SolaX Power X3-Matebox User manual

X3-Matebox is a critical part for SolaX all in one energy storage
system, which integrates the DC breaker/AC breaker/switch unit/CT
and so on, it can easily be installed compare to the traditional
separate system, this unit can be used with SolaX X3-Hybrid G4 and
X3-Fit G4 series inverters.
There are 2 wiring diagrams for your system connection reference,
please follow your local policy to chose which one is suitable for
your side.

3. Preparation
The following tools need to be prepared before installation:
4. Mounting
The bracket of the X3-Matebox is composed of three parts. A is used to install the X3-Matebox Bracket
, B is used to fix the bracket position of the inverter , and C is used to fix the bracket Bracket Bracket
position of T-BAT-SYS-HV-(3.0) .
The bracket can be installed in two ways:
1)With T-BAT-SYS-HV-(3.0) battery, the installation method is as follows:( )
2)With other batteries, the installation method is as follows:( )
Note :When installing the bracket, be sure to use a level to test and keep the bracket parallel to spirit
the horizontal plane.
Bracket A should be installed at a distance of 200mm（at least） from the earth.

Step 1: Splicing bracket
First splice the inverter bracket, bracket A, bracket B, and battery bracket according to the following
steps, and then fasten them to the wall.
Bracket C
Then set the bracket C on
the bracket A ;
Then the bracket C is fixed on
the battery bracket and the
screws are locked ;
Then set the bracket B on the
bracket A and fix it with screws;

Step 2: Then install the T-BAT-SYS-3.0 battery bracket ;(Please refer to
T-BAT-SYS-3.0 battery quick installation guide)
Step 3: Mounting bracket A
80.00 mm
Use a level first to ensure that the brackets (battery bracket, bracket A, bracket B, bracket C, inverter
bracket) in the system are firmly installed and level. Then follow the steps below to hang X3-Matebox.
X3-Hybrid G4 inverter
a)Before install the inverter, connect the ground wire
firstly,and remove the "DONGLE" waterproof cover (for
the installation of communication accessories;(Please
refer to the pocket dongle(WiFi) quick installation guide)
b) Firstly install the battery and inverter on the wall,
and then install the X3-Matebox on the wall;
Step 4: Finally, install X3-Hybrid G4 inverter bracket ;(Please refer to
X3-Hybrid G4 inverter quick installation guide).
Step 5. Install the X3-Matebox on the wall and lock the screws.

6.1 Inverter side connection
According to the PV 1(INV)+/PV1(INV)-/PV2(INV)+/PV2(INV)-/BAT(INV)+/BAT(INV)- line symbol on X3-Matebox
harness, the corresponding ports of PV 1+/PV1-/PV2+/PV2-/BAT+/BAT- of the inverter are successively inserted.
6. Wiring Connection
6.2 X3-Matebox side connection
1) Connect the Grid(INV) L1/L2/L3/N and Off-grid (INV) L1/L2/L3/N/PE ports of the inverter to the
X3-Matebox port. The connection method is as follows :
a) First, insert the L1/L2/L3 Off-grid(INV) into the R/S/T port of Off-grid (INV) in X3-Matebox and
the N Off-Grid(INV) directly into the hole, directly into the hole and ensure that the installation is tight ;
b) Then find the Grid(INV) (R/S/T) port in X3-Matebox, connect the corresponding wire harness, and lock the
screw with a screwdriver.
C) Finally, lock the Grid (INV) PE wire with a hexagonal keys;

2) PV(PV1+/PV1-/PV2+/PV2-) /Gird(L1/L2/L3/N/PE) /Load(L1/L2/L3/N) side connection
a) Prepare ordinary PV(PV1+/PV1-/PV2+/PV2-) /6mm² Gird(L1/L2/L3/N/PE) /6mm² Load(L1/L2/L3/N) wire,
remove the 12mm insulation layer at the end of the wire .Insert The European-style terminals respectively.
The stripped terminals must be inserted into the European-style terminals and finally pressed down with the
crimping pliers. Grid(L1/L2/L3/N) Load(L1/L2/L3/N)
