Step 1: Bracket installation

Fasten the brackets to the wall, according to the following steps:

Fix the inverter bracket on the bracket B.

    Inverter bracket
Then set the bracket B on the bracket A and fix it with screws.


Note: When installing the bracket, be sure to use a spirit level to test and keep the bracket parallel to the horizontal plane. Bracket A should be installed at a distance of 300mm (at least) from the ground.

Step 2: Screw the brackets on the wall

a) Use the bracket as a template to mark the two holes on the wall with a marker pen. Drill holes at marked spots with a depth of 80mm.

b) Insert expansion bolts into the holes and use a rubber hammer to knock the expansion screw bolts into the wall.

c) Align the bracket with the screws and use an inner hexagonal wrench to screw the tapping screw until the expansion bolt bang is heard.

5. Monitor the antenna connections of accessories
There is an antenna in the box of monitoring accessories. a) Install the antenna on the box and tighten it by hand; b) Then connect the antenna cable to the end of the WiFi Dongle.
6.Wiring Connection
6.1 Inverter side connection_PV(INV)
According to the PV 1(INV )+/PV1(INV )-/PV2(INV )+/PV2(INV )-/BAT(INV )+/BAT(INV )- line symbol on X3Matebox advanced harness, the corresponding ports of PV 1+/PV1-/PV2+/PV2-/BAT+/BAT- of the inverter are successively inserted.

Pass the PV line through the PV port of the X3-Matebox advanced, and then nd PV(PV1+/PV1/PV2+/PV2+) inside the X3-Matebox advanced. Force the wire harness directly into the hole to jam, gently twist not to loosen.

Note: For 5.0 kw and 6.0 kw M series, there is only one PV1 line, and PV1+/PV1corresponds to any pair of PV1+/PV1- ports on X3-Matebox advanced.

Pass the Grid/Load line through the Grid/Load port of the X3-Matebox advanced, then nd the Grid(R/S/T/N) port and Load (R/S/T/N) ports in the X3-Matebox advanced, insert each line, and use the screwdriver to lock the screws.

6.3 Ground wire connections
The box needs to be grounded as follows.
Hexagon keys Torque: 1.5±0.2N·m

Note: 5.0 kw and 6.0kw M. series inverters have only two MPPT and two PV strings, so when connecting, you need to unplug / of the PV in the X3-Matebox advanced. -Use a screwdriver to press down the yellow part while pulling the wire out of the port.
6.2 X3-Matebox advanced side connection – Grid(INV) and EPS(INV)

Connect the Grid(INV ) R/S/T/N and EPS (INV) R/S/T/N/PE ports of the inverter to the X3-Matebox advanced port. The connection method is as follows : a) First, insert the R/S/T EPS(INV ) into the R/S/T port of EPS (INV ) in X3-Matebox advanced and the N EPS(INV) directly into the hole, directly into the hole and ensure that the installation is tight ; b) Then nd the Grid(INV) (R/S/T ) port in X3-Matebox advanced, connect the corresponding wire harness, and lock the screw with a screwdriver. C) Finally, lock the PE wire/N wire with a hexagonal keys;
