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 packs.
Step 1: fix the wall bracket (H or G1) on the wall
ŸUse the wall bracket as a template to mark the position of the 5 holes
ŸDrill holes with φ10drill, make sure the holes are deep enough (at least
50mm) for installing and tightening the expansion bolts (J or I1)
ŸInstall the expansion bolts in the wall, and screw the bracket by using the
wrench.
Step 2: Match the battery with the wall bracket
ŸTransport the battery to the wall bracket
ŸHang the battery over the wall bracket, move the battery close to it, and
match it on the wall bracket
Step3: Lock the joint between hanging board and wall bracket with M5
combinationscrew (I or H1).

This step is going to connect power lines between Inverter and T-BAT system.
The default length of power lines are 2 meters, so customers can appropriately
cut the cable accroding to the actual installation environment. As a result, each
power line 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

CAUTION!
One T-BAT system is allowed to install one T-BAT H 5.8 plus at most three
battery packs. Connecting more than three battery packs will blow the
fuse, and the battery pack will be damaged. Please make sure the
number of battery packs meets the requirement.
4.6 Overview of Installation
The following diagram is a complete T-BAT system installation with T-BAT H 5.8 +
three battery packs.

3- Matching T-BAT H 5.8 + 3*HV11550
The black-start function is only used in the off-grid environment and 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 has still not been
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 configuration fault or communication failure
occurs. If the buzzer bips, please check if the number of battery packs is
corresponding to the DIP configuration, and also check if the RS485
communication calbes are correctly connected. After these two
situation checked OK, 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. After
the self-test is completed, it won't bip again even if the same fault
occurs.
NOTE!
Frequently pressing the POWER button may cause the system error.
Please make sure at least 10 seconds is needed when you are going to
press the POWER button from the last pressing operation.

5.3 Status Indicators
The LED indicators on the front panel of the battery pack are showing the
operating status.
5.3.1 BMS
The capacity indicators show the SOC:
ŸWhen the battery pack is neither charging nor discharging, the indicator
lights off.
ŸWhen the battery pack is charging, part of the Blue LED is flashing 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 first two Blue LED indicators keeps on
2. The third Blue LED indicator flashes once every 1s
ŸWhen the battery pack is discharging, the Blue LED is flashing with the
frequency of light on for 1s, and light off for 4s. Take SOC 60% for instance, in
discharging state:
1. The first three blue LED indicators flash once every 5s
The following table shows the status of BMS.

To shut down the system, follow the steps described below:
1. Turn off the breaker between Inverter and battery pack;
2. Open the upper cover board;
3. Power off the BMS;
4. Turn off the system by moving the circuit breaker switch to the OFF position;
5. Make sure that every indicator on the T-BAT system is off;

S1 and S2 represent independent status indicators. The status of S1 and S2 have
the same meaning for battery pack in the following table.
Note: only when both S1 and S2 are flashing once every 5s in Green LED, it
means the battery system is active.
NOTE!
After powering off the BMS, the LED lights of S1 and S2 will keep
flashing in 20 minutes.

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 when a condition, such as voltage or temperature is
beyond the design 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 what caused 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.
