Disassembly the inverter from the Grid:
5) The cables are inserted into the terminal accord-
ing to the wire sequence (L1/L2/L3/N/PE), so that
the insulating terminal is flush with the surface of the
terminal, and the crimping screw torque is
2.0±0.1N•m.
6) Insert the main part of AC connector into the
terminal and hear a "click" sound.

1) Use a screwdriver to press against the unlocked
position and hold the wire nut and pull it back to
complete the separation of the male and female
ends.

3.5.3 Communication
Overview of communication ports:
3.5.3.1 WIFI/GPRS Communication (optional)
Connect the WIFI/GPRS module produced by Rayleigh Instruments to the COM1 port of inverter. After successful connection,
information such as power generation and running state of the inverter can be viewed via the App on the phone. For details
please refer to the module user manual. The block diagram of the WIFI/GPRS communication system is as follows:
3.5.3.2 Smart Energy Meter Connection (Optional)
The inverter is equipped with the feed-in power limit function, and the communication port for smart energy meter is COM2,
below is the method of connecting the smart meter in system.
3.5.3.3 DRM connection
The inverter supports the demand response modes as specified in the standard AS/NZS4777. The inverter has integrated a
terminal for connecting to a DRED. The details please refer to figure 3-17, and for CEI standard, DRM S0 is the DI port .
3.5.3.4 Relay connection
The relay can be set to fault alarm output, and user can configure it to be a normal open contact (COM＆NO) or a normal
close contact (COM＆NC).The relay is initially at the NC terminal, and it will trip to another contact when a fault occurs.
Use LED indicators or other equipment to indicate whether the inverter is in the faulty state. The following figures show
the typical applications of normal open contact and normal close contact:
COM2
CGNCGN
CGNCGN
Free of fault, relay does not
trip. Circuit is disconnected,
and LED indicator is off.
Fault occurs, relay trips.
Circuit is connected, and
LED indicator gets on.
Free of fault, relay does not
trip. Circuit is connected, and
LED indicator is steady on.
Fault occurs, and relay trips.
Circuit is disconnected and
LED indicator gets off.

Before turning on the inverter, please confirm the following:-
1 ) The three-phase (five wires - PE/L1/L2/L3/N) cable is correctly connected to the inverter AC side through an AC
circuit breaker;
2) The DC cable is correctly connected to the inverter DC side through a DC circuit breaker. Ensure the correct
connection of the two strings and their polarity.
3) Any unused terminals are covered.
1 ) Close the DC and AC circuit breakers;
2) If the solar panels are providing enough energy, the power module will function and the LCD panel will be lit;
3) If you are starting the inverter for the first time, the inverter needs to be commissioned. The process of
commissioning is described on page 17, chapter 4.3.
4) The inverter will then enter self-check mode and the LCD panel will simultaneously display the remaining time
of connection.
5) The inverter should then enter normal operations mode and will feed electrical energy into the grid, and the LCD
panel will display the generated electrical energy.
