3. Insert expansion bolt into the hole, use rubber hammer to knock the expansion screw bolt into the wall.
4. The bracket is aligned with the screw uses the inner hexagonal wrench to screw the tapping screw until the expansion bolt “bang” is heard.
5. Hang the buckle on the inverter to the corresponding position of the backplane.
6. Use the inner hexagonal wrench to tighten the inner hexagonal screw on the right side of the inverter.

PV Connection

• The PV port wiring of X3-Hybrid G4 M series inverter has been completed. For specific installation details, please refer to the X3- Matebox Quick Installation Guide, the D series needs to be wired according to the following steps.

  • Step 1. Turn off the DC switch, connect the PV module, prepare a 12AWG PV cable, and find the PV (+) terminal and PV (-) terminal in the package.

  • 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+) ports of the inverter.
    Note: Before inserting the PV terminal, please turn on the switch of the PV module, and use a multimeter to measure the positive and negative poles of the PV terminal port to prevent reverse connection

Start Guide

1. Set date time
2. Set language
3. Set the safety standard
4. 4. CT/Meter Setting
5. Set export control
6. Set work mode
7. X3-Matebox Setting

*.Export Control
This function allows the inverter able to control energy exported to the grid.
There are user value and factory value.
The factory value is default which can not be charged by user.
The user value set by installer must be less than the factory value.

Set work mode

There are 4 work modes for choice. Self use/ Back Up Mode/ Feed in Priority/ Force Time Use
All these work modes is available for on-grid condition only:

Name / Description

Self Use
The self-use mode is suitable for areas with low feed-in subsidies and high electricity prices.

1. When the power of PV is sufficient
   Active Charging or Discharge time period: PV will power the loads firstly, and surplus power will charge to the battery .
   If the battery is fully charged, then sell the surplus power to the grid;( The inverter will limit the output if Feed-in limit or zero feed-in is needed ) (PV＞Load ,PV →Load→Battery → Grid)

2. When the power of PV is insufficient
   Active Charging time period: PV will power the loads firstly ,the remaining power will be taken from the grid , the battery will not discharge at this time.(PV＞Load ,PV + Grid → Load)
   Active Discharge time period: PV+BAT will power the loads together. If the power is still not enough, the remaining power will be taken from the grid. (PV＜Load ,PV + Battery + Grid → Load)

3. Without PV power
   Active Charging time period: The grid supplies the loads and also can charge the battery.(PV=0 ,Grid →Load + Battery)
   Active Discharge time period: The battery will power the home loads firstly. If the battery power is not enough ,the remaining power will be taken from the grid .The inverter will enter into the standby state.(PV=0 ,Battery+Grid→Load)
   Battery min SOC can be set:10%-100%.

Feed-in priority
The Feed-in priority mode is suitable for areas with high feed-in subsidies, but has feed-in power limitation.

• When the power of PV is sufficient
  Active Charging time period :PV will power the loads firstly, and surplus power will feed-in to the grid. If the feed-in power has been limited ,the surplus power can charge the battery. (PV ＞ Load, PV → Load → Grid → Battery)
  Active Discharge time period: PV will power the loads firstly ,and surplus power will feed-in to the grid. (PV＜Load, PV → Load → Grid )

• When the power of PV is insufficient
  Active Charging time period :PV will power the loads firstly, the remaining power will be taken from the grid. The battery will not discharge.(PV＞Load,PV

• Grid → Load)
  Discharge time period: PV+BAT will power the loads together. If the power is still not enough, the remaining power will be taken from the grid. (PV＜Load , PV + Battery + Grid → Load)

  • Without PV power
    Active Charging time period :The grid will power the home loads and also charge the battery. (PV=0 , Grid → Load + Battery)
    Active Discharge time period :The battery will power the home loads firstly .If the battery power is not enough, the remaining power will be taken from the grid .The inverter will enter into the standby state.(PV=0 , Battery+Grid → Load)
    Battery min SOC can be set:10%-100% .

Backup mode
The back-up mode is suitable for areas with frequent power outages. Same working logic with “Self-use” mode.
This mode will maintain the battery capacity at a relatively high level.(Users’ setting) to ensure that the emergency loads can be used when the grid is off. Customers no need to worry about the battery capacity.
Battery min SOC can be set:30%-100%.Backup mode SOC adjustment range :30%-100%; In Backup mode, SOC-min under off-grid condition is 10%, which cannot be modified.

Off-grid
The off-grid mode is used when the power grid is off .System will provides emergency power through PV and batteries to supply power to the household loads. (Battery is necessary )

1. When the power of PV is sufficient
   PV will power the loads firstly, and surplus power will charge to the battery.(PV＞Load, PV → Load → Battery)

2. When the power of PV is insufficient
   The remaining power will be taken from the battery.(PV＜Load, PV+battery → Load → Battery)

3. Without PV power
   The battery will power the emergency loads until the battery reached the min SOC, then the inverter will enter into the idle mode.(PV=0, Battery → Load)

Firmware Upgrading

• In order to upgrade the firmware smoothly, if the DSP and ARM firmware needs to be upgraded, please note that ARM firmware must be upgraded
  first, then DSP firmware!

• Make sure that this directory is completely consistent with the above table, do not modify the firmware file name, Otherwise, the inverter may not work!

• For X3-Hybrid G4, ensure that the PV input voltage is greater than180V (upgrade on sunny days). please ensure that the battery SOC is greater than 20%
  or the battery input voltage is greater than 180V. Otherwise, it may cause serious failure during the upgrade process!

• If the ARM firmware upgrade fails or stops, please do not unplug the U disk and power off the inverter and restart it. Then repeat the upgrade steps.

Upgrade preparation

1. Please check the inverter version and prepare a U disk (USB 2.0) and personal computer before upgrading.
2. Please contact our service support through service@solaxpower.com to obtain the firmware, and store the firmware in the U disk according to the
   following path.
   Update :
   For ARM file:“update \ARM\618.00406.00_Hybrid_X3G4_ARM_V1.01.0710.usb”;
   For DSP file:“update\DSP\618.00405.00_Hybrid_X3G4_DSP_V1.01.0710.usb”;

Upgrade steps
