1.3 Responses to Emergencies
Event
Description and recommended actions
Leakage
Inhalation: leave the contaminated area right now.
Swallow: induce vomiting.
Contact with eyes: flush eyes with flowing water for 15 minutes.
Contact with skin: wash thoroughly with soap and water.

Safety
5
Immediately seek for medical intervention after taking emergency
measures.
Fire
Battery may catch fire when heated above 150℃. Please implement the
following actions:
1. Extinguish fire before the battery catches fire. ABC or carbon
dioxide extinguisher is recommended.
2. If the fire is too strong to put out, move battery to a safe place
before it catches fire.
3. If battery is on fire, evacuate people first before seeking help from
professional fire protection personnel.
4. If battery catches fire during charging, turn off the breaker
between battery and PCS when safety can be guaranteed.
Wet
battery
If battery became wet or has been submerged in water, do not access it.
Immediately contact your distributor for technical assistance.
Damage
Damaged battery is dangerous and must be handled with utmost care.
They are not usable for use and could pose a safety threat to people or
property. If battery is suspected to be damaged, stop any operation and
return it to distributor.
1.4 Storage safety
Place battery according to signs on packing case. Do not put battery upside
down or sidelong.
Store batteries in a place free from direct sunlight and rain.
Keep batteries at least two meters away from a heat source (such as a radiator).
Avoid contacting with corrosive and organic substances (including gas
exposure).
Batteries with deficiencies should be separated from normal batteries by setting
wall between or placing in difference fire protection zones.
Ambient temperature ranges between -30℃to 60℃during the first seven days,
and ranges between-20℃to 45℃within six months. Relative humidity ranges
between 5%RH-95%RH. Keep the storage area dry, clean and well ventilated.
In case of storage over six months, batteries should be recharged in the
following steps:
1. Identify batteries that need recharging;
2. Ensure batteries in power-off mode. Refer to Quick Guidance to complete
the installation and wire connection;
3. Set “CV=55V，CC=64A” and start recharging;
4. Recharge until LED2 flicks;
5. Leave circuit open and rest batteryfor five minutes. Check battery voltage.
If voltage is not less than 52 V, the recharging succeeds.
1.5 Transportation Safety
Battery has cleared UN38.3 (Section 38.3 of the sixth Revised Edition of the
Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria) and

Safety
6
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.
During transportation, put battery flat, do not have battery stand or lean on
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.
Do not pile up foreign objects on the top of battery. Four batteries at most
can be piled up.
Maintain original packaging and keep labels complete and recognizable.
Prevent from direct sun exposure, rain, condensation and mechanical
damages.

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 64Ah cells in two parallel and sixteen serial connect
(2P16S). Battery coordinates with PV, PCS, Grid and loads in the residential energy storage
system. The four typical application scenarios 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. Two
batteries can be parallel-connected to expand energy and power of energy storage system.
Battery realizes communication with PCS via CAN network port.
The energy produced by PV is
optimized to supply loads. The excess
energy is used to charge battery, then
export to grid.
Battery powers loads at nighttime when
there is no PV. If battery energy is
insufficient, it can supply loads together
with grid.
When grid falls, battery and PV can
power loads.
Battery can be charged by grid. Users are
suggested to store energy from grid to battery
when electricity price is relatively lower.

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 and RS485 network
ports.
Parallel connection: support a maximum of two batteries in parallel connection.
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 45V～60Vvia P+/P- terminals, battery will be activated from off mode to
standby status.
