BRIEF INTRODUCTION

The EG4 12V & 24V-LL 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. The BMS also includes a passive balance function and an advanced battery control strategy, which can help improve the battery pack’s performance. The battery includes  dual, on board, fire- extinguishing modules for added safety.

INSTALLATION

5.1 PACKAGING LIST & PLACEMENT
When the product is unpacked, the contents should match those listed below:

5.2 LOCATION SELECTION AND INSTALLATION
5.2.1 STORAGE
There are a few steps you can take to ensure that batteries are stored safely and in a state that will ensure they are not damaged during storage. These are detailed below.

Battery State
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 iron phosphate 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. We recommend recharging the batteries after 8 – 9 months in prolonged storage.

Environmental Factors
The environment you store your EG4 battery in can greatly affect the health of the battery. For best results, the temperature should remain moderate, between 41°F and 68°F (5°C and 20°C). Keep the battery away from locations where it may get wet or locations  with high humidity (>55%). Store the batteries away from combustible materials.

5.2.2 REQUIREMENTS FOR INSTALLATION
WARNING:
Before using batteries, inspect them for signs of damage. Never use damaged or puffy batteries.
Please contact the distributor if a battery is received in this state or experiences this issue.

• Avoid exposing batteries to conductive materials, such as water, strong oxidizers, and strong acids.
• Avoid putting batteries in direct sunlight or on extremely hot surfaces.
• Keep all flammable materials out of the working area.
• Use caution when handling batteries and/or battery-powered devices to avoid damaging the battery casing or connections.

IMPORTANT: Never position the battery upside down or face down!

5.2.3 INSTALLATION

NOTE: This chart applies for a 200A continuous output (one battery). Where ambient temperature is above 86°F (30°C), cable size must be increased according to NEC 310. The 2 AWG cable included in the package is intended only for the connection from the  module to an EG4 battery rack.

DANGER: When adding or removing a battery from any rack, cabinet, or busbar, turn off ALL batteries, and use a voltmeter to confirm there is no voltage present. This will prevent users from encountering live (powered) busbars by accident. Failure to do so  can result in severe injury and/or death.

Tools Needed for Installation

The tools required may vary depending on how you choose to mount your battery. 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. Torque wrench
4. M8-1.25 terminal bolts (included in package)

Connecting Cables to the Battery Terminals and Busbars

1. Identify the positive and negative terminals on the battery. These are labeled and color coded (red for positive, black for negative).
2. Verify you have all hardware to attach the cable properly. Check to ensure the bolt threads fully into the terminal and can be tightened to the proper torque.
3. Connect the cables to your battery terminals by removing the M8 terminal bolts, inserting them through the eyelet of the proper cable, and reseating the bolt into the terminal block to the correct torque.
4. Connect the positive battery cables to your positive busbar by removing the bus bolts, inserting them through the eyelets of the proper cable, and reseating the bolt into the busbar to the proper torque value. Repeat with all negative cables.
5. DO NOT finger tighten the battery terminal bolts. They require a specific torque to ensure they do not loosen during operation. Failure to properly tighten the terminal bolts can result in serious damage and will void the warranty.

5.2.4 INSTALLATION IN EG4 BATTERY RACK

1. Insert the battery into the rack slot, beginning with the top slot and progressing downward. Slide in until the battery is firmly seated in the rack.

2. Follow steps 1-3 in Connecting cables to the battery terminals and busbars from Section 3.2.3 – General Installation.
   Use the included 2 AWG power cable to connect each battery to the busbar.

3. DO NOT finger tighten the battery or busbar terminal bolts. Both require a specific torque [60 in. lbs. (7Nm)] to ensure they do not loosen during operation. Failure to properly tighten the terminal bolts can result in serious damage and will void the  warranty.

4. Clearly identify the location of the system’s positive and negative terminals (red to the positive terminal and black to the negative) to ensure no connection errors. Then connect to the equipment or switch terminals.

Grounding
You can attach a grounding wire from the rack/cabinet to an equipment grounding conductor, then terminate the EGC at a grounding electrode.

WARNING: Do not ground rack/cabinet or door to negative or positive bus bars!

For example, in this image, there are 6 EG4-LL 12V 400Ah batteries wired in parallel. This battery bank still maintains the appropriate 12V needed for a system. However, the Amp hour rating of this bank has increased to 2400Ah. In addition, the potential  output amperage of the rack increases. Size main battery cables appropriately! Refer to an NEC approved ampacity chart for specifications.

