BATTERY WIRING WARNING Be sure the battery packs are powered "OFF" before making/removing any connections. Use two 2/0 Awg (70mm) outdoor rated positive and negative battery cables (not included) with Hydraulic crimped ring terminals and heat shrink insulation. When paralleling batteries, the battries can be terminated in a combiner box or bussbar rated for the number of inverters being installed. When paralleling batteries, use a communication cable to connect the master battery to slave batteries for battery-to-battery communication. This cable is a standard RJ45 Cat 5 computer cable. 7.1 BATTERY PARALLELING COMMUNICATION WIRING GUIDE 1. Ensure all battery breakers and BMS are OFF. 2. Set up communication between the batteries via the "Battery - Comm" ports of each battery. Use the paralleling kit communication cable to daisy chain all paralleled batteries in the bank together. See diagram below for example. Connected to the inverter Link In CAN Link Out Link In CAN Link Out Link In CAN Link Out 3. If the communication of one battery is connected to the inverter, then that battery is the master unit. 4. Install battery paralleling cables between batteries. Refer to Section 8.2 Battery Cable Connections for battery cable connection diagram examples. 5. Once all cable connections are completed and the system is ready to be commissioned, power on each battery breaker and BMS ON/OFF switch one at a time beginning with the master battery. Battery automatically assigns addresses. No dip switch programing required. 7.2 BATTERY WIRING DIAGRAM AND GUIDE The following battery wiring diagrams are examples using the external busbars to parallel the batteries together and connect the inverter(s) to the batteries. Systems with more batteries than these configurations require the use of an external fused positive busbar and an unfused negative busbar rated at a minimum of 210A per battery. Each fuse should be a maximum of 250 A. Alternatively, larger systems could rely on the MN15-12KW-AIO ability to draw from different battery packs while still paralleling inverters rather than utilizing external busbars. The maximum recommended number of paralleled MN15-12KW-AIO inverters is 9. If this approach is used, we recommend a ratio of 2 batteries per pack controlled by each MN15-12KW-AIO inverter. Separating packs is only recommended if each pack's average SOC is monitored over time and does not diverge by more than 10%.Refer to NEC code and the local AHJ for exact requirements. If installing one MN15-12KW-AIO inverter and one MNPowerFlo 16 battery, you must use a pair of 4/0 copper battery cables if not using a bussbar. NOTE:In the following diagrams, units are spaced 12 in. apart. Local regulations may require a larger minimum battery spacing. Check with the local AHJ for these requirements. Single battery install must use 4/0 AWG Copper Battery cable Pro Tip:One MN15-12KW-AIO MNPowerflo 16 and a minimum of 2 WallMount units is the recommended configuration to maximize the system's functionality.

POWER Notes Maintain Safety: When operating electrical equipment, Use appropriate safety measures, such as wearing insulated gloves and ensuring hands are dry. Regular Maintenance: Check and maintain the energy storage system to ensure its long-term stable operation. 7.6 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 with internal BMS and that are wired in parallel to demonstrate a variety of SOC readings during charge or discharge cycles. bold txt. 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 8.1 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 MNPowerflo 16 battery is specifically configured to ensure peak performance and operation with any inverter system. 8.2 BMS PROTECTION PCB temperature protection The BMS will ensure that the Printed Circuit Board (PCB) does not overheat. This is the component 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. 8.3 TROUBLESHOOTING Alarm Description and Troubleshooting. When the Alarm light on the battery control panel is on, it means that the battery has given an alarm or has been protected from potential damage. FRONT PANEL INDICATOR LIGHTS Run/Alarm LIGHTS The MNPowerflo16 battery features 2 LED status indicator lights on the front panel of the unit.

There are a few steps that can be taken to ensure that batteries are stored safely and in a state that will ensure they are not damaged during storage. The steps 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. MidNite 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. We recommend recharging the batteries after 8 9 months in prolonged storage. Environmental Factors The environment the battery is stored in can greatly affect the health of the battery. For best results, the temperature should range between 33°F and 90°F (0.6°C and 32°C). Mount the battery in a location where it is not exposed to direct rain, standing water and ensure the battery is mounted on non combustible material. Keep the battery away from direct sunlight. Store the batteries away from combustible materials.
