If only one Sofar 30~40KTL is used, use a communication cable with waterproof RJ45
connectors, and choose either of the two RS485 ports and need to set the SWT4(RS485
address as shown in Figure 4

By the WIFI interface, transfer the inverter power output information, alarm information,
operation state to the PC terminal or local data acquisition device , then uploaded to the
server (such as S-WE01S).
According to the manufacturers to provide SN number can register remote monitoring of

The length of the RS485 communication cable should be less than 1000 m.
The length of the Wifi communication cable should be less than 100 m.
If multiple Sofar 30~40KTL are connected to the monitoring device over an RS485/RS232 converter, a
maximum of 31 inverter can be connected in a daisy chain.
If multiple Sofar 30~40KTL are connected to a S-WE01S, a maximum of 31 Sofar 30~40KTL can be
connected in three daisy chains.
The Sofar 30~40KTL has a multifunctional relay , its output can be configured. The connecting
terminal in a communication board, as shown in Figure4-8. Connecting CNT10 view as shown
as follow.
It can be connected to the normally open mode (i.e. connecting NO contact and COM
contact),can also be configured as a normally closed mode (i.e. connecting NC contact and
COM contact).
The Relay has 4 different control function, the details please see the LCD display interface
