4.3 Installation Location
Make sure that the installation location meets the following conditions:
The installation site must be suitable for the size and weight of the battery.
Must be installed on a firm surface to sustain the weight of battery.
The area is water proof.
There are no flammable or explosive materials in proximity
The ambient temperature is within the range from 0°C to 45°C.
The temperature and humidity is maintained at a constant level.
There is minimal dust and dirt in the area.
Installation must be vertical or tilted backwards by maximum 15° - avoid forward or sideway stilt.

- 8 -
CAUTION
If the ambient temperature is outside the operating range, the battery pack stops operating to protect
itself. The optimal temperature range for the battery pack to operate is 0°C to 45°C. Frequent exposure
to harsh temperatures may deteriorate the performance and life of the battery pack.
4.4 Minimum clearances
Observe the minimum clearances to walls, other batteries or objects as shown in the diagram and
picture below in order to guarantee sufficient heat dissipation

4.5 Installing the Battery Pack
WARNING
In order to avoid electrical shock or other injury, inspect existing electronic or plumbing installations
before drilling holes.
The battery is heavy, please handle with care to avoid damage to the product or injury to the installer.
1.Choose suitable firm wall with thickness greater than 100mm.
2.Use the mounting frame as a template, mark the hole position.
3.Drill 6 holes according to the hole position, it is ø16 with depth 100mm.
4.Hammer the M10 screws to the above holes, and screw the nut.

- 9 -
5.Raise the battery to slightly above the hook, while maintaining the battery balance. Secure the
battery to the wall through a hook.
WARNING
A falling device can cause serious or even fatal damage: never install the battery on the hook screw
unless you ensure that the hook screws are firmly installed on the wall and after a thorough inspection.
4.6 Parallel use of battery
When the battery needs to be used in parallel, the maximum connection is 10 units, but we recommend
using 2-4 units according to the application, please select the appropriate accessories:
Method of connecting two batteries in parallel
a) The positive/negative electrode of each battery is directly converging at the battery input end of the
inverter;
b) The two batteries should be connected in parallel first. The battery near the inverter is the main
output and connected to the battery input terminal of the inverter. (The wire required for the confluence is
not included in the standard package)

- 10 -
More than 3 batteries in parallel require the use of an additional bus box (not included in the
standard package).
In this example, four batteries are connected in parallel using one bus box.
1. Please refer to the following figure for the positive output line A.C.E.G. connected to the battery
terminal and the negative output line B.D.F.H.
2. Connect the other end of the battery A.C.E.G. to the positive copper bar J1 of the bus box. The
negative B.D.F.H is connected to the negative copper bar J2 of the bus box.
3. Connect the J1 to the positive terminal of the inverter.
4. Connect the J2 to the negative terminal of the inverter.
5. Add an appropriate isolation switch if necessary.
4.7 Communication Connection
4.7.1 Communication Address Setting
Please refer to the table below to set up the master and slave batteries. Duplicate address bits in the list
of address Settings (from 1 to 6 batteries) cannot be used for communication.

4.7.2 Communication between battery and inverter
1) Independent communication
When the single machine is used, the battery is set as the host and communicates with the inverter via
RS485A/CANBUS;

- 12 -
2) Parallel communication
When multiple batteries are used in parallel, the batteries are connected in parallel through the RS485B
communication interface; The battery near the inverter is set as the host and communicates with the
inverter via RS485A/CANBUS;
