Product 1: 5KWh Wall-Mounted Lithium Iron Phosphate Home Energy Storage System I. Product Overview This product is a 5KWh wall-mounted home energy storage system, using a 51.2V 100Ah lithium iron phosphate (LiFePO₄) battery pack with a total storage capacity of 5.12KWh. The system integrates the battery, intelligent BMS, and monitoring display unit, directly working in conjunction with a home photovoltaic system. The wall-mounted design saves space and has a simple and aesthetically pleasing appearance. This capacity is a standard choice for entry-level home energy storage, suitable for families with low daily electricity consumption or as a basic backup power source. It can meet the comprehensive needs of regional electricity price fluctuations, arbitrage between electricity and solar power, and prevention of grid outages. It is suitable for basic loads in small apartments, critical load backups in villas, and other scenarios, effectively ensuring the safety and stable operation of home electricity. Applicable Areas: Home solar self-consumption energy storage, photovoltaic surplus electricity storage, peak-valley electricity arbitrage, emergency backup power during power outages, and critical load power supply for small apartments and villas. II. Key Selling Points 1. Flexible Solar Power Integration for Maximum Self-Consumption: Distributed solar power is rapidly growing in many parts of South America (especially Brazil), but electricity consumption is low during peak solar power generation periods at midday, resulting in low grid connection prices for surplus electricity. This system can store surplus solar power generated during the day for use at night or during peak electricity consumption periods, increasing the self-consumption rate of solar power by more than 50% and significantly reducing the need to purchase electricity from the grid. 2. Addressing Grid Instability and Eliminating Power Outages: The power grid in some parts of South America remains unstable, with the curtailment rate in the northeast reaching as high as 21%. This system can automatically switch to energy storage power supply mode within milliseconds when the grid power is interrupted, continuously supplying power to critical loads such as lighting, routers, refrigerators, and security systems for approximately 3-6 hours, comprehensively mitigating power quality issues such as frequent power outages and voltage fluctuations. 3. Arbitrage Between White and Black Electricity Prices to Reduce Electricity Costs: Countries like Brazil have implemented time-of-use pricing policies for white electricity (Tarifa Branca), where peak-hour electricity prices are 2-3 times higher than off-peak prices. The system supports a timed charging and discharging strategy—automatically charging during off-peak hours when electricity prices are low (usually at night or in the early morning), and releasing the stored energy for household use during peak hours or evening rush hours when electricity prices are high, saving users hundreds or even thousands of dollars in electricity bills annually. 4. Lithium iron phosphate cells: safe and stable. Utilizing Grade A lithium iron phosphate (LiFePO₄) square aluminum-cased cells, its thermal stability far exceeds that of ordinary ternary lithium batteries; it will not catch fire or explode even after puncture or compression. The lithium iron phosphate chemistry system has been thoroughly verified, making it the safest choice for home energy storage, giving your family peace of mind. 5. Built-in intelligent BMS: a comprehensive cell management system. It includes a high-precision intelligent BMS that monitors the voltage, current, and temperature of each cell string in real time, providing multiple safety protections such as overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and over-temperature protection. It also features passive balancing (which can be upgraded to active balancing as needed), effectively extending the battery pack's cycle life. 6. Wall-mounted ultra-thin body, installation unrestricted: The entire unit features a wall-mounted ultra-thin design with a simple and modern appearance. The optimized thickness perfectly adapts to the diverse installation space limitations common in South American apartments and townhouses. It can be concealed in garages, equipment rooms, balconies, or interior walls, saving valuable space and matching various modern home décor styles, achieving "invisible energy storage." 7. IP65/IP67 high protection rating (optional): The casing is made of high-strength flame-retardant material, achieving an IP65 or IP67 protection rating. It possesses excellent dust and moisture resistance, resisting rain and sandstorms during outdoor installation. Whether installed on an outdoor wall or in a semi-open space, it ensures continuous and stable operation of the internal circuitry and battery cells under harsh weather conditions. 8. Bluetooth/RS485/CAN multi-protocol communication system: A standard Bluetooth module is included, allowing users to view battery status at any time via a mobile app—real-time voltage, charging/discharging current, remaining power (SOC), internal temperature, cycle count, and other data are readily available. It can also be equipped with RS485 or CAN communication interfaces for seamless integration with inverters or EMS energy management systems, enabling deep integration management and remote monitoring. 9. Modular Parallel Expansion, Seamless Growth: When user electricity demand increases, this system supports parallel expansion of up to 4-16 units of the same model. Initially, a 5kWh capacity can be used as a starting point, with subsequent direct parallel connections of a second or even a third unit. It's plug-and-play, and the BMS automatically coordinates the charging and discharging strategies between units, allowing users to gradually expand capacity with a very low initial investment threshold, offering significant investment flexibility. 10. Flexible and Comprehensive Charging Compatibility: The system is compatible with various charging methods such as photovoltaic, mains power, and wind power. It can be directly charged through the battery interface of the photovoltaic inverter, supplemented with mains power during off-peak hours, or connected to a small wind turbine as backup energy. No matter the user's scenario or energy conditions, a suitable charging solution can be found. 11. 5-Year Warranty, Ample Inventory of Main Models: A 5-year manufacturer's warranty is provided, with stable inventory of main models in local distribution channels and overseas warehouses. Most orders in South America can be shipped quickly and supported on-site, significantly reducing installation and project delivery timelines. III.
