This section describes the procedure for
configuration and gives an overview of the steps you must perform in the prescribed order.
Procedure
See
1.
In order to use the Webconnect function, integrate the in-
verter into the network.
Section 8.2, page 36
2.
To manage the PV system data or to set the inverter pa-
rameters, capture the inverter in a communication product.

5.
For partially shaded PV modules and depending on the
given shading situation, you should set the interval at
which the inverter optimizes the MPP of the PV system.

8.2
Integrating the Inverter into the Network
If the router supports DHCP and DHCP is enabled, the inverter will automatically be integrated into
the network. You will not need to carry out network configuration.
If the router does not support DHCP, automatic network configuration will not be possible and you
will need to use SMA Connection Assist to integrate the inverter into the network.
Requirements:
☐ The inverter must be in operation.
☐ There must be a router with Internet connection in the local network of the system.
☐ The inverter must be connected to the router.
Procedure:
• Integrate the inverter into the network by means of the SMA Connection Assist. Download the
SMA Connection Assist and install it on the computer (see www.SMA-Solar.com).
