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 UIParameterDescription
BACKEND > ConnectionConnection Type Specifies how the Charge Controller connects to the backend
NETWORK > LANMode for network configurationDifferent 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 UIParameterDescription
NETWORK > LANDHCP client hostnameHostname string
NETWORK > LANDHCP client request retries Number of connection attempts
NETWORK > LANDHCP client request timeout Timeout in seconds
NETWORK > LANDHCP 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 UIParameterDescriptionExample value
NETWORK > LANStatic network configuration IP Static LAN IP address of the Charge Controller192.168.0.100
NETWORK > LANStatic network configuration netmask Static LAN IP network mask of the Charge Controller255.255.255.0
NETWORK > LANStatic network configuration gateway IP address of the gateway/router192.168.0.1
NETWORK > LANStatic 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.
