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 place the inverter near a heat source, such as direct sunlight, a fireplace.
•Keep inflammable and explosive dangerous items or flames away from the
inverter.
•Do not soak the inverter in water or expose it to moisture or liquids.
•Do not charge or discharge damaged inverter.
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

- 5 -
cause fatal injury to the operator, third parties, and equipment. The manufacturer
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.

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 of running water and seek
medical advice.
2）Contact with skin: Wash the contacted area with soap 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 and evacuate the
crowd immediately.
Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection design

- 8 -
against any hazard results, rupture of battery shall may still 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 lithium
metal. If the shell is broken, it will come into direct contact with 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 used in energy storage retrofits and is a new type of AC coupled

- 9 -
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 from AS1 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
