BYD Premium Solar Battery LV FLEX 5.0 kWh

The BYD Battery-Box Premium LV Flex 5.0 kWh is a lithium iron phosphate (LiFePO4, LFP) battery module designed for flexible energy storage in residential, commercial, and bespoke projects. Key Features of the BYD Battery-Box Premium LV Flex 5.0 kWhBattery Chemistry and Safety:Lithium Iron Phosphate (LFP): Cobalt-free, ensuring maximum safety, high thermal stability, and a long lifespan. LFP chemistry reduces the risk of thermal runaway compared to other lithium-ion batteries. Cycle Life: Rated for up to 6,000 cycles at 100% depth of discharge (DOD), offering long-term reliability. Certifications: Meets safety standards including IEC62619, IEC62040, CE, CEC, and UN38.3, ensuring compliance for various markets. Capacity and Scalability:Usable Energy: 5.0 kWh per module, with 100% DOD for maximum usable capacity. Scalable Design: Supports parallel connection of up to 64 modules with a single Battery Management Unit (BMU), enabling systems from 5 kWh to 320 kWh. Modular Flexibility: Allows for easy expansion by adding modules, ideal for growing energy demands in residential or commercial setups. Electrical Specifications:Nominal Voltage: 51.2V, compatible with 48V systems like the Victron Quattro. Operating Voltage Range: 43.2–57.6V, suitable for a wide range of inverter configurations. Max Continuous Output Current: 70A, with a peak output current of 105A for 5 seconds or 200A for 10 seconds (depending on configuration), supporting high inrush loads. Round-Trip Efficiency: ≥95%, ensuring minimal energy loss during charge/discharge cycles. Battery Management System (BMS):Integrated BMS: Features a dual-core, 4-level intelligent BMS for real-time monitoring of battery dynamics, including state of charge, charge/discharge limits, and error codes. Supports continuous operation during upgrades. Communication: Uses CAN or RS485 protocols for seamless integration with leading inverters (e.g., Victron, SMA, Goodwe, Solis, Deye). Requires a BYD Battery-Box Premium LV BMU (sold separately) for inverter communication. One-Button Adaptation: Simplifies setup with automatic configuration for compatible inverters. Remote Monitoring: Supports OTA firmware updates and diagnostics via a dedicated app when connected to the internet. Physical Specifications:Dimensions: 132mm (H) x 482mm (W) x 525mm (D) for a compact 3U rack-mount design, adaptable to standard 19" cabinets. Weight: Approximately 47–48 kg per module. Installation Options: Flexible mounting options include floor-stacking (up to 4 units), rack-mounting, or vertical installation in bespoke enclosures. Protection Rating: IP20, suitable for indoor use. Compatibility:Compatible with market-leading single-phase and three-phase inverters, including Victron (e.g., Quattro, MultiPlus), Solis, Deye, Goodwe, SMA, and others. Refer to BYD’s Minimum Configuration List for specifics. Supports on-grid, on-grid with backup, and off-grid applications, ideal for solar self-consumption, emergency backup, and off-grid systems. Performance and Applications:High-Powered Backup: Capable of supporting high-powered emergency backup and off-grid functionality, suitable for critical loads. Self-Consumption Optimization: Enhances energy efficiency for residential and commercial solar systems by storing excess PV energy. Operating Temperature: -10°C to +50°C, with charge derating between -10°C and +5°C for optimal performance in varied climates. C2P Technology: Cell-to-pack design increases capacity, reduces volume, and extends lifespan. Installation and Maintenance:No External PDU Required: Simplifies setup for smaller systems, though a BMU is required for inverter communication and larger configurations. Easy Installation: Modular 3U design with plug-and-play connections for quick setup by qualified professionals. Maintenance: BMS diagnostics and modular design facilitate troubleshooting and maintenance. Warranty:Standard Warranty: 10 years, subject to conditions outlined in BYD’s Battery-Box Premium Limited Warranty Letter. Additional Features:High Energy Density: Compact design delivers high storage capacity, ideal for space-constrained installations. Bespoke Project Support: Perfect for custom and integrated systems, offering flexibility for unique energy storage needs. Eco-Friendly: Cobalt-free LFP chemistry supports sustainable energy solutions
