5.3 Configuring the IP Address of the Inverter for Static Networks
The inverter has 3 LAN interfaces for connecting nodes.
• The inverter-internal network is available via LAN1. The network settings for this interface are preset and cannot be
changed. The default IP address of the LAN1 interface is 192.168.100.2.
• The control network is available via LAN2. Here the SC-COM receives the setpoint specifications of the grid operator
and forwards these specifications to the inverter. The default IP address of the LAN2 interface is 10.112.4.1.
• The monitoring network is available via LAN3. The inverter sends data via this interface to Sunny Portal or the OPC
client, for example, for visualization and analysis purposes. The default IP address of the LAN3 interface is
10.111.1.1.
Procedure:
1. Log in to the user interface.
2. Select Sunny Central > Settings > Network.
3. In the IP address field, enter the static IP address that you want to use to access the inverter in the local network.
4. Enter the subnet mask of your network in the Subnet mask field.
5. Enter the gateway IP address of your network in the Gateway address field. Usually, the IP address of the router
has to be entered here.
6. Enter the IP address of the DNS server (Domain Name System) in the DNS server address field. Usually, the IP
address of the router has to be entered here.
7. Select [Save] and [Confirm].
5.4 Configuring the IP Address of the Inverter for Dynamic Networks
The inverter can obtain the network settings from a DHCP server. The IP address, subnet mask, gateway and
DNS server are automatically obtained from the DHCP server during startup of the inverter.
Procedure:
1. Log in to the user interface.
2. Select Sunny Central > Settings > Network.
3. Activate DHCP in the IP address field.
4. Select [Save].
Use of DHCP
Before setting the inverter to dynamic IP address assignment, check your DHCP server. The DHCP server must extend
the lease of the assigned IP address. Do not use the DHCP server if it assigns a new IP address after the lease has
expired. DHCP servers can normally list all devices to which you have assigned an IP address. You can now identify
the inverter via its MAC address. The MAC address of your inverter can be found on the type label or by selecting
Sunny Central > Info in the user interface.
