Warning Indicates a hazard with a moderate risk that may cause death or serious injury if not avoided. NOTE Notice Indicates a hazard with a low level of risk that may cause minor or moderate harm if not avoided. Explanation Supplementary explanation of key information in the main text. "Explanation" is not safety warning information, and does not involve personal, equipment and environmental damage information. 2 Safety 2.1 Safety Precautions Before carrying out battery work, you must read carefully the safety precautions and master the correct installation and connection methods of the battery. Prohibit to turn it upside down, tilt, or collide. Prohibit to short-circuit the positive and negative poles of the battery, otherwise it will cause the battery to be damaged. Prohibit to throw the battery pack into a fire source. Prohibit to modify the battery, and it is strictly prohibited to immerse the battery in water or other liquids. DO NOT place installation tools on the battery during battery installation. DO NOT disassemble, squeeze, bend, deform, puncture, or shred the battery without the authorization of supplier and authorized dealers. DO NOT exceed the temperature range, otherwise it will affect the battery performance and safety. The battery circuit must be kept disconnecting status during installation and maintenance operations. Check the battery connection end bolts regularly to confirm that the bolts are tight. 2.2 Abuse Operation The battery pack needs to avoid abuse operations under the following (including but not limited to) conditions: Abuse Operation Reverse connection of positive and negative poles External short circuit Series connection application Protection Description If the positive and negative poles are connected reversely, the battery will be directly damaged. If the battery pack is short circuited externally, the battery will be directly damaged. The battery pack does not support the application of battery packs in series. If the battery packs are forced to be connected in series, the batteries may be directly damaged, and may even cause fire, explosion and other dangers. 3 Overview 3.1 Product Description The VT48100E ESS series products use lithium iron phosphate (LFP) as the positive electrode material. It can be widely used in energy storage systems such as residential energy storage, back-up power, and PV self-consumption optimization. The battery pack is composed of 15 cells/16 cells of LFP batteries in series connection, with low self-discharge, high energy density, and no memory effect. This type of battery also has excellent performance in high rate, long cycle life, wide temperature range, and high safety. 3.1.1 Features · High energy density Higher volume ratio energy and weight ratio energy. · Maintenance-free The battery pack is maintenance-free in the process of using, which can save customers' battery operation, maintenance testing costs and reduce the frequency of on-site replacement. · Long cycle life The battery pack life is 3 times long than the ordinary lead-acid batteries. · Excellent temperature characteristics When charging, the battery working temperature can reach 060 (recommended using temperature: +1535). When discharging, the battery working temperature can reach -2060 (recommended using temperature: +1535). 3.1.2 Basic Functions · Monitor The battery system uses a high-performance BMS, it has protection functions such as current, voltage. · Alarm Support abnormal alarms such as overvoltage, under-voltage, overcurrent, short circuit, high and low temperature, battery failure, hardware failure, etc. · Communication Provide dual RJ45 interfaces, upload alarming and status data through the RS485/ CAN communication protocol. 3 Overview · Parallel connection application Support multiple battery packs in parallel, RS485/CAN communication supports up to 6 groups without control unit (or max supports 15 groups with control unit). · Balance function Support the cells balance function. · Extended function Extended SNMP, LCD, anti-theft. 3.2 Application Scenario The battery pack is used to provide backup power, load shifting, peaking shaving and can be used for residential energy storage, solar energy storage and other application scenarios. The normal working operation diagram of the battery pack can be as shown in the figure below. Cloud MP DC AC Communication PV Hybrid Inverter Smart Meter Power Grid Battery Important Load Normal Load Figure 3-1 Normal Working Operation Diagram of the Battery Pack 4 Application Description 4.1 Parallel Connection Application The battery packs support parallel connection, and synchronously increases the backup time or backup power. Confirm the consistency between the battery packs, check the SOC and voltage and turn off the batteries before connecting them in parallel. Multiple battery packs of parallel connection need to use RS485/CAN to communicate, pay attention to the DIP switch settings. 4.2 Low-temperature Application · Low-temperature charging The battery pack does not support direct charging of the battery below 0°C. When the minimum temperature of the battery is below 0°C, the BMS will cut-off the charging circuit and cannot be charged. · Low-temperature discharging The battery pack does not support discharge below -20°C. When the minimum temperature of battery is below -20°C, the BMS will cut-off the discharge circuit and cannot discharge. 4.3 Low Battery-capacity Storage (SOC5%) After the battery pack is power off, there will be BMS static power consumption and self-discharge loss. In actual scenarios, it is necessary to avoid low-battery-power state SOC5% storage. If it is unavoidable, the longest storage period is 30 days@25°C, 15 days@45°C. The battery needs to be recharged in time after storage, otherwise the battery may be damaged due to over-discharge, and the entire battery pack needs to be replaced. 4 Application Description The following conditions may cause the battery pack to be stored in a discharged state: After the utility power failure, the line/fault cannot be eliminated in time, and the power supply cannot be restored for a long time. After the installation and commissioning work is completed, the utility power is turned off directly, but the battery pack is not powered off, which will cause the battery to enter the low power consumption mode. Other reasons cause the battery pack to fail to enter low power consumption normally. 4.4 Application of Nearing the Ocean The atmospheric corrosion environment is defined and classified according to the natural environment state, and the A/B environment is defined as follows: A. environment refers to the ocean or the land near the pollution source, or the environment with simple shelter (such as awning. "Near the ocean" refers to the area 0.53.7km away from the ocean; "Near the pollution source" refers to the area within the following radius: 3.7km from the saltwater lake, 3km from heavy pollution sources such as smelters, coal mines, and thermal power plants, chemical industry, rubber, electroplating, etc. 2km from medium pollution sources such as chemical industry, rubber and electroplating, etc. And 1km from light pollution sources such as food, leather and heating boilers, etc. B. environment. Refers to the environment on land or outside with simple shelter (such as awning within 500m from the coast, or the environment on the sea. NOTE The battery pack can be used under other environmental conditions and cannot be used alone under A/B environment. If it is to be used in the A/B environment, it needs to be equipped with a high-protection air-conditioning cabinet, which is recommended to be IP55 or higher. 5 Product Introduction 5.1 Product Appearance Figure 5-1 Appearance Drawing NOTE The battery packs show as above is standard product.
