maximum daisy chain length is 1000m.
With multiple daisy-chained inverters, each unit will be automatically assigned a RS485
address with JFY monitoring software.
The RJ45 socket with120Ω terminal resistor should be installed at the last inverter in the
chain. JFY-tech provide a special RJ45 socket with terminal resistor and a vacant RJ45
socket in the attached accessories. When the inverter is not the last one in the chain,
please draw out the terminal resistor and use it as a vacant RJ45 socket.
In order to ensure that the communication on the RS485 line is very safe, JFY-tech
recommends connecting an isolating RS232-485 adapter between the first inverter in the
daisy chain system and the computer. Of course, non-isolating RS232-485 adapter can
also work.
The following diagram shows how to connect multiple inverters in a daisy chain
configuration.

NOTE: The RS485 link supports up to 31 inverters.
NOTE: The RJ45 socket with120Ω terminal resistor should be installed at the last
inverter in the chain. Even if there is only one inverter, the 120Ω terminal resistor is
also necessary.
