Chapter 1 Safety Precautions
This user manual describes the instructions and procedures for the
installation of the AS1 AC 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 expose the inverter to temperatures in excess of 45°C.
•Do not subject the inverter to any strong force.
•Do not touch uninsulated cable termination.
•Do not soak the inverter in water or expose it to moisture environment.
•
Do not touch the case of the inverter when it is wet in case of electric
shock.
•Do not dispose of batteries in fire. The batteries may explode!
•Do not place the inverter near a
heat source, such as direct sunlight, a
fireplace.

- 5 -
•Keep inflammable and explosive dangerous items or flames away from
the inverter.
•Do not charge or discharge damaged inverter.
•Before performing any work on the inverter or battery pack, please
disconnec
t the inverter from all voltage sources as described in this
document.
Warning
•Installation, repair, recycling, and disposal of AS1 must be performed by
qualified personnel in accordance with national and local standards and
regulations.
•To ensure property and personal safety, the battery modules and inverter
shall be well grounded.
•Risks of chemical burn electrolyte or toxic gases.
•Do not place heavy objects on the top of the system.
•Do not connect any un-dedicated battery pack to the AS1 /B1.
•If the moisture penetrates the system (e.g. due to casing damage), please
do not install or operate the system.
•Do not use wet hands to touch the system.
•Any behavior to change the functionality of the product without permission
will cause fatal injury to the operator, third parties, and equipment. SAJ is

- 6 -
not responsible for these losses and warranty claims.
Caution
•Do not modify or tamper with AS1 and other components of the system.
•Risk of injury by hoisting or falling system
•Inverters and batteries are heavy and personal injury can be caused if the
inverter or battery is improperly lifted or dropped during transport or
improper operation when attached or removed from walls. Lifting and
moved the products shall be conducted by more than 1 person.
Notice
•This device contains a built-
in lithium battery and a dedicated extended
battery. Do not extend the battery pack with other brand battery
at the
battery port.
•AS1 outputs AC power directly to the utility grid and the backup loads
. Do
not reverse the output of the two AC terminals of the inverter.

Dangerous electrical voltage
The device is directly connected to public grid, thus all work
to the battery shall only be carried out by qualified
personnel.

This device SHALL NOT be disposed of in residential waste
Please go to Chapter 8 “Recycling and Disposal” for proper
treatment.
CE Mark
The device is in compliance with Low Voltage Detective and
Electromagnetic Compatibility.

1.3 Emergency situation
Despite of its careful and professional protection design against any
hazard results, damage of the battery may still occur. If a small
amount of battery electrolyte is released due to a serious damage of
the outer casing; or if the battery explodes due to not being treated
timely after a fire breaks out nearby, and leaks out poisonous gases
such as carbon monoxide, carbon dioxide and etc., the following
actions are recommended:
1）Eye contact: Rinse eyes with a large amount ofrunning water
and seek medical advice.
2）Contact with skin: Wash the contacted area with soap

- 9 -
thoroughly and seek medical advice.
3）Inhalation: If you feel discomfort, dizziness or vomiting, seek
medical advice immediately.
4）Use a FM-200 or Carbon Dioxide (CO2) fire extinguishers to
extinguish the fire if there is a fire in the area where the battery pack
is installed. Wear a gas mask and avoid inhaling toxic gases and
harmful substances produced by the fire.
5）Use an ABC fire extinguisher, if the fire is not caused by
battery and not spread to it yet.
Warning
•If a fire has just occurred, try to disconnect the battery circuit breaker and
cut off the power supply first, but only if you can do so without endangering
yourself.
•If the battery is on fire, do not attempt to extinguish the fire but
evacuate
the crowd immediately.
Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection
design against any hazard results, rupture of battery shall may still

- 10 -
occur due to mechanical damage, internal pressure and etc., and
may result in a leakage of battery electrolyte. The electrolyte is
corrosive and flammable. When there is fire, the toxic gases
produced will cause skin and eyes irritation, and discomfort after
inhalation. Therefore:
1) Do not open damaged batteries;
2) Do not damage the battery again (shock, fall, trample, etc.);
3) Keep damaged batteries away from water (except to prevent an
energy storage system from catching fire);
4) Do not expose the damaged battery to the sun to prevent internal
heating of the battery.
Electrical hazard: The reason of fire and explosion accidents in
lithium batteries is battery explosion. Here are the main factors of
battery explosion:
1) Short circuit of battery. Short circuit will generate high heat inside
battery, resulting in partial electrolyte gasification, which will
stretches the battery shell. The temperature reaching ignition point
of internal material will lead to explosive combustion.
2) Overcharge of battery. Overcharge of battery may precipitate

- 11 -
lithium metal. If the shell is broken, it willcome into direct contactwith
the air, resulting in combustion. The electrolyte will be ignited at the
same time, resulting in strong flame, rapid expansion of gas and
explosion.

Chapter 2 Product Introduction
2.1 Scope of application
AS1 series is designed for energy storage retrofits and is an
innovative 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. The AS1 series includes AS1-3KS-5.1, AS1-
3KS-10.2, AS1-3KS-15.3 and AS1-3KS-20.4 models.
In daytime, electricity generated by photovoltaic system will be
supplied to loads first, the surplus energy will charge battery then the
excess electricity will be exported to the grid to improve self-
consumption rate.
At valley power price hours, AS1 can be charged by grid power and
can be called on at peak power price hours to support household
loads. In case of grid fault, AS1 will make sure no outage in the load,
achieving UPS function.
The AS1-3KS-5.1 (herein after refers to AS1) can be used
independently or combined with a dedicated battery pack (Model:
B1-5.1-48, hereinafter refers to the B1) to enlarge the battery
capacity. One to three units of B1 can be connected to the AS1 (three
units at most).
