Configuring Ethernet

1. Goal

Connect your Charge Controller to your Backend through Ethernet or use the Ethernet connection for other communication such as with an energy manager or DLM.

2. Requirements

• You have a local wired network that is connected to the Internet through a router
• Your Charge Controller is connected to your local network

3. Overview

Location in Config UI	Parameter	Description
# BACKEND > Connection	Connection Type	Specifies how the Charge Controller connects to the backend
# NETWORK > LAN	Mode for network configuration	Different configuration modes for integration into the network

4. Configuration

1. In the Config UI, under BACKEND > Connection for Connection Type, choose Ethernet
2. Under NETWORK > LAN set Show LAN Configuration to Show
3. Follow the steps in either section below based on whether your router is operating in DHCP or static mode

4.1. DHCP-based router configuration

If your router assigns the IP addresses automatically, choose Auto (DHCP Client) for Mode for network configuration and configure the following parameters:

4.1.1. Relevant parameters

Location in Config UI	Parameter	Description
# NETWORK > LAN	DHCP client hostname	Hostname string
# NETWORK > LAN	DHCP client request retries	Number of connection attempts
# NETWORK > LAN	DHCP client request timeout	Timeout in seconds
# NETWORK > LAN	DHCP client request delay	timeout in seconds

In general, the default values for the parameters above work and don't need to be changed.

info

Whether the DHCP client hostname field has to filled out, depends on your network. Contact your network administrator.

tip

Have your router give out static IP addresses when using DHCP if this option is available.

4.2. Static IP assignment-based router configuration

1. For the Mode for ethernet configuration, select Manual config
2. Configure the following parameters:

Location in Config UI	Parameter	Description	Example value
# NETWORK > LAN	Static network configuration IP	Static LAN IP address of the Charge Controller	192.168.0.100
# NETWORK > LAN	Static network configuration netmask	Static LAN IP network mask of the Charge Controller	255.255.255.0
# NETWORK > LAN	Static network configuration gateway	IP address of the gateway/router	192.168.0.1
# NETWORK > LAN	Static network configuration DNS		8.8.8.8

With this approach you have to define the network parameters manually. Use each IP address only once within your network to avoid discoverability issues. If unsure, contact your network administrator.
