4.13 Setting up the Communication
4.13.1RS485 Network
✅ Assign a unique RS485 ID for each inverter in the
chain using REFUset app between 1 and 31.
Factory default ID is 0.
4.13.2Ethernet Network
✅ DHCP is activated by default, so each inverter will
receive the configuration automatically from the
switch or gateway.
✅ If you change the mode to manual, you have to
assign an unique IP address, net mask, standard
gateway and optionally the DNS server during the
REFUset commissioning wizard.
✅ Before changed network settings become active,
you need to restart the inverter.
1. To restart the inverter, set the DC switch to the OFF
position.
2. Wait for 60 s and then shift the DC switch to the ON
position.
