4.4.4 Battery Installation Steps
It is recommended that the space between battery packs is more than
300mm.
Steps (for T-BAT H 5.8 or HV11550):
Make sure the wall is strong enough to withstand the weight of battery.
Step 1: Fix the wall brakcet (H or G1) on the wall
· Use the wall bracket as a template to mark the position of the 5 holes
·Drill holes with φ10 driller, make sure the holes are deep enough (at least
50mm) for installing and tightening the expansion bolts (J or I1)
·Install the expansion bolts in the wall, and tighten the screws on the bracket
by using the screw driller.
Step 2: Match the battery with the wall bracket
·Lift the battery to the wall bracket
·Hang the battery over the wall bracket, move the battery close to the wall
and match it on the wall bracket
Step3: Lock the joint between hanging board and wall bracket with M5
combinationscrew (I or H1).

Connecting Charging Cables between Inverter and T-BAT System:
This step is going to connect power cables between inverter and T-BAT system.
The default length of power cables are 2 meters, so customers can appropriately
cut the cable according to the actual installation environment. As a result, each
power cable has one terminal block when leaving the factory, and customers
need to connect the other end of terminal block by themselves.
Cable Connection Steps:
Step2. Insert the stripped cable up to the stop (negative cable for DC plug(-) and
positive cable for DC socket(+) are live). Hold the housing on the screw
connection.
Step3. Press down the spring clamp until it clicks audibly into place (You should be
able to see the ne wie strands in the chamber)

1. Connect all the cables on the left side of T-BAT H 5.8.
2. Run the cables through the corrugated pipe.
3. Do remember to insert the series-connected cable at “-” and “YPLUG” on the
right side of the last battery pack to complete the internal circuit.
4. Set the cables into the groove of metal plates and screw them back to the
battery pack on both sides.

For T-BAT H 5.8 + 1~3 battery packs:
1. Connect the cables at one end of the T-BAT H 5.8/HV11550.
2. Run the cables through the corrugated pipe.
3. Set the cables into the groove of metal plates and screw them back to the
battery packs on both sides.
4. Do remember to insert the series-connected cable at “-” and “YPLUG” on the
right side of the last battery pack to complete the internal circuit.
CAUTION!
One T-BAT system is allowed to install one T-BAT H 5.8 with three
battery packs at most. Connecting more than three battery packs to
the T-BAT system will blow the fuse, and the batteries will be damaged.
Please keep in mind and follow this instruction.

The black-start function is only used in the off-grid environment when there is no
other power supply.
Note: if the battery is started in black-start mode, although there is no BMS
communication, the port still has high voltage and there is a risk of electric
shock!
After the black-start mode is started, if the BMS communication couldn't be built
within 3 minutes , the black-start fails.

NOTE!
When powering on the BMS, the system will start self-testing. If the
buzzer bips, it means DIP conguration fault or communication failue
occurs. If the buzzer bips, please check if the number of battery packs is
corresponding to the DIP conguration, and also check if the RS485
communication cables are correctly connected. After checking above
two situations, press the POWER button to power on, and press the
POWER button again 10s later. In addition: The buzzer will only alarm on
the corresponding fault during the power-on self-test. When the self-
test is completed, it won't bip again even if the same fault occurs.
NOTE!
Frequently pressing the POWER button may cause system error. Please
make sure at least 10 seconds is left before you pressing the POWER
button the second time.

The LED indicators on the front panel of the battery pack are showing the
operating status.

The capacity indicators show the SOC:
·
When the battery pack is neither charging nor discharging, the indicator
lights are off.
When the battery pack is charging, part of the Blue LED is fashing with the
frequency of light on for 0.5s, light offfor 0.5s, and part of the Blue LED keeps
light on. Take SOC 60% for instance, in charging state:
1. The rst wo Blue LED indicators keeps on
2. The third Blue LED indicator ashes once every 1s
When the battery pack is discharging, the Blue LED is ashing with the
frequency of light on for 1s, and light offfor 4s. Take SOC 60% for instance, in
discharging state:
1. The rst three blue LED indicators ash once every 5 seconds

6 Troubleshooting
6.1 Troubleshooting
Check the indicators on the front to determine the state of the T-BAT system. A
warning state is triggered by a condition, for example, when voltage or
temperature is beyond the designed limitations. The T-BAT system's BMS
periodically reports its operating state to the inverter.
When the T-BAT system falls outside prescribed limits, it enters a warning state.
When a warning is reported, the inverter immediately stops operation.
Use the monitoring software on the inverter to identify the cause of the warning.
The possible warning messages are as follows:
BMS_External_Err
The communication
between BMS and
inverter is interrupted
Check if the
communication cable
between BMS and inverter
is correctly and well
connected.
BMS_Internal_Err
1. DIP switch at the
wrong position;
2. The communication
between battery packs
is interrupted
1. Move the DIP switch to
the correct position;
2. Check if the
communication cable
between battery packs is
correctly and well
connected.
BMS_OverVoltage Battery over voltage
BMS_LowerVoltage Battery under voltage
BMS_ChargeOCP Battery charge over

BMS_DishargeOCP Battery discharge over
