Getting Started
Unpacking
• This product has been packaged to protect it against transportation damage.
Unpack the battery and lay out the separate components. Keep the original
packaging carton and materials in a safe place. It will help prevent any damage if
the product needs to be transported in the future. In the event that the packaging
materials are to be disposed of, please recycle them where possible.
• Plastic wrapping can be a suffocation hazard for babies and young children, so
ensure all packaging materials are out of their reach and disposed of safely.
• Inspect the home battery for visual damage. Unwind the cords to their full lengths
and inspect them for any damage. Do not use the appliance if the appliance or its
cord have been damaged or are not working properly, or if any parts are missing
(see page 7 for a full list). In case of damage or missing parts, contact our after
sales support centre for advice.
• Make sure you have read and understood all instructions and warnings in this
manual. Refer to the Product Overview, pages 6–8, to familiarise yourself with the
product and identify all parts. Pay particular attention to the safety instructions on
the previous pages.
IMPORTANT!
Installation and wiring must be completed in accordance with local electrical laws
and regulations. This battery MUST be installed by a qualified professional.
WARNING!
• Make sure the main wire is in compliance with the standard of rated capacity
of the battery to avoid hazards like electric shock or fire.
• Do not use the wall receptacle as the input power source for the battery, as
its rated current is less than the battery’s maximum input current. Otherwise
the receptacle may be burned and destroyed.

System Installation
Installation
Diagram of system
This system works through connection with solar panels and the grid. Firstly, your
solar panels generate energy from the sun in the form of DC electricity. This then flows
through an inverter, which converts the DC electricity into AC electricity for use in the
home. Any extra electricity that is not being used is then stored in your 5 kWh Home
Battery/Batteries. Then, when there is no sun, your home can be powered using the
saved energy. This system is also connected to the grid, in case there is no sun and
your battery is depleted, to ensure your home always has access to electricity.
IMPORTANT!
Installation and wiring must be completed in accordance with local electrical laws
and regulations. This battery MUST be installed by a qualified professional.
WARNING!
• Make sure the main wire is in compliance with the standard of rated capacity
of the battery to avoid hazards like electric shock or fire.
• Do not use the wall receptacle as the input power source for the battery, as
its rated current is less than the battery’s maximum input current. Otherwise
the receptacle may be burned and destroyed.

Installation Procedure
WARNING! Make sure the main wire is in compliance with the standard of rated
capacity of battery to avoid hazards like electric shock or fire.
WARNING! Do not use the wall receptacle as the input power source for the battery,
as its rated current is less than the battery’s maximum input current. Otherwise the
receptacle may be burned and destroyed.
• Prior to installation, unpack and check the quantity and appearance of the battery
and parts supplied (see page 9 for more information).
• Select the installation area (see page 11 for more information), ensure it is clear
and that you have the correct tools.
• Place the wall-mounting bracket onto the appropriate area of the wall. Ensure it is
level.
• Using a drill (with a drill bit that is suitable for the type of wall that you are drilling
into), drill 6 M8 bolts (not included) through the holes of the rack and into the wall
(see Fig. 6 for placements).
Installation (Cont.)
• Ensure the bracket is secured to the wall and is sturdy before attempting to hang
the battery from it.
• Lift the battery (CAREFUL! This battery is heavy! Multiple people or specialised
machinery is required) and hook the battery onto the bracket.
• Measure the battery voltage with a multimeter. The general factory voltage of the
battery should be 52-53 V.

• Prior to wiring, check the anode and cathode of the battery. The anode and
cathode terminals should MUST be connected correctly.
• During battery connection, please wear protective gloves. When using metal
tools, such as a as torque wrench, please use insulating packaging so that the
two ends of the metal tools will not make contact with the positive and negative
terminals of the battery at the same time, to avoid a short-circuit.
• Before the battery is connected using the externally connected equipment, make
sure that this equipment has been disconnected. Check whether the connecting
polarity of the battery and total voltage are correct, then connect the battery
anode with the equipment anode and battery cathode with the equipment
cathode and fix the connecting line.
• During movement and installation, the battery must be handled gently. Ensure it
is not dropped or impacted. The battery must not be thrown or beaten to avoid
damaging the battery and creating a potential safety hazard.
• Do not touch the surface of the battery box with the sharp part of any tool to
avoid scratching or damaging the battery box.
• Do not disassemble the battery box without authorization.
• Do not put any article made of metal conductive material together with the battery
or assemble it into the battery box.
Operation Instruction for Installation
Prior to installation, please check whether the battery is functioning normally:
• Press the POWER key at the bottom of the plate for startup. During startup, four
capacity indicator lights on the front panel, the ALM alarm indicator light (red) and
the green RUN running indicator light will illuminate. Check whether all of these
lights illuminate normally.
• After they have illuminated, the ALM alarm indicator light will go out, the RUN
running indicator light will continue to illuminate, and the capacity indicator lights
will illuminate to show the battery’s capacity.
• If the ALM alarm indicator light flashes after startup, it means that the battery has
an alarm. A newly installed battery will seldom have an alarm. The most common
alarm is a battery undervoltage alarm (which results from non-use of the battery
for a long time). This type of alarm will most likely stop after charging the battery
for 30 seconds. If the alarm is still there after this period, please press the reset
key (RST) for 10 seconds, until all LEDs light up to show that the battery has
been reset. If the alarm light is no longer illuminated, the battery may be used as
normal. Otherwise, contact our after sales support team.

Installation (Cont.)
Installation of the lithium battery, wiring and startup;
• Make sure the battery pack is switched off, before installing it onto the wall-
mounting bracket.
• The anode and cathode of the battery pack should be connected to the switching
mode power supply or inverter.
• Please note that the switching mode power supply and inverter should be
disconnected from the AC.
• Press the POWER key on one of battery packs to switch it on. This will activate
any other batteries that are connected in parallel (or you can press the POWER
button of each battery pack successively). The battery will then enter working
mode.
• Lastly, apply AC to the power supply equipment such as switching mode power
supply and inverter to make the whole standby system run.

Recommended Settings
• A lithium battery pack is not as the same as lead-acid battery. Therefore, the
devices that you connect with the battery pack for charging and discharging,
such as inverters, MPPT charger controllers or UPS, must have the pre-settings
below implemented before you start.
Setting AS-5KW-LB2
Max. Charging Voltage 57 V
Floating Charging Voltage 57 V
Max. Charging Current N*(40-10)A
Max. Discharging Current N*(75-10)A
Cut-off Voltage 45 V
Note: “N” represents the number of battery packs connected in parallel.
Battery Management System
When the BMS switch is turned off, the BMS can be put to sleep and the charge and
discharge MOS transistors will be turned off at the same time. Normal operation will
be restored after the BMS is turned back on.
NOTE: Please do not turn on the BMS switch when the product is not in use to avoid
self-consuming the lithium battery.
