In systems with Solar Inverters from the PT series
the CAN bridge can be integrated directly in the PT
Solar Inverter and supplied via the 24 V DC power
supply unit of the inverter. In systems with AT Solar
Inverters and units from the new NT series (900 V)
the CAN bridge can be integrated in the AC distri-
bution. In this case an external 24 V DC supply is
required (power consumption 1.5 W).
Networking Solar Inverters via RS485 interface
For joint monitoring of a solar system with Sunways
Solar Inverters from the older NT generation (750 V
or 850 V) you can use the RS485 interface integrated
in the Solar Inverters. The system networked with
the RS485 interface can be monitored with the Sun-
ways Communicator.
· Use a twisted two-wire cable to network the
Solar Inverters with each other.
· Mount the terminating resistor on the last Solar
Inverter.
