NOTE!
The Triple Power battery is rated at IP65. Thus, it can be installed outdoors as
well as indoors. However, if the battery is installed outdoors, avoid direct
exposure to the sun and humid air.
NOTE!
If the ambient temperature is beyond the operating range, the battery will
stop operating to protect itself. The optimal temperature range for the
battery to operate is from 15°C to 35°C. Frequent exposure to harsh
temperatures may deteriorate the performance and lifetime of the battery.
NOTE!
When installing the battery for the rst time, the manufacturing date
between battery modules should not exceed 3 months.
4.2 Safety Gear
Installation and maintenance personnel must operate according to
applicable federal, state and local regulations as well as the industry standard.
The product installation personnel shall wear safety gears, etc. in order to
avoid short circuit and personal injury.
4.3 Tools
These tools are required to install the T-BAT system.

4.4 Installation
4.4.1 Check for Transport Damage
Make sure the battery is intact during transportation. If there are any visible
damages, such as cracks, please contact your dealer immediately.
4.4.2 Unpacking
Unpack the battery package by removing the packing tape. Ensure the battery
modules and relevant items are complete. See the package items on section
4.4.3 and check the packing list carefully. If any items are missing, immediately

4.4.4 Battery Installation Steps
There are two installation ways, wall mounting and oor mounting.
I. Wall mounting
It is recommended to keep a distance of 350 mm between two battery packs.
Such a distance must be between 320 mm and 380 mm.
Steps (for T-BAT H 5.8 V2 or HV11550 V2):
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.
4. Installation
30<height<300(mm)
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.
Step3: Lock the joint between hanging board and wall bracket with M5
combinationscrew (I or H1).
Note: Keep the distance from installation point to the oor less than 650mm.

4.5.2 Connecting Power Cables to Inverter
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.
Battery Breaker:
Ø
To ensure the safety of users, a non-polar DC MCB must be installed before
connecting inverter.
The battery needs to be securely disconnect before maintenance.

CAUTION!
One T-BAT system is allowed to install one T-BAT H 5.8 V2

3- Matching T-BAT H 5.8 V2 + 3*HV11550 V2
Black-start conguration
Ø
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!

NOTE!
When powering on the BMS, the system will start self-testing. If the
buzzer bips, it means DIP conguration fault or communication failue
occurs. If the buzzer bips, please check if the number of battery packs is
corresponding to the DIP conguration, 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 selftest 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.
After the black-start mode is started, if the BMS communication couldn't be built
within 3 minutes , the black-start fails.

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