6. OPERATION GUIDE
6.1 BATTERY COMMUNICATIONS
Each EG4 battery is designed with you in mind, displaying as much informationas possible in the simplest manner. EG4 Electronics includes the option of connecting the battery to PC software to monitor the module status. This allows you to see and understand  exactly what the battery is doing as well as troubleshoot if problems arise.

When a single battery is used, it will communicate directly with the system via the RS485 or CAN port.

6.1.1 CONNECTING MULTIPLE BATTERIES IN PARALLEL

1. Ensure all battery breakers and BMS are OFF.
2. Set the address code of each battery according to the DIP Switch ID Table (see the DIP Switch ID Table) making sure there are no duplicate addresses.
3. Establish communication between the batteries via the “Battery-Comm” ports starting with the right port on the last battery address and terminating on the left port of the host.
4. The battery with the No. 1 address (referred to as the host) connects tothe system via communication cable using the RS485/CAN interface. See image to the right)
   5. Power on each battery breaker and BMS one at a time beginning with
   the host battery.

6.1.2 DIP SWITCH ID TABLE
EG4-LL batteries interface with an inverter by designating a “Host” battery (DIP switch ID No. 1). The ID code range is 1‒16, and the communication mode can support up to 16 modules in parallel. The battery will connect directly via a battery communications  cable or a standard CAT 5, 5e, or 6 cable (for closed loop communications with non-EG4 inverter types). For Victron communication cables, contact your distributor.

REMINDER: If you have multiple batteries, all DIP switch settings must be different from each other. This allows all equipment to see each battery in the bank separately.

6.5 BATTERY CHARGING
6.5.1 CHARGE CYCLE
Ensure the proper settings are set on the charge controller and/or inverter being used to avoid overcharging or damaging the module. (Refer to the Technical Specifications for a full list of charging/discharging parameters.)

IMPORTANT: It is normal for LFP batteries that have their own internal BMS and that are wired in parallel to demonstrate a wide variety of SOC readings during any given charge or discharge cycle. Variations of up to 10% are common. This is not cause for  concern or indication that the module is providing less than the maximum capacity. This is caused by even slight variations in wiring resistance to each battery, internal resistance, temperature differences, and even variations in each cell. Even a slight variation  causes one battery to take more of the load or charge for a short time. Over the duration of the discharge or charge cycle, this will balance out with the lagging battery then taking the load or charge at the other end of the cycle resulting in recovering the full listed  KWH capacity of the pack. The voltage differences created as batteries diverge in SOC will eventually cause them to converge at some point in the cycle.

TROUBLESHOOTING, MAINTENANCE & DISPOSAL

7.1 INTRODUCTION TO THE BMS
The BMS (Battery Management System) is intended to safeguard the battery and battery cells against a variety of situations that could damage or destroy system components. This protection also aids in keeping the battery and battery cells operational for a  greater number of life cycles. Each EG4-LL battery is specifically configured to ensure peak performance and operation with any system.

7.1.1 BMS PROTECTION

PCB Temperature Protection
The BMS will ensure that the PCB (Printed Circuit Board) does not overheat. This is the part that houses most of the “brains” of the battery. This feature will turn off the battery if it begins to overheat.

Cell Balance Protection
Cell balance ensures that each cell is within a specific voltage range of each other. Cell balance is crucial for ensuring that the battery is operating properly for its lifespan. This is always done automatically.

Environmental Temperature Protection
It may be dangerous to attempt using the battery in extreme heat or cold. Continued operation in these conditions may result in permanent damage to the battery module and its components. To prevent this, the BMS is designed to measure the temperature  while charging/discharging and will shut down the battery to prevent damage.

Voltage Protection
The BMS is designed to continuously monitor the voltage of each individual cell and ensure that they are not over/undercharged.

Current Protection
The BMS is designed to constantly monitor the charge/discharge amperage and has built-in safeguards against exceeding specific parameters. These include built-in timers that shut off quickly in the event of short circuits, extremely high amperage and delayed  shut down for amperage that is only slightly above the maximum capacity.

7.2 TROUBLESHOOTING
7.2.1 ALARM DESCRIPTION AND TROUBLESHOOTING
When the ALM light on the battery control panel is on, it means that the battery has given an alarm or has been protected from potential damage. Please check the cause of the failure through the app or BMS Tools and take appropriate measures or go directly to  the battery site to troubleshoot.
