7.1.10 Internet based remote access to the inverter
There are three feasible scenarios for remote access to the inverter from the internet. The configuration is explained in the
following chapters with the example of the widely used FRITZ!Box router from AVM. Routers from other manufacturers will
not support remote access with the MyFritz! account. If remote VPN connections are available will be detailed in their
corresponding manuals.
1. Remote access via port forwarding with DynDNS (chapter 7.1.10.1)
2. Remote access via port forwarding with a MyFRITZ! account (chapter 7.1.10.2)
3. Remote access via VPN using DynDNS or a MyFRITZ! account (chapter 7.1.10.3)
Strictly speaking, there are only two different scenarios: remote access via port forwarding or VPN. The
MyFRITZ! account ensures, just like DynDNS, the name resolution for access to a private internet connection. These are
usually set up with a dynamic IP address resolution by the internet service provider.
For a corporate internet
connection with a static IP, a MyFRITZ!account or DynDNS are not required. The remote access is established via the known
fixed IP address.
There are pros and cons to both methods. Port forwarding is easier to configure. The inverter can be accessed directly from
the Internet and poses a potential security risk. Access via VPN (Virtual Private Network) is generally more secure. The
connection from a mobile device to the inverter network is encrypted. The configuration of the VPN can, however, be more
complex than port forwarding.
7.1.10.1
Remote access via a FRITZ!Box with port forwarding and DynDNS
Remote Access to devices connected to a home network using an internet connection always poses a potential security risk.
It requires changes to your network router settings. You may need to contact your internet service provider to have some of
the required settings options enabled.
To enable remote access over the Internet, the inverter must be connected via Wi-Fi or LAN to a stable home network with
access to the Internet.
One of the following conditions must be met:
•
The router supports port forwarding and connects to the internet using a fixed IP address assigned by the Internet
Service Provider.
This is usually only a common set up for corporate internet connections.
If this condition is met continue to 7).
•
The router supports port forwarding and connects to the Internet using a dynamic IP address assigned by the
Internet Service Provider. Dynamic Domain Name System entries are enabled.
This is usually a common set up for most private Internet connections.
The following section describes how to set up the remote access via DynDNS using a Fritz!Box router. If you are using a router
from a different manufacturer, these instructions may differ.
The latest Fritz!OS firmware is Version 07.20. Older firmware might have different configuration menus and Interface layout.
FRITZ!Box is a brand of AVM Computersysteme Vertriebs GmbH
