Packing List (Battery Module)

Installation Prerequisites

Before installation, make sure that the installation site meets the following conditions:

• The building can stand up to earthquakes;
• The site shall be over 0.62 miles away from the sea, to avoid damage caused by salt water and humidity;
• The floor shall be flat; · No inflammable and explosive goods are placed within at least of 3 ft;
• The ambiance shall be shady and cool, away from heat sources and direct sunlight;
• The temperature and humidity remain at a constant level;
• The installation site requires less dust and dirt;
• There are no corrosive gases, including ammonia and acid vapor; and
• The same generation products are recommended to give priority to use.
  In practice, the requirements of battery installation may be different due to environment and locations. In that case, follow up the exact requirements of the local laws and standards.

Note!
The Triple Power battery module is rated at IP65 and thus can be installed outdoors as well as indoors. However, if installed outdoors, the battery pack shall not be exposed to direct sunlight and moisture.
Note!
If the ambient temperature exceeds the operating range, the battery pack will stop running to protect itself. The optimal temperature range for operation is 59/15 to 86/30. Frequent exposure to harsh temperatures may deteriorate its performance and lifetime.
Note!
For the first installation, the interval among manufacture dates of battery modules shall not exceed 3 months.

Installation Steps for BMS 1 + Battery 1

Before installation, please make sure the wall is strong enough to withstand the weight of Battery.

1. Step 1: Locate the Base 193 ± 2 mm away from the wall, and adjust it with a torque wrench to ensure that it is parallel to the ground. A spirit level is required.||
   
   Note: The letter “R” and “F” on the Base respectively indicate Rear and Front. Therefore, the side with “R” shall be against the wall.

2. Step 2: Place a battery module on the base.
   

3. Step 3: Place the Wall Bracket, determine the position of holes, mark it with a pen, remove the Wall Bracket, and then drill the two holes (10 mm).
   Step 4: Place Expansion Bolts into the holes.
   
   Note! The Wall Bracket(s) must be installed to secure the battery module(s) connecting the cover or/and BMS.

4. Step 5: Secure the Wall Bracket to the battery using screws (2 X M510, torque: 2.2-2.5 N·m) and to the wall using Tapping Screws (2 X ST6L55) and Flat Gaskets (2).
   

5. Step 6: Place BMS on the top of the battery module, and secure both left and right sides with M4 screws (2). See figure below.

Note! Don’t forget to screw both left and right sides of batteries installed. The above steps also apply to place 2 batteries. For details, please refer to User Manual.

Installation Steps for BMS 1 + Battery 3

As for the installation steps for “Left: BMS + BAT x 2, Right: BAT x 1”, please refer to the installation steps for “BMS x 1 + Battery x 1”. After finishing the installation of BMS, two bases and three batteries, please follow the steps below to install the Cover.

S tep 1 : Secure supporting brackets using screws (4 X M4*10, torque: 0.8-1.2 N·m).

Step 2: Put the cover on the battery.

Note! The above steps also apply to place 4 battery modules.

Connecting Cables to Inverter

BMS to Inverter: BAT+ to BAT+ (A: 2 m), BAT- to BAT- (B: 2 m), BMS to BMS (D: 2 m)

Cable Connection Steps:
Note!
The connector connecting to inverter from BMS is delivered with the inverter, for details, please refer to the inverter’s User Manual.

Connecting the BMS Communication Cable

To Inverter It is required for the BMS to communicate with the inverter for proper operation.
Note that the BMS communication cable is shielded with steel tubes.
The wire order of the communication cable is the same as the BMS GND BMS communication cable.

Connecting Cables to One Battery Module

**Note!
Regardless of how many battery modules installed, please put a waterproof cap on the communication port of the unconnected port of battery module (see the circle in the following figures in the quick installation guide).
Ensure that both ends of the cables are connected to the correct connector, which are on the right side of the BMS and battery module. BMS and battery module are required to connect ground wire (F: 150 mm).
BMS to Battery1: B+ to B+ (C: 1200 mm) B- to B- (A1: 690 mm) COMM to COM1 (E: 200 mm)**

Connecting Cables to Two Battery Modules

Ground wires are required to be connected. (C1 (450 mm) is used for connecting two battery modules.)

BMS to Battery1: BMS to Battery1: B+ to B+ (C: 1200 mm) B- to B- (A1: 690 mm) COMM to COM1 (E: 200 mm)  B+ to B+ (C: 120 mm); COMM to COM1 (E: 200 mm)

Battery2 to BMS: B- to B(A1: 690 mm)

Connecting Cables to Three Battery Modules

Ground wires are required to be connected. (C2: 1200 mm is used for connecting battery modules.)
BMS to Battery1: B+ to B+ (C: 120 mm); COMM to COM1 (E: 200 mm);
BMS to Battery3: B- to B- (B3: 1.8 m); Get the cables through corrugate pipe.

Commissioning

Once all battery modules are installed, follow these steps to start the system:

1. Open the cover of the BMS;
2. Move the circuit breaker switch to “ON”;
3. Press and hold the POWER button for more than 1s to start the T-BAT system; and
4. Turn on the AC breaker of inverter.

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. 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 one of the batteries is replaced, the SOC of the battery after replacement shall be consistent with those of batteries that have not been replaced, with the maximum difference of between -5% and 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%.
