1. Safety Precautions

This section describes the safety information that must be observed when working with battery

packs. To prevent any damages, or personal injury, and to ensure the performance of the battery

packs, please read this section carefully and observe the safety precautions at all times.

1.1 Precautions

It is very important and necessary to read the user manual carefully before installing or using

the product. 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, and could damage the battery, or

potentially rendering it inoperable.

If the battery pack is stored for long time, it is required to charge them every six months, and

the SOC should be no less than 90%.

Please recharged the battery pack within 12 hours, after fully discharged.

All the battery pack terminals must be disconnected before any maintenance.

Do not use cleaning solvents to clean battery pack.

Do not expose battery pack to flammable or harsh chemicals, or corrosive gases or liquids.

Do not paint any part of battery pack, include any internal or external components.

Do not expose the battery pack to direct sunlight for extended periods of time.

Do not connect battery pack with PV solar wiring directly.

Do not insert any foreign object into any part of the battery pack.

1.2 Warning

Do not touch the battery pack with wet hands.

Do not crush, drop or puncture the battery pack.

SEPLOS SUTEN-W51.2V 100AH LIFEPO4 BATTERY PACK USER MANUAL www.seplos.com

Always dispose of the battery pack according to local safety regulations.

Store and recharge the battery pack in a manner in accordance with this user manual.

Ensure reliable grounding.

Do not reverse the polarity when installing.

Do not short circuit the terminals, remove all jewelry items that could cause a short circuit before

installation and handling.

Disconnect battery from power or loads, and then power off battery before installation and

maintenance.

The battery packs should be not stacked more than specified numbers.

Continued operation of a damaged battery pack can result in dangerous situation.

2. Introduction

SUTEN-W

SUTEN-W lithium iron phosphate battery pack is a household wall mounted renewable energy

storage battery pack developed and produced by SEPLOS Technology. It is a low-voltage DC battery

system with an operating voltage of 48V, and works with a low voltage inverter to realize the goal

of energy storage for home application.

SUTEN-W battery pack supports parallel connection to expand capacity, which can meet various

capacity requirements. It has built-in battery management system(BMS), which can manage and

monitor the pack and cells information including voltage, current and temperature. What’s more,

BMS can balance cells charging and discharging to extend cycle life.

SEPLOS SUTEN-W51.2V 100AH LIFEPO4 BATTERY PACK USER MANUAL www.seplos.com

2.1 Features

SUTEN-W comes with a LCD display for pack voltage, capacity and temperature monitoring.

The battery cell used inside, is 16 pieces of 3.2V 100Ah aluminum case prismatic cell.

Battery cell is made from lithium iron phosphate (LiFePO4) with safety performance and longer

cycle life.

Special designed plastic cell holder, holding 8 cells in series, and composes a battery module,

and two modules in series, then connected with BMS, composes the wall-mounted type

battery pack.

BMS has over-discharge, over-charge, over-current, high and low temperature warning and

protection functions.

BMS monitors charge and discharge state, and balance current and voltage of each cell.

BMS comes with upper computer system for real-time cell and pack voltage, current,

temperature, and battery status monitoring and recording.

Flexible configuration, max. 15 packs can be connected in parallel for expanding capacity and

power with 8 DIP switches.

Working temperature range is from -10℃~50℃(Charging 0℃~50℃; discharging -10℃~50℃)

with excellent discharge performance and cycle life.

Pre-programmed with multi-protocols, and works with multi-brands of inverters.
