Inverter Installation

Please make sure the inverter will be installed with a proper distance as shown below.

Step 1: Fix the bracket on the wall

Choose the place you want to install the inverter. Place the bracket on the wall and mark the position of the 4 holes from bracket.

Drill holes with electric drill, make sure the holes are at least 50mm deep, and then tighten the expansion tubes.

Insert the expansion tubes into the holes and tighten them. Install the bracket with the expansion screws.

Step 2: Install the filter on top side (for fan cooling inverter)

Put the filter into the right position as shown by below figure. Align the long legs on both side of the filter with the outermost fin.

Please keep the top of fliter flush with the back of inverter.Please adjust to the position where the lateral fins can be seen from the holes on both sides of the filter according to the figure in which the arrow towards to the wall.

Press the filter down from the top. Check if all fins are covered by filter.

Ensure that the filter is installed and secured in right position.

Please keep the filter edge flush with the back of inverter, and install into right position.

Please keep the bottom side of the filter edge flush with the top sides of fins, and install into right position.

Step 3: Match the inverter with wall bracket
Mount the inverter to the bracket. Secure the inverter with the M5 screw and washer.

Please refer to the correct installation method to insatall：

Wiring Steps

AC Wiring

• Cable dimensions

Power (kW)| 3.0| 4.0| 5.0| 6.0| 8.0| 10.0| 12.0| 15.0| 17.0| 20.0| 23.0| 25.0
---|---|---|---|---|---|---|---|---|---|---|---|---
Cable| 2.5~6mm²| 4~6mm²| 6~10mm²| 10mm²
Micro-Breaker| 16A| 25A| 40A| 50A| 60A

• Trim all the wires to 52.5mm and the PE wire to 55mm.
• Use the crimping pliersto trim 12mm of insulation from all wire ends asshown in the picture.
  

Note : Please refer to local cable type and color for actual installation.

• Separate the AC plug into three parts.

• Insert the sleeve assembly into the cable.

• Install the copper wire into the plug terminal and lock the screw.
  

• Lock the lock nut and the sleeve(3~5N·m), lock the sleeve and the plug(1.5~1.7N·m).

• Insert the plug assembly into the socket (inverter end) and lock each other by the coupling twist.

DC Wiring

• Turn off the DC switch.

• Choose 2.5 mm² wire to connect the PV module.

• Trim 6mm of insulation from the wire end.
  

• Separate the DC connector as below.
  

• Insert striped cable into pin contact and ensure all conductor strands are captured in the pin contact.

• Crimp pin contact by using a crimping plier. Put the pin contact with striped cable into the corresponding crimping pliers and crimp the contact.

• Insert pin contact through the cable nut to assemble into back of the male or female plug. When you feel or hear a “click” the pin contact assembly is seated correctly.
  

Grounding Wiring
Screw the ground screw with screwdriver as shown below

Communication and Monitoring
This series of inverters provide two RS485 ports. You can monitor the inverter via RS485. Another RS485 port is used to connect a smart meter (stand-alone anti- backflow function). Maximum torque of lock wire is 0.2N·M. The PIN definitions of RS485/DRM0/ESTOP interface are as below.

1. There are two different types of communication connectors.
2. The pin definication for both connector are the same.
3. Maximum torque of lock wire is 0.2N·M for both connector.

Startup Procedure

1. Atier checking all connecions are correct, turn on the external DC /AC
   breakers.

2. . Turn the DC switch to “ON” position.

3. lnverter will start automatically when PV panels generate enoug energy, the LED will flash.

4. Complete inverter Start-up guide

Atier the initial start-up the inverter, display will go to the language setings page, short press to switch language and long press to confirm selection. Once language set, display will guide to set the safety regulation. Short press to switch safety regulation, and long press to confirm selection.

Note

• Please select the correct country code
• Set the thme on the inverter using the button or by using the APP
• Please DO NOT apply USB3.0 on inverter USB port, the inverter USB port only support for USB2.0.
