Chapter 1 Safety Precautions
This user manual describes the instructions and procedures for the
installation of the TSOL-ACU3.0K AC Coupled Unit. Please read the
user manual before operating it.
Keep this user manual properly and operate strictly according to all
safety tips and operation instructions in this manual.
1.1 Safety Tips
Danger
• Electric shock and high voltage.
• Do not touch live components, as this may result in burns or
death.
• To prevent electric shock during installation and maintenance,
make sure that the AC and DC ports are disconnected.
• When the casing is wet, do not touch the casing of the inverter,
which may present a risk of electric shock.
• Before opening the case, the machine must be disconnected
from the grid and battery; disconnect the power supply for at
least five minutes for the capacitor to fully discharge before
opening the case.
Warning
• Installation, repair, recycling, and disposal of ACU must be
performed by qualified personnel in accordance with
national and local standards and regulations.
• Any behavior to change the functionality of the product

- 3 -
without permission will cause fatal injury to the operator,
third parties, and equipment. TSUNESS is not responsible
for these losses and warranty claims.
• To ensure property and personal safety, the battery modules
and inverter shall be well grounded.
Caution
• Do not modify or tamper with ACU and other components
of the system.
• Please pay attention to the risks caused by improper
modification.
Notice
• This device has a built-in lithium battery and a dedicated
extended battery. Do not extend other brands of batteries at
the battery port.
• ACU outputs AC power directly to the utility grid side and
the backup loads side. Do not reverse output of the two AC
terminals of the inverter.

Chapter 2 Product Introduction
2.1 Scope of application
ACU series is used in energy storage retrofits and is a new type of AC
coupled energy storage system. The built-in lithium battery inside ACU
can be expanded in capacity according to user demands, and the modular
design of the slave device makes it easy to install wiring.
In daytime, solar power supports the loads first while the surplus power
will be stored by ACU, to improve self-consumption rate.
In peak power price hours, power from ACU supports the loads; while
in valley power price hours, ACU is charged by the grid. Finally, a
balance could be realized. In case of grid fault, ACU will make sure no
outage in the loads, achieving UPS function

Chapter 3 Installation Instructions
3.1 Safety Tips
Danger
• Potential fires and electric shocks that are life threatening.
• Do not place any flammable or explosive materials beside
ACU.
• Equipment connected to high-voltage power generation
equipment must be performed by qualified personnel in
compliance with national and local standards and regulations.
Notice
• The pollution level applicable to ACU is Class II.
• Inappropriate or inconsistent installation environment can
shorten the life of ACU.
• Do not install ACU directly by exposing it under strong
sunlight.
• Please do not install in damp places.
• The installation location must be well ventilated.
• TSOL-ACU3.0K (hereinafter also referred to as the master
device) can be used independently. If the battery capacity
needs to be expanded, please use TSOL-B100E-S (slave
device), and maximum 3 slave devices can be accessed.

3.3 Installation steps
3.3.1 Determine the mounting hole position of the hanging panel
The ACU series is mounted on a hanging panel. The mounting
position is determined according to the position of the hanging hole
on the hanging panel. Unit: mm.

Before installation, please make sure that the wall has sufficient
strength to fix the screws and bear the weight of ACU. Mark the
hanging hole position of the hanging panel on the wall and drill the
corresponding hole position; then use a rubber hammer to drive the
screw fixing seat into the hole.

- 13 -
TSOL-ACU3.0K is the master device and TSOL-B100E-S is the
slave device. In order to ensure normal installation of both, the
installation distance between the master and the slave panel, while that
between the slave panels shall at least meet requirements as follows:
Fig. 3.9 Distance between hanging panels

- 14 -
Fix the hanging panel with hex head screw on the installation
position.
Fig. 3.10 Fixing the hanging panel
Please pay attention when installing the device. Please install the
slave device first and then install the master device. In case the distance
between the master device and the slave device is not enough,
installation can’t be done. Carefully attach the device to the hanging
panel and make sure the bottom of the device fits snugly with the panel.
