8 Communication and monitoring
8.1 Communication interface
This product has a standard communication interface RS485 and RS232. Operating
information like output voltage, current, frequency, fault information, etc., can be
delivered to PC or other monitoring equipment via RS485 and RS232.
8.2 Communication
When the user wants to know the information of the power station and manage the entire power system,
we oer below two types of communications.
1 RS-232 Communication
RS-232 is one standard communication interface. It transmits the data between PC and
one single Enfinity inverter (figure 27).
