2. Safety Precautions
Reminding
1) It is important and necessary to read the user manual carefully before
installing or using battery. Failure to do so or to follow any of the
instructions or warnings in this document can result in electrical shock,
serious injury, or death, or can damage battery, potentially rendering it
inoperable.
2) If the battery is stored for long time, it is required to charge every six months,
and the SOC should be no less than 90%
3) Battery needs to be recharged within 12 hours after fully discharged.
4) Do not install the product in outdoor environment, or an environment out
of the operation temperature or humidity range listed in manual.
5) Do not expose cable outside.
6) Do not connect power terminal reversely.
7) All the power terminals must be disconnected for maintenance.
8) Please contact the supplier within 24 hours if there is something abnormal.
9) Do not use cleaning solvents to clean battery.
10) Do not expose battery to flammable or harsh chemicals or vapors.
11) Do not paint any part of battery, include any internal or external
components.
12) Do not connect battery with PV solar wiring directly.
13) Any foreign object is prohibited to insert into any part of battery.
14) The warranty claims are excluded for direct or indirect damage due to items
above.

3) Wiring must be correct, do not mistake the positive and negative cables,
and ensure no short circuit with the external device.
4) It is prohibited to connect the battery and AC power directly.
5) The embedded BMS in the battery is designed for 48VDC, please DO NOT
connect battery in series.
6) Battery must connect to ground and the resistance must be less than 0.1Ω.
7) Please ensured the electrical parameters of battery system are compatible
to related equipment.
8) Keep the battery away from water and fire.
2.2 In Using
1) If the battery system needs to be moved or repaired, the power must be cut
off and the battery is completely shut down.
2) It is prohibited to connect the battery with different type of battery.
3) It is prohibited to connect batteries with faulty or incompatible inverter
4) It is prohibited to disassemble the battery (QC tab removed or damaged).
5) In case of fire, dry powder fire extinguisher or vast amount of water can be
used.
6) Please do not open, repair or disassemble the battery except staffs from
Pylontech or authorized by Pylontech. We do not undertake any consequences
or related responsibility which because of violation of safety operation or

3. Introduction
US5000 lithium iron phosphate battery is the new energy storage products
developed and produced by Pylontech, it can be used to support reliable high
power for various types of equipment and systems.
3.1 Features
1) Build-in soft-start function able to reduce current strike when inverter need
to start from battery.
2) Dual active protection on BMS level.
3) Automatic address setting when connect in multi-group.
4) Support wakeup by 5~12V signal from RJ45 port.
5) Support upgrade battery module from upper controller via CAN or RS485
communication.
6) Enable 95% depth of discharge, available for the inverter which completely
follow Pylontech latest protocol to operate.
7) The module is non-toxic, non-pollution and environmentally friendly.
8) Cathode material is made from LiFePO4 with safety performance and long
cycle life.
9) Battery management system (BMS)has protection functions including
over-discharge, over-charge, over-current and high/low temperature.
10) The system can automatically manage charge and discharge state and
balance voltage of each cell.
11) Flexible configuration, multiple battery modules can be in parallel for
expanding capacity and power.
12) Adopted self-cooling mode rapidly reduced system entire noise.
13) The module has less self-discharge, up to 6 months without charging it on
shelf, no memory effect, excellent performance of shallow charge and
discharge.

6
14) Small size and light weight, standard of 19-inch embedded designed
module is comfortable for installation and maintenance.
15) Compatible with the 48V series battery of Pylontech.
*Mixture using master battery priority:
US5000>UP5000/US3000C/US2000C>U3000/US2000
For same type of module always use the latest production unit as master.
