Networking Solar Inverters via
CAN bus
Solar Inverters from the NT, AT und PT series can be networked via the CAN bus
interface. Use the included Ethernet cable to network the Solar Inverters with
each other. Connect a terminating resistor at the first and last Solar Inverter in
the series. The pluggable terminating resistors are included in the delivery.
1 Terminating resistor connector
The total length of the CAN bus depends on the selected bit rate. The following
table shows the possible bit rates and the resulting bus lengths.
Solar Inverters of the PT series are delivered with a default setting of 125 kbit/s.
The default setting for Solar Inverters of the NT and AT series is 500 kbit/s.
