Interface（RJ45）】
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 single-point
grounded.
