Notice:
1.Under any circumstance, the total current of all strings cannot exceed the inverter's
maximum current
2. Do not touch any working solar panels.
3. Make sure the cable is unbroken.

15> Cable specifications:
RS485 can carry out single-machine communication or multi-machine (32pcs) long-
distance (500 meters) high-speed (baud rate 38400) communication. It is recommended
to use twisted-pair shielded wire for RS485 communication line. For single-machine
communication, the communication line can be connected to pin 3/4, and its shielding
layer can be connected to pin 1. When multiple machines are connected in parallel, two
RS485-1 ports can be connected at the same time. When used, the shielding layer can be
connected to pin 1/2.In Figure 6.6, RS485 has two terminal types, terminal type 1 and
terminal type 2.

Notice:
1.When multiple inverters communicate in parallel, the last machine needs to add
matching resistance. The method is to use a wire to connect the pin 15/16 together.
2.Terminal type 1 and terminal type 2 randomly match the whole machine shipment. The
performance of the two terminals is consistent, only different in appearance. The client
needs to match the corresponding shape terminal to use.

12>For the unused PV terminls on the inverter, please cover them with blue dustproof
caps.
13>When wiring the DC input cables at the installation site, leave at least 50 mm of them
slack. The axial tension on the PV connector should not exceed 80N and do not apply
radial stress or torque on the PV connectors.
14> Connect the positive and negative poles to inverter terminals, different inverter's
maximum single string input current please refer to following table:
