7.5 Network and Internet

7.5.1 Accessing Inverter via LAN (Local Area Network)

The illustration above is a typical LAN connection. The inverter and devices are
connected to a router by Ethernet cable or Wi-Fi. Computers and other devices
in the LAN can access inverter’s data if its IP address is known.

The router, acting as a DHCP server, usually assigns an IP to the inverter
automatically. You can also manually assign an IP to the inverter with the router
as well. Use touch pad to go to “Operation Frame” for IP confirmation.

7.5.2 Accessing Inverter via Internet

The illustration above demonstrates how to access the inverter via Internet.
Similar to LAN, the inverter can be accessed by web browser. However, there is
usually a firewall that would block direct access of the LAN from the Internet. In
order to overcome this, you will need to set up NAT (Network Address
Translation) or Port Forwarding of the router. For detailed information, please
refer to the manual provided by your router supplier.
