the Recommendations on the Transport of Dangerous Goods: Manual
of Tests and Criteria) and SN/T 0370.2-2009 (Part 2: Performance Test
of the Rules for the Inspection of packaging for Exporting Dangerous
Goods). The battery is classified as class 9 dangerous goods, and is
subject to land and water transportation. It is mandatory to report to the
airline company and obtain approval before air transport.
＊ Before transportation, press POWER button for two seconds and
five LED lights flicker for three times to power off battery.

＊ The battery is current qualified for land and sea transport. As respect
to air transport, the battery is subject to mandatory certificates.
＊ During transportation, put battery flat, do not have battery stand
on or lean against the floor to avoid possible crash.
＊ Maintain temperature between -20℃ to 45℃ during the
transportation.
＊ Prohibit mixing up with explosive, inflammable or toxic objects.
＊ Use van-type vehicle including container and metallic van-type
vehicle. Platform vehicle and convertible are prohibited.

2. Introduction to Product
2.1 Intended Purpose
The battery is a 6.5kWh LiFePO4 pack. It has a 48V battery module as
the main power supply unit which composed of 32 pieces of 64Ah cells
in two parallel and sixteen serial connect (2P16S). Battery coordinates
with PV, PCS, Grid, DC Breaker and loads in the residential energy
storage system. The four typical application scenarios are as shown
Battery powers loads at nighttime
when there is no PV. If battery
energy is insufficient, it can
supply loads together with grid.
Battery can be charged by grid.
Users are suggested to store
energy from grid to battery when
electricity price is relatively lower.
＊ Power-off triggered by fault: battery powers off if level three
under voltage, 0V cell or parallel connection failure happens.
＊ Forced power-off: when battery does not connect to mains
supply, press POWER button for two seconds and battery
powers off.
＊ Activation: input 48V-57.6V/2S-5S via P+/P- terminals, battery will
be activated from off mode to standby status.
2.3 Appearance
The battery is an energy storage unit composed of cells, mechanical
parts, battery management system (BMS) as well as power and signal
terminals. Product dimension (unit: mm) and appearance are as
shown below:
2.2 Function
Compared with normal batteries, the battery is characterized with
better charging and discharging performance, longer cycle life and
less self-discharging loss. The build-in BMS can monitor battery
operation status and alarm timely to avoid operation out of limit. A
maximum of 8 batteries can be parallel-connected to expand energy
and power of energy storage system. Battery realizes communication
with PCS via CAN or RS485 network port.
＊ Monitoring: detect the voltage and temperature of cell, the
voltage and current of battery.
＊ SOC estimate: indicate the precise volume of remaining
electricity.
＊ Alarm: alarm when overvoltage, under voltage, overcurrent,
over temperature or under temperature occurs.
＊ Protection: protect against over voltage, under voltage, over
current, over temperature, under temperature, cell fault and
hardware failure.
＊ Report: report alarm messages and operation data to PCS via
CAN or RS485 network ports.
＊ Parallel connection: support a maximum of 8 batteries in
parallel connection.
The energy produced by PV is
optimized to supply loads. The
excess energy is used to charge
battery, then export to grid.
When grid falls, battery and PV
can power loads.
Each battery shall be equipped with an two-pole DC breaker as:
Rated Voltage≥120Vdc Rated Current≥150A
Cut-off current: 2200A
!
CAUTION
Breakers are provided by your system supplier.
The quantity of breakers must be consistent with that of the battries.

A manually operating breaker should be installed between battery and
PCS to control the main circuit during installation, wire connection and
maintenance. The breaker can be operated manually without using any
tool and should be located near the battery. The distance between battery
and the breaker should comply with local regulations. Each battery shall
be equipped with a two-pole DC breaker.
!WARNING
5 Installation Steps under Parallel Connection
Step 1 Install battery.
If voltage difference is measured more than 1V, the difference shall be
adjusted to be less than 1V either by charging the battery with lower
voltage or discharging the battery with higher voltage before conducting
the parallel-connected installation. If two or more batteries are connected
in parallel, the same quantity of two-pole DC breakers are required
between batteries and the inverter.
Step 3 Insert power cables into battery terminals.
Power on batteries in condition of no load, measure their voltages with a
multi-meter and confirm the voltage difference not more than 0.5V. After
that, power off batteries and install them according to the procedures
specified in Section 3.3.
!WARNING
Make the power cables of batteries based on Section 4.2 Step 2. Plug one
end of positive and negative terminals into DC breaker. Respectively
measure the positive and negative terminal blocks of each battery with
a multi-meter, and ensure the voltage outputs under off mode are all
0V. After that, plug the other end of power cables into battery terminals.
Connect DC Breakers with PCS.
Step 2:
Fasten ground terminal and grounding
cable with M6 screw for two batteries.

and technicians must go through technical training and obtain
certificates in compliance with local laws and regulations.
Please stand on dry insulating objects and do not wear metal objects
such as watches, rings and necklaces during operation. Insulating
tools should be used.
Do not contact with two charged positions with a potential difference.
If other people are not allowed to operate, the prohibition sign
should be hung on the distribution equipment: "No closing,
