⚫It is very important and necessary to read the user manual carefully before installing or using the
battery. Failure to follow any of the instructions or warnings in this document can result in
electrical shock, serious injury, death, or may damage the battery and the whole system.
⚫If the battery is stored for a prolonged time, it is requirement that they are charged every three to
six months, and the SOC should be no less than 80%.
⚫The battery needs to be recharged within 12 hours, after fully discharging.
⚫Do not expose cable outside.
⚫All battery terminals must be disconnected before maintenance.
⚫Do not use cleaning solvents to clean the battery.
⚫Do not expose the battery to flammable or harsh chemicals or vapors.
⚫Do not paint any part of the battery, include any internal or external components.
⚫Do not connect battery with PV solar wiring directly.
⚫Any foreign object is prohibited to be inserted into any part of the battery.
⚫Any warranty claims are excluded for direct or indirect damage due to items above.
1.1.Before Connecting
⚫After unpacking, please check the battery and packing list first, if the battery is damaged or spare
parts are missing, please contact the dealer.
⚫Before installation, be sure to cut off the grid power and make sure the battery is in the turned-off
mode;
⚫Wiring must be correct, do not mix-connect the positive and negative cables, and ensure no short
circuit with the external device;
⚫It is prohibited to connect the battery with AC power directly;
⚫The embedded BMS in the battery is designed for 48VDC, please DO NOT connect battery
in series;
⚫It is prohibited to connect the battery with different type of battery;
⚫Please ensure the electrical parameters of battery system are compatible to inverter;
⚫Keep the battery away from fire or water.
1.2.During operation
⚫If the battery system needs to be moved or repaired, the power must be cut off first and the
battery is completely shut down;
⚫It is prohibited to connect the battery with different type of battery;
⚫It is prohibited to put the batteries working with faulty or incompatible inverter;
⚫In case of fire, only dry powder fire extinguisher can be used, liquid fire extinguishers are
prohibited;
⚫Please do not open, repair or disassemble the battery. We do not undertake any consequences
or related responsibility due to violation of safety operation or violating of design, production and
equipment safety standards.

4.2.Tools
The following tools are required to install the battery pack:
⚫Wire cutter
⚫Crimping Modular Plier
⚫Screw Driver
NOTE
⚫Use properly insulated tools to prevent accidental electric shock or short circuits.

version 3.0 : 2021/7/29 - 11 -www.youth-power.net
⚫If insulated tools are not available, cover the entire exposed metal surfaces of the available
tools, except their tips, with electrical tape.
4.3.Safety Gear
It is recommended to wear the following safety gear when dealing with the battery pack:
⚫Insulated gloves
⚫Safety goggles
⚫Safety shoes
5.Installation
5.1.Inventory of items
Thoroughly inspect the packaging upon receipt of goods.If there is any item missing or if there is any
damage to the external packaging or to the unit itself upon unpacking, please contact us immediately.

version 3.0 : 2021/7/29 - 12 -www.youth-power.net
5.2.Installation Location
Make sure that the installation location meets the following conditions:
⚫The installation site must be suitable for the size and weight of the battery.
⚫Must be installed on a firm surface to sustain the weight of battery.
⚫The area is water proof.
⚫There are no flammable or explosive materials in proximity
⚫The ambient temperature is within the range from 0°C to 45°C.
⚫The temperature and humidity is maintained at a constant level.
⚫There is minimal dust and dirt in the area.
⚫Installation must be vertical or tilted backwards by maximum 15°- avoid forward or sideway
stilt.
CAUTION
If the ambient temperature is outside the operating range, the battery pack stops operating to protect
itself. The optimal temperature range for the battery pack to operate is 0°C to 45°C. Frequent exposure
to harsh temperatures may deteriorate the performance and life of the battery pack.
5.2.1.Minimum clearances
Observe the minimum clearances to walls, other batteries or objects as shown in the diagram and
picture below in order to guarantee sufficient heat dissipation

5.3.Installing the Battery Pack
5.3.1.Mounting to a wall
WARNING
In order to avoid electrical shock or other injury, inspect existing electronic or plumbing installations
before drilling holes.
The battery is heavy, please handle with care to avoid damage to the product or injury to the installer.
1.Choose suitable firm wall with thickness greater than 80mm.
2.Use the mounting frame as a template, mark the hole position.
3.Drill 8 holes according to the hole position, it is ø10 with depth 60mm.
4.Hammer the M8 screws to the above holes, and screw the nut. Note: Do not position screws
flush to the wall - leave 10 to 20 mm exposed.
5.Fix the mounting frame to the 8 screws.
6.Raise the battery a little higher than the mounting frame whilst maintaining the balance of the
battery. Hang the battery on the frame through the match hooks.
WARNING
Falling equipment can cause serious or even fatal injury: never mount the inverter on the bracket unless
you are sure that the mounting frame is firmly mounted on the wall after thorough checking.

version 3.0 : 2021/7/29 - 14 -www.youth-power.net
5.4.Parallel use of battery for 5-10KWH battery
5.4.1.Parallel use of battery ( All off grid solar inverters )
YOUTH POWER wall battery is a smart battery to match all off grid solar inverter ( 48VDC) types. When
the battery needs to be used in parallel, the maximum connection is 15 units, but we recommend 2-4
units according to application. When connecting with off grid 48VDC solar inverters, it does not need
to add Canbus/RS485 communication cables with inverters, if inverter brand factory does not have
Canbus/RS485 port, just plug and play use as lead acid type
Remarks: If just connect 2 batteries, or we can also connect without the combiner box. Just
working with 2 positive and 2 negative cable connectors with the inverter ports directly.
