Page 10: Introduction
Chapter Introduction The EM048063P3S and EM048126P3S series battery modules are designed to be part of a small-scale electric energy storage system (ESS) for two purposes: • Telecommunication system backup • Residential photovoltaic system Inverter or rectifier NOTE Hereafter in this manual, ESS refers to a set consisting of EM048063P3S or EM048126P3S series battery modules. -
Page 11: Features
Introduction 2.1 Features The EM048063P3S and EM048126P3S series battery modules have the following fea- tures: Built-in battery management system (BMS): A battery module’s BMS monitors its operation and prevents the battery from operating outside design limitations. When a battery module enters an abnormal state, the BMS issues an alert and restricts or disables the battery’s operation. -
