Accessories

Mounting Steps

Wall Mounting:
Step 1: Fix the wall bracket on the wall

• The bracket needs to be removed from the box. Measure it and mark the position of the two holes. The bubble of the spirit level should be centered.
• Drill holes at the depth of at least 2.36 inches/60 mm by a drill.
• Install the expansion screw tubes on the wall, and screw the wall bracket by a torque wrench.

Step 2: Match the box with the wall bracket
Hang the box over the wall bracket, move the box close to it and match it on the wall bracket. Clip the buckle on the back of the box into the threeslots of the back plate accurately. (Torque: 1.0-1.2 N·m)

CAUTION! Ensure that the system is always exposed to ambient air. The system is cooled by natural convection. If the system is entirely or partially covered or shielded, it may cause the system to stop operating.

Overall Installation

Depending on the connection with different battery systems, there are two parallel options, with details as follows

Connect with T-BAT-SYS-HV-3.0

NOTE
The recommended installation distance between the box and the battery group (including slave group and master group) is 11.81-23.62 inches /300-600 mm, and the distance between the modules is 9.84 inches/250.00 mm.
Before installation, please make sure that the wall can bear the weight of the batteries installed. If not, please take the mode of floor installation.

Cable Connection

Connecting Cables to Inverter
Cable connection from the parallel box to the inverter:

NOTE

• It is recommended to protect the cables by using corrugated pipe.
• If you plug the cable into the wrong port, you can insert the power cable disassembling tool into the gap on the side of the joint to unplug the cable easily.
• Please refer to “battery connection” section of the inverter’s user manual/quick installation guide for details about inverter connection.
• If the connector of the T-BAT-SYS-HV-3.0 controller does not match the connector provided with the accessory cable, you can trim the blue connector and replace it with a black connector. The replacement should follow the rule of male-to-male and female-to-female connections. The Installation mode of black connector is as follows:

The wire order of the communication cable is as follows:

1. Orange stripes on white
2. Orange
3. Green stripes on white
4. Blue
5. Blue stripes on white
6. Green
7. Brown stripes on white
8. Brown

Connecting Battery Modules
For BMS Parallel box-Ⅱ G2 + T-BAT H 5.8 + 1/3/5/7 HV11550 battery pack(s)
From BMS Parallel box-Ⅱ G2 to T-BAT-SYS-HV-5.8:

If there is(are) a port(s) that is(are) not wired after wiring is completed, please don’t forget to put the waterproof cap(s) on the port(s).
To form a complete circuit, connect “-” and “YPLUG” with series-connected cable on the right side of the last battery module. Please check T-BAT-SYS- HV-5.8 User Manual/Quick installation guide for detailed tutorial on cable- connecting between T-BAT H 5.8 and HV10230 battery modules.

For BMS Parallel box-Ⅱ G2 + MC0600 + 2/4/6/8 HV10230 battery modules
From BMS Parallel box-Ⅱ G2 to T-BAT-SYS-HV-3.0:

Connecting Communication Cables
There is a protection cover for the RS485 connector. Unscrew the cover and plug one end of the RS485 I communication cable to the RS485 I connector. Tighten the plastic screw nut which is set on the cable with a rotation wrench. The operation is the same as above if connecting to the COM1/BMS connecter.

For T-BAT-SYS-HV-5.8 (RS485 I, BMS): For T-BAT-SYS-HV-3.0 (COM1, BMS):

Connect the communication cable from the parallel box to the COMM/BMS/RS485 I communication port that is on the left side of the battery module.

Connecting the Ground Wire
Remove the M5*10 screw from the bottom of the BMS Parallel box-Ⅱ G2 with a screwdriver, and then screw the groung wire(10 AWG/6 mm) to the corresponding grounding port

Commissioning

Configuring the Box

• The DIP switch is used to configure the communication between battery module(s) and the device. By default, only two groups of batteries can be matched for use.

• The black-start function is only used in an off-grid application and when there is no other power supply. To Black-start, hold down the button for 20 seconds until the soc light starts flashing blue to indicate successful black-start. If the box is started in the black-start mode, remind that even when there is no BMS communication, the port still contains high voltage with risk of electric shock.
  If the BMS communication has still not been established within 3 minutes after starting the black-start mode, it indicates that the black start fails to start.

• After the BMS Parallel box-Ⅱ G2 is powered on, if the indicator lights alternate flashing red and green for more than two minutes, and then change to green flashing with the inverter reporting “Batt_ClusterCommuCount Mis-Match”, please check the communication connection of the second group of BMS Parallel box-Ⅱ G2, as well as the power-on status of T-BAT H 5.8 or MC0600 connected to the second group.

• After the BMS Parallel box-Ⅱ G2 is powered on, if the indicator lights alternate flashing red and green for more than three minutes, and then change to flashing red for one second and off for three seconds, with the inverter reporting “BMS_Internal_Err 1”, it indicates that the corresponding slave at position 1 failed to connect to the communication successfully. According to the error number, please check if the communication line of the slave at the corresponding position is properly connected.

• The BMS Parallel box-II G2 must be connected to two groups of batteries simultaneously in order to function properly, and the number of slaves in both groups must be the same. The second group of BMS Parallel box-II G2 must contains a T-BAT H 5.8 or Mc0600. And the two battery circuits connected to the BMS Parallel box-Ⅱ G2 must be all HV11550 or all HV10230, and it is not allowed to connect one group with HV11550 batteries and the other group with HV10230 batteries.

• It is prohibited to plug or unplug the power line during the operation of the BMS Parallel box-Ⅱ G2.

Commissioning
After all battery modules are installed, please follow the following steps to start the box:

1. Open the waterproof cover board of the box;
2. Move the circuit breaker switch to “ON”;
3. Press the POWER button to start the box;
4. Reinstall the cover board to the box;
5. Turn on the inverter DC switch;
6. After starting the box, please confirm that the waterproof cover board is closed again.

Status Indicators
The LED indicators on the front panel of the BMS and the battery modules indicate the operating status.

Description of the status indicators of BMS is shown as follows:

The capacity indicators show the state of charge (SOC):
When the battery module is neither charging nor discharging, the indicator lights are off.
When the battery module is charging, a part of the blue LED flashes once every 5 seconds, and a part of the blue LED is on. Take SOC 60% for instance, when in charging state:

1. The last two blue LED indicators are on
2. The third blue LED indicators flash once evey 5 seconds When the battery module is discharging, the blue LED indicators flash once every 5 seconds. Take SOC 60% for instance, when in discharging state:

1. The last three blue LED indicators flash once every 5 seconds

Troubleshooting

Check the indicators on the front to determine the state of the box.
A warning state is triggered when a condition, such as voltage or temperature, is beyond design limitations. Box periodically reports its operating state to the inverter.
When the box falls outside the prescribed limits, it enters into a warning state When a warning is reported, the inverter immediately stops its operation.

Use the monitoring software on the inverter to identify what caused the warning.
The possible warning messages are as follows:

Decommissioning

To shut down the system and dismantling the box, please follow the steps below:

• According to the actual situation, please turn off the breaker located between the inverter and the parallel box.
• Press the POWER button to shut down the box.
• Move the circuit breaker switch to the OFF position.
• Ensure that every indicator on the box is off.
• Disconnect the cables between the box and inverter.
• Disconnect the series wiring terminal on the box.
• Disconnect the rest of cables.
• If needed, unmount the box from the wall bracket to remove it from the wall.
