PRODUCT OVERVIEW
2.1 Brief Introduction
2.2 Interface Introduction
PRODUCT OVERVIEW GRP5.12-WLV 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.
GRP5.12-WLV is not suitable for supporting life-sustaining medical devices.
GRP5.12-WLV 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-discharge, over-charge, over-current and high/low
temperature; the system can automatically manage charge state, discharge state
and balance state.
Multiple GRP5.12-WLV can be connected in parallel to expand capacity and
power,15 GRP5.12-WLV can be connected in parallel at most.

2.2.1 Switch ON/OFF
1. Switch ON Turn on a single GRP5.12-WLV, turn on the air switch, then press
the circular weak current switch (more than 3 seconds) on / off button, the
LED flashes and the battery works normally. L1 to L6 display the battery
SOC,L7/L8 to indicate the battery status.
For multiple GRP5.12-WLV in parallel, switch ON circular weak current 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
lD to each slave battery, then battery system will operate normally.
04
Press the Circular weak current switch of the master pack for more than 3 seconds and then release the button. When all slave pack are closed, the master pack will be closed (sleep mode). For a single GRP5.12-WLV, turn off the Circular weak current switch. For multiple GRP5.12-WLV in parallel, turn off the Circular weak current switch on the main battery first. Then turn off the Circular weak current switch on all subordinate batteries
