Please reserve enough distance from the equipment to the ceiling/ground for capacity expansion.
Take Scheme C as an example.
Step 1: There are two ways to install Transverse Plate to Base Support due to 4 kinds of Stub Spacing, with details as follows: (a) 28 in./711.20 mm or 32
in./812.80 mm; (b) 20 in./508.00 mm or 24 in./609.60 mm.
(1) Insert Transverse Plate to Base Support;
(2) Secure the Transverse Plate and Base Support using screws (2×M5*8 countersunk head screw) (Tighten torque: 2.2-2.5 N·m). See figure below.

Step 7:
(1) Attach the M5 * 10 screw to Wall Bracket but be sure not to tighten;
(2) Place such Wall Bracket to the wall, align its holes to the holes on the Battery
Module, and use a spirit level to ensure it's even;
(3) Accurately mark the location of the Wall Bracket on both sides with a pen;
(4) Circle along the inner ring of the holes;
(5) Remove the Wall Bracket, and then drill the two holes (at least 3.54 in./90 mm) by
a Drill (
φ
0.39 in./10 mm).
Electric drill dust collector is recommended.
Note!
Step 8: Place Expansion Bolts into the two holes (the Expansion Bolt is not required in
case of solid wood wall).

Commissioning
If the batteries have not been used for more than 9 months, these batteries must be charged to at least SOC 50 % each time.
For the first installation, the interval among manufacture dates of battery modules shall not exceed 3 months.
If a battery is replaced or added for capacity expansion, each battery's SOC should be consistent. The max. SOC difference should be
between ±5%.
If users want to increase their battery system capacity, please ensure that the SOC of the existing system capacity is about 40%. The
manufacture date of the new battery shall not exceed 6 months; in case of exceeding 6 months, please charge the new battery to around
40%.
Black Start: Press the POWER button and hold it for 20 sec; release the button after the four SOC indicators flash blue alternately. But, we
do not recommend the use of Black Start as it may cause the port to be charged, resulting in an electric shock.
Steps for commissioning are shown
as
follows
:
①
Press the left side door panel
②
Open the air switch's guard and toggle switch, to ensure that
the inverter does charge to the battery
③
Press the right side door panel
④
Press the button for 1 to 2 sec, and then the system starts

The equipment can support capacity expansion.
There are two circumstances in case the user wants to increase a battery module:
1. For floor mounting, remove the inverter before increase of battery module;
2. For wall mounting, if the distance from the equipment to the ground is enough, do not remove the inverter; otherwise, the inverter shall
be removed.

Making a BMS communication cable
To ensure normal operation of BMS and inverter, a BMS communication cable is
required to be made before wiring.
The specific definition of the communication cable is shown as follows:
The wire order of the communication cable is as follows:
1 2 3 4 5 6 7 8
1) Orange stripes on white
2) Orange
3) Green stripes on white
4) Blue
5) Blue stripes on white

20 in/508.00 mm
24 in/609.60 mm
Note: The bubble spirit level on the Transverse Plate can be used as an auxiliary tool, additionally, please prepare a spirit level to measure whether the Plate is even or not.
Step 12:
(1) Attach the M5 * 10 screw to Wall Bracket but be sure not to tighten;
(2) Place such Wall Bracket to the wall, align its holes to the holes on the
Battery Module, and use a spirit level to ensure it's even;
(3) Accurately mark the location of the Wall Bracket on both sides with a
pen;
(4) Circle along the inner ring of the holes;
(5) Remove the Wall Bracket, and then drill the two holes (at least 3.54
in./90 mm) by a Drill (
φ
0.39 in./10 mm);
(6) Place Expansion Bolts;
(7) Secure Wall Brackets using Tapping Screws and Gaskets. Refer to the
Steps 7, 8, 9 and 10.

Step 2:
(1) Place the assembled Transverse Plate and Base Support on the wall, look
the cylindrical plastic bubble spirit level on the Transverse Plate. If the bubble
isn't in the center, slightly bow it to the horizontal.
(2) Then determine the position of holes.
(3) Mark it with a pen.
(4) Remove it and drill the four holes (at least 3.54 in./90 mm) by Drill (
φ
0.47
in./12 mm for concrete wall, or
φ
0.31 in./8 mm solid wood wall).
Note: In case of solid wood wall, please directly tighten the screws with
torque wrench instead of hammering them with rubber mallet.
Note: The distance from the Base to the ground is
decided according to the local regulations.
