  • Page 24: General Installation

    8. GENERAL INSTALLATION WARNING Be sure your battery packs are powered “OFF” before making/removing any connections. Use the two included sets of 2/0 AWG (70mm) outdoor rated positive and negative battery cables with the outdoor rated connectors. The connectors will “click” when seated properly. Note: To remove the circular connector installed on the battery, first depress the release button on the side of the connector, then slowly pull until the connection is broken.

  • Page 25: Battery Cable Connections

    8.2 BATTERY CABLE CONNECTIONS The following battery cable connection diagrams are examples using the internal busbars to parallel the batteries together and attach the inverter(s) to the batteries. When relying on the internal integrated busbars, up to 3 batteries are supported in parallel when connected to a single inverter or 4 batteries in parallel when connected to 2 inverters, or up to 5 batteries in parallel when connected to 3 inverters.

    9. 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. When paralleling multiple batteries, the ESS disconnect only needs to have connections made with the master battery.

  • Page 30: Battery Communications

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

    10.2 LCD SCREEN Each module has a built-in HD LCD touch screen used to display important information about the cells including voltage, current, temperature, SOC, among others. Button Description There are 4 function buttons below the display with detailed descriptions, as shown in the table below.

  • Page 32: Communication Protocol Selection

    10.3 COMMUNICATION PROTOCOL SELECTION IMPORTANT: Only the master battery (Address 1) should to be set to the inverter protocol; all other batteries must have unique addresses starting at address 2 and ascending in chronological order. You must connect the CAN/RS485 port of the master battery to your inverter’s (or communication devices) BMS communication port.

    12. BATTERY CHARGING 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 Section 1: Technical Specifications Table 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.

    This protection also aids in keeping the battery and battery cells operational for a greater number of life cycles. Each EG4 battery is specifically configured to ensure peak performance and operation with any system.

  • Page 40: Troubleshooting

    13.3 TROUBLESHOOTING 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.
  • Page 41 Other common faults and solutions NOTE: If any of the warnings or faults from both tables persist, please contact the distributor for additional troubleshooting steps. Fault Analysis Action Check communication port Input proper “host” battery DIP Inverter communication connection, and battery ID switch address, and power cycle failure setting.

  • Page 42: Battery End Of Life

    There are several websites and organizations that will accept this battery to recycle at little to no cost to the user. At EG4, we understand that we are working with customers across the United States and the world. Our recommendation is to go online and search the term “Lithium Battery Disposal Near Me.”...

  • Page 43: Storage

    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.
