WI FI wireless communication is functioning within 400m
in an opening distance, but interference and barrier shall
be put into consideration because the actual transmission
distance is influenced by the installation field and external
interference.
The DC side of inverter has 4 terminals totally, including two DC positive
wiring terminals and two DC negative wiring terminals. S ee the figure below:
The two pairs of A/B RS 485 communication wiring terminals at
the inverter communication side are equivalent.
●S ingle-device communication: Either pair of A/B RS 485
communication wiring terminals can be connected if RS 485
module is connected.
●M ulti-device communication: Either pair of the A/B RS 485
communication wiring terminals can be connected to the WI FI
module and the other pair to RS 485 if WI FI module and RS 485
are both connected.
●M ulti-device communication: Two routes of RS 485 can be
connected, and either pair of A/B RS 485 communication wiring
terminals can be used as the input and the other pair as the
output.
