1. Safety Precautions

1.1 General

Caution

1) It is very important and necessary to read the user manual carefully before installing or using the battery. Failure to do so or to follow any of the instructions or warnings in this document can result in electrical shock, serious injury, or death, or can damage the battery, potentially rendering it inoperable.

2) After unpacking, please check the product and packing list first, if the product is damaged or missing parts, please contact the local retailer.

Warning

3) Only qualified professionals or trained personnel are allowed to install, operate, maintain, or replace the equipment and components (including software).

1.2 Before Connecting

Danger

1) Before installation, be sure to cut off the grid power and make sure the battery is in the turned-off mode. Transient contact between the core of the power cable and the conductor will generate electric

arcs or sparks, which may cause fire or personal injury.

2) Ensure that the cables you prepared meet local regulations.

3) Wiring must be correct. Do NOT misconnect the positive and negative cables. Also, avoid short circuit with any device. To avoid electric shock, the copper and contact of the wire should NOT expose outside without protection.

4) It is prohibited to connect the battery and AC power directly.

5) Do not connect the battery with PV solar wiring directly.

6) The embedded BMS in the battery is designed for 51.2 VDC, please DO NOT connect the battery in series.

7) Please ensure the electrical parameters of the battery system are compatible with related equipment.

8) Keep the battery away from water and fire.

9) Do not expose battery to flammable or harsh chemicals or vapors.

10) Obtain approval from the national and local electric utility company before connecting the equipment to the grid.

1.3 In Use

Notice

For the first use, it is highly recommended to recharge the battery to full (more than 90%) of the capacity.

Danger

1) All the battery terminals must be disconnected for maintenance.

2) If the battery system needs to be moved or repaired, the power must be cut off and the battery is completely shut down.

3) Do not connect or disconnect power cables when the power is on. Transient contact between the core of the power cable and the conductor will generate electric arcs or sparks, which may cause fire or personal injury.
4) It is prohibited to connect the battery with a different type of battery.
5) It is prohibited to put the batteries working with faulty or incompatible inverter.
6) In case of fire, only dry powder fire extinguisher can be used. Liquid fire extinguishers are prohibited.
7) Please do not open, repair, or disassembly the battery except staff authorized. We do not undertake any consequences or related responsibility which because of violation of safety operation or violating of design, production, and equipment safety standards.
8) Any foreign object is prohibited to insert into any part of the battery.
9) Do not place batteries in water or other liquids.

Warning

10) Wear ESD gloves when handling the equipment. Do not wear clothes prone to static electricity.
11) If the battery is stored for a long time, it is required to charge them every six months, and the SOC (status of Charge) should be no less than 90%.
12) Battery needs to be recharged within 12 hours, after fully discharged.
13) Use only dry cloth to clean the battery. Do not use cleaning solvents.
14) Do not paint any part of the battery, include any internal or external components.

Notice

1.4 Disclaimer

The manufacturer shall not be liable for equipment functional abnormality, component damage, personal safety accident, property loss, or other damage caused by the following reasons:

1) The batteries are not charged as required during storage, resulting in capacity loss or irreversible damage to the batteries.

2) The battery is damaged, falls, or leaks due to improper operations or incorrect connection.

3) Battery parameters are incorrectly set.

4) After being installed and connected to the system, the batteries are not powered on in time, which causes damage to the batteries due to over discharge.

5) The batteries are connected with extra loads or use with other batteries, including but not limited to batteries of other brands or batteries of different rated capacities.

6) The batteries are damaged because exceeding the operating environment (too high or too low) or external power parameters do not meet the technical specifications, for example the power grid is unstable and experiences outages frequently.

7) Batteries are frequently over-discharged or the batteries have not been fully charged for a long time.

8) The warranty period of batteries has expired.

3. Installation

3.1 Installation Environment

Make sure that the installation environment meets the following conditions:

● The area is completely waterproof.
● The floor is flat and level.
● There are no flammable or explosive materials nearby.
● The ambient temperature is within the range of 0 ^ 50 ^ .
● The temperature and humidity are maintained at a constant level.
● There is minimal dust and dirt in the area.

Caution

If the ambient temperature is out of the operating range, the battery module will stop operate to protect itself. The optimal temperature range for the battery module to operate is 0 °C to 50 °C. Frequent exposure to harsh temperatures may deteriorate the performance and shorten the life cycle of the battery module.

3.2 Mounting the Modules

Step 1: Clip two SNAP bushings into the stand feet. Then, fix two fixing plates on the stand feed (both sides) with eight screws. Finally, fix two L-type brackets on the battery module (both sides) with four screws.

    C --> D["Final Packaging"]

Step 2: Install one battery module by following below steps.

(a) Use a 13 mm drill to drill holes about 60 mm deep according to the distance indicated on the below chart. Drill two holes on the

floor first, then drill two holes on the wall. If there is one more battery module to be stacked up, drill two holes at a vertical distance of 420 ~mm .

(b) Push four expansion bolts into the 13 mm holes drilled on the previous step.

(d) Take assembled battery module (in step 1) and put on the ground. Align the hole on fixing plate with the two expansion bolts on the ground. Align the hole on L-type bracket with two expansion bolts on the wall. Pass through the remaining bolt in the floor and wall. Then, screw back the nut, spring washer, and flat washeremove nut, spring washer and flat washer.

Step 3 (If more than one battery module is connected):

For a single battery module connection, please skip this step! If more than one battery module is connected, please follow the instructions below:

(a) Put the additional battery module on the top of battery module installed on the ground. Make sure they are aligned well.
(b) Install one fixing plate to fix two battery modules with four screws as following the picture shown.

Additional Battery Module

(c) Follow the same procedure as step (b) to fix the other side.
(d) Refer to Step 2, fix the top battery module on the wall with two expansion bolts.

3.3 Wiring Configuration

Step 1: Insert the supplied RJ11 jumper into one of the extension ports on the top of the battery module.

Notice

It's required to have RJ11 jumper connected to the single battery module, or to the master battery module when working in parralel with multiple modules for normal operation.

BJ11 Jumper BAT+ BAT- BAT+ BAT-

Step 2 (If multiple battery modules are in parallel):

Insert RJ11 cable to connect the extension port of the master battery module. The other end connects to the extension port of the #2 battery module. If there are more battery modules are connected in the system, repeat this step to connect more battery modules.

Caution

Caution: If more than one battery module is connected for capacity expansion, the battery module that is directly connected to the inverter module is defined as the "master battery module". Make sure that the ID number for the master battery module is set to "0".
