PRODUCT OVERVIEW
LV-BAT-W5.12Ac has built-in BMS (Battery Management System), which can
manage and monitor cells information including voltage, current and temperature.
Besides that, BMS can balance cells charging to extend cycle life. BMS has
protection functions including over-dis- charge, over-charge, over-current and
high/low temperature; the system can automatically manage charge state,
discharge state and balance state.
Multiple LV-BAT-W5.12Ac can be connected in parallel to expand capacity and
power, 8 LV-BAT-W5.12Ac can be connected in parallel at most.
PRODUCT OVERVIEW
LV-BAT-W5.12Ac is a lithium battery with an operating voltage range between
45.6~56.16V. It is designed for residential energy storage applications and works
together with a 48v battery hybrid inverter. LV-BAT-W5.12Ac is not suitable for
supporting life-sustaining medical devices.
2.1 Brief Introduction
1. Switch ON
For single LV-BAT-W5.12Ac, switch ON rocker switch (near positive/negative
connector), then long press (more than 3 seconds) ON/OFF button on front panel,
LED will flash then battery will operate normally. L1 to L6 shows battery SOC, L7/L8
shows battery status.
For multiple LV-BAT-W5.12Ac in parallel, switch ON rocker switch on all batteries, long
press (more than 3 seconds) ON/OFF button of MASTER battery, LED will flash,
battery system will automatically encode and assign ID to each slave battery, then
battery system will operate normally.

for manufacturer or professional engineer to debug or service.
2. Switch OFF
Press start button of Master PACK more than 3s and then release the button, the
master pack will shut down after all slave packs shut down(Sleep mode) .
For single LV-BAT-W5.12Ac, switch OFF rocker switch (near positive/negative
connector). For multiple LV-BAT-W5.12Ac in parallel, switch OFF rocker switch on
MASTER battery first. Then switch OFF rocker switch on all slave batteries.

3.1 Checking Before Installation
3.1.1 Checking Outer Packing Materials
3.1.2 Checking Deliverables
Packing materials and components may be damaged during transportation.
Therefore, check the outer packing materials before installing the battery.
Checking the surface of packing materials for damage, such as holes and cracks.
If any damage is found, do not unpack the battery and contact the dealer as soon
as possible. You are advised to remove the packing materials within 24 hours
before installing the battery.
After unpacking the battery, check whether deliverables are intact and complete. If
any damage is found or any component is missed, contact the dealer.
The below table shows the components and mechanical parts that should be
delivered.
