5.2 Mounting the Inverter
The inverter can be mounted to the wall or metal strut of module. The mounting holes
should be consistent with the size of the bracket or the dimensions shows below.
1. According to the figure 5.2, select the mounting height of the bracket and mark the
mounting holes. For brick walls, the position of the holes should be suitable for the
expansion bolts.
2.MAKE SURE the bracket is horizontal and the mounting holes A, B, and C (in
Figure 5.3) are in the correct points. Drilling the holes on the wall according
the marks.
WARNING:
The inverter must be mounted vertically on a vertical wall.
Use suitable expansion screws of bolts to attach the bracket
To the wall of rack as shown in figure 5.4.
The inverter should be mounted in a vertical position. The steps of mounting are as follows:
3. Using the expansion bolts to fix the bracket to the wall.
Install on a vertical surface or structure capable of bearing the weight.
Visibility of the LED status indicator lights and LCD display screen should be considered.
NOTE:
The inverter must be installed out of reach of children.
A minimum of 500mm clearance is required top, bottom, left and right of the inverter
(isolator enclosures excepted) for air flow and cooling.

5.3.1 Protective ground wire connection(PE)
For multiple inverters in parallel , all inverters should be connected to the
same ground point to eliminate the possibility of a voltage potential existing
between inverter grounds.
3) Strip the ground cable insulation to a suitable length as shown in Figure 5.7.
4) Insert the tripped wire into the OT terminal crimping area and use the hydraulic
clamp to crimp the terminal to the wire (as shown as Figure 5.8).
After crimping the terminal to the wire, inspect the connection to ensure the
terminal is solidly crimped to the wire.
5) Remove the screw from the heat sink ground point.
6) Use the screw from the ground point the attach the grounding cable.
Tighten the screw securely. Torque is 3Nm (as shown as Figure 5.9).
To effectively protect the inverter, two grounding methods must be performed.
Connect the AC grounding cable (Please refer to section 5.3.3)
Connect the external grounding terminal.
To connect the grounding terminal on the heat sink, please follow the steps below:
2) Prepare OT terminals: M4.
1) Prepare the grounding cable: recommend to use the 16mm² outdoor
copper-core cable.

3. Crimp the contact pin to the wire using a proper wire crimp tool as shown in Figure 5.14.
Figure 5.15 Connector with Cap nut Screwed on

Figure 5.16 Connect the DC Connectors to the Inverter
B) Connect the “DC+”and “DC-”to the input terminals; see Figure 5.10 and Figure 5.11.
A) Please make sure the polarity of the output voltage of PV array matches the
“DC+”and “DC-”symbols.
5.3.2 DC side connection
The steps of assembling the DC connectors are listed as follows:
2. Insert the wire into the connector cap nut and contact pin as shown in Figure 5.13.

4. Insert the contact pin into the connector housing until it locks in place. Screw the cap
nut onto the connector housing. Torque to 2.5-3Nm. (as shown in Figure 5.15)
5. Connect the finished DC cables to the inverter. A small click will confirm connection.
See figure 5.16.
If DC inputs are accidently reversely connected or inverter is faulty or
not working properly, it is NOT allowed to turn off the DC switch as it
will damage the inverter and even leads to a fire disaster.
The correct actions are:
*Use a clip-on ammeter to measure the DC string current
*If it is above 0.5A, please wait for the solar irradiance reduces until the
current decreases to below 0.5A.
*Only after the current is below 0.5A,
you are allowed to turn off the DC switches and disconnect the PV strings.
Please note that any damages due to wrong operations are not covered in
the device warranty.
Caution:

A) Strip the end of AC cable outer insulating jacket about 90mm then strip the end of each
wire about 15mm. (as shown in figure 5.17)

Note:
If the diameter of the protective jacket of the AC cable is less than recommended
(20K models: 17-25mm; 30K models: 21-30mm) spiral wound tape should be
used to increase the cable diameter to the recommended size.

Ensure the insulation of the cable is not into the terminal when tightening
the screws, otherwise it will cause poor contact.

2. Use the network wire stripper to strip the insulation layer off the communication cable.
Using the standard wire sequence referenced in TIA/EIA 568B, separate the wires in the
cable. Use a network cable crimp tool to trim the wire. Flatten the wire in the order shown
in Figure 5.25. Insert the wire into the RJ45 connector then crimp with the crimping tool.
3. Connect the RJ45 to COM2 or COM3, and tighten the nut.

6.2 Stop the inverter
1. Switch the Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the DC switch OFF or directly disconnect the DC output connector.
The LEDs and LCD of the inverter will be off within one minute.
6.1 Start the inverter
1. Switch the Supply Main Switch (AC) ON first.
2. Turn on the DC switch of PV array. If the voltage of PV array is higher than the start up
voltage, the inverter will turn on, and the initial interface of LCD will show “Current status:
Waiting” on the upper left corner.
3.When both the AC and DC are supplied to the inverter, it will be ready to generate power.
Initially, the inverter will check internal and AC parameters to ensure they are within
acceptable limits. At the same time, the green LED will flash and the LCD displays
INITIALIZING.
4. After around 30-180 second (based on local requirement), the inverter will start to generate
power. The green LED will be on continually and the LCD displays “Current status:
Generating.”
Current status: Waiting
Current status: Generating
NOTE:
If the DC input switch is ON before grid breaker, inverter may show fault message
“No_Grid” on current status, the fault will clear when grid voltage is normal.
