Grounding connection

1. Strip the 35-70 mm²grounding cable insulation

   • Select OT copper terminal (M8)
     

2. Pull the heat-shrink tubing over grounding cable
   

3. Insert the stripped section into OT terminal.

   • And crimp with crimping tool
     

4. Pull the heat-shrink tubing onto crimped section of OT terminal

   • The tubing must be at below stripped cable section
   • Use hot-air blower to shrink it so that they are in firm contact with
     

5. Connect the grounding cable to grounding point on the inverter

   • Tighten it with torque 10-12 N.m
     

Grid connection

1. Select the appropriate OT terminal and 70~240 mm² black, red and yellow and green copper cable

   • use wire stripper to strip the insulation layer of the AC cable end.
   • The stripped insulation layer shall be 2-3mm longer than “D” part of OT terminal as shown below.
     

2. Pull the heat-shrink tubing over AC cable.

   • Insert the stripped section into OT terminal and crimp with crimping tool
     

3. Pull the heat-shrink tubing over the crimped section of OT terminal.

   • Use hot air blower to shrink it so that they are in firm contact with OT terminal.
     

4. Un-install the screws on the cover to open the cover of the wiring box.

   • Use utility knife to cut out the pagoda type protection ring in accordance with the whole cable size,
   • Put the AC cable through the pagoda protection ring, and connect it to the AC terminals L1, L2, L3 and N in turn, and tighten it with torque wrench (with the torque of 25-30 N·m).
   • Re-install the cover of wiring box with the torque of 5~7 N·m.
     Separate PE cable
     
     Multi-core cable
       

Communication connection

1. Select 0.5~0.75 mm² twisted-pair and strip the 20-pin communication insulation

   • Insert the insulated cord end terminal into the cable end
     (ENY0512 nylon terminal for 0.5 mm²/22 AWG conductor;
     ENY7515 nylon terminal for 0.75 mm²/20 AWG conductor)

   • Clamp with terminals press clamp
     

2. Disassemble the communication terminal

   • Set the nut, claw, seal body, seal ring and body on the cable
     

3. Insert the tube type terminal into the housing according to the label

   • Push the terminal-inserted housing into the body; you will hear “Click” , if it is correctly inserted
   • Please check the following table for more details about corresponding Pin definition

• Keep the buttons on both sides pressed and then connect it to the communication port on the inverter. You will hear “Click” if it is correctly connected
  

Monitoring connection

Solaxcloud is a mobile phone application that can communicate with the inverter via WiFi/LAN/4G. It can realize alarm query, parameter configuration, daily maintenance and other functions. This is a convenient maintenance platform.

Plug Dongle into “USB” port at the bottom of the inverter. After the DC side or AC side is powered on, the APP and inverter can be connected. Please refer to the corresponding manual for details.

• WiFi connection
  Solax Pocket WiFi Dongle connects to a local network within 50 m of the installation to enable access to the SolaX Cloud monitoring platform.
  

• LAN connection
  If WiFi isn’t suitable, the Pocket LAN enables users to connect to the network via an ethernet cable. Ethernet allows for a much more stable connection with less interference.
  

• 4G connection
  SolaX Pocket 4G dongle allows you to use a 4G connection to monitor your system without the option of connecting to a local network. (This product is not available in the UK)
  

• Basic setting
  Basic settings can set the time, date, language and system switch.
  

• Advanced setting
  Advanced settings can set the new password of the inverter, buzzer enable, timing switch, etc.
  

  • Under different standard codes, the parameters that can be set for the inverter are different.
  • If you change the grid standard code, some parameters may revert to factory defaults. After the grid standard code is changed, please check whether the previously set parameters are affected.
  • Sending reset, plant recovery, shutdown or upgrade instructions to the inverter may cause the inverter to be unable to be connected to the grid and affect power generation.
  • The power grid parameters, protection parameters, characteristic parameters and power regulation parameters of the inverter must be set by professionals. power grid Incorrect setting of parameters, protection parameters and characteristic parameters may cause the inverter not connected to the grid and incorrect setting of power adjustment parameters.
  • The error may cause that the inverter cannot be connected to the power grid according to the power grid requirements, thus affecting the power generation.
  • Parameter name, ranges, and defaults may change or adjust in the future.
