Manual of 07/06/2019 Rev. 2.1 “User Manual for 3K-6KTLM LITE 

Note: 

It is recommended to use two different wire colours to connect TX- (485-) and TX+ (485+). Wires of 

the same colour can be connected together to avoid incorrect wire connections.

Communication systems

 

The 3-6K TL inverters are equipped with RS485 (standard) and Wi-Fi (optional) communication systems. 
These  communication  systems  allow  monitoring  the  main  parameters  of  the  inverter  (energy  generated, 

alarms, operating status) through various channels, such as the ZCS AZZURRO portal, ZCS AZZURRO app or 
your own monitoring system. 

RS485 

For a single inverter it is possible to connect the RS485 port to a terminal such as a PC, using a special RS485 / USB 
converter. In this way, it is possible to create a personal system for data acquisition and monitoring of the inverter, 
upon request of the Modbus RTU proprietary protocol to ZCS S.p.A. 

Alternatively, the RS485 port can be connected to an external datalogger, which is not supplied with the inverter. 
In turn, this datalogger can be connected to a router or a modem via Wi-Fi or ethernet cable to allow data to be 
sent to the ZCS server.   

 

Figure 37 – Connecting an inverter with RS485

 

For a group of inverters, it is possible to connect up to 31 inverters in a daisy chain via the RS485 port. The 

first in this series must then be connected to a terminal in the manner described above.
