INTRODUCTION
Thank you for choosing Sunsynk’s energy storage system.
This lithium iron phosphate battery is one of the new energy storage products developed and produced by
SUNSYNK. It can be used to support reliable power for various types of equipment and systems.
This battery is especially suitable for application scenes of high power, limited installation space, restricted
load bearing, and long cycle life.
This battery has a built-in BMS battery management system, which can manage and monitor cell information,
including voltage, current, and temperature. What’s more, BMS can balance cells charging and discharging to
extend cycle life.
Multiple batteries can connect in parallel for larger capacity and longer power-supporting duration require-
ments.
Some main features of this product are:
Convenient: Quick installation, Wall mounted design, comfortable for installation and maintenance in-
cluded.
Safe and reliable: Cathode material is made from LiFePO4 with safety performance and long cycle life.
The module has less self-discharge, up to 6 months without charging it on the shelf, no memory eect,
and excellent deep charge and discharge performance.
Intelligent BMS: It has protection functions including over-discharge, over charge, over-current, and
over-high or low temperature. The system can automatically manage the charge and discharge state and
balance the current and voltage of each cell.
Eco-friendly: The whole module is non-toxic, non-polluting, and environmentally friendly.
Flexible conguration: Multiple battery modules can be in parallel for expanding capacity and power.
Support remote upgrade (Compatible with SUNSYNK inverter).
Wide temperature: IP65 designed, operation temperature range is from -20ºC to 55ºC, support heating.
The production date of the original batteries and newly added batteries should be as close as possible,
within one year is best. If the time dierences of production are too long, the battery capacity deviation
will be large, and the batteries' energy cannot be fully utilised.
Before expansion, please fully charge the original batteries to 100% (keep SOC 100%), and then charge
the batteries that need to be added to SOC 100%. Next, assemble to achieve the purpose of expansion.
The original batteries can be charged using an inverter; The newly added batteries need to be charged
separately with the battery charger.
Please consult relevant technical personnel before expansion. The individual will bear all consequences
caused by personal misoperation, not covered by the Sunsynk warranty.
Sunsynk lithium battery is prohibited to work in Lead-acid Mode. Any failure caused by using a Lead-acid
model is not covered by the Sunsynk warranty.

ProceduresandPrecautionsBeforeConnecting
After unpacking, please, rst check the product and packing list. Please, get in touch with the local retail-
er if some product is damaged or lacks parts.
Before installation, cut o the grid power and ensure the battery is in the turned-o mode.
Wiring must be correct, do not mistake the positive and negative cables, and ensure there is no short
circuit with the external device.
It is prohibited to connect the battery and AC power directly.
The battery system must be well grounded, and the resistance must be less than 1Ω.
Please ensure the electrical parameters of the battery system are compatible with related equipment.
Keep the battery away from water and re.
SafetyPrecautionsWhileUsing
Cut o the power and completely shut down the battery before moving or repairing the battery.
Connecting the SUNSYNK-L3.0 battery with a dierent type of battery is prohibited.
It is forbidden to put the batteries working with faulty or incompatible inverters.
It is not permitted to disassemble the battery.
Liquid re extinguishers are forbidden. In case of re, only dry re extinguishers can be used.
Please do not open, repair, or disassemble the battery except sta from SUNSYNK or authorized by
SUNSYNK. We do not undertake any consequences or related responsibility because of violation of safe-
ty operation or violation of design, production, and equipment safety standards.
