Chapter 1 Safety Precautions
This user manual describes the instructions and procedures for the
installation of the AS1AC Retrofit Battery System. 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 theAC 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 AS1 must be
performed by qualified personnel in accordance with national and
local standards and regulations.
• Any behavior to change the functionality of the product without
permission will cause fatal injury to the operator, third parties, and

- 4 -
equipment. SAJ 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 AS1 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.
• AS1 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
AS1 series is used in energy storage retrofits and is a new type of AC
coupled energy storage system. The built-in lithium battery inside AS1
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 AS1, to improve self-consumption rate.
In peak power price hours, power fromAS1 supports the loads; while in
valley power price hours, AS1 is charged by the grid. Finally a balance
could be realized. In case of grid fault,AS1 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 AS1.
• 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 AS1 is Class II.
•Inappropriate or inconsistent installation environment can shorten the
life of AS1.
•Do not install AS1 directly by exposing it under strong sunlight.
•Please do not install in damp places.
•The installation location must be well ventilated.
•AS1-3KS-5.1 (hereinafter also referred to as the master device) can be
used independently. If the battery capacity needs to be expanded, please
use B1-5.1-48 (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 AS1 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.

Fig. 3.6 B1-5.1-48 hanging panel dimension (slave device)

- 13 -
Before installation, please make sure that the wall has sufficient
strength to fix the screws and bear the weight ofAS1. 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.
Fig. 3.7 AS1-3KS-5.1 (master device)
Fig. 3.8 B1-5.1-48 hanging panel dimension (slave device)
AS1-3KS-5.1 is the master device and B1-5.1-48 is the slave device. In order to ensure

- 14 -
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

- 15 -
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.
