5 Product Overview
5.1 Brief Introduction
Product Overview: BETTENERGY POWERBOX-4400LV/6100LV is a Lithium
battery energy storage system with an operating voltage range of between 49V~56.8V, it is
used for household energy storage applications, in cooperation with low voltage inverters
to achieve home energy storage purpose.
The product has a built-in B M S (Battery Management System) which can manage
and monitor cells information, including voltage, current and the temperature. In
addition, the BMS can balances battery charging to extend lifespan. BMS has the
protections including over-discharge, overcharge, over-current, high / low temperature,
etc.
The system can automatically manage the charging state, discharge state and balance
state. Multiple batteries can be connected in parallel to expand storage capacity to meet
larger capacity and longer power supporting duration requirements, and the
BETTENERGY POWERBOX supports up to 16 parallel operation.

The CAN communication terminal (RJ45 port) follows the CAN protocol and
connects to the inverter CAN communication
1. The BMS controls the charging current / charge voltage ordischarge current /
discharge voltage of the inverter, via CAN, based on the battery voltage and
battery temperature.
2. If the battery capacity is less than 8%, the BMS control inverter forces the
charges via CAN communication to avoid damage to the battery due to deep
discharge.
3. If the SOC is below 97% for a consecutive month, the BMS controlsthe
inverter via CAN communication, charging the battery fully to correct the
SOC error.
