D. Connecting the meter to the Storage/Hybrid Inverter
1. The Growatt Storage Inverter and the Hybrid Inverter are hereinafter collectively referred to as “the Storage/Hybrid Inverter”.
2. The grid is on the right side and the current flows from P1 to P2 (from the grid to the load).
Note:
A. Voltage sampling and power supply wiring
Wiring of the L1 voltage sampling line: corresponding to meter Pin 2;
Wiring of the L2 voltage sampling line: corresponding to meter Pin 5;
Wiring of the L3 voltage sampling line: corresponding to meter Pin 8;
Wiring of the N voltage sampling line: corresponding to meter Pin 10.
B. Current transformer wiring
Please refer to the diagram above. The grid is on the right and the
current flows from P1 to P2 (from the grid to the load).
Wiring of the L1 CT: S1 Line corresponding to meter Pin 1, S2 Line
corresponding to meter Pin 3;
Wiring of the L2 CT: S1 Line corresponding to meter Pin 4, S2 Line
corresponding to meter Pin 6;
Wiring of the L3 CT: S1 Line corresponding to meter Pin 7, S2 Line
corresponding to meter Pin 9.
C. RS485 cable wiring
Connect the RS485A to Pin 14 and RS485B to Pin 13 (The network
cables delivered with the inverter are labeled as 485-A and 485-B; if
you are using the cables purchased yourself, make sure to
differentiate between 485-A and 485-B.)
E. When connecting the smart meter to WIT, connect one end of
the cable to Terminal 13 (485B) and Terminal 14 (485A) of the
smart meter and the other end to Pin 6 (485A) and Pin 7 (485B) of
the COM1 port.
Note: In most cases, the red cable is used for 485A and the black
cable for 485B.
Red(484A)---COM1(6)
Black(484B)---COM1(7)
COM1
F. Dismantle the 16-pin connector delivered with WIT and set
aside the water-proof plug. Route the cables through each part
sequentially, then connect them to Pin 6 and Pin 7. Finally,
connect the connector to the COM1 port of the inverter.
G. The standard RS485 cable length is 15m. If a longer RS485
cable is required, please use an intact cable and make sure the
RS485 cable is less than 100m (the recommended length is less
than 25m).

The system wiring diagram is shown as follows. In case that the meter is not
operating properly, you can refer to it to check the wiring. For the Growatt
Storage/Hybrid Inverter, please connect the meter to the COM1 port.
1. Connect the L/N input and output cables correctly.
Please ensure that the input voltage and input current
are within the permissible range; otherwise the meter
will be damaged.
2. The input and output wires of the meter should be
correctly connected; otherwise, the meter will not be
able to operate properly.

Inverter
DTSU666 series three phase four wire electronic energy meter (din-rail) is designed based on power monitoring and energy metering
demands for electric power system, communication industry, construction industry, etc. as a new generation of intelligent instrument
combining measurement and communication function, mainly applied into the measurement and display for the electric parameters in the
electric circuit including three voltage, three current, active power, reactive power, frequency, positive&negative energy, four-quadrant
energy, etc. Adopting the standard DIN35mm din rail mounting and modular design, it is characterized with small volume, easy installation
and easy networking. It is compatible with Growatt Three-phase Storage/Hybrid Inverters.

Service and contact
Note: The communication address of the meter and the Growatt Three-phase Storage/Hybrid inverter is 04 by default, the baud rate is 9600.
If the meter fails to communicate with the inverter, you can check the parameter settings by following the instructions:
Button description: “SET” button represents“confirmation”,or“cursor shift”(when entering digits),“ESC” button represents “exit”, “→”（ ）
button represents“add”. The password is 701 by default.

Troubleshooting
Fault phenomenon
Reason analysis
Solution
Metering inaccuracy
1. Wiring error, check whether the corresponding
phase sequence of voltage and current is correct.
2. Check if the output line of the current transformer
is reversely connected.
3. The transformer ratio is not set, and the meter
displays the secondary data.
1. Refer to the wiring diagram to check the wiring.
2. If the transformer ratio setting is wrong, please
set the voltage ratio and current ratio correctly.
3. If the issue still exists, please contact your local
supplier.
RS485 communication error
(Inverter error 401)
1. The RS485 communication cable is
disconnected, short circuit or reversely connected.
2. The address, baud rate, data bit and parity bit of
the meter are not in accordance with the inverter .
1. If there is a problem with the communication
cable, please replace the communication cable.
2. Set the address, baud rate, data bit and parity bit
of the meter through buttons.
3. If the issue still exists, please contact your local
supplier.
