figure 5-5 Multi-inverter Connection
When more than 15 inverters are connected to the same daisy chain, in order to ensure the
communication quality, the Logger at the first end of the daisy chain needs to be equipped
with a terminal resistor of 120Ω, the inverter at the last end needs to be equipped with a
RS485-dip switch (SW1), and the shielding layer of the communication cable should be sin-
gle-point grounded.
figure 5-6 Configuration of Dip Switch (N≥15)
The length of the RS485 cable and twisted pair cable should be no longer than
1,200m.
If multiple inverters are connected to the data logger, the number of permissible
daisy chains and the number of devices allowed to be connected should meet the
requirements (refer to the user manual for the data logger).
