Page 9: Brief Introduction
4. BRIEF INTRODUCTION The EG4 48V LL-S rack-mounted Lithium batteries are ideal for low-voltage energy storage system applications. These batteries use lithium iron phosphate cells with the highest safety performance and a battery management system (BMS) that can monitor and collect voltage, current, and temperature of each cell within the module in real time. - Page 10 19-inch cabinet and communicates with external devices via CAN/RS485 as well as with other EG4 batteries via RS485. The modules can be connected in parallel to meet expansion requirements. Inter-battery communications support a maximum of 64 modules for the 6 DIP switch model or 16 modules for the 4 DIP switch model.

Page 12: Emergency Stop (Rsd, Ess Disconnect)
5.2 EMERGENCY STOP (RSD, ESS DISCONNECT) The optional ESS disconnect can be used to shut down all batteries and inverters (if equipped) with the push of a button. This integrated safety feature ties directly into the battery communication system via an open Battery-Com port using a standard Cat 5/6 ethernet cable. -

The state of the battery when placed into storage will affect how long it can be stored as well as the battery’s condition when it is brought out of storage. EG4 recommends that each battery is brought to a 100% SOC (state of charge) before placing it in storage. Lithium batteries will lose a certain percentage of their total charge while in storage, depending on how long they are stored and the conditions they are stored in. -
Page 14: Requirements For Installation
6.2.2 REQUIREMENTS FOR INSTALLATION WARNING: Do not put EG4 LL-S batteries in series! The BMS and internal components are not designed to handle this setup, which could cause the modules to fail leading to damage. • Avoid exposing batteries to conductive materials, such as water, strong oxidizers, and strong acids. -
Page 15: General Installation
Tools Needed for Installation The tools required may vary depending on the mounting location. Typically, the following items are needed to install the battery into an EG4 battery rack solution or general racking: 1. 10mm socket and ratchet 2. Phillips head screwdriver 3. -
Page 16: Installation In Eg4 Battery Rack
WARNING: Do not ground rack/cabinet or door to negative or positive bus bars! In this image, there are 6 EG4 LL-S 48V 100Ah batteries wired in parallel. This battery bank still maintains the appropriate 48V needed for a system. However, the amp hour rating of this bank has increased to 600Ah. -
