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.
Page 5: Overview
3 Overview 3.1 Product Description The GW51.2V100Ah product use lithium iron phosphate (LFP) as the positive electrode material. It can be widely used in energy storage systems such as residen- tial energy storage, back-up power, and PV self-consumption optimization. The battery pack is composed of 16 cells of LFP batteries in series connection, with low self-discharge, high energy density, and no memory effect.
Page 6: Application Scenario
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. 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.
Page 7: Application Description
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 to communicate, pay attention to the DIP switch settings.
Page 8: Application Of Nearing The Ocean
4 Application Description 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. 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.
