Recommended Cable Specifications
4 core outdoor cable (A, B, C, N) or 3
core outdoor cable (A, B, C)
Recommended cross sectional area of
conductor (copper):70 mm2
RS485 communication
cable
It is recommended to use a special
communication cable or 4-core or 2-core
shielded twisted pair cable with a
cross-sectional area of not less than
0.75 mm2.
It is recommended to use at least one
grounded dedicated cable with a
cross-sectional area of 35 mm2.
Note:
①The AC output has only 1 waterproof locks with a
specification of 65mm~70mm. When the screw is locked, use
the sleeve to calibration.
②The RS485 communication cable has only one waterproof
lock and the size is 18mm~25mm.
Output side cable connection
1. Crimping the OT terminal. Users need to prepare
the OT terminals themselves. The OT terminal
model of PE is M6, and the model ofAC is M10.
1) Strip the front end of the cable core.

2) Put on the heat shrink tubing and OT terminal.
3) Crimp the OT terminal.
4) Move the heat shrink tubing forward to cover
the seam.
5) Use a dryer to heat the sleeve to make it tight.
2. Ground connection:
Note: The ground cable must be reliably connected to the
grounding bar.
3. DC output cable connection：
1) Remove the lower door by 4# Allen wrench.
2) Tear off the AC output protective film and
install the waterproof lock.
Put in the
waterproof
lock parts
and screw
them
together
3) Screw off the locking cap of the AC output
waterproof lock.
4) The AC cables are connected to A, B, C and
N of theAC terminal row in turn, and the
fastening torque is 8N*m. Fasten the locking
cap after completion.
PV Input Cable Connection
1. Crimp MC4 terminal:
1) Confirm the positive and negative terminals of
the input cable and mark them.
Note: Please do not judge by the color of the cable
only, be sure to refer to the actual measurement.
2) Stripping with a wire stripper;

3) Press the cable together with the
corresponding core according to the correct
polarity.

4) Insert the core into the male and female ends
of the MC4 connector and tighten the
connector back cover according to the correct
polarity.
2. Remove the sealing plugs of the input terminals at
the bottom of the inverter. Connect the positive
and negative terminals of each input cable to the
PV+ and PV- input terminals of the inverter one by
one. Insert it until you hear a "click".
3. If there are unconnected input terminals, please
confirm that the unconnected input terminals
remain sealed by the plug.
RS485 Communication Cable Connection
The RS485 interface and anti-backflow interface
are located on the bottom of the machine. The
8-pin terminal is for RS485 network and the 4-pin
terminal is for the anti-backflow function.
1. Crimp the 485 terminal. Users need to prepare the
terminals themselves, and the terminals model
needs to match the 485 cable selected.(The 8-Pin
terminal needs to match GTVE10008 terminal.）
1) Strip the front end of the cable core.
2) Insert the terminal and crimp.
2. Take out the connector from accessories and
loosen the shell of the connector.
3. Pass the cables through the shell

2. Install the terminal to the bottom of the machine.
Tighten the connector shell.

5.Post-installation Check
1. Confirm that the inverter is securely installed in place
2. Check if the ground wire is properly connected,
whether the connection is reliable and secure, and
ensure that there is no open-circuit or short-circuit
3. Check that the output cable is properly connected, that
the connection is reliable and secure, and that there is no
open-circuit or short-circuit.
4. Check whether the DC input cable connection polarity
is correct, whether the connection is reliable and secure,
and ensure that there is no open-circuit or short-circuit.
5. Check if the RS485 communication cable connection is
correct and reliable.
6. Check if the inverter's lower door panel is replaced and
the door panel screws are tightened.
7. Check if the DC input terminals that are not needed are
sealed
