Negative terminal Positive terminal
Step 2. Use a wire stripper to strip the 7mm insulation layer of the wire end.

Step 3. The PV connector is divided into 2 parts, to the plug and the fastening head. Pass the cable through the fastening head and the alignment plug. Note that the red and black lines correspond to different pairs of plugs. Finally, force the cable into the plug and hear a “click” to indicate that the connection is complete.

Step 4. Tighten the fastening head and into insert the corresponding positive and negative (PV-/PV+) parts of the inverter.

Grid and Load Output Connection

Step 1. Prepare a Grid cable (three-core wire) and an Load cable (two- core wire), and then find the European terminal and waterproof cover in the accessory bag.

Step 2: The Grid and Load cables go through the corresponding Grid and Load ports of the waterproof cover. Remove the 12mm insulation layer at the end of the wire. Insert the European-style terminals respectively, and make sure that the stripped ends are inserted into the European-style terminal ,and finally use crimping pliers to press tightly.

Step 3. Find the location of the AC interface on the inverter, insert the crimped terminals into the UW10 terminals L1, N, and L2 according to the wire sequence, and use a flat-blade screwdriver to tighten the screws. (Torque: 0.2±0.1N ·m) Install the AC waterproof cover, and tighten the screws on the four sides of the waterproof cover with an Allen wrench. Tighten the waterproof fastening head.

Battery Connection

Step 1. Prepare 8 AWG battery power line, find the DC plug (+), DC plug (-) in the accessory bag.

Step 2.  Insert the striped cables into the DC plug (-) and DC Plug (+) respectively

Step 3. Press down on the spring by hand, you can hear a click sound, then push the ends together, and tighten the screw joints.

Step 4. Insert the battery power lines into the corresponding BAT port (+), (-) of the inverter.

Note: BAT port, not PV port!
Note: The positive and negative wires of the battery are not allowed to be reversed!
Notice!
After the BMS communication between the battery and the inverter is finished, the battery will work normally.

COM PIN Definition

**** Customers can communicate or control the inverter and external devices through the COM interface. Professional users can use pins 4 and 5 to realize data acquisition and external control functions. The communication protocol is Modbus RTU. For details, please contact SolaX. If the user wants to use the inverter dry contact to control external equipment (such as a heat pump), it can be used with SolaX’s Adapter Box. For details, please refer to the Quick Installation Manual of the Adapter Box.tery must be consistent with the definition of pins 4, 5, 7, and 8 above;

Grounding Connection(manodatory)

Step 1. Prepare a one-core cable (10AWG), and then find the ground terminal in the accessories

Step 2. Strip the grounding cable insulation(length”L2), insert the stripped cable into the ring terminal, and then clamp it.

Step 3. Find the ground connection port on the inverter, and screw the ground wire on the inverter with an M5 Allen key.

COM Connection Steps

Step 1. Prepare a communication cable, and then find the communication adapter in the accessory bag.

Step 4. Tighten the completed BMS / CT / COM communication line and tighten the waterproof plug.

Step 5. Finally, find the corresponding BMS / Meter / CT / COM ports on the inverter and insert the communication cable into the corresponding ports.

Monitoring Operation

Wireless monitoring accessories connection steps:
Step 1. First find the DONGLE port of the inverter.

Start the Inverter

After the inverter is checked, then conduct the following steps

1. Make sure that the inverter is fixed on the wall.
2. Ensure that all ground wires are grounded.
3. Confirm that all DC lines and AC lines are connected.
4. Make sure the CT is connected.
5. Make sure the battery is well connected.
6. Turn on the Grid switch and Load switch
7. Turn on the battery switch.

Start the inverter

• Steps to start the inverter
  • Turn on the AC switch between the X1-SPT and the power grid.
  • (Optional) Remove the locking screw from the DC switch.
  • Turn on the DC switch between the PV string and the X1-SPT if there is any.
•  Turn on the DC switch at the bottom of the X1-SPT .
• When the photovoltaic panel generates enough power, the inverter will start automatically. Check the status of the LED screen, the LED is green.
  • If the LED is not green, please check the following:
  • All connections are correct.
  • All external disconnect switches are closed.
  • The DC switch of the inverter is set to the “ON” position.
  • All external disconnect switches are closed.
  • The DC switch of the inverter is set to the “ON” position.
