6.7 Remote access via a DSL router
If a DSL connection or a network with Internet
access is available you can make the Solar Inverter
accessible via the Internet.
Requirement:
Your DSL modem or Internet router supports static
IP address services, e.g. www.dyndns.org
Your router supports port forwarding.
1. Connect your Solar Inverter with your DSL router.
Use a CAT5 Ethernet cable with 1:1 RJ45 sockets.
The master is connected to the network as
standard.
2. Register free of charge at www.dyndns.org, for
example
3. Create an alias for accessing your Solar Inverter,
e.g. nt-sunways.dyndns.org. You can then access
your Solar Inverter via this address.
4. Configure your DSL router such that the IP
address is regularly reported to www.dyndns.org
(follow the procedure described in the manual
for your DSL router for this purpose).
5. Configure your DSL router such that it accepts
requests from the Internet via Port 80, for exam-
ple, and forwards them internally to the Solar
Inverter (port forwarding).
6. Also note that the port for access from the Inter-
net set in your firewall must be enabled.
Instructions for configuring common DSL routers
are available for download from the Sunways AG
website.
