cabinet with a su󰀩cient IP rating. Build sunshade & rain shelter to avoid direct exposure to sunlight and
rain for outdoor application.
!CAUTION
⁎Do NOT expose battery into sunshine or rain directly.
⁎Keep the dirt or dust at a minimal level.
⁎ Do not install battery in a place where ood frequently occurs.
⁎Do not install battery in highly humid area.
⁎Ensure direct contact between battery shell and ambient air and do NOT cover or shield battery.
5.1 Battery Orientation
The battery supports stackable installation with brackets. At most 8 batteries can be athwart stacked.
Ensure that you install the battery in correct directions. Please refer to gures below (√ means acceptable
and X unacceptable).
5.2 Stackable Installation with Bracket Support
!CAUTION
Before installing battery, remove conductive ornaments such as watch, bracelet, and rings and wear protection
equipment.

6.1 Prepare Cables
Before connecting the batteries, you need to prepare grounding wire with OT lugs to meet the
requirements of your applications.
!CAUTION
Cables can be made by yourself or purchased from qualied providers.
It is recommended to purchase nished power wire products according to the terminal specications of the battery.
If you make cables on your own, please ensure that the terminals are crimped properly.
Make grounding wires with OT terminals.
Step 1 Strip cable sheaths and put a piece of heat shrinking tube
along the wire. Grounding: 16 mm²
Step 2 Insert conductive wires into an OT terminal.
M6
Step 3 Crimp the OT terminal with a hydraulic plier.

Step 4 Use a heat gun to heat the heat shrinking tube.
6.2 Connect One Battery
!CAUTION
⁎ Ensure that battery is in o mode and battery breaker is turned o.
⁎Ensure that no cable is twisted after battery is wired.
After making the cables ready and equipping yourself with protective devices, connect cables to the
battery in the following way:
Step 1 Use an M6 screw to fasten the grounding wire to grounding terminal and x the other end to the
inverter directly.
Note that the cross-section of grounding wire is 16mm2.
Cross-head screwdriver
Step 2 Insert a network cable into battery port.
1. Plug one end of network cable A into the PCS port of battery, and plug the other end into the network
port of the inverter.
2. Insert two terminators (a crystal plug with pin 4 and pin 5 short circuited) into Link-Out and Link-In
respectively.

Step 3 Connect power wires.
1. Fix the OT terminals of power wires to one pair of the +/- terminals of the battery.
2. Put back the plastic cover.
3. Fix the other ends to a breaker and then connect to the inverter.
!CAUTION
⁎ When connecting a power wire, ensure that its OT terminal is placed in the correct direction.
⁎ Do NOT stack two OT terminals onto one power interface.

6.3 Connect Batteries in Parallel
!CAUTION
⁎ Ensure that all batteries are in o mode and battery breakers are turned o.
⁎Ensure that no cable is twisted after batteries are wired.
⁎ The batteries shall be manufactured within one year and have a cycle dierence less than 300.
Step 1 Conrm that the voltage di󰀨erence is not greater than 1V.
1. Power on the batteries without load and use a multi-meter to measure their voltages.
2. If the voltage di󰀨erence is greater than 1V, charge the battery with lower voltage.
3. Power o󰀨 the batteries.
Step 2 Connect network cables.
1. Insert one end of network cable A into the PCS port of Battery 1 and the other end into the network
port of the inverter.
2. Insert a terminator (a crystal plug with pin 4 and pin 5 short circuited) into Link-In of Battery 1.
3. Use network cable B to connect the Link-Out port of Battery 1 and the Link-In port of Battery 2.
Connect the rest batteries in a similar way till the last one is connected.
4. Insert a terminator (a crystal plug with pin 4 and pin 5 short circuited) into Link-Out of Battery 4.

7 Operation and Commissioning
After the battery is installed and wired, operate and commission it to check if the battery works properly.
!CAUTION
When operating or commissioning the battery, please strictly follow the safety instruction below:
⁎Technicians must go through technical training and obtain certificates in compliance with local laws and
regulations.
⁎Please stand on dry insulating objects and do not wear metal objects such as watches, rings and necklaces
during operation.
⁎Use insulating tools and wear protective devices.
⁎ Do not contact with two charged positions with a potential dierence.
⁎ Hang a prohibition sign that stops people from turning on the breakers on the power distribution equipment
if needed.
⁎If any abnormality is detected, immediately power off the battery. Proceed again only after causes are
conrmed.
7.1 Power on Battery
Power on the battery in either of the following ways:
Keep the inverter on and turn on battery breaker(s). The battery(s) is activated after detecting a voltage
from the inverter.
Alternatively, hold the Power button on battery for over one second.
If LED1 to LED6 are lit on one by one and SOC indicators on all batteries indicate SOC correctly,
batteries are powered on successfully.
After the battery(s) is powered on, observe it for 15 minutes to conrm that it can charge and discharge
properly.
7.2 Power o Battery
Hold the Power button of the single battery or one battery in parallel connection for over two seconds.
LED1 to LED4 and LED6 icker for 2 times, and the battery(s) turns o󰀨.
